Baseline and Stress-Induced Plasma Corticosterone during Long-Distance Migration in the Bar-Tailed Godwit, Limosa lapponica [PDF]

open access: yes, 2002
The specific roles of corticosterone in promotion of avian migration remain unclear even though this glucocorticosteroid is elevated in many migrating bird species.

Drivers of Dyadic Cofeeding Tolerance in Pan: A Composite Measure Approach

open access: yesBiology, 2022
This study aimed to construct a composite model of Dyadic Cofeeding Tolerance (DCT) in zoo-housed bonobos and chimpanzees using a validated experimental cofeeding paradigm and to investigate whether components resulting from this model differ between the

How methanotrophs respond to pH: A review of ecophysiology

open access: yesFrontiers in Microbiology, 2023
Varying pH globally affects terrestrial microbial communities and biochemical cycles. Methanotrophs effectively mitigate methane fluxes in terrestrial habitats. Many methanotrophs grow optimally at neutral pH.

Functional traits of expanding, thicket-forming shrubs: contrasting strategies between exotic and native species [PDF]

open access: yes, 2017
Woody expansion has been documented for decades in many different systems globally, often yielding vast changes in ecosystem functioning. While causes and consequences of woody expansion have been well documented, few studies have addressed plant ...

Decreasing parental task specialization promotes conditional cooperation

open access: yesScientific Reports, 2017
How much to invest in parental care and by who remain puzzling questions fomented by a sexual conflict between parents. Negotiation that facilitates coordinated parental behaviour may be key to ease this costly conflict.

Geobacter, Anaeromyxobacter and Anaerolineae populations are enriched on anodes of root exudate-driven microbial fuel cells in rice field soil [PDF]

open access: yes, 2015
Plant-based sediment microbial fuel cells (PMFCs) couple the oxidation of root exudates in living rice plants to current production. We analysed the composition of the microbial community on anodes from PMFC with natural rice field soil as substratum for

Reply to Farine and Aplin: Chimpanzees choose their association and interaction partners [PDF]

open access: yes, 2019
Farine and Aplin (1) question the validity of our study reporting group-specific social dynamics in chimpanzees (2). As alternative to our approach, Farine and Aplin advance a “prenetwork permutation” methodology that tests against random assortment (3).

The Female Perspective of Personality in a Wild Songbird: Repeatable Aggressiveness Relates to Exploration Behaviour

open access: yesScientific Reports, 2017
Males often express traits that improve competitive ability, such as aggressiveness. Females also express such traits but our understanding about why is limited.
