Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach

The Journal of Wildlife Management, EarlyView.
We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.

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

International 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 ...

Biogeography of Endemic Dragonflies of the Ozark-Ouachita Interior Highlands [PDF]

, 2019
A common pattern across many taxonomic groups is that relatively few species are widespread while the majority are restricted in their geographic ranges. Such species distributions are used to inform conservation status, which poses unique challenges for

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

Oikos, EarlyView.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.

Functional diversity in agricultural landscapes: evidence of long‐term clustering and multi‐scale effects of land use on avian communities

Oikos, EarlyView.
Functional diversity (FD) is an essential community property connecting biodiversity, ecosystem functioning, and conservation objectives. In agricultural landscapes, avian communities, which play key functional roles, are facing large‐scale biodiversity erosion, largely due to land‐use changes.

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

Oikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Quantitative synthesis of the effects of drought on community composition and species interactions in terrestrial ecosystems

Oikos, EarlyView.
Droughts, increasingly frequent under human‐driven climate change, are expected to intensify globally. Both pulsed and prolonged droughts can strongly affect organismal survival and population dynamics, potentially altering terrestrial communities and ecosystems.
