Distinctiveness, rarity and conservation in a subtropical highland coniferSpringer Science and Business Media LLC - Tập 13 - Trang 211-222 - 2011

Juniperus blancoi is a rare subtropical conifer with a wide yet restricted distribution and three recognized varieties. In this study, its ecological and genetic exchangeability are tested based on morphological descriptions, habitat differences, size measures, growth form, population genetics estimates and phylogeography, using the trnC-trnD plastid DNA region. Populations show d...... hiện toàn bộ
Hybridization does not currently pose conservation concerns to murres in the AtlanticSpringer Science and Business Media LLC - Tập 20 - Trang 1465-1470 - 2019

Hybridization can negatively impact one or both taxa involved and therefore pose conservation concerns. Climate change is expected to increase the rate of hybridization particularly in polar regions, and so investigating hybridization in Arctic and Antarctic species is important for conservation. Hybridization and genetic introgression have been observed between Pacific populations of thick-billed...... hiện toàn bộ
Isolation and characterization of microsatellite loci in Paspalum notatum Flüggé (Poaceae)Springer Science and Business Media LLC - Tập 10 - Trang 1977-1980 - 2009

Paspalum notatum is a forage grass recognized as one of the major constituents of the native grasslands in the New World. The knowledge of the genetic diversity and structure of P. notatum populations is fundamental for the conservation and germplasm management of this species. About 11 microsatellite markers were isolated from P. notatum and characterized in 25 accessions. The average number of a...... hiện toàn bộ
Genetic characterization of free-ranging Asiatic wild ass in Central Asia as a basis for future conservation strategiesSpringer Science and Business Media LLC - Tập 19 - Trang 1169-1184 - 2018

Loss of genetic diversity due to drift and inbreeding reduces a population’s ability to respond to environmental change and may result in inbreeding depression. The Asiatic wild ass (Equus hemionus), regionally also known as Gobi khulan, Turkmen kulan, or Persian onager, has become confined to less than 3% of its historic distribution range. Remaining populations in Central Asia outside of the Mon...... hiện toàn bộ
Contemporary and historical river connectivity influence population structure in western brook lamprey in the Columbia River BasinSpringer Science and Business Media LLC - Tập 20 - Trang 299-314 - 2018

The western brook lamprey Lampetra richardsoni (WBL) is a small non-parasitic lamprey that inhabits rivers and streams from southern Alaska to northern California. WBL remain in fresh water throughout their entire life and show limited dispersal. Although adults may migrate short distances upstream to spawn, most movement likely occurs through passive drifting of larvae downstream. Genetic differe...... hiện toàn bộ
