Long postmenopausal lifespans distinguish humans from all other primates. This pattern may have evolved with mother-child food sharing, a practice that allowed aging females to enhance their daughters' fertility, thereby increasing selection against senescence. Combined Charnov's dimensionless assembly rules for mammalian life histories, this hypothesis also accounts our late maturity, small size at weaning, and high fertility. It has implications past human habitat choice social...
Extended provisioning of offspring and long postmenopausal life spans are characteristic all modern humans but no other primates. These traits may have evolved in tandem. Analysis relationships between women's time allocation children's nutritional welfare among the Hadza northern Tanzania yields results consistent with this proposition. Implications for current thought about evolution hominid food sharing, history, social organization discussed.
The assumption that large mamm al hunting and scavenging are economically advantageous to hominid foragers is examined in the light of data collected among Hadza northern Tanzania. hunters disregard small prey favour larger forms (mean adult mass ≥ 40 kg). Here we report experimental showing would reduce their mean rates if they included animals array target. Still, daily variance animal returns high, risk failure correspondingly great, significantly greater than associated with game...
Agriculture is expanding rapidly in the miombo woodlands of sub-Saharan Africa. Clear felling results loss species and ecosystem services. The remaining woodland used as a vital support system for farming communities, impact this utilisation on biodiversity service provision not clear. Understanding these effects will aid development effective, sustainable land management strategies multiple outcomes, including conservation resource utilisation. This study provides new data tree diversity,...
According to historical records of transatlantic slavery, traders forcibly deported an estimated 12.5 million people from ports along the Atlantic coastline Africa between 16th and 19th centuries, with global impacts reaching present day, more than a century half after slavery's abolition. Such have fueled broad understanding forced migration Americas yet remain underexplored in concert genetic data. Here, we analyzed genotype array data 50,281 research participants, which—combined shipping...
Hadza hunter-gatherers display economic and social features usually assumed to indicate the dependence of wives children on provisioning husbands fathers. The better hunters have been found be better-nourished, consistent with assumption that men hunt provision their families. Yet, as is common among foragers, share meat widely. Analyses meat-sharing data confirm little from large prey went own household. These analyses also show neither a mans hunting success nor time he spent made any...
Coastal dunes are considered some of the most threatened and vulnerable habitats in European Union. Mapping spatial distribution these is an essential task for their conservation. Advances Unoccupied Aerial Vehicles (UAVs) facilitate flexible acquisition high-resolution imagery identifying detailed distributions within dune systems. This study aimed to assess effectiveness UAV remote sensing mapping habitat types. Specifically, we determined impact temporally acquired UAV-derived spectral...
Natural and semi-natural habitats in agricultural landscapes are likely to come under increasing pressure with the global population set exceed 9 billion by 2050. These non-cropped primarily made up of trees, hedgerows grassy margins their amount, quality spatial configuration can have strong implications for delivery sustainability various ecosystem services. In this study high resolution (0.5 m) colour infrared aerial photography (CIR) was used object based image analysis classification...
Detailed maps of vegetation facilitate spatial conservation planning. Such information can be difficult to map from remotely sensed data with the detail (thematic resolution) required for ecological applications. For grass-dominated habitats in South-East UK, it was evaluated which following choices improved classification accuracies at various thematic resolutions: 1) Hyperspectral versus a reduced spectral resolution eight and 13 bands, were simulated hyperspectral data. 2) A system using...
The increasing need for high quality Habitat/Land-Cover (H/LC) maps has triggered considerable research into novel machine-learning based classification models. In many cases, H/LC classes follow pre‐defined hierarchical schemes (e.g., CORINE), in which fine categories are thematically nested within more general categories. However, none of the existing algorithms account this pre-defined structure. Here we introduce a Random Forest (RF) application classification, fits separate local model...
Radiometric normalization is a vital stage in any change detection study due to the complex interactions of radiance and irradiance between Earth's surface atmosphere. Compensation for variables such as sun's angle, profile, atmospheric conditions, sensor calibration coefficients are essential achieving radiometrically stable data base multi-temporal, multi-spectral imagery study. In this study, five Landsat Enhanced Thematic Mapper Plus (ETM+) images taken over east coast Ireland 2001 were...
Abstract Upland habitats provide vital ecological services, yet they are highly threatened by natural and anthropogenic stressors. Monitoring these vulnerable is fundamental for conservation involves determining information about their spatial locations conditions. Remote sensing has evolved as a promising tool to map the distribution of upland in space time. However, resolutions most freely available satellite images (e.g., 10-m resolution Sentinel-2) may not be sufficient mapping...
