Summary Clusia nanophylla (Clusiaceae), a new tree species from Panama, is described. The species has the smallest leaves recorded so far within the genus. Its staminate flowers have 17 or 18 free stamens and the pistillate flowers present 3 petals, sepals, staminodes, stigmas, styles and carpels. The species is known from one location, and according to IUCN criteria, is here assessed as threatened. Comments on two invalid nam...
Substantial Deep‐Soil Carbon Losses Outweigh Topsoil Gains in European Beech Forests Since the 1980sNARA Subscribed
Soils are a major reservoir for organic carbon (C), with subsoils (> 20–30 cm soil depth) storing most of this C. Predicting the response of deep‐soil C to global change remains a critical research priority; yet long‐term field observations for forests are scarce. In this study, we assessed decadal C dynamics in mineral soils to 90 cm depth of 62 temperate mature stands of European beech ( Fagus sylvatica ) in Austria using da...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
Nutrient acquisition strategies augment growth in tropical N 2 ‐fixing trees in nutrient‐poor soil and under elevated CO 2NARA Subscribed
Tropical forests play a dominant role in the global carbon (C) cycle, and models predict increases in tropical net primary productivity ( NPP ) and C storage in response to rising atmospheric carbon dioxide ( CO 2 ) concentrations. The extent to which increasing CO 2 will enhance NPP depends in part on the availability of nitrogen (N) and phosphorus (P) to support growth. Some tropical trees can potentially overcome nutrient l...
Pollen and stamen mimicry: the alpine flora as a case studyNARA Subscribed
Species‐specific responses to climate change and community composition determine future calcification rates of Florida Keys reefsNARA Subscribed
Anthropogenic climate change compromises reef growth as a result of increasing temperatures and ocean acidification. Scleractinian corals vary in their sensitivity to these variables, suggesting species composition will influence how reef communities respond to future climate change. Because data are lacking for many species, most studies that model future reef growth rely on uniform scleractinian calcification sensitivities t...
No evidence that elevated CO 2 gives tropical lianas an advantage over tropical treesNARA Subscribed
Recent studies indicate that lianas are increasing in size and abundance relative to trees in neotropical forests. As a result, forest dynamics and carbon balance may be altered through liana‐induced suppression of tree growth and increases in tree mortality. Increasing atmospheric CO 2 is hypothesized to be responsible for the increase in neotropical lianas, yet no study has directly compared the relative response of tropical...
Climate warming is expected to increase respiration rates of tropical forest trees and lianas, which may negatively affect the carbon balance of tropical forests. Thermal acclimation could mitigate the expected respiration increase, but the thermal acclimation potential of tropical forests remains largely unknown. In a tropical forest in Panama, we experimentally increased nighttime temperatures of upper canopy leaves of three...
