In this study, we found unsporulated coccidia oocysts in passerines from the Nevado de Toluca National Park, Mexico. We captured birds and took samples of their droppings during three field visits. We examined a total of 72 fecal samples and found unsporulated coccidia oocysts in 10 samples from five passerine species: Atlapetes pileatus (3), Cardelina ruber (1), Mniotilta varia (1), Oreothlypi...

Herein, we present a variational model devoted to image classiication coupled with an edge-preserving regularization process. In the last decade, the varia-tional approach has proven its eeciency in the eld of edge-preserving restoration. In this paper, we add a classiication capability which contributes to provide images compound of homogeneous regions with regu-larized boundaries. The soundne...

We identified four diagnostic microsatellite loci that distinguish spotted owls (Strix occidentalis), barred owls (Strix varia), F1 hybrids and backcrosses. Thirty-four out of 52 loci tested (65.4%) successfully amplified, and four of these loci (11.8%) had allele sizes that did not overlap between spotted and barred owls. The probability of correctly identifying a backcross with these four loc...

Many ad hoc networks including military networks have a wide range of deployment densities Further they exhibit mobility patterns that induce continual and rapid density changes for instance due to the con uence and dispersion of troops Most ex isting ad hoc networking protocols tacitly or explicitly ignore density variations In this paper we discuss the performance degradation caused by densit...

This paper reviews the prevailing concept of food and nutrition security and points at needs for concept revisions in order to more comprehensively depict causes and indirect consequences for the food and nutrition insecure, and guide policy actions. The state of realization of food and nutrition security is briefly presented, and the menu of policy actions for enhancing food and nutrition secu...
