Data from: Competitive reversal between plant species is driven by species-specific tolerance to flooding stress and nutrient acquisition during early marsh succession
1. Understanding plant species interactions along successional trajectories are critical for managing and restoring ecosystems, as both resource availability and abiotic stresses change over time to affect competitive outcomes and species distributions. Newly created ecosystems experience a succession of plants species and rapid changes in resource availability, which may influence the outcome of biotic interactions. How these biotic interactions vary along abiotic gradients in early successional systems is not well understood. 2. Here, we tested the hypothesis that species-specific tolerances to flooding would influence their relative ability to capture resources (i.e., nutrients) and affect competition intensity between pioneer and secondary successional species in an early successional created tidal marsh. We transplanted a competitively dominant higher marsh species, Spartina patens, across an elevation gradient within and outside of clones of a pioneer stress-tolerant low marsh species, Spartina alterniflora. 3. Within six months, Spartina alterniflora had suppressed the stature and growth of S. patens; however, the magnitude of this competitive effect increased at lower marsh elevations where S. alterniflora was more efficient at capturing available nitrogen (N). In unvegetated areas, where S. patens vigor was high, the amount of available N was approximately 40 times greater than within S. alterniflora clones. 4. Synthesis and applications. Our results demonstrate that competition intensity of the stress-tolerant species over the competitive species depended on relative resource capture in response to abiotic stress. Managing for specific vegetation communities in marsh restoration, therefore, requires insight into these relationships and interactions. Specifically, marsh restoration in high nutrient environments will limit the succession to high density competitive species due to competition with stress-tolerant pioneer species, particularly at lower elevations.

Data from: Nutrient-specific compensation for seasonal cold stress in a free-ranging temperate colobine monkey
1. Homeostatic responses of animals to environmentally-induced changes in nutrient requirements provide a powerful basis for predictive ecological models, and yet such responses are virtually unstudied in the wild. 2. We tested for macronutrient-specific compensatory feeding responses by free-ranging golden snub-nosed monkeys (Rhinopithecus roxellana) inhabiting high altitude temperate forests where they experience a substantial difference in ambient temperature in cold winters vs. warmer springs. The monkeys had free access to natural foods throughout the year, and to ensure that any seasonal differences in nutrient intake were due to homeostatic compensation and not constraints on food availability, we studied the monkeys during periods in which they were provisioned with the same amount of supplementary foods in winter and spring. 3. Thermoregulatory energy costs in winter and spring were calculated using partitional calorimetric estimations of convective and radiative heat loss obtained from thermal imaging of free-ranging monkeys in situ. Daily nutrient intakes were measured using continuous focal follows (average 6.9 h/day) of free-ranging individuals (27 in spring and 28 in winter). 4. We used a nutritional geometry framework to integrate these data and test three predictions: i. In order to remain thermoneutral (balance heat loss with heat expenditure), golden snub-nosed monkeys decrease daily energy consumption during the spring compared to winter, ii. Decreased energy intake is accomplished specifically by reducing intake of the primary energetic nutrients, carbohydrate and lipid, relative to protein, and iii. The seasonal reduction in ingested fat and carbohydrate calories will quantitatively match the reduction in thermoregulatory costs in spring compared with winter. 5. Our results showed that energy intake in spring was reduced to almost half (55%) of that in winter. As predicted, this was achieved by specifically reducing fat and carbohydrate consumption with protein intake unchanged, by a quantity (326 kJ/mbm) that almost exactly matched the seasonal difference in the daily energetic costs of thermoregulation (329 kJ/mbm). 6. This is the first study to test for a match between nutrient-specific homeostatic compensation and environmentally-induced perturbations in nutrient requirements in free-ranging animals, and underpins the potential for the homeostasis framework to provide predictive power to ecological models.
