Codamozza-Fluker: The Compelling Case of a Flukeless Fin Whale Traveling Throughout the Mediterranean Sea and the Need for Basin-Wide Conservation Efforts. [PDF]

open access: yesEcol Evol
The authors report the first case of a live fin whale in the Mediterranean Sea with completely amputated flukes, a female which suffered two separated incidents with entanglement and collision both being hypothesized as causes. Sightings after the complete loss of her flukes enabled tracking her movements from September 2019 to July 2020, prior to her ...

Evaluating Three Modelling Frameworks for Assessing Changes in Fin Whale Distribution in the Mediterranean Sea. [PDF]

open access: yesEcol Evol
This study evaluates the effectiveness of Generalized Additive Models (GAMs), Boosted Regression Trees (BRTs), and Hurdle Models for modeling fin whale density and habitat suitability in the NW Mediterranean Sea. Key findings reveal that while all models effectively distinguished whale presence and absence, density and habitat relationships varied ...

Sex-Specific Variation in Foraging Behavior is Related to Telomere Length in a Long-Lived Seabird. [PDF]

open access: yesEcol Evol
Foraging during breeding is energetically demanding, intimately linked to breeding investment, and possibly constrained by individual condition. Telomere length, the protective nucleoproteins located at the ends of the chromosomes, is considered a trait reflecting somatic maintenance and individual quality. We found that brown booby females with longer

Fiddler Crabs (Crustacea: Decapoda: Ocypodidae) From Coastal Ecuador and the Galápagos Islands: Species Descriptions and DNA Barcodes. [PDF]

open access: yesEcol Evol
Twenty‐five taxa were collected during the surveys, while two more were noted from the literature and museum collections; five are new to Ecuador. DNA sequences for cytochrome c oxidase–subunit 1 were obtained for 27 operational taxonomic units with three morphologically indistinguishable cryptic or pseudo‐cryptic taxa were also revealed.

Genome-Wide Population Structure in a Marine Keystone Species, the European Flat Oyster (Ostrea edulis). [PDF]

open access: yesMol Ecol
ABSTRACT Ostrea edulis, the European flat oyster, was once a widespread economically and ecologically important marine species, but has suffered dramatic declines over the past two centuries. Consequently, there has been a surge in European restoration efforts, many of which focus on restocking as a conservation measure.

Vulture Exclusion Halves Large Carcass Decomposition Rates and Doubles Fly Abundance. [PDF]

open access: yesEcol Evol
We experimentally excluded vultures from pig carcasses (Sus scrofa) in Costa Rica, under different habitats and across seasons with the aim to assess the impact of vulture population decline on carrion decomposition and insect abundance. Vulture exclusion halved carcass decomposition rates and doubled fly abundance, while dung beetle abundance remained

Potencial energético del Alto Golfo de California

open access: yesBoletín de la Sociedad Geológica Mexicana, 2009
The upper part of the Gulf of Baja California, besides the ecological diversity and mineral resources, has a great potential in energy resources. In this paper it is presented a preliminary evaluation of the ideal actions in order to obtain electric energy if renewable resources were used.
