Mountain lion (Puma concolor) depredation incidents on livestock herds were recorded at 15 ranches in southern Brazil from 1993 to 1995. Maximum losses to mountain lions were 78% for goats, 84% for sheep, and 16% for cattle. Cattle mortality arising from causes other than depredation assumed a greater importance in herd productivity. In contrast, a...

The puma (Puma concolor, Carnivora: Felidae), extinct from considerable extensions of its former distribution, is considered threatened in south, southeast and northeast Brazil. Areas in the south and southeast have only recently been recolonized by the species, following decrease in logging activities after depletion of the Atlantic rainforest in...

Entre los años 2013 y el 2017, siete (n=77) interacciones de pumas con comunidades rurales fueron registradas, cuatro (n= 4) de las cuales incluyeron ataques a animales domésticos, y donde la respuesta de la comunidad fue la persecución y muerte del puma. En los otros tres (n 3) registros, no se reportaron daños a rebaños, y los pumas fueron captur...

The Arabian Leopard Panthera pardus nimr is considered Critically Endangered by the IUCN and published information about this subspecies is scarce. We assessed the status of the species on the border of one of the most important remnants of its current range, the Dhofar mountain range. In this border area, the relative abundance of leopards (0.067...

The puma is and extremely adaptable creature, being able to live in such different environments as humid jungles, high alpine meadows and deserts. In this preprint 'hint' we display some of the desert environments where the species is known to inhabit, but in a forthcoming publications the presence of puma in the Sechura Desert of Peru, as well as...

Information on martial arts may often be mislead by beliefs rather than guided by knowledge. It is not all about fighting nor it is all about misticism. This book links Tai Chi's philosophical approach with both well being, emotional inteligence and martial application (self defense). Link: https://www.amazon.com/dp/1731059981

Abstract Biosphere Expeditions and WWF Indonesia ran their second joint expedition with volunteers in and around Bukit Rimbang Bukit Baling Wildlife Reserve (BRBBWR), Riau Province, Sumatra, Indonesia, from 17 July to 12 August 2016.

A research station (Las Piedras Biodiversi...

Abstract There are indications that bear, wolf and lynx population numbers in the Slovak Republic as published by official sources, and based on counts by hunters, may be unreliable. As harvesting quotas for bears and wolves are based on these estimates, they have a very significant conservation impact. With the aim of collecting biological infor...

The Guarani Aquifer is a significant groundwater reserve in South America. In the city of Lages, a considerable extension of recharge areas of the Botucatu Sandstone, that make up the Aquifer, is under urban occupation. We observed the presence of human occupation on or near the recharge areas, irregular occupation and building of a road in protect...

Abstract The Arabian Leopard Panthera pardus nimr is a flagship species for Oman’s mountain habitats. It is classified by IUCN as Critically Endangered and is listed on Appendix 1 of the convention on International Trade in Endangered Species (CITES) having disappeared from most of its former range on the Arabian Peninsula. Most of the remaining w...

This manual is a product of several years of sampling mammals during short- term expeditions, all over the world and in particular in Brazil, Peru and the Middle East. The procedures adopted here, by maximising sample sizes and sampling effort, are meant to enable scientists to make sound ecological inferences even during short sampling periods. Fu...

Biting behaviour of pumas at the moment of killing their prey is mentioned in the literature as being delivered either to the throat, nape of the neck and base of skull. Detailed anatomic descriptions of it are, however, largely absent in literature. In this article, the biting behaviour of a puma while attacking a peccary is described based on the...

It is not known whether impacts of climate change may grow so intense as to threaten permanently the economic sustainability of countries. In this article, the mid-term impact of climate change was modeled for countries ranked amongst the most vulnerable to climate change. The Gross National Income (GNI) growth rates of three countries highly vulne...

Capillaria hepatica was detected by histopathologic diagnosis in two cougars that were shot in April 2008 in Painel, Santa Catarina, Brazil. Macroscopic analysis of their livers revealed the presence of diffuse granulomas, and the histopathologic analysis indicated the presence of C. hepatica eggs, surrounded by mononuclear inflammatory cell infilt...

Two independent attacks of mountain lions Puma concolor (Linnaeus, 1771) on different canid species are reported in this note. One of the canids was a sub-adult captive maned wolf Chrysocyon brachyurus (Illiger, 1815), revealing skull damaged by canine tooth perforation and several bruises along the body. Examination of the wounds and the killing s...

Loss of jaguar range in one of the most threatened ecosystems in the world is reported herein. Records of the last individuals shot reveal that the jaguar has suffered a loss of historical range at an estimated rate of one latitudinal degree every 10 years in its southern range in the Atlantic Rain Forest of Brazil. The chronological order of the r...

The native grasslands in the micro-region of Lages are the natural habitat of the pampas deer, and the locality of Coxilha Rica, known for its short grass, is its largest refuge in the state of Santa Catarina. Recent novel records of the pampas deer in this state are published here for the first time, as well as evidence of a reduction in its histo...

Flies of the genus Lipoptena belong to the phylum Arthropoda, class Insecta, order Diptera, and to the Hippoboscidae family. There are 30 species in Brazil, classified into 10 genera. However, there is still little information about their distribution and hosts across Brazilian regions (GRACIOLLI & CARVALHO, 2003). The genus Lipoptena feeds on bloo...

Abstract The Arabian leopard Panthera pardus nimr has disappeared from much of its former range on the Arabian Peninsula so that today populations are limited to the most remote areas. Previous Biosphere Expeditions studies in 2006 and 2007 have suggested the existence of a remnant population on the Omani side of the Musandam peninsula. The Musand...

The environmental impact generated by power plants, the low quality of reports and the delays in licensing during their implementation have been subject of debates in the Plateau of Santa Catarina and in other regions of Brazil. In this study, errors and omissions in eight reports of 15 hydroelectric enterprises in the Plateau of Santa Catarina wer...
