Advances in linear Algebra & Matrix Theory 2018年第1期8卷 11-17页

作者： Hugo leiva raúl Manzanilla Yachay Tech School of Mathematical Sciences and Information Technology Imbabura Ecuador

In this paper, we study the existence of solutions for the semilinear equation , where A is a , , and is a nonlinear continuous function. Assuming that the Moore-Penrose inverse AT(AAT)-1?exists (A denotes the transposed matrix of A) which is true whenever the determinant of the matrix AAT is different than zero, and the following condition on the nonlinear term satisfied . We prove that the semilinear equation has solutions for all. Moreover, these solutions can be found from the following fixed point relation .

Small mammal community response to early meadow–forest succession

引用

Forest Ecosystems 2017年第3期4卷 211-220页

作者： linas Bal?iauskas Au?ra ?epukien? laima Bal?iauskien? Nature Research Centre

Background： With farmland afforestation becoming common policy in many European Union countries, we studied how early forest succession（from meadow to young stand） influences small mammal species composition, diversity,abundance and biomass. Despite numerous investigations into forest succession, almost no attention has been given to the small mammal community change in the early-successional forest ecosystems, starting with the pre-forest habitat and ending with stand formation and the establishment of tree dominance. We compared small mammal communities in meadows at the initial stage of regrowth（with saplings less than 10 cm in height）, in young forest（5–10 years old） and more advanced forest（15–20 years） in both cases of human-induced forest succession, where the trees had been planted, and natural forest succession, where natural regrowth of meadows had ***： The greatest diversity of small mammal species was recorded in the meadow（H = 2.95）, with a lower diversity found in the young forest（H = 2.61） and even lower in the advanced forest（H = 2.04）, the last habitat being the most monodominantic. The order of species dominance from Microtus sp.（M. arvalis, M. agrestis）, Myodes glareolus, Apodemus flavicollis, Sorex araneus, A. agrarius in the meadow changed to M. glareolus, S. araneus, M. arvalis,M. agrestis in the young forest and to M. glareolus, A. flavicollis, S. araneus in the advanced forest. The lowest relative abundance of small mammals was recorded in the meadow（18.19 ± 2.27 ind. Per 100 trap-days）, with Microtus voles being the most abundant. Relative abundance was higher in the young forest（22.72 ± 2.25 ind. Per 100 trap-days）,with Myodes glareolus being the most abundant（7.59 ± 0.96 ind. Per 100 trap-days） and at its highest in the advanced forest（23.91 ± 2.77 ind. Per 100 trap-days）, again with M. glareolus being the most abundant（15.54 ± 2.35 ind. Per100 trap-days）.Conclusions： Thus, our analysis suggests that that during early meadow-f
