Aim Relationships between range size and species richness are contentious, yet they are key to testing the various hypotheses that attempt to explain latitudinal diversity gradients. Our goal is to utilize the largest data set yet compiled for New World woody plant biogeography to describe and assess these relationships between species richness and range size. Location North and South America. ...

In this article the collection of specimens related to Onosma sulaimanica from Kordestan Province, Iran, was confirmed and reported for the first time. Therefore, the species is recorded for the flora of Iran. This species is placed in the sect. Onosma, subsect. Onosma, ser. Wheeler-hainesii. A diagnostic key of related taxa belonging to series Wheeler-Hainesii and Aleppica, and the photos, mic...

This study was conducted to identify and classify the lichens; determine the diversity index and richness of lichens. A total of 36 species belonging to six genera under three families was identified. Lichen species were mostly found at moderate high altitudinal range with an elevation of 1,131 meters above sea level and open areas where they received adequate sunlight with high moisture and hu...

The paper explores the connection between short-range social ties (i.e. links with close relatives) and the occurrence of suicide. The objective is to discriminate between a model based on social ties and a model based on psychological traumas. Our methodological strategy is to focus on instances characterized by the severance of some social ties. We consider several situations of this kind. (i...

We examined the patterns of composition and structure of parasite communities in the Mediterranean sparid fish Boops boops along a gradient of fish sizes, using a large sample from a single population. We tested the hypothesis that species forming the core of the bogue parasite fauna (i.e. species which have a wide geographical range and are responsible for recognizable community structure) app...

Assisted colonization is a form of conservation translocation which introduces species at risk from extinction to new habitats, beyond their current range, in anticipation of more suitable conditions. Identifying which species, communities and ecosystems may benefit most from assisted colonization in coming decades is a key goal for conservation. Climate change is expected to lead to the loss o...

Home-range size is a key aspect of space-use, and variation in home-range structure may have profound consequences for the potential impact damage control strategies invasive species. However, knowledge on naturalized parrot species very limited. The aim this study was to quantify patterns according sex age monk parakeet Myiopsitta monachus, an Europe. Mean kernel 12.4 ± 1.22 ha (range 1.7–74.1...

This paper reports on three species of mites of the genus Myrmozercon Berlese, 1902 associated with ants in Iran--Myrmozercon crinitus Joharchi sp. nov. from Pheidole pallidula (Nylander), Myrmozercon michaeli Joharchi sp. nov. from Messor sp. and Myrmozercon tauricus Trach & Khaustov from Crematogaster schmidti (Mayr) in the bark of grape vines.
