in this study an attempt has been made to empirically examine the relationship between biodiversity and economic growth using indicators of species diversity and income per capita as proxies for biodiversity and economic growth, respectively.also the effects of agricultural value added as a percentage of gdp, trade freedom index, exchange rate, population, percantage of land developed for agric...

Studies on biodiversity patterns should optimally relate different scales of temporal community variability to spatial variability. Although is often negligible compared variation, it may still constitute a substantial source overall in stream ecosystems. Boreal streams exhibit seasonally recurring environmental periodicity, which can be expected induce synchronous dynamics abiotic variables am...

this paper discusses the integration of biodiversity concerns with environmental impact assessment (eia) procedures of iran. indeed, it compares and analyses this status in six south asian countries. the analysis was based on the reports available from a number of eia report references to biodiversity, and biodiversity related issues, level and compositional, structure or functional component o...

Stream permanence classifications (i.e., perennial, intermittent, ephemeral) are a primary consideration to determine stream regulatory status in the United States (U.S.) and an important indicator of environmental conditions biodiversity. However, at present, no models or products adequately describe surface water presence for determinations. We modified Thornthwaite monthly balance model (MWB...

Biomonitoring is critical for characterizing and monitoring status, spatial patterns, long-term trends in the ecological condition of freshwater ecosystems. The selection cost-effective bioindicators a step establishing such programs. Key indicator considerations are reliable response to anthropogenic disturbances, high benefit-cost-ratio sensitivity at multiple extents. We evaluated non-linear...

The work is devoted to solving the problem of assessing comparative efficiency several common architectures convolutional neural networks for monitoring birds in a natural environment. was solved by detecting recorded video traps installed on feeders regions Panama different architectures. Then comparison made between recognition quality metrics – IoU and mAP, based values metrics, conclusion a...

Mountain streams provide important habitats for many species, but their faunas are especially vulnerable to climate change because of ectothermic physiologies and movements that are constrained to linear networks that are easily fragmented. Effectively conserving biodiversity in these systems requires accurate downscaling of climatic trends to local habitat conditions, but downscaling is diffic...

The study analyzed agricultural extensification and biodiversity loss in Cross River State, Nigeria. The study used primary data with the aid of a well-structured questionnaire to collect data from one hundred and ten respondents (110) through simple random sampling technique. Data collected were analyzed using descriptive statistics as well as inferential statistics. The results revealed that ...

Renewable energy will potentially make an important contribution towards the dual aims of meeting carbon emission reduction targets and future energy demand. However, some technologies have considerable potential to impact on the biodiversity of the environments in which they are placed. In this study, an assessment was undertaken of the realistic deployment potential of a range of renewable en...
