Does the matrix matter? A forest primate in a complex agricultural landscape
Many threatened primates now exist in fragmented forest habitats. The survival of these populations may depend on their ability to utilise agricultural or other matrix habitats between forest fragments, but this is poorly known. Here, we systematically investigate an arboreal primate’s use of a heterogeneous matrix in a fragmented forest landscape: the Angola black-and-white colobus (Colobus an...
متن کاملdeterminant of the hankel matrix with binomial entries
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.

The Laplacian matrix of a graph G is L(G) = D(G)−A(G), where A(G) is the adjacency matrix and D(G) is the diagonal matrix of vertex degrees. According to the Matrix-Tree Theorem, the number of spanning trees in G is equal to any cofactor of an entry of L(G). A rooted forest is a union of disjoint rooted trees. We consider the matrix W (G) = I + L(G) and prove that the (i, j)-cofactor of W (G) i...
متن کاملLandscape matrix and species traits mediate responses of Neotropical resident birds to forest fragmentation in Jamaica
Land cover and land use surrounding fragmented habitat can greatly impact species persistence by altering resource availability, edge effects, or the movement of individuals throughout a landscape. Despite the potential importance of the landscape matrix, ecologists still have limited understanding of the relative effects of different types of land cover and land uses on species patterns and pr...
متن کاملFragmentation of extracellular matrix by hypochlorous acid.
The interaction of extracellular matrix with cells regulates their adhesion, migration and proliferation, and it is believed that damage to vascular matrix components is a factor in the development of atherosclerosis. Evidence has been provided for a role for the haem enzyme MPO (myeloperoxidase), released by activated monocytes (and possibly macrophages), in oxidative events within the artery ...
