Variation in leaf temperatures of tropical and subtropical trees are related to leaf thermoregulatory traits and not geographic distributions dataset
<p>To predict the effects of global warming on plants, previous studies have investigated how the distributions and physiological performances of plants relate to environmental temperatures. This approach implicitly assumes that leaf temperatures are tightly linked with regional air temperatures. However, the thermoregulatory behaviors and physical properties of leaves can differ greatly between species, leading to different plants having different leaf temperatures even when occurring under similar conditions. It is important to understand this variation in leaf thermoregulatory traits and temperatures in order to predict how individual species will be impacted by global warming. We measured the thermal properties of leaves from >50 tropical and subtropical tree species grown at the Gifford Arboretum (Florida, USA). For each species we measured maximum leaf temperature and rate of leaf warming using a new standardized protocol to control for both environmental variation and select plant thermoregulatory behaviors. We tested the relationships between the thermal variables and several leaf functional traits. Even under laboratory-controlled conditions, leaf temperatures varied by over 8.5<sup>o</sup>C amongst species. Maximum leaf temperature was positively correlated with leaf area and rate of leaf warming was negatively correlated with water content per leaf area. This suggests that some species may be able to offset rising air temperatures through acclimation or adaptation of leaf properties. Next, we tested the relationships between the species' leaf thermal properties and their climatic niches/distributions, but we found no significant associations. These results call into question the use of regional air temperatures to model plant physiological and demographic performance.</p>
Dataset for: Spatial and environmental effects on Coho Salmon life-history trait variation
<p>Adult size, egg mass, fecundity and mass of gonads are affected by trade-offs between reproductive investment and environmental conditions shaping the evolution of life-history traits among populations for widely distributed species. Coho salmon <i>Oncorhynchus kisutch</i> have a large geographic distribution and different environmental conditions are experienced by populations throughout their range. We examined the effect of environmental variables on female size, egg size, fecundity, and reproductive investment of populations of Coho Salmon from across British Columbia using an information theoretic approach. Female size increased with latitude and decreased with migration distance from the ocean to spawning locations. Egg size decreased with average intragravel temperature during incubation, migration distance, in larger rivers, but increased in rivers that were lake headed. Fecundity increased with latitude, warmer temperature during the spawning period, and river size, but decreased in rivers that were lake headed compared to rivers with tributary sources. Gonadal somatic index increased with latitude and decreased with migration distance. Latitude of spawning grounds, migratory distance and temperatures experienced by a population, but also hydrologic features – river size and headwater source – are influential in shaping patterns of reproductive investment, particularly egg size. The lack of an effect of latitude on egg size suggest that local optima for egg size may drive the positive relationship between egg number and latitude – a pattern that is partially off-set by larger female size and gonadal somatic index with latitude.</p>

ArchiWood: dataset of legacy documents about wood anatomical, morphological, and architectural traits for plant species in Madagascar
<p><strong>Abstract</strong></p> <p>Digitization of a part of CIRAD's' xylotheque, one of the most important collections of tropical timber in the world, now allows researchers, experts in the field, trainers and archaeologists to have a new source of homogenized information. This corpus constitutes a unique database on the botanical characteristics of many species of Madagascar and could feed the research in both ecological and systematic fields by the possibility to define traits and criteria usable for example in phylogeny or functional ecology.</p> <p>The island of Madagascar presents a remarkable floristic diversity, with a very high rate of endemism, making it a permanent laboratory for the study of the mechanisms governing evolution.</p> <p>The digitization project was conducted in close coordination with other projects currently underway involving the same partners. 995 species are concerned by the ArchiWood project: 3 planes of anatomical sections for each species, associated with a total of 100 field notebooks (architectural sketches) and 20,000 slides.</p> <p><strong>Contents</strong></p> <p>This dataset is composed of digitized legacy documents, all related to Madagascar biodiversity:</p> <ul> <li>More than 2,300 illustrations and notes taken from field notebooks</li> <li>More than 1,200 anatomical cuts</li> <li>More than 70 photographs of plants and landscapes</li> </ul> <p><strong>Methods</strong></p> <p><em>Digitization of anatomical cuts</em><br> For each species, there are 3 anatomical cuts associated with the 3 planes of symmetry of the material: radial, tangential and longitudinal. Each cut was scanned using an Olympus DP71 digital camera fitted on an Olympus BX60 microscope. The shooting software that drives the camera is Archimed from Microvision Instruments. The image format is 24 bits colored TIFF. Each image is 1600 x 1200 pixels for 3 different magnifications of the microscope: x40 (overview of the cut), x200 (main features anatomical from IAWA), x400 (highlighting fine lines such as punctuations).</p> <p><em>Digitization of sketches (from field notebooks) </em><br> The digitized information in the field notebooks is made up of architectural sketches (with descriptive notes). The slides include additional remarkable visual information of field sketches (flowers, fruits, overview, geographical implantation conditions…). The sketches were scanned using a resolution of 300 dpi, 24 bits colors in JPEG format.</p> <p><em>Digitization of photographs (24 x 36 mm)</em><br> The photographs were scanned at 600 dpi, 24 bits colors in JPEG format.</p> <p><strong>File management and data quality control</strong></p> <p>Controlling images and adding metadata operations were carried out by the researchers concerned in their field of activity (anatomy, botany, architecture). The homogenization and final harmonization of the metadata and data was carried out by the data manager.<br> </p>
