The bii4africa dataset of faunal and floral population intactness estimates across Africa's major land uses

Sub-Saharan Africa is under-represented in global biodiversity datasets, particularly regarding the impact of land use on species' population abundances. Drawing on recent advances in expert elicitation to ensure data consistency, 200 experts were convened using a modified-Delphi process to estimate 'intactness scores': the remaining proportion of an 'intact' reference population of a species group in a particular land use, on a scale from 0 (no remaining individuals) to 1 (same abundance as the reference) and, in rare cases, to 2 (populations that thrive in human-modified landscapes). The resulting bii4africa dataset contains intactness scores representing terrestrial vertebrates (tetrapods: ±5,400 amphibians, reptiles, birds, mammals) and vascular plants (±45,000 forbs, graminoids, trees, shrubs) in sub-Saharan Africa across the region's major land uses (urban, cropland, rangeland, plantation, protected, etc.) and intensities (e.g., large-scale vs smallholder cropland). This dataset was co-produced as part of the Biodiversity Intactness Index for Africa Project. Additional uses include assessing ecosystem condition; rectifying geographic/taxonomic biases in global biodiversity indicators and maps; and informing the Red List of Ecosystems.

Factors associated with social and behavioral problems among children recently diagnosed with brain tumor

Compared the psychological adjustment of 81 children with brain tumors to that of 31 control children with various malignancies not involving the central nervous system. Both groups exhibited significantly increased frequencies of elevations on one or more age- and gender-corrected Social Competence and Behavior Problems scales of the Child Behavior Checklist (CBCL) relative to normative expectations. Comparison of the Brain Tumor and Cancer Control groups revealed no significant differences on any CBCL scale. Among children diagnosed with brain tumors, stepwise multiple regression analyses revealed that low child IQ, residence in a single-parent family, moderate to severe disfigurement, low SES, tumor location, and severe functional impairment were associated with decreased Social Competence scores. Elevated Behavior Problems scores were associated with younger maternal age at the child's birth, tumor location, and residence in a single-parent family. Results reinforce the need to consider complex relationships between demographic characteristics of the child's family, type of brain damage, and the cosmetic and functional status of the child in determining acute psychological adjustment of brain-damaged children.
