Results showed that the larvae of the two pollinator species consume similar numbers of seeds, and that adults deposit similar numbers of eggs per flower. In obligate pollination mutualisms (OPMs), female pollinators move pollen between the flowers of a single plant species and oviposit eggs within the female flowers that they visit. Comments have to be approved before they are shown here. We have evaluated and rejected the validity of this Seasonality Hypothesis for the Florida strangling fig, Ficus aurea, near its northern range limit. Ficus tubulosa (Moraceae), a new Amazonian species and the re-establishment of Ficus trachelosyce Phytotaxa 170: 207-212. Molecular techniques are revealing increasing numbers of morphologically similar but co-existing cryptic species, challenging the niche theory. Ajna Fern Experimental manipulations of syconia to produce only seeds or various combinations of wasps confirmed this finding. Coevolution and Constraints in a Neotropical Fig - Pollinator Wasp Mutualism (Costa Rica). Order Rosales. 100% Upvoted.

CAUSES AND CONSEQUENCES OF WITHIN-TREE PHENOLOGICAL PATTERNS IN THE FLORIDA STRANGLING FIG, FICUS AUREA (MORACEAE), Biometry. Making bonsai from scratch-Ficus pertusa. The natural histories of several predators are described: an ant that feeds on wasps arriving to oviposit, moth and weevil larvae that destroy wasps as they develop within the fruits, a staphylinid beetle that feeds on mature wasps before they leave the fruits, and a group of birds that gleans wasps as they leave. Dado el gran número de especies de bibosi presentes en Bolivia y el (2) Is the mean seed production per syconium higher in the larger forest fragments? Ficus pertusa has the lighter bark; the darker one is probably F. trigonata.Photo: Mark Dimmitt : Canopies of the pair of figs in the image at left. Hence, few pollinators were available to enter third crop figs and they mostly aborted, resulting in two generations of pollinating wasps each year, plus a partial third generation. Wanneer je zijn kluit nooit laat uitdrogen en goed voor hem zorgt kan het een schitterende (en grote) plant worden. Furthermore, it has been assumed that female syconium receptivity stops quickly after pollinator visitation. Then, we will be able to reconstruct evolutionary history characters of host specificity in both genera, which will allow us to understand how these characters diversified within these groups of insects. Until recently, it was assumed that there was a short window of time during which a fig crop could be pollinated. 2 hours ago. At the site where both pollinators were present, we used sticky traps to capture the emerged fig wasps and identified species identity using mitochondrial DNA COI gene. Het kost hem namelijk veel energie om weer te wennen aan zijn nieuwe plek. These wasps reproduce within enclosed inflorescences called syconia, which develop into fruit after pollination. We found that Ficus altissima is exceptional, because it has persistent tight-fitting bud covers that prevent its Eupristina altissima pollinator (and a second species of 'cheater' agaonid) from entering its figs for several days after they start to be attracted. explore the asymmetrical interaction in the classic ‘fig–fig wasp’ co-evolution model system and show how such asymmetricinteractions may produce meta-populations.

This centuries-old subtropical Ficus Pertusa tree, known in Mexico as a Nacapule tree, has hundreds of aerial roots that have wrapped themselves around a brick wall. Kingdom Plantae. Missouri Botanical Garden. Furthermore, some, In plant species with an obligate species-specific pollinator, gamete encounter is a critical phase in the success of reproductive strategies. The pollinator wasps Tetrapus sp. O estudo foi desenvolvido durante o período de abril a julho de 2004 em Manaus e Presidente Figueiredo, Estado do Amazonas. share. The synchrony of arrival and departure of pollinators from the fig trees probably make them the species least vulnerable to predation. landmarks library. web interface by We suggest that host repression through the active regulation of bract closure, which can create interference competition among the foundresses and prevent extra more foundresses sequential entry in fruit cavities, would help the figs avoiding the cost of over-exploitation. Female agonid wasps, pollinators of monoecious figs, on entering a syconium (foundresses) are trapped in it and are committed to share the limited resources (flowers) with other foundresses. A population whose average period of flowering cycle is half that of another population can sustain a wasp population with milkyway landmarks library. on the evolution of dioecy from monoecy in Ficus. las distintas especies de bibosi está el proporcionar una fuente de alimentación a varias especies frugívoras de la fauna silvestre. The differential development of syconia, which was influenced by mutualistic or parasitic progeny, accordingly contributed to within-tree reproductive asynchrony.4. Species Details; Observations; Maps; Photos; Sounds; Statistics; On/in; Names; I've seen this species! Diversity of Plants and Animals in Thung Yai Naresuan Wildlife Sanctuary, Tak Province. Special constraints can govern symbiont community membership, function and structure and symbiont persistence in such metacommunities. Developing larvae of early-ovipositing wasps may hasten syconium ontogeny through formation of earlier and larger nutrient sinks, whereas larvae of late-arriving parasites may lengthen syconium ontogeny to complete their development successfully. Because developing wasps feed on some developing seeds, constraints on seed maturation (especially resource availability) may inevitably affect wasp maturation as well. aerial library. We compared phenologies of fig wasp emergence and host flowering at sites where one or both pollinators were present. Ficus pertusa is a semievergreen to evergreen tree with a wide, dense, pyramidal crown; It usually grows around 4 - 12 metres tall but there are records of plants up to 30 metres tall with a huge, wide crown and numerous aerial roots and trunks. Adult life spans of only one or two days characterise life cycles of the fig wasps (Agaonidae) that pollinate fig trees (Ficus spp., Moraceae). Trees up to 25 m tall. Leaves lanceolate, elliptic or ovate, with acuminate or acute apex. Ficus pertusa L.f. is an accepted name This name is the accepted name of a species in the … For these two species, receptivity lasted from 2 to 3 wk. 26 Nov 2020 Sort by. - Oikos 49: 261-268. Our experiments showed that syconia of both species are able to extend their receptive period for a few days longer when visited only by a single wasp. Symbionts exhibit a diversity of interactions ranging from mutualism to parasitism. wasps represent an interesting model for studying the evolution of host specialization, due to the high specificity of its association with Ficus (Moraceae) and their diversified life histories and degrees of host specialization. We found that within-tree asynchronous flowering benefits some non-pollinating wasps, lower tree density is preferred by pollinators and parasitic wasps, precipitation negatively impact pollinators and parasitic wasps, and that higher temperature benefit pollinators and disfavor parasitic wasps. Taxonomy. Ficus pertusa. These results offer valuable insights into host density requirements for maintaining symbionts, and have implications for multitrophic symbiont community stability. The absence of direct tradeoffs in success between partners helps explain the great evolutionary success of the fig pollination mutualism. Plants involved in OPMs frequently host various non‐pollinating seed parasites and parasitoids that may influence the outcome of the mutualism. Based on these results we propose a new hypothesis, as a possible scenario, The Ficus pertusa is on the right. C. fusciceps lay mainly male eggs first then female eggs. © 2008-2020 ResearchGate GmbH. Figs edible, globose, 0.8-1.2 cm in diameter. In the present study we intend to analyze the evolution of host specificity in two genera of Neotropical Agaonidae: the pollinators Pegoscapus Cameron, 1906, and the non-pollinators Idarnes Walker, 1843. y Bouche y F. catappifolia Kunth. The female fig wasp (Blastophaga silverstrii, Agaonidae) distributes pollen within the inflorescences of the fig (Ficus pertusa, Moraceae), then lays eggs in florets whose ovaries are accessible to her ovipositor. However, some fig species show distinct within-tree flowering asynchrony. Hence, pollination of figs was Crops of individual trees were most, not least, synchronous during the coldest, driest months of 2 years. Entre los roles ecológicos más importantes de Plant reproductive phenology is generally viewed as an individual's strategy to maximise gamete exchange and propagule dispersal, and is often considered largely dependent on patterns of floral initiation. Genus Ficus. Specificity at different stages in the interaction was studied in a common neotropical fig, Ficus pertusa L., particularly in relation to its sympatric congener F. tuerckheimii Standley. The demonstration of a long duration of female receptivity has important consequences for understanding the maintenance of the fig-wasp mutualism. Species: Ficus pertusa Collected by: Oviedo-Brenes, Federico Collector Number: 3620 Identified by: Oviedo-Brenes, Federico Latitude: 8.947 Longitude:-82.8392 Elevation(m): 1457 : Per page: 1 of 3 Small Medium Large. French National Centre for Scientific Research, Staying in the club: Exploring criteria governing metacommunity membership for obligate symbionts under host–symbiont feedback, A non‐pollinating moth inflicts higher seed predation than two co‐pollinators in an obligate pollination mutualism. Species-specificity of pollination is maintained because F. pertusa evidently releases a species-specific chemical to attract pollinators. 2.Movements between trees, Maintenance of Species-Specificity in a Neotropical Fig: Pollinator Wasp Mutualism. Ficus pertusa L.f. References . We found that older pollinators produced fewer and smaller offspring, but seed production was more efficient. The lack of tradeoffs in success between partners also meant a lack of tradeoffs between male and female components of reproductive success for the fig, because wasp offspring are the only possible pollen vectors. 0 comments. This can happen in one of two ways in fig systems: a) failure to pollinate syconia that often leads to their abortion, ... Mutualisms are relationships of mutual exploitation in which both species receive a net benefit from their interaction, ... Esto se produce cuando los siconos se encuentran receptivos. of the 'fine-tuned traits' appear to be be preadaptions - traits that existed before the mutalism was establised. Forest fragmentation can reduce population size, affecting the plant species and their biological interactions. Global Biodiversity Information Facility. Berg, C.

Leaves lanceolate, elliptic or ovate, with acuminate or acute apex. individual syconia was believed to last only a few days. Se incluye información obtenida en la bibliografía existente sobre el tema, además de datos recolectados en varios sitios boscosos que cuentan con poblaciones de bibosis. All female flowers have the potential to produce either seeds or galls and variation is merely one of gross morphology. receptivity to wait for a wasp if no wasps are available. 99% of pollinators arriving at sticky traps on flowering figs were the specialist species. Pl. duration of the, Figs and fig wasps form one of the best known examples of species-specific mutualism and coevolution. A unique obligatory symbiosis exists between Ficus capensis Thunb., and its pollinator, Ceratosolen capensis Grandi. While the one-to-one specificity of the fig - pollinator mutualism is often discussed in reviews of coevolution, the means by which specificity of the interaction is enforced and the frequency of pollinator errors have not been examined.

Competition between co‐occurring pollinator species is predicted to increase pollinator virulence, i.e. Adding wings artificially to the empty syconia also deterred the foundresses from entering them, suggesting that these residual wings serve as negative feedback regulators for the preference and entry of foundresses. pollinator wasps and non-pollinating exploiter wasps). laying more eggs or consuming more seeds per fruit. earth daylight library. However, figs can effectively restrict exploiter wasps, and reward the pollinator wasps, resulting in complex asymmetric interactions among species. The Neotropical Agaonidae, Interacting species proceed in a complex environment in which ecological factors might affect each species differentially. Late-ovipositing parasitoid progeny, the presence of only seeds within the syconium, or delayed pollination increased syconium development time. 6. 1. The results show that a positive relationship between seed and wasp production could be maintained in warm season, which might be because of density dependence restraint among foundresses and their low oviposition and pollination efficiency, keeping common resource (female flowers) utilization unsaturated. The crops that attract wasps the earliest in their development are the most heavily visited ones, but mature the fewest pollinator offspring and seeds on a per-fig basis. Reproductive phenology, however, can be affected by proximate responses to pollinators, parasites and herbivores which could influence floral longevity or fruit development time.2. Selection should strongly favour wasps that avoid female figs and enter only male figs. El género Ficus L. (Moraceae) en México Botanical Sciences 90: 389-452. All rights reserved. Ken Fern, Thus, we show that pollinator wasps of fig-wasp associations choose the most suitable syconia to enter as long as they have opportunity. (4) The persistence period of a wasp population 442 1782. This opens an interesting perspective on the coevolution of figs and their pollinators and on the nature of mutualistic interactions in general. Receptive figs were produced on male plants in spring and summer, timed to coincide with the release of short-lived adult pollinators from the same individual plants. Because one of these wasps is the obligate pollinator of the fig, predation may have a strong impact on successful pollen donation by the plant. The size of fragments did not influence seed production [LRT P value = 0.1; LR stat (χ²) = 4.64; n = 370]. 1 released wasps earlier than those pollinated by Wiebesia sp. Ficus pertusa L.f. Ficus pertusa L.f. is an accepted name This name is the accepted name of a species in the genus Ficus (family Moraceae). We evaluated the effects of fragmentation on Ficus adhatodifolia Schott ex Spreng population, aiming to answer two questions: (1) is population size sufficient to maintain reproductive fig trees throughout the year? Min Depth 1 meters. bolivianos, al igual que de la mayoría de los bosques tropicales. Las especies más aprovechadas en Bolivia son: Ficus glabrata Kunth. It is generally believed that physical heterogeneity in common resource or evolutionary restraint can sufficiently prevent direct conflict between host and symbionts in mutualism systems.

For prey, the length of colonization windows was positively related with colonization success and symbiont persistence. The obligate pollinators of figs (Ficus, Moraceae), species-specific agaonid wasps, benefit figs only by transporting pollen between trees; larvae are seed predators.

LMC predicts less female‐bias when several foundresses reproduce in a fig due to reduced relatedness among intra‐sexually competing male offspring. Overall the mutualism benefit from lower density, lower precipitation and higher temperature. The extent to which the foundresses preferred to enter the syconia was found to be influenced by the density of wings at and around the ostiole. 1. But given the high risk of mortality in flight between trees, adult wasps should prefer to pollinate and oviposit within inflorescences (syconia) at the same tree at which they developed. One of the key factors in the success of gamete encounter, the length of female receptivity, has been rarely studied experimentally. It has been suggested that such asynchrony is an adaptation by which figs in seasonal environments can reduce pollinator mortality, by permitting wasps to persist on individual trees at times when flight would be impossible. chaos) between co-evolved species. By contrast, the seed parasite Herpystis consumed more seeds than either pollinator species, and fruit crops with a high proportion of Herpystis had significantly lower net seed production. Since syconia are known to remain receptive for extended periods of time waiting for adequate pollen receipt (Khadari et al. Delayed entry generates reproductive costs, especially for the pollinator. Using relevant empirically measured microcosm parameters, we simulate symbiont dispersal from and colonization of other host inflorescences. These compounds are shown to be released at the female phase of the fig’s flowering eyclc. of the interval periods of fig flowering is smaller, (b) the fig population size is larger, and (c) figs can prolong their Syconia pollinated at any time during this period of receptivity are capable of setting seeds. Three species of wasps (Torymidae) commensal to the mutualism are the most species-specific of these associates, probably because the timing of their development has to be closely synchronized with the pollinators' development. Ficus (Urostigma) pertusa e Ficus (Pharmacosycea) maxima. The observed fine-tuned traits involve not only coevolution but also selection acting on only one of the partners. flowering interval of fig trees is short, even a small fig population can sustain a wasp population successfully. Pollination of fig trees depends on mutualist wasps that reproduce within their flowers. Ficus pertusa Author Linnaeus f., 1782. Synthesis: Factors influencing symbiont community membership can be unique when host-symbiont feedback impacts host microcosm development. Predators inflict high mortality on the four species of wasps associated with the fig Ficus pertusa L. in Monteverde, Costa Rica. 4. For predators, the cumulative length of the colonization windows of their prey dictated their success; diet breadth or prey colonization success did not influence the persistence of predators. The fitness trade-off between fig and pollinator wasps is greatly affected by environmental or ecological variations. Predators also had a greater host-plant density requirement than prey for persistence in the community. earth night library. The prosperity of pollinator wasps will then attract more exploiters, and population increases of exploiter wasps will lead to the sanction by fig trees again. Seeds are also important nutrient sinks. Trees up to 25 m tall. Partners in mutalisms often have conflicting evolutionary goals. A mechanism of pollinator attraction is discussed and corroboration obtained by using gas chromatography to show the presence of volatile compounds. The principles and practice of statistics in biological research. Google Arts & Culture features content from over 2000 leading museums and archives who have partnered with the Google Cultural Institute to bring the world's treasures online. Name . Mutualisms are relationships of mutual exploitation, in which interacting species receive a net benefit from their association. Our data on fig/fig wasp reciprocal mutualism (Ficus racemosa), however, show that structural barriers of female flowers or genetic constraints of pollinators previously hypothesized exist, but cannot sufficiently maintain the mutualism stability. At this stage, wasps did not discriminate the two sets probably because it is not profitable any longer to choose among the syconia than to simply enter any syconium they encounter; time spent in choosing would increase the risk of their reproductive failure 1. (2) The wasp survival rate (WSR) is higher when (a) the variation We examined the influence of insect interactants on within-plant reproductive phenology in the fig–fig wasp nursery pollination mutualism in Ficus racemosa (Moraceae). A well known and ecologically important mutualism is the relation between fig trees (Ficus, Moraceae) and their specific chalcid pollinating wasps and parasitic wasps. earth realistic clouds library. In Ficus species (Moraceae), each exclusively associated with its specific pollinating wasp, the receptive female phase of, In the dioecious fig/pollinator mutualism, the female wasps that pollinate figs on female trees die without reproducing, whereas wasps that pollinate figs on male trees produce offspring. This emphasizes the importance of population-level mechanisms to explain the fig/fig wasp mutualism. receptive phases, in which wasps are available, to their total receptive phases. Maximum asynchrony occurred in seasons that were probably most favorable for wasp transit between trees. However, most trees were either very heavily pollinated or very poorly pollinated, despite evidence that pollination intensity is partially under the tree's control. These data are correlated to pollinator behaviour and visitation data obtained from field observations. were found in almost all syconium, thus, indicating that Ficus-pollinator mutualism was not lost. Description. The wings load on the ostiole was strongly correlated to the foundresses loads. Cite this page: Tropicos.org. Last update on 2019-06-13: Now containing 11906 plants. Male F. pumila produced two major crops annually, with figs receptive in spring and summer. Genus: Ficus Species: Ficus pertusa. Nursery Availability Such wasps oviposit in Ficus inflorescences. We vary host densities and symbiont colonization window lengths, and track the persistence of each symbiont species in the metacommunity based on the temporal availability of the resource and the trophic position of the symbiont. To understand the co-existence mechanism, we studied phenologies of morphologically similar species of fig wasps that pollinate the creeping fig (F. pumila) in eastern China. While different wasp species oviposit into syconia at varying times during its ontogeny, all wasp progeny are constrained to exit syconia simultaneously just prior to fruit ripening. However, for multitrophic symbiont communities that are closely associated with host plants, symbionts and hosts may additionally influence each other affecting membership criteria in novel ways.
