Population genetic structure revealed by a school of the freshwater migratory fish, Brycon hilarii
(Universidade Católica de Valparaíso, 2012-01-01)
It is believed that different genetic populations of migratory fishes can co-exist in a single hydrographic system. Although different populations may occupy and explore the river together, they segregate during the spawning ...
Genetic diversity of Rhizoctonia solani AG-3 from potato and tobacco in North Carolina
(2002-05-01)
Anastomosis group 3 (AG-3) of Rhizoctonia solani (teleomorph = Thanatephorus cucumeris) is frequently associated with diseases of potato (AG-3 PT) and tobacco (AG-3 TB). Although isolates of R. solani AG-3 from these two ...
Inbreeding effects in Solanum lycocarpum A. St.-Hil populations, an endangered species of the Brazilian Cerrado
(Funpec-editoraRibeirao PretoBrasil, 2013)
Comparison of the population structure of the fiddler crab Uca vocator (Herbst, 1804) from three subtropical mangrove forests
(2004-03-01)
The population structure of U. vocator was investigated during a one-year period in three mangrove forests in southeast Brazil. The study specifically addressed comparisons on individual size juvenile recruitment and ...
Diffusive dispersal in a growing ungulate population: guanaco expansion beyond the limits of protected areas
(Springer, 2018)
Growth of wild ungulate populations within protected areas can cause an expansion towards surrounding non-protected areas and lead to conflicts with human activities. The spatial and demographic structure of colonizing ...
Linkage Disequilibrium and Population Structure in Wild and Cultivated Populations of Rubber Tree (Hevea brasiliensis)
(Frontiers Media Sa, 2018-07-03)
Among rubber tree species, which belong to the Hevea genus of the Euphorbiaceae family, Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell. Arg. is the main commercial source of natural rubber production worldwide. Knowledge ...
Using tree population size structures to assess the impacts of cattle grazing and eucalypts plantations in subtropical South America
(2010-03-08)
To evaluate the effects of distinct management of the matrix in which forest fragments are found upon plant populations thriving in forest remnants in south Brazil, we assessed the conservation status of populations of ...
The population genetic structure of Rhizoctonia solani AG-3PT from potato in the Colombian Andes
(2013-08-01)
The soilborne fungus Rhizoctonia solani anastomosis group 3 (AG-3PT) is a globally important potato pathogen. However, little is known about the population genetic processes affecting field populations of R. solani AG-3PT, ...
