Environmental Toxicology, EarlyView.ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

Development of a reliable PCR‐based protocol for molecular sexing of king vultures Sarcoramphus papa
Wildlife Biology, EarlyView.The king vulture Sarcoramphus papa is a large Neotropical scavenger that lacks external sexual dimorphism, complicating demographic, ecological, and conservation studies. Reliable sex identification is therefore essential, particularly for wild and managed populations. In this study, we assessed and optimized a PCR‐based molecular sexing protocol for S.

Journal of Animal Ecology, EarlyView.This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...
