Development of short-target primers for species identification in biological studies of Carnivora. [PDF]
Ecol Evol, 2023 Abstract Noninvasive genetic sampling greatly facilitates studies on the genetics, ecology, and conservation of threatened species. Species identification is often a prerequisite for noninvasive sampling‐based biological studies. Due to the low quantity and quality of genomic DNA from noninvasive samples, high‐performance short‐target PCR primers are ...

Combined threats of climate change and contaminant exposure through the lens of bioenergetics
Global Change Biology, Volume 29, Issue 18, Page 5139-5168, September 2023., 2023 Climate change is transforming bioenergetic landscapes, challenging energetic homeostasis. Exposure to chemical contaminants may compound this threat. We reviewed the literature for evidence of interactive effects between climate change‐sensitive environmental variables and chemical contaminant exposure within five bioenergetic domains.

Diversity and Distributions, Volume 29, Issue 2, Page 316-334, February 2023., 2023 Abstract Aim Greenland is one of the places on Earth where the effects of climate change are most evident. The retreat of sea ice has made East Greenland more accessible for longer periods during the year. East Greenland fjords have been notoriously difficult to study due to their remoteness, dense sea ice conditions and lack of infrastructure.

Geographic distributions shape the functional traits in a large mammalian family
Ecology and Evolution, Volume 11, Issue 19, Page 13175-13185, October 2021., 2021 We used bears as a model system, and collected and reanalyzed data from the available literature to explore how geographical distribution shapes the functional traits of animals. This is the first time to use the species within a family to explore the relationships between geographic distribution and functional traits of animals and demonstrate the ...

Towards a Taxonomically Intelligent Phylogenetic Database [PDF]
, 2007 This note outlines some of the key intellectual obstacles that stand in the way of creating a usable phylogenetic database. These challenges include the need to accommodate multiple taxonomic names and classifications, and the need for tools to query ...

Environmental DNA, Volume 2, Issue 4, Page 460-476, October 2020., 2020 Several barcode loci targeting teleost fish and elasmobranchs have previously been developed, but to date primer sets focusing on other marine megafauna, such as marine mammals, have received less attention. Similarly, there have been few attempts to identify potentially “universal” barcode loci which may be informative across multiple marine ...

Veterinary Medicine International, Volume 2020, Issue 1, 2020., 2020 Diets currently provided to captive North American river otters (Lontra canadensis) are highly variable with different institutions providing various whole foods, commercial complete prepared diets, or combinations of both. This study investigated the digestible energy intake, gastrointestinal transit time, and digestive efficiency of three different ...

Individual variation in pup vocalizations and absence of behavioral signs of maternal vocal recognition in Weddell seals (Leptonychotes weddellii) [PDF]
, 2012 Individually stereotyped vocalizations often play an important role in relocation of offspring in gregarious breeders. In phocids, mothers often alternate between foraging at sea and attending their pup.

NAMMCO Scientific Publications, 2001 The importance of a given host to a particular parasite can be determined according to three different criteria: host preference, host physiological suitability and host contribution to transmission. Most studies on the sealworm Pseudoterranova decipiens

Inventaire systématique et paléoécologie des mammifères marins de la Mer de Champlain (fin du Wisconsinien) et de ses voies d’accès [PDF]
, 1988 À la fin du Wisconsinien supérieur, entre environ 12 400 et 9300 BP, la Mer de Champlain a inondé une vaste région allant de Québec au lac Ontario. Dans ces eaux progressivement dessalées, riches en plancton et poissons, plusieurs espèces de baleines ...
