Mixed‐species social aggregations in Madagascan tadpoles—determinants and species composition [PDF]

Journal of Natural History, 2007
The frequency, species composition, and determinants of mixed‐species tadpole aggregations were analysed under natural conditions in a dry forest of western Madagascar. Most aggregations (73%) were formed by more than one species, with up to four species per individual aggregation.

Feed Conversion, Survival and Development, and Composition of Four Insect Species on Diets Composed of Food By-Products

PLoS ONE, 2015
A large part of the environmental impact of animal production systems is due to the production of feed. Insects are suggested to efficiently convert feed to body mass and might therefore form a more sustainable food and/or feed source.

Prediction of Macronutrients at the Canopy Level Using Spaceborne Imaging Spectroscopy and LiDAR Data in a Mixedwood Boreal Forest

Remote Sensing, 2015
Information on foliar macronutrients is required in order to understand plant physiological and ecosystem processes such as photosynthesis, nutrient cycling, respiration and cell wall formation. The ability to measure, model and map foliar macronutrients

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Patterns of Elevation Gradients in Plant Composition and Diversity of Pinus pumila Communities in Zalinkur Mountain

Diversity
(1) Studying changes in plant composition and diversity of Pinus pumila communities along the elevation is significant for biodiversity conservation; (2) In this study, we systematically analysed Pinus pumila communities’ species composition and ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Disturbances shape the tree community in Ghana's Mole National Park

Journal of Ecology and Environment
Background: The ability of protected areas worldwide to sustain biodiversity is often severely limited due to their vulnerability to persistent and intense disturbance-related drivers, such as agricultural expansion and the exploitation of ecosystem ...
