Biodiversity in salt marshes: from the patrimonial value to the ecosystem functioning. The case study of the Mont Saint-Michel bay. [PDF]

, 2003
Until 1979, European salt marshes were known only through the inventories of fauna and especially of flora. On such criteria, the salt marshes of the Mont-Saint-Michel bay (France) were regarded as most significant of the French coasts.

Comparing convolutional neural network and random forest for benthic habitat mapping in Apollo Marine Park

Remote Sensing in Ecology and Conservation, EarlyView.
A comparison of Convolutional Neural Network (CNN) and Random Forest (RF) model predictions of benthic habitats within Apollo Marine Park. The CNN (left) and RF (right) classification maps show the spatial distribution of three habitat types: high energy circalittoral rock with seabed‐covering sponges, low complexity circalittoral rock with non‐crowded

Comparison of soil seed banks of habitats distributed along an altitudinal gradient in northern Iran

, 2013
International audienceIn this study we investigated the variations in soil seed banks along an altitudinal gradient in the Alborz mountains, Iran, covering three habitats from lower to upper altitudes: forest, forest-subalpine grassland ecotone and ...

Assessing habitat suitability for black grouse broods at the bioregional scale

Wildlife Biology, EarlyView.
The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

THE MORPHOMETRIC STRUCTURE OF THE LARIX GMELLINII RECRUITMENT AT THE NORTHERN LIMIT OF ITS RANGE IN THE FOREST-TUNDRA ECOTONE

Geography, Environment, Sustainability, 2013
The goal of the research presented herein is the investigation of the morphometric and age parameters of the recruitment of forest stands formed by Larix gmellinii, as an indicator of trends in the dynamics of the northern/upper forest boundary in the ...

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Spatial Distribution of Egg Clusters of the European Pine Sawfly \u3ci\u3eNeodiprion Sertifer\u3c/i\u3e (Geoff.) in Young Pine Plantations in Michigan [PDF]

, 2017
(excerpt) The European pine sawfly, Neodiprion sertifer (Geoffroy), is a perennial problem in young pine plantations in Eastern North America. Scotch pine, Pinus sylvestris L., and red pine, P. resinom Ait., are its principal hosts.

To converge or diverge? Phenological shifts driven by plant genome size and functional traits under nitrogen deposition and mowing

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Linkages between genome size (GS) and phenology underscore the diversification of functional traits, which are indicative of life‐history and resource acquisition strategies.

Seasonal nitrogen enrichment alters plant community stability–area relationship through decreased biodiversity, species asynchrony, and population stability

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Atmospheric nitrogen (N) deposition generally reduces the temporal stability of plant communities (community stability). The positive community stability–area relationship (CSAR) has been reported, but the effects of N deposition on CSAR are unexplored, particularly ...
