Behavioral Flexibility and the Conservation Value of Howler Monkey Populations in Small Habitat Patches. [PDF]

Am J Primatol
Standardized effect sizes of the relationships between predictor and response variables. Natural logarithms are denoted as “ln.” Open circles (blue outline) indicate mostly positive effects; solid circles (red filled) indicate mostly negative effects. ABSTRACT Species occupying small habitat patches and exhibiting behavioral and ecological flexibility ...

Temperature and Ultraviolet Radiation Influence the Skin Microbiome of Humpback Whales. [PDF]

Mol Ecol
ABSTRACT The skin microbiome of humpback whales harbours diverse microbial communities that play a crucial role in host skin protection and environmental interaction. However, studies on cetacean skin microbiomes in the Southern Hemisphere focus on feeding grounds, with limited information on microbiome dynamics at breeding grounds and during migration

Evaluating the protection status and exposure to warming of Caribbean reefs with high functional potential. [PDF]

Conserv Biol
Abstract Over the past decades, climate change has emerged as a major threat to global biodiversity, negatively affecting the integrity and functioning of ecosystems and the benefits they provide to people. To mitigate these impacts, it is essential to identify climate refugia that support the persistence of the structure and function of reef ...

Macroscale climate change predictions have little influence on landscape-scale habitat suitability

Perspectives in Ecology and Conservation, 2022
Although a few studies have addressed the combined effects of climate change and habitat loss on biodiversity at a regional scale, the extent to which climate change will impact species occurrence at the landscape scale remains unclear.

A new species of Odontophrynus (Anura, Odontophrynidae) from the southern portion of the Mantiqueira mountains

European Journal of Taxonomy, 2022
Using an integrative approach (morphology of the adult and larvae, bioacoustics, osteology, karyotype, and molecular data), we described a new tetraploid species of Odontophrynus to the Mantiqueira mountain range, in southeastern Brazil.
