Modeling the Effects of Gap Cuts on Stand-Level Resilience in Financial and Carbon Sequestration ContextsNARA Subscribed
Climate change is amplifying disturbances in Central European forests, making resilience a key concept in forest management planning. Yet, the impacts and trade-offs of practices regarded as resilience-enhancing, such as pre-rotation age establishment of young trees in canopy gaps remain insufficiently quantified. Here, we adapt a recent quantification framework, using the post-disturbance recovery time of the present value of...
Purpose To investigate the association between age, physical activity, femoral trochlear cartilage thickness and biomarkers of tissue metabolism in a cross-sectional sample of adult males. This study utilizes several emerging biomarkers that have been associated with early joint degenerative changes; serum COMP (cartilage oligomeric matrix protein), HA (hyaluronan) and lubricin. Methods Eighty-one males (age: mean (range): 43(...
Pantropical variability in tree crown allometryNARA Subscribed
Aim Tree crowns determine light interception, carbon and water exchange. Thus, understanding the factors causing tree crown allometry to vary at the tree and stand level matters greatly for the development of future vegetation modelling and for the calibration of remote sensing products. Nevertheless, we know little about large‐scale variation and determinants in tropical tree crown allometry. In this study, we explored the co...
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...
Persistence of aquatic refugia between flow pulses in a dryland river system(Cooper Creek, Australia)NARA Subscribed
In many dryland rivers with intermittent flow, relatively deep segments of the river channel serve as refugia for aquatic life during protracted intervals between flows. Semipermanent channel segments are known as waterholes in the semiarid Cooper Creek system of western Queensland. Fractional water loss by evaporation was estimated in 15 Cooper waterholes from the increase in conservative ion (Na + and Cl − ) concentrations a...
