Data from: Grazing-induced shifts in community functional composition and soil nutrient availability in Tibetan alpine meadows

Kechang Niu, Jin-Sheng He & Martin J. Lechowicz
The functional structure of plant communities can be altered by grazing through two main mechanisms: species turnover (i.e. changes in species occurrence and relative abundance) and intraspecific trait variability (ITV), which is driven by phenotypic responses of individual plants and shifts in the relative abundance of genotypic variants within species. Studies of grassland ecosystem function under grazing often focus on community changes induced by species turnover, which ignores the effects of ITV on biomass productivity,...

Data from: Discrimination behavior mediates foraging quality versus quantity trade-offs: nut choice in wild rodents

Discrimination, the ability to distinguish sensory stimuli and respond accordingly, is a critical factor underscoring optimal foraging decisions. Nevertheless, little is known about how mammals discriminate between apparently similar foods of different quality. Here, we compared the foraging behavior of Chinese white-bellied rats, Niviventer confucianus, and Edwards’s long-tailed giant rats, Leopoldamys edwardsi, under natural conditions in the field and in a captive enclosure without predation/competition. We examined the behavioral processes involved in discriminating between sound...

Data from: Detecting copper toxicity in sediments: from the sub-individual level to the population level

Katherine J. Jeppe, Jianghua Yang, Sara M. Long, Melissa E. Carew, Xiaowei Zhang, Vincent Pettigrove & Ary A. Hoffmann
1.Sediments accumulate chemicals that can be toxic to biota and often contribute to aquatic ecosystem decline. Measuring mortality in laboratory-bred organisms is a common way to assess sediment toxicity. However, mortality-based responses of resilient laboratory organisms may not reflect indigenous macroinvertebrate responses, which can be relatively more sensitive to sediment toxicants. A possible solution is to also measure responses at the sub-individual level. 2.Several organism responses to sediment copper toxicity were assessed in a field-based...
