Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean
Remote Sensing in Ecology and Conservation, EarlyView.The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

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 ...

The adaptive function of masturbation in a promiscuous African ground squirrel.
PLoS ONE, 2010 Studies of animal mating systems increasingly emphasize female multiple mating and cryptic sexual selection, particularly sperm competition. Males under intense sperm competition may manipulate sperm quantity and quality through masturbation, which could

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.

Rheotaxis facilitates upstream navigation of mammalian sperm cells [PDF]
, 2014 A major puzzle in biology is how mammalian sperm maintain the correct swimming direction during various phases of the sexual reproduction process. Whilst chemotaxis may dominate near the ovum, it is unclear which cues guide spermatozoa on their long ...

Functional variation in butterfly egg pore traits: The potential role of climate
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Immobile eggs of terrestrial animals are exposed to variable environmental conditions. Insect egg pores, critical for gas exchange (aeropyles) and fertilisation (micropyles), are ecologically important yet understudied.

Data from: A cost for high levels of sperm competition in rodents: increased sperm DNA fragmentation
, 2016 Sperm competition, a prevalent evolutionary process in which the spermatozoa of two or more males compete for the fertilization of the same ovum, leads to morphological and physiological adaptations, including increases in energetic metabolism that may ...

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.
