Unexpected trophic diversity in the endemic fish Orestias chungarensis in a high‐altitude freshwater ecosystem, Lake Chungará (4520 m), northern Chile

Journal of Fish Biology, EarlyView.
Abstract Orestias chungarensis Vila & Pinto, 1986 is a small‐bodied (max fork length = 120 mm) cyprinodontiform fish with a very restricted global distribution. The species is limited to a single, small (283 km2), high‐altitude (4520 m) catchment located in the Altiplano of northern Chile. Until the late 20th century, O.

Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

Journal of Anatomy, EarlyView.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Exploring the effects of anthropogenic habitat change on Euplerid carnivore occupancy in a humid evergreen forest, south‐east Madagascar

Journal of Zoology, EarlyView.
We collected camera trap data of small carnivores in Tsitongambarika Nouvelle Aire Protégée, south‐east Madagascar, and detected four endemic Euplerid species, that is, Cryptoprocta ferox, Fossa fossana, Galidia elegans, and Galidictis fasciata, and three non‐native species, that is, Viverricula indica, Canis familiaris, and Felis sp.

Matera: A not so ordinary H5 chondrite breccia with very low density and high porosity

Meteoritics &Planetary Science, EarlyView.
Abstract On the evening of February 14, 2023, at 17:58 UT, a fireball was detected by three cameras of the Italian PRISMA network (FRIPON network). The first samples of the Matera meteorite, collected 3 days after the fall, lay on the balcony of a private home.

Investigating Harvest and Vessel Traffic Exposure as Drivers of Social Group Characteristics in Canadian Beluga (Delphinapterus leucas) Populations

Marine Mammal Science, EarlyView.
ABSTRACT Assessing variation in social behaviors of group‐living animals may provide insight into the impacts of population stressors. Using very high resolution (VHR) satellite imagery acquired over 3 years, we compared social group size and composition, as well as spatial and social cohesion in three beluga (Delphinapterus leucas) populations that ...

Host‐feeding preferences of Culex pipiens and its potential significance for flavivirus transmission in the Camargue, France

Medical and Veterinary Entomology, EarlyView.
We identified Culex pipiens bloodmeals at the species level in natural, agricultural and peri‐urban habitats and calculated host preferences based on forage ratios. This analysis showed Passeriformes, and in particular Columba livia, Passer montanus and Turdus sp., to be the preferred Cx. pipiens hosts.
