Tardigrades of Alaska: distribution patterns, diversity and species richness

Emerging patterns of species richness, diversity, population density, and distribution in the skates (Rajidae) of Alaska

Abstrac t —Six years of bottomtrawl survey data, including over 6000 trawls covering over 200 km2 of bottom area throughout Alaska’s subarctic marine waters, were analyzed for patterns in species richness, diversity, density, and distribution of skates. The Bering Sea continental shelf and slope, Aleutian Islands, and Gulf of Alaska regions were stratified by geographic subregion and depth. Spe...

Tardigrades: Species Relationships

Evaluation of species diversity and spatial distribution characteristics of five dominant plant species in Hamoon wetlands

This research aimed to investigate plant species diversity and spatial distribution of five dominant species i.e. Phragmites australis, Tamarix meyeri, Aeluropus littoralis, Aeluropus lagopoides and Cynodon dactylon in Hamoon international wetlands in 2015. To this end, a randomize-systematic sampling method was used according to w pattern by four strip transect at 5000 m2 at each station. The ...

Assessing the accuracy of species distribution models to predict amphibian species richness patterns.

1. Evaluating the distribution of species richness where biodiversity is high but has been insufficiently sampled is not an easy task. Species distribution modelling has become a useful approach for predicting their ranges, based on the relationships between species records and environmental variables. Overlapping predictions of individual distributions could be a useful strategy for obtaining ...

Croatian mayflies (Insecta, Ephemeroptera): species diversity and distribution patterns

Knowledge of the mayfly biodiversity in the Balkan Peninsula is still far from complete. Compared to the neighbouring countries, the mayfly fauna in Croatia is very poorly known. Situated at the crossroads of central and Mediterranean Europe and the Balkan Peninsula, Croatia is divided into two ecoregions: Dinaric western Balkan and Pannonian lowland. Mayflies were sampled between 2003 and 2013...
