A new species of Begonia sect. Ruizopavonia A.DC., B. pseudodendron Moonlight & Á.J.Pérez, is described from the western slopes Andes in Colombian Department Nariño and Ecuadorian Province Carchi. The diagnosed against cymbalifera L.B.Sm. B.G.Schub. compared with other similar species. We also provide photographs, a distribution map, an IUCN conservation assessment for species, which classi...

Habitat destruction often results in the loss of biodiversity in natural communities. Vernal pools are a feature of California’s native landscape which have been heavily impacted over the past century by agricultural and urban development. Current estimates of vernal pool losses in the Central Valley range from 50-85% of pre-settlement acreages. In this paper I apply data from recent field surv...

The traditional therapeutic uses of some indigenous orchids of Bangladesh are described in this paper. Terrestrial (11) and epiphytic (18) orchids, 29 in total, are used by Bangladeshi rural and tribal people for the treatment of nearly 45 different diseases and ailments. Roots, tubers, pseudobulbs, stems, leaves and even whole plants are used. Some herbal preparations have miraculous curative ...

We analyze a mathematical model of a simple trophic web with two herbivores and one predator. The studied scenarios represent a common practice in the steppes of Argentine Patagonia, where livestock are raised in a semi-wild state, either on the open range or enclosed, coexisting with competitors and predators. We perform numerical simulations of metapopulations assemblages of the system, which...

We live in an era when everyday activities are shaped by environments that are not only artificial—almost half of humanity lives in cities—but also mediated. Emotional and cognitive activities in all levels and segments of society are increasingly vested in information-rich venues supported by television, radio, telephone, and computer networks. Even in very remote areas, hunters and farmers wa...

This project represents an interdisciplinary approach to integrating computational methods into the knowledge-discovery process associated with understanding biological systems impacted by the loss or destruction of sensitive habitats. We specifically developed bioinformatics tools for the study of (1) beach mouse communities and (2) marginal fish habitats. Data mining was used in these project...

Leopardus colocolo, Leopardus geoffroyi, Leopardus tigrinus and Puma yagouaroundi are wild feline species endangered mainly due to habitat destruction and vehicle run overs. Seventeen felines hit on the roads were collected in Southern Brazil and examined for parasites. Cestodes were identified as Mesocestoides sp. The parasites were found in the small intestine of the hosts with a prevalence o...

Just 50 years ago, large herbivores like Banteng, Asian Elephant, and Eld’s Deer as well as predators like Indochinese tiger and leopard were so abundant in the Dry Forests of North and Northeast Cambodia that scientists compared this ecoregion to the savannas of East Africa. In the troubled decades that followed, however, habitat destruction and hunting greatly reduced animal numbers and diver...

Swamp spurge (Euphorbia palustris, Euphorbiaceae) is a large perennial species of wet grassland and swamps. Its natural habitats are fragmented and isolated both naturally and owing to habitat destruction by human activity. Thus the species is endangered and legally protected in Germany. This report describes seven novel polymorphic microsatellite loci that will be helpful to characterize genet...
