Relationship Value, Emotion, and Uncertainty Shape Conflict-Resolution Communication in a Wild Primate. [PDF]

Ann N Y Acad Sci
Geladas combine vocal−visual signals and tactile patterns to resolve conflicts. Reconciliation is rapid, mainly aggressor‐initiated, and shaped by relationship value, risk, emotion, and audience context. Post‐conflict sequences increase in complexity with stronger bonds, greater distress, dominance asymmetries, and genetic unrelatedness. These patterns

Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing. [PDF]

Anim Genet
ABSTRACT Assessing genetic structure across ocean basins is essential to understand connectivity and guide conservation in data‐deficient open‐water sharks. In this study, we examined the population genomics of Squalus cf. mitsukurii by analyzing tissue samples collected from two distant regions: California, USA (Pacific Ocean) and Pernambuco, Brazil ...

Morphological Evaluation of the Hip Joint and Pelvic Limb Bones of the Lowland Tapir (Tapirus terrestris Linnaeus, 1758) Using Radiography and Computed Tomography. [PDF]

Anat Histol Embryol
ABSTRACT The study aimed to characterize, through imaging examinations—including radiographs and computed tomography—the hip joint and the bones of the thigh, leg and feet in Lowland tapirs (Tapirus terrestris). Ten pelvic limbs were collected, two from juveniles and the remaining from adults. The femoral head exhibited a rounded morphology with a well‐

Development of Microsatellite Markers for Ex Situ Management of the Harpy Eagle Using Next Generation Sequencing. [PDF]

Zoo Biol
ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.

Congenital renal hypoplasia and contralateral kidney failure in a giant otter (Pteronura brasiliensis) ex situ in Southeastern Brazil

Brazilian Journal of Veterinary Pathology, 2023
Renal hypoplasia is incomplete development of the kidneys, in which fewer than normal numbers of nephrons are present at birth. This report is the first of these conditions in mustelids.

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

Marine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

Marine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...
