Effects of Density and Food Availability on the Growth of Captive‐Reared Eastern Hellbenders

Zoo Biology, EarlyView.
Our experiments demonstrate that food is the major factor limiting captive‐reared Hellbender growth and that increasing rearing density to the tested levels does not negatively impact growth. Implementing these changes may result in larger, more robust Hellbenders and increase the success of reintroduction programs.

Soil and microbial responses to wild ungulate trampling depend more on ecosystem type than trampling severity

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...

No gain from pain: Lack of nociceptor activation suggests no adaptation for defence in the evolution of European viper venoms

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Snake venoms show variability in composition at all taxonomic levels, both within and between species, and the selective pressures underlying this variation have long been debated.

Urban oases relax desiccation risk for an arid‐adapted lizard

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Urbanization from expanding human development has radically altered the structure, ecology and microclimate of landscapes worldwide. These dramatic environmental alterations subject organisms to novel ecological conditions and may select for distinct ecophysiological ...

Precipitation shapes colour polymorphism in a widespread spider

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Colour polymorphism, the presence of multiple colour variants within a population, is a common example of intraspecific phenotypic variation and has served as a model for studying drivers of diversity.
