Breeding origins of a uniquely regular migrant songbird in the Galápagos Islands. [PDF]

open access: yesEcol Evol, 2023
Little is known about the causes and consequences of alternative pathways flown by long‐distance migratory birds. Using population genetic analyses, we compared samples from migratory Bobolinks stopping over in Galapagos with samples from seven locations across their breeding distribution to determine the migrant's breeding population of origin ...

Evaluating the social and ecological effectiveness of partially protected marine areas. [PDF]

open access: yesConserv Biol, 2021
Abstract Marine protected areas (MPAs) are a primary tool for the stewardship, conservation, and restoration of marine ecosystems, yet 69% of global MPAs are only partially protected (i.e., are open to some form of fishing). Although fully protected areas have well‐documented outcomes, including increased fish diversity and biomass, the effectiveness ...

Isoform specificity of progesterone receptor antibodies. [PDF]

open access: yesJ Pathol Clin Res, 2017
Abstract Progesterone receptors (PR) are prognostic and predictive biomarkers in hormone‐dependent cancers. Two main PR isoforms have been described, PRB and PRA, that differ only in that PRB has 164 extra N‐terminal amino acids. It has been reported that several antibodies empirically exclusively recognize PRA in formalin‐fixed paraffin‐embedded (FFPE)

Seasonal Variation in Fatty Acid and Amino Acid Composition of the Patagonian Marine Polychaete Abarenicola pusilla and Its By‐Products

open access: yesAquaculture Research, Volume 2023, Issue 1, 2023., 2023
This study aims to provide a quantitative analysis of the amino acids (AAs) and fatty acids (FAs) found in by‐products of the Patagonian marine polychaete Abarenicola pusilla. Samples of polychaetes were taken in different seasons and processed to generate three by‐products: eviscerated whole body, press cake, and press liquid.

Warming of aquatic ecosystems disrupts aquatic–terrestrial linkages in the tropics

open access: yesJournal of Animal Ecology, Volume 90, Issue 7, Page 1623-1634, July 2021., 2021
Using tank‐bromeliads, the authors experimentally investigated for the first time how aquatic–terrestrial linkages are affected by warming in the tropics. In contrast to temperate regions, warming is predicted to cause strong declines in tropical aquatic insect emergence into terrestrial ecosystems, while variably affecting terrestrial detritus ...

Foxed intra- and interspecific differentiation in Leptogorgia (Octocorallia: Gorgoniidae). A description of a new species based on multiple sources of evidence

open access: yesScientia Marina, 2017
The challenges of delimiting and identifying marine invertebrate species impede estimations of true biodiversity. This is particularly true in the case of gorgonian diversity, in which only classical morphological characters (e.g. branching pattern, size

Cnidae variability in Balanophyllia europaea and B. regia (Scleractinia: Dendrophylliidae) in the NE Atlantic and Mediterranean Sea

open access: yesScientia Marina, 2005
Traditionally and for practical reasons, skeleton structure has been the main source of taxonomic characters for scleractinian systematics, whereas information from soft tissues has been comparatively neglected.
