Functional classification of the tiger moths (Erebidae: Arctiinae) of Barro Colorado Island, Panama, complements ecological insights from phylogenetic classification

Greg P. A. Lamarre, Charles N. Hackforth, Petr Blažek, Simon Tristram Segar et autres

Abstract A lack of data makes it difficult to quantify interspecific variation in response traits for most species. Estimating population trends of understudied species based on data for related taxa fails to account for functional divergence among close relatives. Responses to environmental …

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

Yiyi Dong, Simon Tristram Segar, Qingbei Weng

ABSTRACT 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. We present figsimR, an open‐source, modular R package that implements fig wasp community …

Ficus VOCs and pollinator antenna sensilla diversity

You-Cheng Chen, Jie Gao, Mingbo Chen, Yan-Qiong Peng et autres

The percentage (mean±SD) of each compound to the B phase fig volatiles of each Ficus species. The majority of compounds were identified by co-chromatography with authentic standards, by matching library suggestions (NIST) with published Kovats retention index (RI) values obtained from the …

Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism

Li Cao, Nina Joffard, Simon Tristram Segar, Daniel Souto‐Vilarós et autres

Most studies of the chemical ecology of plant-pollinator interactions emphasize the role of pollinator-mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals. To investigate whether …

The diversity of Ficus

Simon Tristram Segar, Sotiria Boutsi, Daniel Souto‐Vilarós, Martin Volf et autres

BACKGROUND: The influence of Ficus extends beyond its numbers (800 species), and fig trees are often key-stone species in their habitats. Ficus fills many tropical forest niches. The past 15 years have witnessed an explosion of research in Ficus, and its obligate …

Demography and adaptation of a species specific pollinator associated with an invasive fig tree

Li-Hua Wu, Jie Zou, Yuting Jiang, Ling Lü et autres

Some fig species introduced outside of their native range have become invasive when colonized by their obligate pollinating wasps, but how these pollinators migrated and adapted to novel environments are less studied. Here, we focus on Eupristina verticillata, the obligate pollinating wasp …

Inflorescence size predicts host–symbiont conflict in monoecious fig–wasp mutualisms

Derek W. Dunn, K. Charlotte Jandér, Edward Allen Herre, Simon Tristram Segar et autres

Abstract In monoecious fig–wasp mutualisms (Ficus; ~350 spp.), tiny wasps obligately pollinate fig-tree inflorescences (‘figs’). Although pollination enables seed production, wasp symbionts also oviposit into flowers, replacing potential seeds with wasp offspring. Consistently across Ficus, ~40–60% of developed flowers produce seeds. Although …

Genomic insights into population dynamics and adaptive strategies of the endangered dipterocarp, Hopea chinensis

Weimin Xiang, Yuting Jiang, Jie Hui Zou, Yan Deng et autres

Asian rainforests are a biodiversity hotspot and are dominated by dipterocarps. Thus, protecting endangered dipterocarp species living on the distribution boundary of dipterocarps is a central factor in maintaining the range of Asian rainforests. Despite the perceived conservation priority of these species, …

Phylogenetic structure of moth communities (Geometridae, Lepidoptera) along a complete rainforest elevational gradient in Papua New Guinea

Sentiko Ibalim, Pagi S. Toko, Simon Tristram Segar, Katayo Sagata et autres

We use community phylogenetics to elucidate the community assembly mechanisms for Geometridae moths (Lepidoptera) collected along a complete rainforest elevational gradient (200-3700 m a.s.l) on Mount Wilhelm in Papua New Guinea. A constrained phylogeny based on COI barcodes for 604 species was …

Specialist fig-consuming lepidopterans can inflict costs to plant reproductive success that are mitigated by ant bodyguards

Lisette van Kolfschoten, Miriam Adu Asantewaa, Lovisa Dück, Simon Tristram Segar et autres

Insect herbivores can inflict substantial costs on plant reproductive success. Seed herbivory impacts directly by reducing the number of seeds and therefore the dispersal and reproductive potential of the plant. Fig trees, Ficus, provide keystone resources for tropical forests. The pollinating fig …
