Abstract:The diurnal movement patterns of Triturus vulgaris, T. cristatus, Pelobates fuscus, Bufo bufo, Rana temporaria, and R. arvalis were investigated during five breeding seasons (1994)(1995)(1996)(1997)(1998). Two main questions were addressed: 1) What is the probability of an individual amphibian getting killed when crossing the road? and 2) What fraction of the amphibian populations gets killed by traffic? The rate of movement of 203 adult amphibians was recorded. Information on traffic loads was provided, and mortality risk was calculated depending on traffic loads and movement rate. The probability of getting killed ranged from 0.34 to 0.61 when crossing a road with a traffic load of 3,207 vehicles/day, and from 0.89 to 0.98 when crossing a motorway. The number of amphibians killed on the road was estimated by systematic counts. Population sizes were estimated for all ponds within 250m of the relevant highway stretch. Results indicate that about 10% of the adult population of P. fuscus and brown frogs (R. temporaria and R. arvalis) were killed annually by traffic at this site.

“…Most studies regularly count road kills from slow-moving vehicles (Hansen 1982;Drews 1995;Rosen and Lowe 1994;Mallick et al 1998), or by foot (Fuellhaas et al 1989;Munguira and Thomas 1992). These assume that every victim is observed, which may be true for large conspicuous mammals, but is certainly not true for small animals.…”

Revista Brasileira de Zoologia 22 (1) : 191-196, março 2005 Vertebrate roadkills were observed during the rainy season (June-October) during five passages along the 572 km road between Caracas and Mantecal/Apure in Venezuela, a total distance of 2860 km. Five dominant landscape types were identified along this road: 1) the Coastal Cordillera area, which includes crop fields, woods, dry savannah, and settlements; 2) non-flooded llanos with clumps of trees and palms and small bodies of water; 3) artificially watered rice plantations; 4) gallery forest along the river Apure, with a few crop fields; and 5) flooded llanos, largely drained, with many embankments and storage reservoirs. The gallery forest yielded 30 carcasses, the largest number. The greatest number of carcasses were noted in October, at the end of the rainy season.Since data on animals killed on roads by passing vehicles began to be published long ago (STONER 1925, 1935, KNOBLOCH 1939, SPRAGUE 1939, DICKERSON 1939 RESUMO.

Este trabalho apresenta uma análise de vertebrados mortos em estrada em cinco habitats tropicais diferentes na América do Sul. As observações dos vertebrados mortos em estrada foram feitas em 1978, a 572 km da rodovia entre Caracas e Mantecal/Apure na Venezuela, durante a estação das chuvas (junho-outubro). Durante cinco passagens nesta rota, a qual inclui cinco habitats diferentes, foram encontradas 79 carcaças de vertebrados -répteis e mamíferos. Assumindo que as carcaças permaneçam por dois dias na estrada, é esperado que veículos matem 350 crocodilos Caiman crocodilus Linnaeus, 1758 (Alligatoridae), durante a estação das chuvas. Cálculos similares foram feitos para outras 313 espécies de cobras e lagartos, 294 gambás Didelphis marsupialis Linnaeus, 1758 (Didelphidae), 220 raposas Cerdocyon thous (Linnaeus, 1776) (Canidae), 129 tamanduás Tamanduá tetradactyla (Linnaeus, 1766) (Myrmecophagidae), 55 capivaras Hydrochaerus hydrochaeris (Linnaeus, 1766) (Hydrochaeridae) e 37 lebres Sylvilagus floridanus Allen, 1890 (Leporidae). Numerosos trabalhos têm sido publicados sobre vertebrados mortos por veículos em estradas da Europa, Amé-rica do Norte e Austrália e vários trabalhos têm sido referências úteis sobre vertebrados mortos em estradas na África e Ásia. Da América do Sul existem vários trabalhos com vertebrados, pássaros e mamíferos, sendo que da Venezuela existe apenas um que tenha tratado de iguanas (Iguana iguana Linnaeus, 1758, Iguanidae).

“…The lessons from Mikumi National Park and other protected areas elsewhere where public roads pass across indicate negative effects and ecological impacts associated with roads. Drews (1995) reports that over 50 different animal species including endangered species have been killed by road accidents at Mikumi national park just within a two-year period of the field study. Furthermore, the author estimated a minimum of 3 kills per day during the same period.…”

Tanzania rangelands are a stronghold for biodiversity harbouring a variety of animal and plant species of economic, ecological and socio-cultural importance. Efforts to protect these resources against destruction and loss have involved, among other things, setting aside some tracks of land as protected areas in the form of national parks, nature reserves, game reserves, game controlled and wildlife management areas. However, these areas and adjacent lands have long been subjected to a number of emerging issues and challenges, which complicate their management, thus putting the resources at risk of over exploitation and extinction. These issues and challenges include, among other things, government policies, failure of conservation (as a form of land use) to compete effectively with alternative land uses, habitat degradation and blockage of wildlife corridors, overexploitation and illegal resource extraction, wildfires, human population growth, poverty, HIV/AIDS pandemic and human-wildlife conflicts. In this paper, we review the emerging issues and challenges in biodiversity conservation by drawing experience from different parts of Tanzania. The paper is based on the premise that, understanding of the issues and challenges underpinning the rangelands is a crucial step towards setting up of plausible objectives, strategies and plans that will improve and lead to effective management of these areas. We conclude by recommending some proactive measures that may enhance the sustainability of the rangeland resources for the benefit of the current and future generations.
