Abstract Introduction Desert fishes are vulnerable to anthropogenic environmental alterations that degrade habitat and reduce water availability, but these same fishes benefit from restoration actions that reverse the causes of decline. Ash Meadows speckled dace (Rhinichthys osculus nevadensis) is a federally endangered minnow endemic to the Mojave ...

ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Dog attacks on wild desert tortoises: A risk model
Domestic dogs attack and severely injure wild desert tortoises at the urban and ex‐urban interface with deserts. Severe trauma to tortoises increased 4 times to shell and limbs and 16.5 times to the gular horn over the decades between the 1970s and 2000s. Tortoises were at exponential risk of severe trauma when living within 12 km of settlements, towns,

We investigated nest predation in the endangered Canarian houbara bustard using 229 artificial nests and camera traps. Ravens were identified as the main predators, and predation rates were influenced by raven density, vegetation cover, stone cover, and road density.

Ravens ( Corvus corax) are indifferent to the gains of conspecific recipients or human partners in experimental tasks [PDF]
Although cooperative behaviours are common in animals, the cognitive processes underpinning such behaviours are very likely to differ between species.

Interesting breeding cases of the Raven (Corvus corax) in Hungary [PDF]
Abstract Due to conservation measures, the breeding population of the Raven significantly strengthened over the last decades in Hungary, also nesting on the lowlands. Nowadays, observing large flocks is not rare. Compared to other European countries, the urbanization of the species began relatively late in Hungary, in the ‘90s, first ...

Gaze sensitivity: function and mechanisms from sensory and cognitive perspectives [PDF]
Sensitivity to the gaze of other individuals has long been a primary focus in sociocognitive research on humans and other animals. Information about where others are looking may often be of adaptive value in social interactions and predator avoidance ...

Static boundaries of protected areas failed to capture the Canary Islands stonechat's shifting distribution patterns. Abstract Protected areas represent cornerstones of biodiversity conservation on oceanic islands, yet their effectiveness for endemic species remains poorly evaluated. We assessed how various territorial protection categories conserve an
