This study aimed to investigate the climatological impacts of air temperature, sunshine duration, and rain precipitation, in a moderate climate, on reproductive performance Romanov sheep continental part Croatia, during two consecutive years (2019-2020). Our included 549 matings with 520 successful conceptions at 5 farms, fertility rate was 94.72%. The percentage lambs delivered winter 53.27% (...
Desertification is currently a big problem in many countries, especially in developing countries, and includes natural processes and improper human activities. The present study was conducted to evaluate the potential of desertification with an emphasis on water, climate and soil criteria using IMDPA Model in Abbas plain, Ilam province with an area about 18028.8 hectare. Geometric averages for ...
Tian et al., (2004a), Oleson et al., (2003), and Tian et al., (2004b) recently identified significant differences between the current land surface parameters of the Community Land Model (CLM) used with the Community Climate System Model (CCSM), and global land surface descriptions from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite mapping. Specifically these investigations ide...
Norman Daniels, in applying Rawls' theory of justice to the issue of human health, ideally presupposes that society exists in a state of moderate scarcity. However, faced with problems like climate change, many societies find that their state of moderate scarcity is increasingly under threat. The first part of this essay aims to determine the consequences for Daniels' theory of just health when...
Ecological theory asserts that the climate of a region exerts top-down controls on regional ecosystem patterns and processes, across space and time. To provide empirical evidence of climatic controls, it would be helpful to define climatic regions that minimized variance in key climate attributes, within climatic regions—define the periods and features of climatic regimes, and then look for con...
The link between biodiversity and climate has been obvious to biologists since the work of von Humboldt in the early 1800s, but establishing the relationship of climate to ecological and evolutionary patterns is more difficult. On evolutionary timescales, climate can affect supply of energy by biotic and abiotic effects. Some of the best evidence for a link between biodiversity and climate come...
Emerging diseases are impacting animals under high-density culture, yet few studies assess their importance to wild populations. Microparasites selected for enhanced virulence in culture settings should be less successful maintaining infectivity in wild populations, as once the host dies, there are limited opportunities to infect new individuals. Instead, moderately virulent microparasites pers...
There is an urgent need for a better understanding of animal migratory ecology under the influence of climate change. Most current analyses require long-term monitoring of populations on the move, and shorter-term approaches are needed. Here, we analysed the ecological drivers of seabird migration within the framework of the energyscape concept, which we defined as the variations in the energy ...
