Two populations of the mosquito Psorophora columbiae from the central Andean area of Colombia and one population of Ps. toltecum from the Atlantic coast of Colombia were analyzed for 11 isoenzyme markers. Psorophora columbiae and Ps. toltecum are two of the main vectors of Venezuelan equine encephalitis. We found no conspicuous genetic differences between the two ... more

Amazona aestiva; bottleneck; Conservation; Genetic structure; Microsatellite

The blue-fronted Amazon (Amazona aestiva) is a widely distributed Neotropical parrot and one of the most captured parrots in nature to supply the illegal trade of wild animals. The objectives of the present study were to analyze the genetic structure of A. aestiva to identify management units and support conservation planning and to verified if A. aestiva populations ... more

Bothrops moojeni; conservation genetics; Genetic structure; Genetic variability; RAPD; Vipers

Bothrops moojeni is an abundant venomous snake responsible for most of the snakebite cases in the Central region of Brazil and as a result of the anthropogenic habitat disturbance, such as the increase in extensive farming, the range of B. moojeni has been greatly fragmented. Here, we obtained genomic DNA from a total of 75 snakes belonging to four populations. Genetic ... more

Jerusalem artichoke (Helianthus tuberosus) is a wild relative of the cultivated sunflower (H. annuus); it is an old tuber crop that has recently received renewed interest. We used RAPD markers to characterize 147 Jerusalem artichoke accessions from nine countries. Thirty RAPD primers were screened; 13 of them detected 357 reproducible RAPD bands, of which 337 were ... more

The population structure of the black rockfish, Sebastes inermis (Sebastidae), was estimated using 10 microsatellite loci developed for S. schlegeli on samples of 174 individuals collected from three wild and three hatchery populations in Korea. Reduced genetic variation was detected in hatchery strains [overall number of alleles (NA) = 8.07; allelic ... more

Genetic structure; Korean rockfish; Microsatellite loci; Sebastes schlegeli

The Korean rockfish (Sebastes schlegeli) is an important commercial fish that is widely used in aquaculture. We isolated and characterized 18 polymorphic microsatellite loci from the Korean rockfish using a (GT)13-enriched genomic library. Polymorphism was assessed in 48 individuals from a single population collected from the northern coastal waters of the Yellow Sea. ... more

Conservation; Effective size; Genetic structure; Lobeira; Population genetics

The inbreeding effective population size is an estimate of inbreeding and genetic drift in populations. It is an important tool for conservation genetics because it represents the number of individuals that are effectively contributing alleles to the subsequent generations. Several studies have been published in the last decades on the genetic structure of natural plant populations of the ... more

We analyzed the genetic diversity of populations of two sympatric species of Lymania (Bromeliaceae), both endemic to the Atlantic rainforest of southern Bahia (Brazil). Lymania azurea has a restricted occurrence, while Lymania smithii has a wider distribution. Our aim was to provide genetic data to contribute to the design of more efficient conservation ... more

Placusa pinearum, a newly described beetle species found living in pine shoot tunnels bored by the pine tip moth, Dioryctria rubella (Pyralidae), has potential as a vector to transport biological agents for controlling this moth pest of pine trees because of the high degree of niche overlap (co-occurrence) between them. In order to help determine the suitability of ... more

Gossypium mustelinum is the only cotton species native to Brazil; it is endemic to the semi-arid region of the northeast. The populations are found near perennial and semi-perennial sources of water, such as ponds or pools in intermittent streams. Problems with in situ conservation derive from human interference in its habitat, mainly because of excessive cattle grazing ... more
