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.

Flows on rooted trees and the Narayana idempotents [PDF]
, 2012 Several generating series for flows on rooted trees are introduced, as elements in the group of series associated with the Pre-Lie operad. By combinatorial arguments, one proves identities that characterise these series.

The Journal of Wildlife Management, EarlyView.Antler characteristics are influenced by a combination of genetics, age, and environmental factors, notably habitat quality and resource availability. In this study, we explored how diverse environmental factors, including climate and land cover composition, affect antler size, tine configuration, and the distribution of record‐scoring white‐tailed ...

Forest Stand Structure and Primary Production in relation to Ecosystem Development, Disturbance, and Canopy Composition [PDF]
, 2016 Temperate forests are complex ecosystems that sequester carbon (C) in biomass. C storage is related to ecosystem-scale forest structure, changing over succession, disturbance, and with community composition.

Wild pig habitat use impacted by prescribed fire in the William B. Bankhead National Forest, USA
The Journal of Wildlife Management, EarlyView.Natural resource management activities like integrated wild pig control programs and 3–5‐year interval prescribed burning can reduce wild pig activity and habitat but can have an unintended side effect of allowing them to thrive in sensitive and protected areas, where access and tools are restricted.

Another dimension from LiDAR – Obtaining foliage density from full waveform data [PDF]
, 2011 LiDAR tells the user where surfaces are, not what they are. In this study we investigate the potential for waveform LiDAR to provide more information on the nature of the returns over forestry. Waveform LiDAR was acquired for ten Pinus radiata plots in a

Population dynamics, survival, and movements of Texas tortoises in a national park in southern Texas
The Journal of Wildlife Management, EarlyView.Texas tortoise abundance in a small national park in South Texas, USA, declined by >25%, from an estimated 273 tortoises in 2014 to 204 tortoises in 2024. The severity of the decline varied across survey units, but abundance remained highest in areas having greater canopy cover and experiencing less invasion by Guinea grass.

Die Baumkronenspinnen (Araneae) des Leipziger Auwaldes [PDF]
, 2012 The canopy spiders of the floodplain forest in Leipzig have become a focus of ecological studies in recent years. In 2006 we sampled 30 tree canopies in the ‘Burgaue’ nature reserve with pyrethrum knock-down fogging, recording 502 adult spiders belonging
