Diet of the Brown Skua (Stercorarius antarcticus lonnbergi) at Hope Bay, Antarctic Peninsula: differences between breeders and non-breeders
(Springer, 2019-02)
Top predators exhibit a critical role in ecosystem functioning and in the stability of the food web, so research on diet is relevant to understand their foraging behavior. Seasonal variation in diet and prey selection may ...
Leachate from microplastics impairs larval development in brown mussels
(Pergamon-Elsevier Science Ltd, 2016)
Microplastic debris is a pervasive type of contaminant in marine ecosystems, being considered a major threat to marine biota. One of the problems of microplastics is that they can adsorb contaminants in extremely high ...
Can the colors of beach-stranded plastic pellets in beaches provide additional information for the environmental monitoring? A case study around the Port of Santos, Brazil
(Islamic Azad Univ, Tonekabon Branch, 2022-02-22)
Plastic pellets are granules of different polymers used in the manufacture of various plastic products. Plastic pellets can reach the environment due to losses after their manufacturing process, especially the transportation. ...
Non-homogeneous distribution of steroids in fecal pellets: An example in brown brocket deer (Mazama gouazoubira) with progesterone metabolites
(2019-10-01)
Measuring reproductive hormones in feces has become an important tool in the endocrine characterization of wild animals’ reproduction. However, several factors may influence its success, such as fecal collection and storage ...
Variation in diet composition during the breeding cycle of an Antarctic seabird in relation to its breeding chronology and that of its main food resource
(Springer, 2014-11)
This work had two aims related to the diet of brown skuas (Stercorarius antarcticus lonnbergi) breeding at Laurie Island (South Orkney Islands, Antarctic). The first aim was to explore whether there are changes throughout ...
Specific, Sensitive, and Stable Reporting of Human Mesenchymal Stromal Cell Chondrogenesis
(2019)
Chondrogenesis is critical to the development and repair of not only articular cartilage but also bone. Preclinical studies suggest that defects in both tissues can be repaired using culture-expanded chondroprogenitor ...
Trophic interactions between brown and south polar skuas at Deception Island, Antarctica
(Springer, 2012-02)
It is broadly accepted that the brown skua (Stercorarius antarcticus lonnbergi) competitively excludes the south polar skua (S. maccormicki) from penguin colonies when breeding sympatrically, forcing the latter to feed on ...
