AFLP; Aquilegia; Columbine; Genetic diversity

Species of the genus Aquilegia are exceptionally diverse in their floral morphology and color, commonly known as columbine. They are widely planted ornamentals and are highly attractive for hummingbirds. However, little is known about their genetic diversity. We examined the genetic diversity of the species and cultivars using amplified fragment length polymorphism (AFLP) ... more

Abalone; AFLP; Domestication; Genetic diversity; SSCP; Stock identification

Amplified fragment length polymorphism (AFLP) analysis was carried out on representative individuals of wild Haliotis asinina using 64 primer combinations. Nine polymorphic AFLPs were cloned and sequenced. Sequence-specific primers were designed from six AFLP-derived fragments. Three sequence-characterized amplified region (SCAR) markers (HaSCAR320, HaSCAR295 ... more

AFLP; Genetic diversity; Procambarus clarkii; Yangtze River

The red swamp crayfish has become one of the most important freshwater aquaculture species in China. At present, although it is widely distributed in the middle and lower reaches of the Yangze River basin, little is known about its population genetics and geographic distribution in China. We estimated the genetic diversity among 6 crayfish populations from 4 lakes (Hongze Lake, Poyang ... more

AFLP; Colombia; Genetic diversity; Heliconia; Phylogenetic relationships

Researchers have classified the Heliconia genus as a group of highly variable and diverse plants. Species and cultivars are visually differentiated primarily on the basis of the color and size of inflorescence bracts. At taxonomic level, flower type (parabolic, sigmoid, or erect) and size are taken into account. The vast morphological diversity of heliconias at intra-specific, ... more

conservation genetics; Genetic diversity; Houbara bustard; Microsatellite markers

The Houbara bustard (Chlamydotis undulata) is a threatened avian species that is rapidly declining throughout its range, especially in North Africa, Asia and the Canary Islands. We examined the population structure and genetic variation for the three Houbara subspecies C. undulata undulata, C. u. fuertaventurae and C. u. macqueenii. A total of 266 birds ... more

Arapaima gigas; conservation genetics; Lower Amazon; Microsatellites; Multiplex polymerase chain reaction; pirarucu

The aim of the present study was the development of a multiplex genotyping panel of eight microsatellite markers of Arapaima gigas, previously described. Specific primer pairs were developed, each one of them marked with either FAM-6, HEX or NED. The amplification conditions using the new primers were standardized for a single reaction. The results obtained demonstrate high heterozygosity ( ... more

Ciconiiformes; conservation genetics; Demographic history; Heteroplasmy; Population structuring; Waterbirds

The wood stork (Mycteria americana) is a colonial wading bird that inhabits the Neotropical region from the southeastern United States (US) to northern Argentina. The species is considered to be endangered in the US due to degradation of its foraging and breeding habitat. In other parts of its range, such as in the Brazilian Pantanal region, breeding populations of this species ... more

AFLPs; conservation genetics; Genetic variability; Tropical forest fragment

Studies on intraspecific variation can contribute to the development of conservation strategies by identifying units of conservation for threatened species. Aspidosperma polyneuron is a tropical tree of seasonal semideciduous forests that is currently endangered and protected because it has been heavily logged for lumber, although it was once common in Brazil and neighboring ... more

Brazilian Atlantic forest; conservation genetics; Microsatellite; Population genetics; Tropical tree species

Cariniana legalis is one of the largest tropical trees with a wide distribution in the Brazilian Atlantic rainforest. We investigated the Mendelian inheritance, genetic linkage, and genotypic disequilibrium at seven microsatellite loci specifically isolated for C. legalis, and at two previously developed heterologous microsatellite loci. Forty to 100 open-pollinated ... more

conservation genetics; Microsatellite; Perna viridis

The green lipped mussel, also known as the Asian green mussel (Perna viridis) is a fast reproducing and valuable food source, but it is also considered an invasive species and can clog and damage pipes and marine equipment. Eight novel polymorphic microsatellite loci for P. viridis were isolated and characterized. Microsatellite polymorphism was evaluated in 30 ... more
