Amongst many ongoing initiatives to preserve biodiversity, the Millennium Ecosystem Assessment again shows the importance to slow down the loss of biological diversity. However, there is still a gap in the overview of global patterns of species distributions. This paper reviews how remote sensing has been used to assess terrestrial faunal diversity, with emphasis on proxies and methodologies, w...

BACKGROUND The low taxonomic diversity of polar marine faunas today reflects both the failure of clades to colonize or diversify in high latitudes and regional extinctions of once-present clades. However, simple models of polar evolution are made difficult by the strikingly different faunal compositions and community structures of the two poles. METHODOLOGY/PRINCIPAL FINDINGS A comparison of ...

As I write this chapter in mid 2012, the context in which floral and faunal research is done is changing rapidly. Demand for biodiversity information, especially to understand global change, is increasing. The technologies that are available for carrying out biodiversity research and for disseminating the results are changing dramatically. The funding processes and organisational cultures of th...

J. J. Lawler,* A. S. Ruesch, J. D. Olden and B. H. McRae Abstract Historically, many species moved great distances as climates changed. However, modern movements will be limited by the patterns of human-dominated landscapes. Here, we use a combination of projected climate-driven shifts in the distributions of 2903 vertebrate species, estimated current human impacts on the landscape, and movemen...

considering the importance of parasitic wasps in biological control of pests, a faunal study was conducted in the year 2012 on eulophid wasps (hym.: chalcidoidea) in rice fields in the east of guilan province, southern coast of caspian sea. several specimens were captured via malaise traps. the specimens were identified as aprostocetus deobensis (graham), aprostocetus mycerinus (walker), elasmu...

benthic foraminiferal assemblages from maastrichtian strata, gansserina gansseri-abathamphalus mayaroensis planktonic foraminiferal zone, of the abtalkh formation at aitamir section (west of the kopeh-dagh basin) were investigated in order to evaluate the palaeoenvironmental changes (organic matter flux and bottom-water oxygenation). maastrichtian faunal assemblages are well preserved and diver...
