Typing for brown trout LDH-C1* alleles together with microsatellites by automated sequencing
Springer Science and Business Media LLC - Tập 9 - Trang 1669-1671 - 2008
The eye-specific lactate dehydrogenase (LDH-C1) locus is a genetic marker of evolutionary and ecological interests for brown trout. We developed a new protocol to genotype the point mutation responsible for this polymorphism by automated sequencing. To that end, we designed and employed two primer pairs in a single polymerase chain reaction, each pair including one allele-specific primer. This new...... hiện toàn bộ
Genetic analysis of salt-marsh sedge Carex scabrifolia Steud. populations using newly developed microsatellite markers
Springer Science and Business Media LLC - Tập 10 - Trang 1361-1364 - 2008
Nine microsatellite loci were isolated and characterized from the clonal salt-marsh sedge Carex scabrifolia, and genetic diversities within four populations were analyzed. The number of alleles per locus ranged from 2 to 7, with an average of 4.7. The observed and expected heterozygosities ranged from 0.000 to 1.000 and 0.000 to 0.679, respectively. In two populations, almost all polymorphic loci ...... hiện toàn bộ
Development of 19 polymorphic microsatellite loci for the intermediate horseshoe bat, Rhinolophus affinis (Rhinolophidae, Chiroptera)
Springer Science and Business Media LLC - Tập 10 - Trang 709-711 - 2008
The intermediate horseshoe bat (Rhinolophus affinis) is a widespread species in Southeast Asia. We developed 19 novel microsatellite loci from an enriched genomic library of the bat, and tested their polymorphism using a single population from Guangdong province, southern China. The number of alleles ranged from 3 to 15 per locus with the expected and observed heterozygosity ranging from 0.397 to ...... hiện toàn bộ
Disturbance of the indigenous gene pool of the threatened brook lamprey Lethenteron sp. S by intraspecific introgression and habitat fragmentation
Springer Science and Business Media LLC - Tập 10 - Trang 29-43 - 2008
Artificial introduction and habitat fragmentation affect the indigenous gene pools of fluvial animals. To investigate the effect of human activities on the genetic population structure of vulnerable brook lamprey Lethenteron sp. S in a single river system, samples from 12 tributaries of the Jinzu River, Japan, were analyzed using mitochondrial and microsatellite DNA markers. Exogenous Lake Biwa (J...... hiện toàn bộ
Patterns of genetic diversity in the red squirrel (Sciurus vulgaris L.): Footprints of biogeographic history and artificial introductions
Springer Science and Business Media LLC - Tập 5 - Trang 167-179 - 2004
British S. vulgaris are classified as aseparate subspecies, S. v. leucourus, tomainland Europe. While S. vulgaris is notunder threat across most of its Eurasian range,in Britain, Ireland and Italy populations aredeclining, mainly due to the introduction ofthe American grey squirrel (S.carolinensis). In this study, we conducted anextensive survey of mitochondrial DNA variationin British S. vulgaris...... hiện toàn bộ
Genetic diversity and its effect on fitness in an endangered plant species, Dracocephalum austriacum L.
Springer Science and Business Media LLC - Tập 11 - Trang 773-783 - 2009
The aim of this study was to estimate genetic diversity and assess its importance for plant fitness in a species belonging to the most endangered species in Europe, Dracocephalum austriacum L., and to select the most valuable populations for conservation of genetic diversity within the species in the studied regions. We analyzed allozyme variation of 12 populations in three distinct regions (Czech...... hiện toàn bộ
Genotyping-by-sequencing reveals the effects of riverscape, climate and interspecific introgression on the genetic diversity and local adaptation of the endangered Mexican golden trout (Oncorhynchus chrysogaster)
Springer Science and Business Media LLC - Tập 21 Số 5 - Trang 907-926 - 2020
Optimized DNA extraction methods for encysted embryos of the endangered fairy shrimp, Branchinecta sandiegonensis
Springer Science and Business Media LLC - Tập 10 - Trang 1777-1781 - 2008
The San Diego fairy shrimp Branchinecta sandiegonensis is a federally endangered species endemic to vernal pools in southern California, USA. Filling events in these habitats are highly variable, with some pools failing to hold water long enough for reproduction over many successive years. Studies of this species are thus hindered by the relatively rare appearance of aquatically active life histor...... hiện toàn bộ
History matters: contemporary versus historic population structure of bobcats in the New England region, USA
Springer Science and Business Media LLC - Tập 20 - Trang 743-757 - 2019
Habitat fragmentation and genetic bottlenecks can have substantial impacts on the health and management of wildlife species by lowering diversity and subdividing populations. Population genetic comparisons across time periods can help elucidate temporal changes in populations and the processes responsible for the changes. Bobcats (Lynx rufus) are wide-ranging carnivores and are currently increasin...... hiện toàn bộ
The common ground in landscape effects on gene flow in two newt species in an agroecosystem
Springer Science and Business Media LLC - Tập 24 - Trang 807-826 - 2023
Maintaining habitat connectivity is crucial for maintaining genetic diversity and reducing the risk of inbreeding depression in numerous species. Human-modified habitats pose a threat to population persistence, particularly for amphibians that require both aquatic and terrestrial habitats and often exhibit low dispersal capacity. In this study, we investigated the genetic structure and variation o...... hiện toàn bộ
