Vertebrate community composition and activity at giant otter latrines in the northern Pantanal

Ecosphere
Mustelids and other terrestrial carnivores use communal latrines where feces and urine serve as olfactory cues for territory demarcation and intraspecific communication.

Mitogenomic and Metabarcoding Resources for the Study and Conservation of Keystone Neotropical Raptors. [PDF]

Ecol Evol
We characterized complete mitochondrial genomes for nine keystone Neotropical raptors, including four threatened and five near‐threatened species, providing essential resources for phylogenetic and conservation studies. We also developed metabarcoding primers, enabling non‐invasive monitoring of Neotropical raptors via environmental DNA.

Foraging Observations: Novel Trophic Interactions Between the Andean Gull (<i>Chroicocephalus serrranus</i>) and Endangered Vertebrates of Lake Titicaca. [PDF]

Ecol Evol
We show that the Andean gull predates on both the Titicaca Grebe and the Titicaca Giant Frog. Both these species are critically endangered, and it was unknown that they had natural predators before this. ABSTRACT We record two new predation events and one new kleptoparasitic Andean Gull (Chroicocephalus serranus) behavior, interactions that directly ...

A general framework for modeling pathogen transmission in co-roosting host communities. [PDF]

Ecology
Abstract Cross‐species transmission of pathogens can be facilitated by frequent contact among wildlife. Cross‐species transmission is often driven by phylogenetic similarity between host species, but the role this plays when multiple host species co‐roost is unknown.

Tree-Cavity Denning of Güiña (<i>Leopardus guigna</i>) and Breeding Productivity From Camera Trap Records. [PDF]

Ecol Evol
Tree cavities are critical habitats for numerous vertebrate species. We report the first evidence of güiña breeding in a tree cavity, with insights from camera trap surveys in south‐central Chile's temperate forests. These findings enhance our understanding of the species' natural history, breeding behavior, and habitat preferences.

Use of Citizen Science to Determine Prey Partitioning Between Two Coastal Raptors. [PDF]

Ecol Evol
In Australia, Eastern Osprey (Pandion haliaetus cristatus) and White‐bellied Sea‐Eagle (Haliaeetus leucogaster) occupy the same ecological niche and are suspected of partitioning prey resources. This study investigated this through evaluating the breadth, overlap and partitioning of diets recorded from social media posts.

CHEWING LICE (Phthiraptera) FROM CRESTED CARACARA (Caracara plancus, Falconidae) IN SOUTHERN BRAZIL

Science And Animal Health, 2020
This study was carried out to detect chewing lice species occurring on Crested Caracara (Caracara plancus) in Southern Brazil between January 2014 and December 2018. For this aim, the road-kill birds were collected for parasitological studies at the Biology Institute, Department of Microbiology and Parasitology of the Federal University of Pelotas ...

Perineuronal satellite neuroglia in the telencephalon of New Caledonian crows and other Passeriformes: evidence of satellite glial cells in the central nervous system of healthy birds? [PDF]

PeerJ, 2013
Glia have been implicated in a variety of functions in the central nervous system, including the control of the neuronal extracellular space, synaptic plasticity and transmission, development and adult neurogenesis.

Rapid Global Deforestation Leaves Forest-Dependent Raptors With Half of Their Suitable Habitat Remaining. [PDF]

Glob Chang Biol
We analyzed high‐resolution global data on forest change between 2001 and 2023 within the ranges of 369 forest‐dependent raptor species. On average, these species have lost 10% of forest within their ranges since 2001. Seventy‐seven species had already lost at least 15% of additional forest cover within their ranges in the latter half of the 20th ...
