Bat Tongues and Foraging: Linking Morphology to Hunting Strategies

On their dorsal surface, bat tongues show a raised muscular structure called mediodorsal lobe (MDL) or lingual prominence. It exhibits different mechanical papillae across species, which we hypothesized are linked to foraging strategies. We predicted that tall MDLs and prominent papillae pointing frontward would effectively trap prey items caught on the wing by aerial hawkers. We examined 904 high-resolution, c...

To improve or not to improve? The dilemma of “bat-friendly” farmland potentiall...

Conventional agriculture occupies a substantial portion of Earth’s terrestrial surface and adversely affects biodiversity through pesticide spread, mechanisation, and loss of spatial and temporal heterogeneity of farmed landscapes. Consequently, conventional agriculture has become a primary target of many restoration projects operating at various scales, from habitat to landscape. While these restoration effort...

Agriculture and Water Availability Show Contrasting Effects on Bats in a Medite...

With their unique ecosystems and evolutionary dynamics, small islands offer fascinating contexts to explore animal diversity. Island bats are key players in maintaining ecological balance. However, their populations are threatened worldwide, necessitating comprehensive research and conservation strategies. Pantelleria, a small Mediterranean island and a biogeographic crossroad between Europe and Africa, offers ...

MAMMALS IN PORTUGAL: A data set of terrestrial, volant, and marine mammal occur...

Mammals are threatened worldwide, with 26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mam mals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems func tionality and resilience, and theref...

Fields of experience or field of the experience?

The theme of this article is the fields of experience, which, since 1991, and also in the "National indications...", argue, in an original way, about the offering of knowledge from the Italian early childhood school. It intends to show how the “Indications” are the provisional result of a long and potent tendency to didacticize the early childhood school, shaping it to the evaluative logics of the school that f...

Extinctions of introduced game species on oceanic islands: curse for hunters or...

Social calls are subject to stabilizing selection in insular bats

Aim Bats communicate by emitting social calls, and these often elicit reactions in conspecifics. Many such vocalizations are species-specific so that unambiguous signals can be transmitted and interpreted by conspecifics. In species-rich assemblages, evolutionary pressures might prompt interspecific diversification of call structure so that communication with heterospecifics is avoided. In species poor island c...
