Past exploitation of California sea lions did not lead to a genetic bottleneck in the Gulf of California
(Ciencias Marinas, 2010)
Human exploitation can lead to genetic bottlenecks associated with reduced genetic variability and lower fitness. The population of California sea lions (Zalophus californianus) in the Gulf of California, Mexico, was hunted ...
Evidence of a genetic bottleneck in an El Nino affected population of South American fur seals, Arctocephalus australis
(CAMBRIDGE UNIV PRESS, 2009)
The South American fur seal, Arctocephalus australis, was one of the earliest otariid seals to be exploited by humans: at least 6000 years ago on the Atlantic coast and 4000 on the Pacific coast of South America. More than ...
Evidence of bottleneck effect on hepatitis C virus transmission between a couple under interferon based therapy
(2017-01-01)
Issues on the correlation of viral genetic diversity and treatment response to the hepatitis C infection remain uncertain. The bottleneck effect dictates the characteristics of the viral population that will establish the ...
Active particles with desired orientation flowing through a bottleneck
(Nature Publishing Group, 2018-06)
We report extensive numerical simulations of the flow of anisotropic self-propelled particles through a constriction. In particular, we explore the role of the particles' desired orientation with respect to the moving ...
Genetic structure and evidence of anthropogenic effects on wild populations of two neotropical catfishes: Baselines for conservation
(2018-01-01)
Genetic diversity and structure of Pseudoplatystoma corruscans and P. reticulatum, large migratory SouthAmerica catfishes, where overfishing and the construction of numerous dams in their feeding and reproducing areas are ...
Mitochondrial phylogeography of the land snail Cornu aspersum: Tracing population history and the impact of human-mediated invasion in austral South America
(2013)
Aim: Study one of the most widespread biological invasions by reconstructing the molecular phylogeographic history of non-native populations of the land snail Cornu aspersum in austral South America. Specifically, we wished ...
Evolutionary history of the kelp gull (Larus dominicanus) at the south hemisphere supported by multilocus evidence
(Springer, 2016-05)
The high dispersal ability of seabirds and theabsence of geographical barriers has led to high gene flowand reduced population differentiation. Nevertheless, somespecies with philopatric behavior have restricted gene ...
Genetic Diversity of New World Crocodilians
(Springer, 2020)
Genetic diversity is one of the most important attributes of any population; it is defined as the variation in the amount of genetic information within and among individuals of a population, species, assemblage, or community. ...
Bottlenecks in domestic animal populations can facilitate the emergence of Trypanosoma cruzi, the aetiological agent of Chagas disease
(Royal Society Publishing, 2015)
Faeces-mediated transmission of Trypanosoma cruzi (the aetiological agent of Chagas disease) by triatomine insects is extremely inefficient. Still, the parasite emerges frequently, and has infected millions of people and ...
Bamboo thickets alter the demographic structure of Euterpe edulis population: A keystone, threatened palm species of the Atlantic forest
(2016-01-01)
The rapid spread of bamboos can strongly affect forest structure by interfering plant regeneration and reducing local biodiversity. Considering that bamboos exert a negative influence on the plant community, our main goal ...
