Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions
Archaeometry, EarlyView.ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

How Male‐Dominated Teams Deter Men's Contributions to Collective Creative Dynamics and Performance
Creativity and Innovation Management, EarlyView.ABSTRACT Creativity has become increasingly critical for decision‐making, particularly at upper organisational levels where male‐dominated teams remain prevalent. While a substantial body of research has examined the relationship between gender diversity and collective creativity, far less attention has been paid to numerical gender dominance in ...

BiologyAlfalfa (Medicago sativa) is an important fodder crop with 16–25% protein and 20–30% fibre content. It requires pollinators for seed development through a process known as “tripping”. Honey bees are preferred for their easy management and mass rearing to

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Proximity to Woodland and Landscape Structure Drive Pollinator Visitation in Apple Orchard Ecosystem
Frontiers in Ecology and Evolution, 2016 Landscapes of farms and adjacent areas are known to influence abundance of various arthropods such as pollinators in commercial agricultural ecosystems.

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems
Entomologia Experimentalis et Applicata, EarlyView.We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

The steady-state form of large-amplitude internal solitary waves [PDF]
, 2010 A new numerical scheme for obtaining the steady-state form of an internal solitary wave of large amplitude is presented. A stratified inviscid two-dimensional fluid under the Boussinesq approximation flowing between horizontal rigid boundaries is ...

Peptidomic analysis of the venom of the solitary bee Xylocopa appendiculata circumvolans
Journal of Venomous Animals and Toxins including Tropical Diseases, 2017 Background Among the hymenopteran insect venoms, those from social wasps and bees – such as honeybee, hornets and paper wasps – have been well documented.

Ecological Entomology, EarlyView.Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.
