EFFECT OF TEMPERATURE AND PARTICLE SIZE ON THE ALKALINE EXTRACTION OF PROTEIN FROM CHICKEN BONE WASTE [PDF]

, 2010
Chicken bone is a waste of chicken meat processing industry and restaurants that has not been used widely, even though it contains valuable organic compounds that are functionals, such as collagenous and non collagenous protein.

Breeding behavior and pup development of the Caspian seal, Pusa caspica [PDF]

, 2017
The Caspian seal, Pusa caspica, is an ice-breeding phocid endemic to the Caspian Sea. The breeding behavior of this species is poorly documented. Here, we report behavioral observations of 518 mother-pup pairs and 210 lone pups, made from the bridge of ...

Circumpolar Population Structure, Diversity and Recent Evolutionary History of the Bearded Seal in Relation to Past and Present Icescapes

Molecular Ecology, Volume 34, Issue 4, February 2025.
ABSTRACT The Arctic environment plays a critical role in the global climate system and marine biodiversity. The region's ice‐covered expanses provide essential breeding and feeding grounds for a diverse assemblage of marine species, who have adapted to thrive in these harsh conditions and consequently are under threat from global warming.

Gastroliths in the harp seal Phoca Groenlandica

Polar Research, 1995
An adult harp seal, caught by accident in a gill net during the peak of the seal invasions along the northern coasts of Norway (1986/87), was found to have eaten 2.466 kg of stones with masses up to 265 g. Different theories to why harp seals on occasion deliberately eat stones, with particular emphasis on the hypothesis that these may aid in the ...

Radiocarbon dates from the Netherlands and Doggerland as a proxy for vegetation and faunal biomass between 55 and 5 ka cal bp

Journal of Quaternary Science, Volume 39, Issue 2, Page 248-260, February 2024.
ABSTRACT Three hundred forty‐one radiocarbon dates from the Groningen radiocarbon database are compiled in this study. They show for the first time that organic sediment samples from the eastern Netherlands and mammal bones from Doggerland reflect shifts in the presence and the density of vegetation (food for herbivores) and mammal biomass during the ...

Shipping Through Sea Ice: Impacts on Marine Habitats and Best Practices [PDF]

, 2017
As the result of Arctic climate change and an increase in shipping season length, there is a growing interest in Arctic shipping operations. Sea ice serves as an important habitat for marine mammals, therefore, shipping through sea ice could lead to ...

In search of virus carriers of the 1988 and 2002 phocine distemper virus outbreaks in European harbour seals [PDF]

European harbour seal (Phoca vitulina) populations decreased substantially during the phocine distemper virus (PDV) outbreaks of 1988 and 2002. Different hypotheses have stated that various seals and terrestrial carnivore species might be the source of ...

Evaluating hybrid speciation and swamping in wild carnivores with a decision‐tree approach

Conservation Biology, Volume 38, Issue 1, February 2024.
Abstract Hybridization is an important evolutionary force with a principal role in the origin of new species, known as hybrid speciation. However, ongoing hybridization can create hybrid swamping, in which parental genomes are completely lost. This can become a biodiversity threat if it involves species that have adapted to certain environmental ...
