A new weevil species (urn:lsid:zoobank.org: act:2D5E9E4A-A250-4D0A-AF69-CF4753436686), Pseudopilolabus othnius Poinar, Brown and Legalov, sp. nov. (Coleoptera: Attelabidae), is described from Dominican amber. The new species is close to the extant P. viridanus (Gyllenhal, 1839) and P. splendens (Gyllenhal, 1839) but differs by having a bronzed body, narrower and more convex elytral...
Epidemics of infectious diseases often occur in predictable limit cycles. Theory suggests these cycles can be disrupted by high amplitude seasonal fluctuations in transmission rates, resulting in deterministic chaos. However, persistent deterministic chaos has never been observed, in part because sufficiently large oscillations in transmission rates are uncommon. Where they...
Models of the Fisher‐Lande process (FLP) have been used successfully to explore many aspects of evolution by sexual selection. Despite this success, quantitative tests of these models using data from sexual radiations are rare. Consequently, we do not know whether realistic versions of the FLP can account for the extent...
Transcriptome and genome data from twenty stony coral species and a selection of reference bilaterians were studied to elucidate coral evolutionary history. We identified genes that encode the proteins responsible for the precipitation and aggregation of the aragonite skeleton on which the organisms live, and revealed a network of environmental...
Hydrology is the main environmental filter in aquatic ecosystems and may result in shared tolerances and functional traits among species in disparate ecosystems. We analyzed the associations between taxonomic and functional facets of diversity within aquatic ecosystems (ponds vs. streams) across a hydroperiod gradient (1–365 d) to untangle the hydrologic...
Trait-mediated indirect interactions (TMIIs) are an important component of food web structure and dynamics. We determined whether TMIIs occur in rocky tidepool communities on the west coast of the USA. In the laboratory, both adults and juveniles of the keystone predator Pisaster ochraceus and adults of a smaller predatory seastar...
