The study of plant under environmental conditions leads to an appreciation of their physical and chemical requirements for growth and reproduction. It contributes to increase the knowledge of where the plants grow. This study was conducted to determine the main autecological characteristics of Salvia hydrangea L. which is an endemic plant distributed in Mazanadarn province, Iran. The habitats o...

The health and functioning of soil ecosystems are the foundation sustainable food production land management. Of key importance in achieving sustainability, is frequent measurement health, indices based on community structure nematodes amongst most widely used toolsets by ecologists. Thirty years after development Maturity Index, we aimed to evaluate application, utility, future directions nema...

The Chilean fjord region includes many remote and poorly known areas where management plans for the marine living resources conservation strategies are urgently needed. Few data available about spatial distribution of its invertebrate fauna, prevalently influenced by complex interactions between biotic abiotic factors, animal behavior human activities. Patagonian fjords a hotspot finfish aquacu...

studying the autecology of range plants provides the basic information on their ecological requirements, cultivation methods and the interactions with the prevailing environment. such information is necessary for a proper range management. some ecological characteristics of astragalus arpilobus kar. & kir., were studied in the winter rangelands of northern khorasan province. it was naturally gr...

Giant clams, the largest living bivalves, live in close association with coral reefs throughout the Indo-Pacific. These iconic invertebrates perform numerous important ecological roles as well as serve as flagship species-drawing attention to the ongoing destruction of coral reefs and their associated biodiversity. To date, no review of giant clams has focussed on their behaviour, yet this comp...

Key aspects of the morphology, autecology, systematics and taphonomy of the crustacean syncarids from the Montceau Lagerstätte (Upper Carboniferous, Stephanian B; France) are presented. Palaeocaris secretanae is the most abundant faunal element of the Montceau biota and shows striking morphological similarities with Palaeocaris typus from the Mazon Creek Lagerstätte (Westphalian D; Illinois, US...
