As befitting an evolutionary approach to the study of human behavior, the papers in this special issue of Human Nature cover a diversity of topics in modern and traditional societies. They include the goals of hunting in foraging societies, social bias, cooperative breeding, the impact of war on women, leadership, and social mobility. In combination these contributions demonstrate the utility o...

Human reproductive ecology is a relatively new subfield of human evolutionary biology focusing on the responsiveness of the human reproductive system to ecological variables. Many of the advances in human, and more recently primate, reproductive ecology concern the influence of energetics on the allocation of reproductive effort. This paper reviews eleven working hypotheses that have emerged fr...

Lactobacilli were found in saliva, on teeth, and on the dorsum of the tongue, the vestibular mucosa, and the hard palate in humans. Their proportions in saliva, expressed as percentage of the anaerobically cultivable flora, were 10- to 100-fold higher than those on the tooth surface, but were comparable to those on the epithelial surfaces. The adherence of Lactobacillus casei and L. fermenti to...

Far less is known about viruses inhabiting the human body, but their ecology suggests they may be shared between close contacts. RESULTS Here, we report the ecology of viruses in the guts and mouths of a cohort and demons...

landscape ecology as a modern interdisciplinary science offers new concepts, theories, and methods for land evaluation and management. a main part of landscape ecology is describing patterns in the landscape and interpreting the ecological effects of these patterns on flora, fauna, flow of energy and materials. remote sensing and gis techniques have a high ability for landscape researchers to s...

Journal: :Bulletin of the Ecological Society of America 2021

The Applied Ecology and Human sections of the Ecological Society America (ESA) have collaborated for several years, given their overlapping common interests in human dimensions ecology. Starting 2008, worked together on combined activities at annual meetings, including field trips, BioBlitzes, collaborative workshops, mixers (Fig. 1). While each section has its own mission objectives concerning...
