Precise information on spatial patterns of species richness and endemic species distribution is important for effective species conservation. In the Caucasus Ecoregion such information is virtually non-existent for invertebrate taxa. Using occurrence data from a large database we calculated species distribution models with the GARP algorithm for 471 spider species to visualize the diversity distribution of spider species in this region. Overall species diversity was highest in mountain forests… Expand

An Inverse Elevational Species Richness Gradient of Caucasian Vascular Plants and Encyrtidae (Hymenoptera, Chalcidoidea)
Contrary to expectation, species richness of both taxa to peak at highest elevations was found and this unusual pattern was related to particular shifts in vegetation types, from relatively species-poor forests over rich grasslands towards poorer highland scrub vegetation. Expand
Geographical patterns of species richness and beta diversity of Larentiinae moths (Lepidoptera: Geometridae) in two temperate biodiversity hotspots
Constant high values of spatial turnover across 17° of latitudinal gradient may indicate that diversity has been formed by a consistent mechanism of horizontal species level diversification of larentine moths throughout mountains. Expand
Patterns of oribatid mite species diversity: testing the effects of elevation, area and sampling effort
The results showed that elevation and area are strongly correlated and both have strong linear effects on species diversity distribution when studied separately and it was suggested that the sampling alone may be responsible for patterns observed and thus should be considered in ecological studies when eligible.

Eukaryotic Communities in Bromeliad Phytotelmata: How Do They Respond to Altitudinal Differences?
The results indicate that differences in height affect diversity patterns of bromeliad phytotelmata communities, which were more diverse at lower altitudes in comparison with more homogeneous communities at higher levels. Expand
Faunal biodiversity research in the Republic of Georgia: a short review of trends, gaps, and needs in the Caucasus biodiversity hotspot
We evaluated progress towards animal biodiversity research in Georgia, a key area in the Caucasus biodiversity hotspot. By reviewing recently (1990–2018) published articles in all areas of animalExpand
Spatial patterns and environmental determinants of community composition of web-building spiders in understory across edges between rubber plantations and forests
Temperature range and average temperature appear to drive the distribution patterns of species diversity and total abundance of spiders in rubber plantations, whereas dry twigs and seedlings probably provide reliable web support and suitable refuges. Expand

We evaluated progress towards animal biodiversity research in Georgia, a key area in the Caucasus biodiversity hotspot. By reviewing recently (1990-2018) published articles in all areas of animalExpand
The Dendroclimatological Potential of Common Yew (Taxus baccata L.) from Southern Azerbaijan
ABSTRACT Paleoclimate reconstructions from tree rings have so far been restricted to the western and northern Caucasus, and there have been no published tree-ring studies on any topic from theExpand


Climate-based model of spatial pattern of the species richness of ants in Georgia
For optimal planning of conservation and monitoring measures, it is important to know the spatial pattern of species richness and especially areas with high species richness. A spatial pattern of theExpand
Using ecological niche modelling to identify diversity hotspots for the herpetofauna of Pacific lowlands and adjacent interior valleys of Mexico
This article documents the conservation status of the herpetofauna in the Pacific lowlands and adjacent Balsas Basin and Chiapas Depression regions and the presents the results of modelling speciesExpand
Climate-based models of spatial patterns of species richness in Egypt’s butterfly and mammal fauna
It is suggested that climate-based models of species richness could provide a rapid method for selecting potential areas for protection and thus have important implications for biodiversity conservation. Expand
Assessing the conservation value of the spider fauna across the West Palearctic area
The conservation index shows that several island territories are of a high conservation interest: the Mediterranean and Atlantic islands clearly exhibit the highest conservation value and some islands can be considered hotspots of biodiversity for the West Palearctic area; other hotspots are some small Mediterranean islands.

Global Patterns of Mammalian Diversity, Endemism, and Endangerment
To assess the conservation status of the world’s land mammals, we compiled data on the number of total species, endemic species, recently extinct species, and currently endangered species for 155Expand
Macroecological patterns of spider species richness across Europe
It is concluded that these first continental wide analyses grasp the overall pattern in spider species richness of Europe quite well, although some of the observed patterns are not directly causal. Expand
Determinants of local spider ( Araneidae and Thomisidae ) species richness on a regional scale: climate and altitude vs. habitat structure
The habitat heterogeneity hypothesis states that the more complex the habitat, the higher the species richness. The present study analyzes the effect of local factors on regional spider ( AraneidaeExpand
Species distribution modelling as a macroecological tool: a case study using New World amphibians
In the face of the high deforestation rates coupled with incomplete data on species distributions, especially in the tropics, SDM represents a useful macroecological tool for investigating broad-scale richness patterns and the dynamics between species richness and climate. Expand
Arthropod Diversity in a Tropical Forest
This work sampled the phylogenetic breadth of arthropod taxa from the soil to the forest canopy in the San Lorenzo forest, Panama using a comprehensive range of structured protocols and found that models based on plant diversity fitted the accumulated species richness of both herbivore and nonherbivore taxa exceptionally well.

Butterfly Species Richness Patterns in Canada: Energy, Heterogeneity, and the Potential Consequences of Climate Change
The butterflies of Canada provide a superb baseline for studying the effects of climate on contemporary patterns of species richness and comprise the only complete pollinator taxon for which this sort of analysis is currently possible. Expand
