Desiccation is an important limiting factor in the intertidal zone. Generally decreasing seaward, desiccation stress can also be alleviated in wet microhabitats. Juvenile snails are generally more susceptible to desiccation than adults, and, for some species, juveniles must therefore hide in microhabitats to survive emersion. The transition from hiding in safe microhabitats to being able to sur...

Shade structures are often considered as one method of reducing stress in feedlot cattle. Selection of a suitable shade material can be difficult without data that quantify material effectiveness for stress reduction. A summer study was conducted during 2007 using instrumented shade structures in conjunction with meteorological measurements to estimate relative effectiveness of various shade ma...

this study was carried out to investigate the possibility of prediction the occurrence of heat stress in dairy cows and determination of climate critical periods. the most common indexes for estimation the degree of thermal stress istemperature humidity index (thi). in this study yousef’s thi index (1985)was used to analyze the yearly and monthly effects of temperature and humidity. meteorologi...

The present paper highlights the effect of water stress (drought) on the proximate composition of the leaves of Ocimum gratissimum and Gongronema latifolium. Cultivated O. gratissimum and G. latifolium plants grown in plastic planting buckets were subjected to mild water stress by irrigating each planning bucket with 500 ml of water once in a week. In the control treatment, each bucket was supp...

Background and goals Economic considerations water shortages associated with climate change are driving the conversion of many hand-pruned furrow- or sprinkler-irrigated juice grape vineyards in arid eastern Washington to mechanical pruning drip irrigation. However, producers have traditionally avoided plant deficits, fearing a decline vineyard productivity. Methods key findings</h...

The objective of this study was to evaluate temperature/humidity conditions in freestall barns with different types of gravity ventilation and to determine the risk of heat stress in cows based on the temperature-humidity index. The study was carried out during summer months (June/July) in two free-stall barns located in north-eastern Poland. The buildings for the study were selected based on t...

Considering the rapid climate changes worldwide, with the purpose to reduce financial losses for dairy farmers and enable a more sustainable farming as well, there is an increasing necessity to implement breeding values for heat resistance in breeding strategies. The estimation of breeding values requires a determination of temperature-humidity index (THI) threshold value. Therefore, the object...
