Cougar density on the Oregon Coast: Using dead recovery modeling in an open population
The Journal of Wildlife Management, EarlyView.The primary objective of this study was to determine cougar density in western Oregon. Our results demonstrate that integrating DNA collected via bio‐darting, mandatory hunter‐harvest check‐ins, and GPS collar data into the OPCR2 is a reliable method for estimating cougar densities in densely forested coastal systems.

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status
Nordic Journal of Botany, EarlyView.Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Genetic and morphological identification of a recurrent Dicksonia tree fern hybrid in New Zealand.
PLoS ONE, 2019 Hybridization is common in many ferns and has been a significant factor in fern evolution and speciation. However, hybrids are rare between the approximately 30 species of Dicksonia tree ferns world-wide, and none are well documented.

Mitigating memory requirements for random trees/ferns
2015 IEEE International Conference on Image Processing (ICIP), 2015 Randomized sets of binary tests have appeared to be quite effective in solving a variety of image processing and vision problems. The exponential growth of their memory usage with the size of the sets however hampers their implementation on the memory-constrained hardware generally available on low-power embedded systems.

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin
Oikos, EarlyView.Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.
