Urban bats show dietary flexibility in aquatic arthropod consumption at urban and rural waterbodies

Wildlife Biology, EarlyView.
Urban waterbodies are critical for biodiversity and provide feeding grounds for insectivorous bats. Yet, how urbanisation affects bats' food choices at urban waterbodies and the role of emergent aquatic arthropods remain poorly understood. We compared the diet of three urban bat species – Vespadelus vulturnus, Chalinolobus gouldii,and Myotis macropus –

Leaf water relations of Eucalyptus globulus ssp. globulus and E. nitens: seasonal, drought and species effects [PDF]

Tree Physiology, 1996
In August 1990, a 2-ha plantation was established in an area where rainfall (about 515 mm year(-1)) was insufficient to meet evaporative demand. On nine occasions between September 1991 and April 1993, pressure-volume curves were constructed for irrigated and rainfed Eucalyptus globulus ssp. globulus Labill. and E.

Increasing susceptibility to priming of soil N mineralisation across a subarctic tundra‐forest ecotone under N fertilisation

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change is driving shrub encroachment and treeline advance in the Arctic, increasing inputs of plant‐derived carbon (C) to soil. These inputs could enhance or reduce microbial decomposition of soil organic matter (SOM) (‘priming’), affecting the soil C balance ...
