Loss, persistence and reversal of phenotypic traits
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Abstract Despite longstanding research on human rights and the environment, scholarship has only recently moved towards an explicit connection to the marine environment. At the same time, research on human rights and oceans focuses on people at sea, not environmental protection.

Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Occurrence and evolution of cannibal behaviour in extant snakes
ABSTRACT Extant snakes (Serpentes) are a highly diverse group of squamate reptiles, which have independently evolved key morphological adaptations to consume a large variety of vertebrate and invertebrate prey. While these predator–prey interactions have been widely addressed by several studies, little is known regarding the occurrence of cannibal ...

Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...

Antimicrobial peptides (AMPs) are promising candidates for next‐generation antibiotics, acting through mechanisms such as membrane disruption and intracellular targeting. This review examines how variations in bacterial membrane composition critically influence AMP activity.

The Influence of Climate and Livestock Grazing on Two Species of Burrowing Desert Frogs
ABSTRACT Frogs are one of the most vulnerable groups of vertebrates globally, occupying a range of environments including arid deserts. They are threatened by many interacting factors, including climate change and livestock grazing. In this study, we present the first long‐term research (over 30 years) on two arid‐dwelling frogs in Australia, the ...

We report the first predation event of a northern silky anteater by a tiger rat snake. This predation underscores how little is known about the nocturnal anteater and its predators. As the snake is commensal with humans, anthropogenic habitat alterations might have exposed the anteater to a novel predation pressure.

Island‐restricted reptiles are more threatened but less studied than their mainland counterparts
Reptiles are highly diverse on islands, yet there is no comprehensive overview of island‐restricted reptiles (IRRs) regarding their distribution, threat status, and research efforts. Our assessment revealed that despite IRRs comprising nearly a quarter of global reptile species and 30.8% being threatened, only 7.2% of the literature focuses on them ...

Boom‐Bust Dynamics Drive Community‐Wide Dietary Structuring in Desert‐Dwelling Raptors
We investigated how boom‐bust productivity dynamics affected dietary structuring within raptor communities of an arid bioregion. We found that higher productivity was associated with high dietary overlap, lower niche breadth and greater foraging on small mammals; however, raptors that were nomadic exhibited greater specialisation regardless of ...
