Co-occurring species often have different strategies for tolerating daily cycles of water stress. One underlying parameter that can link together the suite of traits that enables a given strategy is wood density. Here we compare hydraulic traits of two pioneer species from a tropical forest in Panama that differ in...
Plant hydraulic architecture (PHA) has been linked to water transport sufficiency, photosynthetic rates, growth form and attendant carbon allocation. Despite its influence on traits central to conferring an overall competitive advantage in a given environment, few studies have examined whether key aspects of PHA are indicative of successional stage, especially...
The article discusses how to bring the educational benefits that come from analyzing and interpreting physical materials to a bigger class environment and whether these benefits are worth the costs. It notes the growth of literature on instruction in special collections environments and the creative instructional methods presented by its...
We lack a deep understanding of genetic and metabolic attributes specializing in microbial consortia for initial and subsequent waves of colonization of our body habitats. Here we show that phylogenetically interspersed bacteria in Clostridium cluster XIVa, an abundant group of bacteria in the adult human gut also known as the...
Although the regulations are imperfectly enforced, logging firms in the Brazilian Amazon are subject to
forest management regulations intended to reduce environmental damage and protect future forest productivity.
Additionally, voluntary best practices firms adopt to achieve environmental performance that
exceed regulatory requirements are largely limited to reduced impact logging (RIL)...
