Multidirectional chromosome painting in Synallaxis frontalis (Passeriformes, Furnariidae) reveals high chromosomal reorganization, involving fissions and inversions. [PDF]

open access: yes, 2022
In this work we performed comparative chromosome painting using probes from Gallus gallus (GGA) Linnaeus, 1758 and Leucopternis albicollis (LAL) Latham, 1790 in Synallaxis frontalis Pelzeln, 1859 (Passeriformes, Furnariidae), an exclusively Neotropical ...

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

open access: yesIntegrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

The link between colorfulness and extinction risk across the world's passerine birds

open access: yesConservation Biology, EarlyView.
Abstract Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as coloration directly affect human interactions with wildlife.

Impact of global change on the distribution of mountain mammals and birds

open access: yesConservation Biology, EarlyView.
Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...

Underestimation of avian diversity in the Tumbesian hotspot: Sampling gaps and conservation challenges

open access: yesConservation Science and Practice, EarlyView.
This study provides the first comprehensive reassessment of avian diversity in the Tumbesian region in over 30 years, documenting 931 species and identifying significant sampling gaps driven by geographic accessibility. We reveal a critical misalignment between biodiversity value and current protection coverage, particularly in humid forests which ...

A redescription of Cryptosporidium galli Pavlasek, 1999 (Apicomplexa: Cryptosporidiidae) from birds [PDF]

open access: yes, 2003
Clyptosporidium galli Pavlasek, 1999, described from the feces of birds, is redescribed with additional molecular and biological data. Oocysts are ellipsoidal, are passed fully sporulated, lack sporocysts, and measure 8.25 × 6.3 μm (range 8.0-8.5 × 6.2-6.
