Global warming facilitates the nesting of the loggerhead turtle on the Mediterranean coast of Spain

Animal Conservation, Volume 26, Issue 3, Page 365-380, June 2023., 2023
Average summer sand temperature (July 20th–August 10th) at 40 cm deep in Spanish Mediterranean beaches, as reconstructed from air temperature at El Prat beach, has increased from 1950 to 2019 (top figure). As a result, the duration of the viable nesting window for loggerhead turtles (bottom figure) has also increased and the thermal environment has ...

Genetic variation among sea turtle life stages and species suggests connectivity among ocean basins

Ecology and Evolution, Volume 12, Issue 11, November 2022., 2022
Regional genetic differentiation based on mitochondrial DNA (mtDNA) occurs in migratory species with natal philopatry such as sea turtles. To assess connectivity among sea turtle life stages and ocean basins, we (1) genotyped juveniles sampled in the Gulf of Mexico from the rarely observed dispersal stage; (2) estimated rookery contributions using a ...

Morphology of ctenostome bryozoans: 5. Sundanella, with description of a new species from the Western Atlantic and the Multiporata concept

Journal of Morphology, Volume 283, Issue 9, Page 1139-1162, September 2022., 2022
Sundanellid ctenostomes are a little investigated group of ctenostome bryozoans of ambiguous phylogenetic affiliation. In this study, we describe the soft‐body morphology of sundanellids from two localities, Singapore and Florida, to find characters elucidating the detailed anatomy of these animals and find characters supporting its relationship to ...

Identification of the Gulf of Mexico as an important high‐use habitat for leatherback turtles from Central America

Ecosphere, Volume 12, Issue 8, August 2021., 2021
Abstract Endangered leatherback sea turtles (Dermochelys coriacea) are wide‐ranging, long‐distance migrants whose movements are often associated with environmental cues. We examined the spatial distribution and habitat use for 33 satellite‐tracked leatherbacks from nesting beaches on the Caribbean coast of Costa Rica and Panama from 2004 to 2018, an ...

Research trends in U.S. national parks, the world's “living laboratories”

Conservation Science and Practice, Volume 3, Issue 6, June 2021., 2021
Abstract U.S. national parks are essential public assets for preserving natural and cultural resources and for decades have provided natural laboratories for scholarly research. However, park research, and how it may be biased, has not been inventoried at a national scale.

Dropstones in the Mar del Plata Canyon Area (SW Atlantic): Evidence for Provenance, Transport, Distribution, and Oceanographic Implications

Geochemistry, Geophysics, Geosystems, Volume 22, Issue 1, January 2021., 2021
Abstract A variety of gravel‐ to cobble‐sized rocks, recovered from the Mar del Plata (MdP) Canyon area (Western South Atlantic at 38°S) and interpreted as ice‐rafted debris, represent the first evidence that large icebergs have floated in the Falkland (Malvinas) Current from the southern polar high latitudes far northward.
