Field sampling of fig pollinator wasps across host species and host developmental phase: Implications for host recognition and specificity. [PDF]

Ecol Evol, 2023
We sampled fig‐pollinating wasp individuals in a natural Neotropical Ficus community, at different phases of the reproductive cycle of the host figs (e.g., trees with receptive inflorescences, or vegetative trees, bearing only leaves), and compared with other tree species, using them as non‐Ficus controls.

Rising temperatures threaten pollinators of fig trees-Keystone resources of tropical forests. [PDF]

Ecol Evol, 2022
We determine the effect of the predicted temperature increases on the lifespan of five different Neotropical fig wasps. All tested pollinator wasp species had a significantly shorter lifespan in 30, 32, 34 and 36°C compared to the current diurnal mean temperature of 26°C.

Genome-wide sequence data show no evidence of hybridization and introgression among pollinator wasps associated with a community of Panamanian strangler figs. [PDF]

Mol Ecol, 2022
Abstract The specificity of pollinator host choice influences opportunities for reproductive isolation in their host plants. Similarly, host plants can influence opportunities for reproductive isolation in their pollinators. For example, in the fig and fig wasp mutualism, offspring of fig pollinator wasps mate inside the inflorescence that the mothers ...

Pollinator and host sharing lead to hybridization and introgression in Panamanian free-standing figs, but not in their pollinator wasps. [PDF]

Ecol Evol, 2023
Deviations from strict host specificity in obligate pollination mutualisms provide opportunities for interspecific interactions between plant species, pollinator species, or both. We find fig–pollinator wasps to be well‐delimited species, deeply divergent from one another, with no evidence for hybridization or introgression.

Genomic diversity and structure of a Neotropical microendemic fig tree. [PDF]

Ecol Evol
The population genomics of Ficus pringlei (Moraceae) is analyzed to characterize neutral and adaptive genetic variation and structure and its association with geographic barriers and environmental heterogeneity. This study provides information on the diversity and the mechanisms underlying the genomic variation of F. pringlei.

A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids. [PDF]

Mol Ecol
ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.

Differential effects of nematode infection on pollinating and non‐pollinating fig wasps: Can shared antagonism provide net benefits to a mutualism?

Journal of Animal Ecology, Volume 90, Issue 7, Page 1764-1775, July 2021., 2021
This article is the first to describe the phenomenon of nematode infection of non‐pollinating fig wasp taxa and its possible role in modulating network dynamics in fig–fig wasp communities. Similar facultative mutualisms may be more widespread than currently appreciated in other Arthropod‐rich community assemblages with shared resources in ephemeral ...

Mating strategies and aggressive combat in wingless neotropical fig wasp males

Brazilian Archives of Biology and Technology, 2008
The aim of this work was to study the wingless males of pollinating (Pegoscapus tonduzi) and two nonpollinating fig wasp species, genus Idarnes, associated with figs (Ficus citrifolia) in Brazil to answer the following questions: 1) Do wingless males of ...

Structural and ultrastructural characterization of male reproductive tracts and spermatozoa in fig wasps of the genus Pegoscapus (Hymenoptera, Chalcidoidea)

Micron, 2008
The three Pegoscapus species present the same internal reproductive tract features comprising testes with a single testicular tubule, seminal vesicles, vasa deferentia, accessory glands and an ejaculatory duct. The seminal vesicle shows two morphologically distinct portions although they do not resemble the separate chambers found in other Chalcidoidea.

Transcriptome‐facilitated development of SNPs for the Sonoran Desert rock fig, Ficus petiolaris (Moraceae)

Applications in Plant Sciences, Volume 3, Issue 7, July 2015., 2015
Premise of the study: Single‐nucleotide polymorphism (SNP) primers were developed for a native North American desert fig, Ficus petiolaris (Moraceae), to provide markers for population genetic studies designed to quantify patterns of gene flow across a complex landscape.
