Open, Grassand Forb-Dominated (OGFD) ecosystems, including tundra, tropical grasslands and savanna, provide habitat for both wild and domesticated large ungulate herbivores. These ecosystems exist across a wide temperature gradient from the Arctic regions to the Equator, but are confined to a narrow set of moisture conditions that range from arid deserts to forest-dominated systems. Primary pro...

Our aim was to model the current and future potential global distribution of Chloris truncata (windmill grass) based on the plant's biology, soil requirements and colonisation success. The growth response of C. truncata to constant temperatures and soil moisture levels were measured and estimated respectively, to develop parameters for a CLIMEX bioclimatic model of potential distribution. The n...

Climate change during the past five decades has impacted significantly on natural ecosystems, and the rate of current climate change is of great concern among conservation biologists. Species Distribution Models (SDMs) have been used widely to project changes in species' bioclimatic envelopes under future climate scenarios. Here, we aimed to advance this technique by assessing future changes in...

A comparative study of human-landing catches (HLCs) and odor-baited entry traps (OBETs) for sampling malaria vectors was conducted in two different bioclimatic areas of Senegal, the Sahelian and Sudano-Guinean phytogeographic zones, from September to December 2002. Mosquitoes were collected by the two methods both indoors and outdoors. The reliability of OBET samples was tested by comparing the...

This study evaluates the relative influence of social vs bioclimatic factors on cross-national variation in the magnitude of spring suicide peaks. Time series and cross-sectional data for 28 countries are analyzed using bivariate plots and simple correlation. Suicide seasonality (both overall and specifically as manifest by the presence of a sizeable spring peak) is positively correlated with s...

Bioclimatic design can effectively affect the environmental thermal comfort level through changing surface of study area. Using Zhengzhou Beach Park as a case study, impact three different bioclimatic methods (changing pavement only, only and both design) on outdoor comfort, temperature, relative humidity, wind speed under Envi-met model is quantitatively analysed. The results show that schemes...
