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 ...

Bird-window collisions: A comprehensive dataset for the Neotropical region. [PDF]

Ecology
Abstract Our primary objective was to compile a comprehensive dataset on bird–window collisions throughout the Neotropical region, including both published and unpublished sources. On May 12, 2020, we extensively disseminated invitations to provide data via email and social media platforms.

Accelerando and crescendo in African penguin ecstatic display songs. [PDF]

Ann N Y Acad Sci
Human music is often characterized by accelerando—the progressive speeding up of notes—but quantitative investigations of accelerando in other species are lacking. We used a suite of rhythm analyses to show that male African penguins produce ecstatic display songs that get progressively faster (i.e., accelerando) and louder (i.e., crescendo). This work

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 ...

Onto the sense of smell in macaws, amazons and toucans: can they use volatile cues of fruits to make foraging decisions?

Integrative Zoology, Volume 18, Issue 4, Page 762-771, July 2023., 2023
We found that scarlet macaws, keel‐billed toucans, and yellow‐throated toucans can rely on olfactory cues to locate food sources. Abstract Over the past decades, empirical evidence has been accumulated indicating that olfactory information plays a fundamental role in bird life history.

Establishment, Characterization, and Cryopreservation of Feather Follicle Fibroblast Lines From Hyacinth Macaw (Anodorhynchus hyacinthinus). [PDF]

Cell Biol Int
ABSTRACT Cryopreservation, biobanking, and in vitro propagation of cells from endangered species represent key strategies for advancing biodiversity conservation. The Hyacinth Macaw (Anodorhynchus hyacinthinus), a flagship avian species of the Brazilian Pantanal, is among the critically vulnerable taxa that stand to benefit significantly from such ...

Prioritizing species conservation programs based on IUCN Green Status and estimates of cost‐sharing potential

Conservation Biology, Volume 37, Issue 3, June 2023., 2023
Abstract Over 1 million species around the world are at risk of extinction, and conservation organizations have to decide where to invest their limited resources. Cost‐effectiveness can be increased by leveraging funding opportunities and increasing collaborative partnerships to achieve shared conservation goals. We devised a structured decision‐making

Long‐term variability of the coastal ocean stratification in the Gulf of Naples: Two decades of monitoring the marine ecosystem at the LTER–MC site, between land and open Mediterranean Sea

Marine Ecology, Volume 44, Issue 3, June 2023., 2023
Abstract We analyze 20 years (2001–2020) of temperature and salinity profiles at the LTER–MC coastal station in the Gulf of Naples, Mediterranean Sea. Surface and bottom layers show weak increases of temperature (+0.01±0.01 and +0.03±0.02°C/year, 2005–2019); water‐columns budgets (heat, freshwater) show pseudo‐periodic oscillations every 3 to 5 years ...

Characterization of antimicrobial resistance profiles in Escherichia coli isolated from captive mammals in Ecuador. [PDF]

Vet Med Sci
Among 90 E. coli isolates from 70 mammals, significant resistance was found to ampicillin (52.22%), ceftriaxone (42.22%) and cefuroxime (42.22%), with 27.78% being ESBL‐producing. Notably, 66.67% of isolates showed resistance to at least one antibiotic, and 35.56% exhibited multiresistant phenotypes.
