International Journal of Osteoarchaeology, EarlyView.ABSTRACT Prior research has documented treponematosis at a single site in Mainland Southeast Asia from northern Vietnam dated to the early agricultural transition (~4000–3500 bp). To date, no other cases in Southeast Asia's prehistory have been identified.

Oikos, EarlyView.Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

Oikos, EarlyView.Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

Overexploitation can counteract top‐down control and the paradox of enrichment in simple food chains
Oikos, EarlyView.Because of its high abundance or its high feeding intensity, a consumer can overexploit its resource by consuming it on a shorter timescale than resource regeneration. While this short‐term overexploitation is widespread in nature, its general implications for biotic control patterns and ecosystem stability are not clear.

Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes
Oikos, EarlyView.Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.

Aromatic plants, nest bacterial diversity, and nestling condition in Corsican blue tits
Oikos, EarlyView.According to the ‘nest protection hypothesis', some passerines incorporate fresh aromatic plants into their nests which reduce pathogens that can negatively affect nestlings. We experimentally evaluated the effect of five aromatic plant species on the nest bacterial microbiota of Corsican blue tits Cyanistes caeruleus.
