Background & Aim: Different species from mint family (Lamiaceae) are used as spices and fragrance in food or as medicine against viral or microbial diseases in many countries for generation. Lamiaceae family contains 46 genus and 410 species. One of the valuable and medicinal species of this family is Ziziphora clinopodioides Lam. This species contains the essential o...
Woody plant expansions are altering ecosystem structure and function, as well fire regimes, around the globe. Tree-reduction treatments widely implemented in expanding woodlands to reduce fuel loads, increase ecological resilience, improve habitat, but few studies have measured treatment outcomes over long timescales or large geographic areas. The Sagebrush Treatment Evaluation Project (SageSTE...
Benthic invertebrates are a well-established target in environmental quality status evaluations. The AMBI (AZTI's Marine Biotic Index) was developed to determine the impacts and the quality status of soft-bottom marine benthic communities. The aim of this study was investigating multivariate pattern of benthic invertebrate community and application of AMBI (AZTI's Marine Biotic Index) for...
The spectrum of insecticidal activity of Cry51Aa2.834_16 protein targeting hemipteran and thysanopteran insect pests in cotton was characterized by selecting and screening multiple pest and non-pest species, based on representation of ecological functional groups, taxonomic relatedness (e.g. relationship to species where activity was observed), and availability for effective testing. Seven inve...
The study aimed to estimate the effect of ecological factors such as day and night on catch species composition in fishing landings in the perisan Gulf in May 2016. In this study, were catched about 34937.18 kg marine speceis and identified of 64 groups of species and family including 56 groups of bonyfishes, 6 groups of invertabrate, 2 groups of cartilage fishes. Meanwhile, the Bushehr, Hormoz...
The Stenocereus griseus species complex (SGSC) has long been considered taxonomically challenging because the number of taxa belonging to the complex and their geographical boundaries remain poorly understood. Bayesian clustering and genetic distance-based methods were used based on nine microsatellite loci in 377 individuals of three main putative species of the complex. The resulting genetic ...
Connectivity of urban green patches is an important structural attribute of urban landscape that facilitates the species movement and transfer of their genes among their habitats. So far, several methods including Graph Theory have been applied to assess ecological connectivity. This research was aimed to study the application of graph theory to measure the connectivity of green patches in the...
Investigation of ecological, hydrological status and habitat Suitability of river is one of the key elements in river ecosystem management. In this regard, in the present study, in order to evaluate the ecological sustainable conditions in Zarrin-Gol River of Golestan Province, during stepwise calculations, echo-hydraulic and hydromorphocological analysis of the habitat of Capoeta gracilis (Ke...
Eusocial societies present a Darwinian paradox, yet they have evolved independently in insects, mole-rats and symbiotic shrimp. Historically, eusociality has been thought to arise as a response to ecological challenges, mediated by kin selection, but the role of kin selection has recently been questioned. Here we use phylogenetically independent contrasts to test the association of eusociality ...
