Cambios en el pelaje del roedor subterráneo Ctenomys talarum: posible mecanismo térmico compensatorio [PDF]
Revista chilena de historia natural, 2004 En este trabajo se evaluaron los cambios en densidad y longitud del pelaje dorsal y ventral en el roedor subterraneo Ctenomys talarum, como posible mecanismo compensatorio frente a cambios de temperatura estacionales en el ambiente de la cueva, en especial durante la epoca estival, y durante el periodo de prenez en las hembras, ya que ambas etapas ...

Immune genotypes, immune responses, and survival in a wild bird population
Molecular Ecology, Volume 32, Issue 12, Page 3044-3059, June 2023., 2023 Abstract Individuals vary in their immune genotype, inbreeding coefficient f, immune responses, survival to adulthood, and adult longevity. However, whether immune genes predict survival or longevity, whether such relationships are mediated through immune responses, and how f affects immune genotype remain unclear. We use a wild song sparrow (Melospiza

Ecosphere, Volume 13, Issue 7, July 2022., 2022 Abstract Exploring the process of diet selection will contribute to improvement in our understanding of animal foraging strategies. The overwhelming majority of ecological research on animal learning and foraging concentrates on how social learning influences the feeding styles of animals living in groups.

Preliminary investigation on enzymatic activity in saliva of Hystrix cristata L., 1758
Journal of Animal Physiology and Animal Nutrition, Volume 106, Issue 2, Page 387-394, March 2022., 2022 Abstract Mammal's saliva contains a variety of electrolytes and proteins. They carry out an important role in the digestion process, in the antibacterial and antiviral activity, in lubrication and maintenance of oral general health status. It may also contain several enzymes according to dietary habits and general wellness.

Ecological Research, Volume 36, Issue 2, Page 206-220, March 2021., 2021 The empirical relationship between mitochondrial DNA haplotype diversity and microsatellite DNA heterozygosity in 739 populations of 108 mammalian species. Haplotype diversity was higher than the theoretical prediction. Abstract The effective gene number (the number of genes that can be inherited) of mitochondrial DNA (mtDNA) is one‐fourth of that of ...

Reviewing the effects of food provisioning on wildlife immunity. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2018 While urban expansion increasingly encroaches on natural habitats, many wildlife species capitalize on anthropogenic food resources, which have the potential to both positively and negatively influence their responses to infection.

Mounting a specific immune response increases energy expenditure of the subterranean rodent Ctenomys talarum (tuco-tuco): Implications for intraspecific and interspecific variation in immunological traits [PDF]
, 2010 It was recently hypothesised that specific induced defences, which require substantial time and resources and are mostly beneficial against repeated infections, are more likely to be favoured in 'slow-living-pace' species.

Хромосомы и видообразование у туко-туко (Ctenomys, Hystricognathi, Rodentia) [PDF]
, 2016 Tuco-tucos, South American rodents of the genus Ctenomys represent an interesting model of speciation. Their strict territorial and solitary life under the earth, vast but highly fragmented habitats, low migration activity were the causes of their very ...
