Close range hyperspectral camera dataset with high temporal resolution of strawberry with eco-physiological data of one leaf
<p>This high temporal resolution dataset of a strawberry plant was captured in two experiments, each lasting 100h. On leaf was inserted into a leaf chamber of the LI-6400XT gas exchange system, capturing information on transpiration, photosynthesis and stomatal conductance. Environmental characteristics are also captured at canopy height. These experiments were conducted in a growth chamber at ILVO (Melle, Belgium) and only covered conditions that did not result in stress in the plant. As such, this dataset attempts to capture subtle dynamic variation in the plant.</p>

Three eco-physiological strategies of response to drought maintain the form and function of a tropical montane grassland
<p>1. Ecologists seek a general scheme to classify the diversity of plant responses to environmental factors into a few strategies (e.g. competitor -C, stress-tolerant -S, ruderal-R), while plant physiologists seek a mechanistic scheme to explain such different responses (e.g. tolerance, escape, avoidance). So far, few attempts have been made to combine both perspectives into plant eco-physiological strategies. Moreover, the relative contribution of different strategies to maintain both community structure and ecosystem functioning during drought has rarely been assessed. This limits our capacity to predict how extreme events caused by climate change will affect plant communities.</p> <p>2. Here, we present an integrated framework to identify plant eco-physiological strategies and to estimate their contribution to community originality (diversity of trait-combinations), dominance (species relative frequency), and ecosystem functioning (productivity and evapotranspiration).</p> <p>3. We applied this framework in a tropical montane grassland and found three co-occurring eco-physiological strategies in this community (S-tolerance/avoidance, CS-escape/tolerance and CR-escape/avoidance). While CS-species contributed more to dominance and functionality, CR- and S-species contributed more to originality. Therefore, all three strategies were important to support the grassland form and function.</p> <p><i>Synthesis</i>: Plants exhibit different strategies, as well as different contributions to community and ecosystem attributes. We developed an integrated approach to both identify strategies and estimate their relative contribution. Thereby, as droughts intensify, we can better predict which plants are more likely to be lost and how their loss will impact the communities and ecosystem where they occur. This knowledge is necessary for specifying conservation priorities and for developing more efficient conservation practices.</p>
Data from: Life on the edge: a comparative study of eco-physiological adaptations of frogs to tropical semiarid environments
A key goal of ecology and evolution is to understand the relative contributions of environment and history in determining the geographic distribution of organisms. For the Neotropical lowlands, where temperatures are similar across landscapes, we hypothesize that water balance may be a critical but understudied factor in determining the distribution of species. Amphibians are especially sensitive to variation in precipitation due to their permeable skin. Here we focused on lowland frogs of north-western South America and investigated variation among 17 species in potentially important ecologically relevant performance variables related to water balance, and tested for possible adaptations to semiarid conditions within species. We studied frogs from coastal xeric, savannah and wet forest biomes under common laboratory conditions and quantified rates of evaporative water loss, rates of water uptake, and variation in water-searching behavior and performance. We found significant differences in all three performance variables among species, even after accounting for shared evolutionary history. A phylogenetic ANCOVA showed that categorizing species by ecological habits (terrestrial vs. arboreal) explained much of the eco-performance trait variation among species. Secondarily, environment explained additional variation, e.g., coastal xeric species showed reduced rates of water loss and terrestrial savannah amphibians showed lower rates of water uptake. Conspecific frog populations from different biomes exhibited similar performance. We compare our results with previous studies and conclude that ecological habit is the principle factor that predicts eco-physiological trait variation and the possible geographic distribution of lowland Neotropical frogs.

Data from: The 'golden kelp' Laminaria ochroleuca under global change: integrating multiple eco-physiological responses with species distribution models
1. The loss of marine foundation species, in particular kelps at temperate latitudes, has been linked to climatic drivers and co-occurring human perturbations. Ocean temperature and nutrients typically co-vary over local and regional scales and play a crucial role on kelp dynamics. Examining their independent and interactive effects on kelp physiological performance is essential to understand and predict patterns of kelp distribution, particularly under scenarios of global change. 2. Crossed combinations of ocean temperatures and availability of nutrients were experimentally tested on juveniles of the 'golden kelp', Laminaria ochroleuca, from the northwestern Iberian Peninsula. Eco-physiological responses included: survival, growth and total N content. Results were embedded into a Species Distribution Model (SDM), which relates presence records and climatic and non-climatic data to forecast distribution patterns of L. ochroleuca under different climate change scenarios. 3. Temperatures above 24.6 ºC were lethal irrespective of nutrients. Optimal growth of juvenile sporophytes occurred between 12 °C and 18 ºC and no nutrient limitation. The SDM, where ocean temperature was the main predictor of kelp distribution in line with temperature thresholds given by eco-physiological responses, suggests a future expansion towards northern latitudes and a retreat from the southern limit/boundary of the current distribution. 4. Synthesis. Range-shifting of the golden kelp can have severe ecological impacts at regional and local scales. The expansion or retraction of the species along the European coast seems to be modulated mainly by temperature, but nutrient availability would be key to maintain optimal physiological performance. Our work highlights that the combination of empirical and modelling approaches is accessible to researchers and crucial to build more robust predictions of ecological and biogeographic responses of habitat-forming species to forecasted environmental change.
