Adverse weather conditions during parental care may have direct consequences for offspring production, but longer-term effects on juvenile and parental survival are less well known. We used long-term data on reproductive output, recruitment, and parental survival in northern wheatears (Oenanthe oenanthe) to investigate the effects of rainfall during parental care on fledging success, recruitmen...

The study focused on the perceptions to climate change among rural farming households in the Niger Delta Area, Nigeria. The basic objective was to determine the rural farming household’s perception to climate change in the Area and the specific objective was to determine the direction of change of the climate change indicators (whether increasing, decreasing or constant). Multistage sampling pr...

Within the last decade the study of phenology has taken on new importance because of its contribution to climate-change research.However, phenology data sets spanningmany years are rare in the tropics,making it difficult to evaluate possible responses of tropical communities to climate change. Here we use two data sets (1970–1983 and 1990–2002) to describe the fruiting patterns of the tropical ...

Impacts of long-term climate shifts on the dynamics of intact communities within species ranges are not well understood. Here, we show that warming and drying of the Southwestern United States over the last 25 years has corresponded to a shift in the species composition of Sonoran Desert winter annuals, paradoxically favoring species that germinate and grow best in cold temperatures. Winter rai...

Understanding how the aboveground net primary production (ANPP) of arid and semiarid ecosystems of the world responds to variations in precipitation is crucial for assessing the impacts of climate change on terrestrial ecosystems. Rain-use efficiency (RUE) is an important measure for acquiring this understanding. However, little is known about the response pattern of RUE for the largest contigu...

The world we live in has witnessed some drastic environmental imbalance in recent times. These imbalances have threatened sustainable developmentwhich is the ultimate goal of man-environment relationship. This paper reviews the causes and effects of climate change on man and his environment with a view to using science education to solve the problems posed by climate change. Literature shows th...

This paper provides a case study in which Indigenous knowledge and traditional stories relating to cloud formation, lightning, wind direction, rains, drought, disaster prediction, response, mitigation, and effects of weather on crops are applied in a contemporary context by the tribal peoples of Rajasthan, India. The state of Rajasthan falls in an area of high climate sensitivity, maximum vulne...

The multiple cropping practice is essential to agriculture because it has been shown to significantly increase the grain yield and promote agricultural economic development. In this study, potential multiple cropping systems in China are calculated based on meteorological observation data by using the Agricultural Ecology Zone (AEZ) model. Following this, the changes in the potential cropping s...

Global warming has been shown to strongly influence inland water systems, producing noticeable increases in water temperatures. Rising temperatures, especially when combined with widespread nutrient pollution, directly favour the growth of toxic cyanobacteria. Climate changes have also altered natural water level fluctuations increasing the probability of extreme events as dry periods followed ...

Extreme climatic events triggered by global climate change are expected to increase significantly hence research into vegetation response is crucial to evaluate environmental risk. Yunnan province, locating in southwest China, experienced an extreme drought event (from autumn of 2009 to spring of 2010), with the lowest percentage rainfall anomaly and the longest non-rain days in the past 50 yea...
