figsimR: An R Package for Simulating Fig–Wasp Community Dynamics

Ecology and Evolution
Fig–fig wasp systems represent a widely applicable but underutilized framework for community assembly research, yet their multi‐trophic structure and species interactions substantially increase the complexity of community simulation.

Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila

Advanced Science, EarlyView.
While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.

Field studies reveal a close relative of C. elegans thrives in the fresh figs of Ficus septica and disperses on its Ceratosolen pollinating wasps

BMC Ecology, 2018
Background Biotic interactions are ubiquitous and require information from ecology, evolutionary biology, and functional genetics in order to be understood. However, study systems that are amenable to investigations across such disparate fields are rare.

Daily rhythm of mutualistic pollinator activity and scent emission in Ficus septica: ecological differentiation between co-occurring pollinators and potential consequences for chemical communication and facilitation of host speciation. [PDF]

PLoS ONE, 2014
The mutualistic interaction between Ficus and their pollinating agaonid wasps constitutes an extreme example of plant-insect co-diversification. Most Ficus species are locally associated with a single specific agaonid wasp species. Specificity is ensured

HOST SPECIFICITY OF FIG WASPS (AGAONIDAE) [PDF]

Evolution, 1970
For the development of seeds, the figs (Ficus spp.) are dependent upon small chalcidoid wasps of the family Agaonidae. No other means of pollination of fig flowers is available to the plant, and the wasps cannot develop anywhere except in the gall flowers of the fig.2 There has been considerable difference of opinion as to the degree of host ...

Loss, persistence and reversal of phenotypic traits

Biological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

FFW_DB: a dynamic integrated database for investigating the specialized mutualism of figs and fig wasps

Frontiers in Ecology and Evolution
The mutualistic relationship between figs (Ficus, Moraceae) and their obligate pollinating fig wasps (Agaonidae, Hymenoptera) has served as a classic model for studying coevolution and coadaptation for over 150 years.

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

Biological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

Host-plant species conservatism and ecology of a parasitoid fig wasp genus (Chalcidoidea; Sycoryctinae; Arachonia).

PLoS ONE, 2012
Parasitoid diversity in terrestrial ecosystems is enormous. However, ecological processes underpinning their evolutionary diversification in association with other trophic groups are still unclear. Specialisation and interdependencies among chalcid wasps

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...
