Elephant rewilding affects landscape openness and fauna habitat across a 92-year period.

Trophic rewilding aims to promote biodiverse self-sustaining ecosystems through the restoration of ecologically important taxa and the trophic interactions and cascades they propagate. How rewilding effects manifest across broad temporal scales will determine ecosystem states; however, our understanding of post-rewilding dynamics across longer time periods is limited. Here we show that the restoration of a megaherbivore, the African savannah elephant (Loxodonta africana), promotes landscape openness (i.

Spatial geochemistry influences the home range of elephants.

The unique geochemistry surrounding the Palabora Mining Company (PMC) land may act as a micronutrient hotspot, attracting elephants to the area. The PMC produces refined copper and extracts phosphates and other minerals. Understanding the spatial influence of geochemistry on the home range size of African elephants is important for elephant population management and conservation.

Assessment of HIV-intrathecal humoral immune response in AIDS-related neurological disorders.

Intrathecal synthesis of IgG directed to HIV antigens was investigated by antibody specific index (ASI), affinity-mediated immunoblot (AMI) and Western blot (WB) assay in a group of 88 AIDS patients of which 28 with HIV-associated neurological disorders (HAND), 13 without associated neurological disorders (WAND) and 47 with non-HIV-associated neurological disorders (non-HAND). CD4+ count was above 50 cells/mm3 (CD4+>50) in 30 and below 50/mm3 (CD4+<50) in 58 patients, respectively. A significantly higher frequency for CSF complete anti-gag profile (p<0.

Analysis of psychiatric consultations in patients with HIV infection and related syndromes.

Patients referred to the consultation-liaison psychiatry department of the University of Ferrara over a 12 month period were studied. About 13% of referrals concerned HIV patients. Comparison of HIV infected with non-HIV infected referrals revealed differences in the reasons for psychiatric consultation and the diagnosis made after assessment, as well as in the number of follow-up consultations.
