Scale dependence in remotely sensed biodiversity: Leveraging continental‐scale imaging spectroscopy from the National Ecological Observatory Network

Remote Sensing in Ecology and Conservation, EarlyView.
Imaging spectroscopy enables large‐scale biodiversity assessment, yet spectral diversity metrics are scale dependent. Across 15 NEON ecosystems, we find that spectral richness increases sub‐linearly from 3600 m2 to 4 km2, whereas spectral divergence shows weak or inconsistent scaling with area, underscoring the importance of scale‐aware interpretation ...

Spatial Evolution of Prosopis Invasion and its Effects on LULC and Livelihoods in Baringo, Kenya

Remote Sensing, 2019
Woody alien plant species have been deliberately introduced globally in many arid and semi-arid regions, as they can provide services and goods to the rural poor.

Differences in mammal community response to highway construction across different levels of human land use

Wildlife Biology, EarlyView.
Worldwide, transportation agencies have been involved in road mitigation efforts to reduce road mortality and promote connectivity of endangered species. Baseline data on how mammals respond to highway construction, however, are rarely collected in road mitigation and monitoring studies, including in the USA.

Effects of selective harvest on antler size of white‐tailed deer in Texas, USA

Wildlife Monographs, EarlyView.
We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

Rapid scavenging of avian carcasses in the desert Southwest: Implications for mortality surveys not associated with infrastructure

Wildlife Society Bulletin, EarlyView.
We placed 214 avian carcasses in a desert environment at locations not associated with infrastructure and monitored their removal by scavengers using camera traps. We found that 211 of the 214 carcasses were scavenged and median persistence time was 1.53 days. None of the predictor variables were informative of carcass persistence times.

Studies on Bioadhesive Granules I: Granules Formulated with Prosopis africana (Prosopis) Gum.

Chemical and Pharmaceutical Bulletin, 2000
Prosopis gum (PG) extracted from Prosopis africana was investigated for bioadhesive delivery of theophylline (TPL). Bioadhesive granules containing TPL were formulated and the bioadhesive properties evaluated using adhesion of the granules onto a porcine intestinal mucus surface.

Quantifying the impact of environmental education and outreach on citizen science reports of an endangered neotropical raptor

Conservation Science and Practice, EarlyView.
In this paper, we show the importance of environmental education activities to increase citizen science field sightings of an endangered and elusive raptor species, and we analyze the effect of sociodemographic variables on these outcomes. In 1 year, sightings reported by the people reached with the outreach campaign doubled those of the last 10 years ...
