Noticeable variation was observed in a number of morphological characters in the Glycyrrhiza specimens in various habitats in north of Iran. To study these variations, two taxa related to the Hyrcanian region from all four known taxa of this genus in Iran, including Glycyrrhiza echinata, and G. glabra var. glabra were studied by numerical taxonomy using morphological characters in three provinc...

Temporal and geographic variability in adult body size can be a useful indicator of a population's adaptation. The southern African Cape supported foraging populations exclusively until some pastoralism is seen, ca. 2000 BP. This paper describes and interprets body-size patterns among foragers, as deduced from maximum femoral lengths and femoral head diameters, using 127 individually dated adul...

Aim: Tsetse-transmitted animal and human trypanosomosis is considered to be one of the major constraints to improved livestock and agricultural production in sub-Saharan Africa. A cross sectional survey to determine the prevalence of trypanosomosis and identifying trypanosome species infecting cattle was conducted in Makuyuni division, Arusha region of northern Tanzania, an area where livestock...

The objective of this study is to develop models based on both optical and L-band Synthetic Aperture Radar (SAR) data for above ground dry biomass (hereafter AGB) estimation in mountain forests. We chose the site of the Loveh forest, a part of the Hyrcanian forest for which previous attempts to estimate AGB have proven difficult. Uncorrected ETM+ data allow a relatively poor AGB estimation, bec...

The patterns of diversity Lepidoptera and its relationship with environmental characteristics in the Hyrcanian forests northern Iran have not been investigated so far, while such studies are extremely effective restoring forest biodiversity. This study aimed to assess relationships between vegetation abundance Darabkola forest, Sari district (Mazandaran province, Iran). Light trapping yielded a...

Lakes worldwide are under threat by a myriad of environmental stressors that have been increasing in number and magnitude. These can be regional such as climate change, or local nutrient-rich runoff, invasive species, road salt contamination, to name but few. To protect lake ecosystems from further deterioration, we need long-term data define pre-disturbance baselines identify causing the great...
