چکیده

THE CATASTROPHIC GLOBAL IMPACT of rainforest destruction on the species that inhabit tropical areas is now receiving increased attention in the media. In contrast, the slow but inexorable changes in climate that are a by-product of rainforest destruction have only recently entered the limelight. The accumulation of gases in the atmosphere due to the burning of fossil fuels and the reduced photosynthetic potential of a deforested Earth produce climatic effects that are likely to be profound. In two papers that are destined to become citation classicsl,2, Robert Peters of the World Wildlife Fund made the logical connection between the current trends towards a warmer climate and the fact that the present sites of many nature reserves may soon no longer enjoy the meteorological conditions necessary for the well-being of the species they were established to support. A conference convened by the World Wildlife Fund, held in Washington in October 1988, brought together speakers from a variety of different disciplines to discuss the potential consequences for biodiversity of the currently available predictions for climate change. This article complements two other recent reports of the conference3e4.

Biological assessment of the Tang Sorkh River (Iran) using benthic macroinvertebrates

A biological assessment of the Tang Sorkh River (Iran) was studied from July 2013 to August 2014 using benthic macroinvertebrate communities. Samples were gathered every two months, from five stations using a Surber sampler( 30×30cm), fixed in formalin (4%) and then separated and identified in the laboratory. Environmental conditions (current velocity, temperature, depth, width, dissolve oxygen...

Investigation of Genetic Diversity and Relationships Among Agronomic Traits of Some Flax Genotypes

Extended Abstract Introduction and Objective: Flax (Linum usitatissimum L.) from the Linum genus and Linaceae family is one of the oldest oil products in the world. A natural population with sufficient genetic diversity is necessary to select the desired phenotypic traits, so the study of genetic diversity and the correct selection of essential tools is the main breed of plant. Agriculture fac...

Evaluation of the effects of biological operations on functional diversity and soil of carbon stock (Case study: Arange watershed, Alborz province)

 Communities or ecosystems with higher biodiversity also have higher levels of ecosystem function and services, so the relationship between functional diversity and sustainability of plant communities is essential to predict ecosystem functioning. The aim of the present study was to investigate the relationship between carbon stocks and different species diversity and functional indices as well...

بررسی تنـوع ژنتیکی ارقـام و هیبریدهای F1 گندم دوروم با استفاده از صفات زراعی و مورفولوژیک

An experiment was conducted to investigate the genetic diversity in the cultivars and F1 hybrids of durum wheat, using agronomic and morphological traits. Evaluation of consistency between choosing parents of crosses based on morphological and agronomic observations and genetic distance obtained from cluster analysis were objectives of this study. Fourty- two genotypes were evaluated using a ra...
