Salt in the Wound: Trophic Mismatches Emerge Between Macroinvertebrate Secondary Production and Basal Food Resources Along a Salinity Gradient in Central Appalachian Headwaters
… SC levels (250-500 μS/cm) from enriched food resources and an osmo- and iono-physiological optimum before declining from salt-induced stress in streams with higher SC levels. Additionally, I expected that some shredding and detritivore taxa would increase continuously with increasing SC …

Influence of seasonal drought on body condition and nutritional state in selected tropical birds
… across a suite of understory species. Changes in food-resource availability during seasonal drought is one possible mechanism driving the population level responses to dry season length in tropical birds. This project coincided with an extreme El Niño induced drought in central Panama, which …

The value of animal behaviour as a bio-indicator of restoration quality
… assembly was surveyed as a measure of food resource availability. There was a significant difference between woodland and heathland areas and to a lesser, but still significant, extent between restored woodland areas of different ages and remnant woodland. A major finding of this study …
