A Ground-Nesting Galliform’s Response to Thermal Heterogeneity: Implications for Ground-Dwelling Birds

The habitat selection choices that individuals make in response to thermal environments influence both survival and reproduction. Importantly, the way that organisms behaviorally respond to thermal environments depends on the availability and juxtaposition of sites affording tolerable or preferred microclimates. Although, ground nesting birds are especially susceptible to heat extremes across m...

Patches of Bare Ground as a Staple Commodity for Declining Ground-Foraging Insectivorous Farmland Birds

Conceived to combat widescale biodiversity erosion in farmland, agri-environment schemes have largely failed to deliver their promises despite massive financial support. While several common species have shown to react positively to existing measures, rare species have continued to decline in most European countries. Of particular concern is the status of insectivorous farmland birds that forag...

Cloud-to-ground Lightning and Urban Areas

The effect of small urban areas on cloud-to-ground (CG) lightning activity is analysed for Spain. The results shown that the CG-flash number is enhanced within and downwind the most of towns considered and that large population and higher SO2 concentration contribute to the increase of the number of CG-flashes. INTRODUCTION AND DATA Several studies have reported that large cities of the USA are...
