Abstract Understanding how human-mediated environmental change affects biodiversity is key for conserving evolvability. Because the most severe impacts are ongoing, such an understanding proving exceptionally difficult to attain. Islands natural, replicated experiments that serve as proxies habitat fragmentation and, therefore, allow us use historical changes in under Island Biogeography Theory (IBT) predict consequences of immediate anthropogenic on functional trait evolution. Rattlesnake...
Synopsis Selection on heritable phenotypic variation has played a prominent role in shaping the remarkable adaptations found across Tree of Life. Complex ecological traits, such as snake venoms, are thought to be products selection because they directly link fitness and survival. Snake venom increases efficiency prey capture processing is thus likely under intense selection. While many studies have investigated relationship between diet, primarily focused medically relevant front-fanged...
Well-documented natural history allows for thorough study of a species' ecology and evolution. However, inadequate data hamper such studies many species. For example, diet plays major role in the evolution species traits, but quantitative dietary information is often lacking groups. Garter snakes (Thamnophis) have been used as model organisms numerous studies, including focused on feeding evolution, these lack compilation records. To fill substantial gap, we amassed nearly 10,000 records 32...
Legumes utilize a long-distance signaling feedback pathway, termed Autoregulation of Nodulation (AON), to regulate the establishment and maintenance their symbiosis with rhizobia. Several proteins key this pathway have been discovered, but AON is not completely understood.
Abstract Islands have played a key role in our understanding of rapid evolution. A large body literature has examined morphological changes response to insularity and isolation, which yielded useful generalizations about how animals can adapt live very small geographic areas. However, the evolution variation insular populations often requires detailed data sets on longitudinal patterns growth development, such studies typically necessitate long‐term mark‐recapture sample individuals....
Understanding the proximate and ultimate causes of phenotypic variation is fundamental in evolutionary research, as such provides substrate for selection to act upon. Although trait can arise due selection, importance neutral processes sometimes understudied. We presented first reference-quality genome Red Diamond Rattlesnake (Crotalus ruber) used range-wide 'omic data estimate degree which adaptive shaped venom evolution. characterized population structure found substantial genetic...
Summary Two symbiotic processes, nodulation and arbuscular mycorrhiza, are primarily controlled by the plant’s need for nitrogen (N) phosphorus (P), respectively. Autoregulation of Nodulation (AON) Mycorrhization (AOM) both negatively regulate their respective processes share multiple components - plants that make too many nodules usually have higher AM fungal root colonization. The protein TML (TOO MUCH LOVE) was shown to function in roots maintain susceptibly rhizobial infection under low...
The Baja California Peninsula has over 250 islands and islets with many endemic species. Among them, rattlesnakes are the most numerous but also one of least studied groups. study island rattlesnake venom could guide us to a better understanding evolutionary processes description novel toxins.
