Climate science has advanced over decades from an initial focus on the development and use of numerical models of Earth’s climate and compilation of rich networks of observational data, to now being in a position to “detect” and “attribute” specific impacts and events to anthropogenic climate change. Recent analyses have thus established the “fingerprint” of anthropogenic climate change in an i...

Resolving the drivers of hydraulic decline during drought is crucial for understanding drought tolerance in crops and natural ecosystems. In the past 15 years, studies of the decline of leaf hydraulic conductance (Kleaf) have supported a major role in controlling plant drought responses. We analyzed the variation in Kleaf decline with dehydration in a global database of 310 species, providing n...

Rice (Oryza sativa L.) is the most important food crop of the world; but drought stress is a serious limiting factor to rice production and yield stability in rainfed areas. Breeding for drought tolerance is a challenging task because of the complexicity of the component traits, screening technique, environmental factors and their interaction. The major setback in drought tolerance breeding is ...

In this report, we summarize the current status of the Jollyville Plateau salamander (Eurycea tonkawae) drawing upon data gathered from two different survey methods, count surveys and capture-mark-recapture (CMR) surveys. We examined short term trends in count data from 2008-2010 in the context of the 2008-2009 drought at thirteen monitoring sites, and long term trends at eight of those sites f...

Water stress decreases the availability of the gaseous substrate for ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) by decreasing leaf conductance to CO(2). In spite of limiting photosynthetic carbon assimilation, especially in those environments where drought is the predominant factor affecting plant growth and yield, the effects of water deprivation on the mechanisms that control R...

OBJECTIVE To estimate the prevalence of childhood wasting and to investigate the effects of drought and conflict on wasting in crisis-affected areas within Ethiopia. METHODS We searched the Complex Emergency Database for nutrition surveys carried out in Ethiopia over the period 2000-2013. We extracted data on the prevalence of wasting (weight-for-height z-scores below -2) among children aged ...

groundwater drought denotes the condition and hazard during a prolonged meteorological drought when groundwater resources decline and become unavailable or inaccessible for human use. the aim of this study is to identify the influencial factors on groundwater drought in hamadan- bahar watershed,iran, to understand the forcing mechanisms. the standardised precipitation index (spi) has been used ...
