Fish biodiversity largely depends on different environmental factors including water quality parameters. The current study was conducted to investigate the impacts of variables fish at upstream and downstream river Meghna in dry rainy season 2011. Twelve samples 66 were collected from 2 sampling stations during period where 61 finfish species 5 shellfish species. number catch both seasons signi...
To understand the genetic variability of the tetraploid fern Ceratopteris thalictroides (Parkeriaceae), we described 30 polymorphic microsatellite markers obtained using the restriction site-associated DNA (RAD) tag sequencing technique. A total of 26 individuals were genotyped for each marker. The number of alleles per locus ranged from 4 to 10, and the expected heterozygosity and the Shannon-...
LDDist is a Perl module implemented in C++ that allows the user to calculate LogDet pair-wise genetic distances for amino acid as well as nucleotide sequence data. It can handle site-to-site rate variation by treating a proportion of the sites as invariant and/or by assigning sites to different, presumably homogenous, rate categories. The rate-class assignments and invariant proportion can be s...
Abstract. We prove Poincaré and Plancherel–Polya inequalities for weighted p-spaces on weighted graphs in which the constants are explicitly expressed in terms of some geometric characteristics of a graph. We use a Poincaré-type inequality to obtain some new relations between geometric and spectral properties of the combinatorial Laplace operator. Several well-known graphs are considered to dem...
The use of remote sensing techniques as a suitable solution to estimate the levels of species diversity is of high importance for the sustainable management of forests. In order to investigate the potential of using sensor data from Landsat 7 ETM+ to estimate species diversity in the Zagros forests, digital data related to the August 7, 2002 from forests in the Qalajeh Kermanshah Province were ...

Anthropogenic Biomes describe globally significant ecological patterns within the terrestrial biosphere caused by sustained direct human interaction with ecosystem, including agriculture, urbanization, forestry and other land uses. The present study focused on the invertebrate diversity in Marudhamalai Hills which is highly disturbed by human activities. Different techniques to identify the dis...
We prove that the exact reconstruction of a function s from its samples s(xi) on any “sufficiently dense” sampling set {xi}i∈Λ can be obtained, as long as s is known to belong to a large class of spline-like spaces in Lp(Rn). Moreover, the reconstruction can be implemented using fast algorithms. Since a limiting case is the space of bandlimited functions, our result generalizes the classical Sh...
Abstract In organic farming the control of perennial weed species, in particular Cirsium arvense , can be a major concern for farmers, especially if there is no regulation through forage production. To test whether stubble cleaner (SC), an enhanced skim plow (PL), as effective C. and other weeds conventional ploughing production, field experiment was established. Three different tillage/crop ro...
We set up a new general coorbit space theory for reproducing representations of a locally compact second countable group G that are not necessarily irreducible nor integrable. Our basic assumption is that the kernel associated with the voice transform belongs to a Fréchet space T of functions on G, which generalizes the classical choice T “ LwpGq. Our basic example is T “ Ş pPp1,`8q L pGq, or a...
