The factors leading to the extraordinary diversity of bees genus Andrena Fabricius, second most speciose among bees, remain largely unknown. To examine pattern diversification in this genus, we investigate species boundaries within controversial proxima-complex using a dataset ultra-conserved elements and various delimitation analyses (admixture analyses, BPP, DAPC). Our results confirm presenc...

Abstract An understanding of the migratory connectivity between breeding and nonbreeding areas is fundamental to management long-distance migrants under pressure from habitat change along their flyways. Here we describe evidence for genetic structure within range endangered Arctic-Canadian rufa subspecies Red Knots (Calidris canutus). Using blood tissue samples major regions in Argentina (Tierr...

Las especies animales que viven en poblaciones pequeñas con áreas de distribución reducidas pueden ser especialmente vulnerables a la pérdida y fragmentación del hábitat. Investigamos estructura genética las tuzas (Thomomys bulbivorus), una especie endémica valle Willamette, Oregon, zona muy afectada por el desarrollo humano. Analizamos diversidad genética, así como influencia paisaje flujo gen...

Euterpe precatoria is a palm tree belonging to the Arecaceae family, occurring in Western and Central Brazilian Amazonia. Its fruit, which very appreciated Amazon region, produces pulp that consumed fresh form. production carried out almost exclusively by extractive farmers. In order establish adequate strategies sustain this genetic resource, we need knowledge about diversity structure natural...

4-hydroxyisoleucine (4-HIL) is a potential drug for diabetes and weight control. 4-HIL was produced by expressing ido gene in L-isoleucine (Ile)-producing Corynebacterium glutamicum. But L-lysine (Lys) also accumulated as the main by-product this recombinant strain SN02. To attenuate Lys synthesis, two genes synthetic pathway, i.e., ddh encoding diaminopimelic acid dehydrogenase lysE specific e...

Capirona (Calycophyllum spruceanum Benth.) is a tree species of commercial importance widely distributed in South American forests that traditionally used for its medicinal properties and wood quality. Studies on this have been focused mainly properties, propagation, growth. However, genetic studies capirona very limited to date. Currently, it possible explore diversity population structure fas...

This study builds upon the current understanding of green turtle population genetic structure in Pacific that has largely been based on mitochondrial DNA (mtDNA), by examining nuclear (nDNA) diversity, regional connectivity, and male-mediated gene flow. A total 1,111 nesting samples were analyzed with 10 microsatellite markers from 20 rookeries. Population differentiation (F ST ) was significan...

A study was conducted to estimate the diversity that exists among three rabbit populations adapted South-Eastern part of Nigeria. Blood samples were collected from 75 matured, mixed-sex, and unrelated breeds selected across zone. Eight microsatellites (Sol30, Sol33, Sol44, Sat3, Sat7, Sat8, Sat12, INRA) markers used for study. These uniformly distributed genomes genotyping. Subsequently, geneti...

Brewing yeasts of the genus Saccharomyces are either available from yeast distributor centers or from breweries employing their own "in-house strains". During the last years, the classification and characterization of yeasts of the genus Saccharomyces was achieved by using biochemical and DNA-based methods. The current lack of fast, cost-effective and simple methods to classify brewing yeasts t...

In South Africa, cheetah (Acinonyx jubatus) occur as a relictual, unmanaged population of ‘free-roamers’, managed metapopulation across fenced reserves, and in various captive facilities. To ensure that the Cheetah Metapopulation Project (CMP) is not at risk losing overall genetic variation to drift or inbreeding, we propose interventions, including exchanges between free-roamers supplementatio...
