Environmental Toxicology, EarlyView.ABSTRACT Mining plays a crucial role in economic development, but improper management can lead to severe environmental degradation. Particularly for iron ore, mining generates vast amounts of tailings often stored in unstable dams. This study aims to investigate the toxicological impacts of environmentally relevant concentrations of metals mixture ...

Sperm competition and ejaculate economics
Biological Reviews, 2010 Sperm competition was identified in 1970 as a pervasive selective force in post‐copulatory sexual selection that occurs when the ejaculates of different males compete to fertilise a given set of ova. Since then, sperm competition has been much studied both empirically and theoretically.

Wildlife Biology, EarlyView.After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Journal of Avian Biology, 1994 continued with the trip. On getting home late that night I put the corpse in the fridge and the next morning, some 20 hours after I'd found the bird, I dissected out its testes and seminal glomera a sperm store at the end of the vas deferens which forms the cloacal protuberance in male passerines. To count the total numbers of spermatozoa I diluted the

Journal of Animal Ecology, EarlyView.Genetic correlations have strong implications for species coexistence and their evolution. Studies addressing this issue generally tackle traits associated with competition for food and those underlying reproductive interference separately, whereas it is clear that the interaction among these is key to understand the ecology and evolution of closely ...

Ecology and Evolution, 2018 A mismatch in synchrony between male and female gamete release in external fertilizers can result in reduced or failed fertilization, sperm competition, and reduced paternity.

Journal of the Royal Anthropological Institute, EarlyView.Amid the general sense of worry that large language models will soon drown out human voices, some researchers are optimistic that machine learning will allow humans to listen to and understand animal voices to an unprecedented extent. As part of a broader project aimed at interspecies communication, a loosely connected set of animal behaviourists, AI ...
