Temporal and spatial variations in freshwater 14C reservoir effects: Lake Myvatn, Northern Iceland [PDF]

open access: yes, 2010
Lake Mývatn is an interior highland lake in northern Iceland that forms a unique ecosystem of international scientific importance and is surrounded by a landscape rich in archaeological and palaeoenvironmental sites.

Omnivory by planktivores stabilizes plankton dynamics, but may either promote or reduce algal biomass [PDF]

open access: yes, 2010
Classical models of phytoplankton–zooplankton interaction show that with nutrient enrichment such systems may abruptly shift from limit cycles to stable phytoplankton domination due to zooplankton predation by planktivorous fish.

Stable Carbon and Nitrogen Isotope Analysis Explores Diverse Domestic Goose Management Practices in Medieval and Postmedieval Russia

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Studying goose domestication through archaeological finds has been challenging due to the similar skeletal morphology of the European domestic goose and its wild progenitor, the greylag goose (Anser anser). We analyzed stable carbon (δ13C) and nitrogen (δ15N) isotopes from bone collagen of subfossil domestic and potentially domestic geese to ...

Functional macronutritional generalism in a large omnivore, the brown bear

open access: yesEcology and Evolution, 2018
We combine a recently developed framework for describing dietary generalism with compositional data analysis to examine patterns of omnivory in a large widely distributed mammal.

Effects of forest fragmentation on the vertical stratification of neotropical bats [PDF]

open access: yes, 2020
Vertical stratification is a key component of the biological complexity of rainforests. Understanding community- and species-level responses to disturbance across forest strata is paramount for evidence-based conservation and management.

Benthic megafauna and the functioning of macroalgal forests and urchin barrens

open access: yesOikos, EarlyView.
Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

open access: yesOikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...

Food and feeding habits of Synodontis nigrita from the Osun River, SW Nigeria [PDF]

open access: yes, 2003
An investigation was conducted into the food and feeding habits of Synodontis nigrita from the Osun River near Epe, Lagos, Nigeria. The food items in the stomach of the S.

Embodied urban design: Fostering nature connectedness for pro‐conservation behaviour

open access: yesPeople and Nature, EarlyView.
Abstract Those who feel more connected with nature are more likely to act in ways that support biodiversity. How connected people feel with nature depends in part on how meaningfully it figures into their experience of the built environment. Despite an increase in urban greening measures, these approaches often overlook how people perceive, interact ...

Raccoon Dogs Adjust Diel Visitation at Scent Marking Latrines to Reduce Human Disturbance in Urban Areas

open access: yesEcology and Evolution
Human activity and development have a variety of effects on wildlife behavior, often prompting urban wildlife to adopt behavioral strategies—including spatiotemporal activity adjustments—that facilitate persistence in human‐dominated environments.
