Assessing rotation-invariant feature classification for automated wildebeest population counts [PDF]

, 2016
Accurate and on-demand animal population counts are the holy grail for wildlife conservation organizations throughout the world because they enable fast and responsive adaptive management policies.

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells

FEBS Open Bio, EarlyView.
Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.

Propagating observation errors to enable scalable and rigorous enumeration of plant population abundance with aerial imagery

Methods in Ecology and Evolution
Estimating and monitoring plant population size is fundamental for ecological research, as well as conservation and restoration programs. High‐resolution imagery has potential to facilitate such estimation and monitoring.

Simulating carnivore movements: An occupancy–abundance relationship for surveying wolves

Wildlife Society Bulletin, 2012
Where carnivore species exist at low densities, are cryptic, and inhabit forested habitats where detection is low, survey approaches commonly rely on observation of tracks.

Anchorage‐independent and faster growth in clonal population from UV‐irradiated NER‐deficient cells

FEBS Open Bio, EarlyView.
UV‐irradiated cells expressing a DDB2 mutant protein unable to interact with PCNA (DDB2PCNA‐) form clones able to grow without anchorage. Different experimental approaches reveal heterogeneity in cell cycle regulation and drug response within these clones, emphasizing the crucial role of the DDB2‐PCNA interaction in preventing cellular transformation ...

Seasonal habitat‐based density models for a marine top predator, the harbor porpoise, in a dynamic environment

Ecosphere, 2016
Effective species conservation and management requires information on species distribution patterns, which is challenging for highly mobile and cryptic species that may be subject to multiple anthropogenic stressors across international boundaries ...

Distance estimation experiment for aerial minke whale surveys

NAMMCO Scientific Publications, 2009
A comparative study between aerial cue–counting and digital photography surveys for minke whales conducted in Faxaflói Bay in September 2003 is used to check the perpendicular distances estimated by the cue-counting observers.

A Feasibility Study of Using Unmanned Aerial Vehicles to Survey Avian Abundance by Using Audio Recording

, 2015
Roadside counts are commonly used to assess songbird abundance, but they result in oversampling habitat edges and underrepresenting core habitats, areas of steep terrain, and wetlands.
