Travails of an intrepid platypus counter

For more than a decade, Josh Griffiths has been trapping the elusive venomous mammals to survey the status of their population.
Consequences of vertical basic wood density variation on the estimation of aboveground biomass with terrestrial laser sc...
Stump-to-tip trends in basic wood density complicate the conversion of tree volume into aboveground biomass. We use 3D tree models from terrestrial laser scanning to obtain tree-level volume-weighted wood density.
Terrestrial laser scanning (TLS) is used to generate realistic 3D tree models that enable a non-destructive w...
Unraveling the relative role of light and water competition between lianas and trees in tropical forests : a vegetation ...
...
1. Despite their low contribution to forest carbon stocks, lianas (woody vines) play an important role in the carbon dynamics of tropical forests. As structural parasites, they hinder tree survival, growth and fecundity; hence, they negatively impact net ecosystem productivity and long-term carbon sequestration. 2. Competition (for water and light)...
Evaluating structural and compositional canopy characteristics to predict the light-demand signature of the forest under...

Sixteen hundred years of increasing tree cover prior to modern deforestation in Southern Amazon and Central Brazilian sa...
Tropical ecosystems are under increasing pressure from land-use change and deforestation. Changes in tropical forest cover are expected to affect carbon and water cycling with important implications for climatic stability at global scales. A major roadblock for predicting how tropical deforestation affects climate is the lack of baseline conditions...
Resource allocation in transboundary tuna fisheries: A global analysis.
Resource allocation is a fundamental and challenging component of common pool resource governance, particularly transboundary fisheries. We highlight the growing importance of allocation in fisheries governance, comparing approaches of the five tuna Regional Fisheries Management Organizations (tRFMOs). We find all tRFMOs except one have defined res...
Toxic effects of phenanthrene intensify with an increase of temperature for the populations of a free-living nematode
Phenanthrene is one of the most common Polycyclic Aromatic Hydrocarbons (PAHs) in the marine environment. It has high lipoafinity and environmental persistence and tends to accumulate in benthic ecosystems. Exposure to phenanthrene can have severe impacts on a wide range of marine organisms, from nematodes to fish. These effects can be exacerbated ...
Ecological indicator and traits values for Swedish vascular plants
We introduce and provide a new data-set of species-specific ecological indicator values (alternative 'Ellenberg values' for climatic variables, light, moisture, soil reaction/pH, salinity, nitrogen and phosphorus plus response to management and disturbance), physiological and reproductive traits (including symbionts, phenology, pollinators, nectar ...
Contrasting responses of woody and herbaceous vegetation to altered rainfall characteristics in the Sahel
...
Abstract. Dryland ecosystems are a major source of land cover, account for about 40% of Earth's terrestrial surface and net primary productivity, and house more than 30 % of the human population. These ecosystems are subject to climate extremes (e.g. large-scale droughts and extreme floods) that are projected to increase in frequency and severity u...
Rapid protein evolution, organellar reductions, and invasive intronic elements in the marine aerobic parasite dinoflagel...
...
Dinoflagellates are aquatic protists particularly widespread in the oceans worldwide. Some are responsible for toxic blooms while others live in symbiotic relationships, either as mutualistic symbionts in corals or as parasites infecting other protists and animals. Dinoflagellates harbor atypically large genomes (~ 3 to 250 Gb), with gene organizat...
