Effect of sociality and season on gray wolf (Canis lupus) foraging behavior: implications for estimating summer kill rate. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: Understanding how kill rates vary among seasons is required to understand predation by vertebrate species living in temperate climates. Unfortunately, kill rates are only rarely estimated during summer.

Where wolves kill moose: the influence of prey life history dynamics on the landscape ecology of predation. [PDF]

open access: yesPLoS ONE, 2014
The landscape ecology of predation is well studied and known to be influenced by habitat heterogeneity. Little attention has been given to how the influence of habitat heterogeneity on the landscape ecology of predation might be modulated by life history

Environmental and anthropogenic features mediate risk from human hunters and wolves for moose

open access: yesEcosphere, 2022
Landscape characteristics, seasonal changes in the environment, and daylight conditions influence space use and detection of prey and predators, resulting in spatiotemporal patterns of predation risk for the prey.

Tumor Hypoxia Heterogeneity Affects Radiotherapy: Inverse-Percolation Shell-Model Monte Carlo Simulations

open access: yesEntropy, 2022
Tumor hypoxia was discovered a century ago, and the interference of hypoxia with all radiotherapies is well known. Here, we demonstrate the potentially extreme effects of hypoxia heterogeneity on radiotherapy and combination radiochemotherapy. We observe

Using Machine Learning for Remote Behaviour Classification—Verifying Acceleration Data to Infer Feeding Events in Free-Ranging Cheetahs

open access: yesSensors, 2021
Behavioural studies of elusive wildlife species are challenging but important when they are threatened and involved in human-wildlife conflicts. Accelerometers (ACCs) and supervised machine learning algorithms (MLAs) are valuable tools to remotely ...

Moss kill dates and modeled summer temperature track episodic snowline lowering and ice cap expansion in Arctic Canada through the Common Era [PDF]

open access: yesClimate of the Past, 2023
Most extant ice caps mantling low-relief Arctic Canada landscapes remained cold based throughout the late Holocene, preserving in situ bryophytes killed as ice expanded across vegetated landscapes.

Patterns of Lynx Predation at the Interface between Protected Areas and Multi-Use Landscapes in Central Europe. [PDF]

open access: yesPLoS ONE, 2015
In Central Europe, protected areas are too small to ensure survival of populations of large carnivores. In the surrounding areas, these species are often persecuted due to competition with game hunters.

Wright-Fisher diffusion with negative mutation rates [PDF]

open access: yes, 2013
We study a family of n-dimensional diffusions, taking values in the unit simplex of vectors with nonnegative coordinates that add up to one. These processes satisfy stochastic differential equations which are similar to the ones for the classical Wright ...

Risk Assessment Method for Bullheading Killing Based on the Uncertainty of Formation Parameters

open access: yesLithosphere, 2022
To analyze the risks caused by the uncertainty of formation parameters to bullheading killing, a method for quantitatively evaluating the bullheading killing risks is established.

Biocontainment of Genetically Engineered Algae

open access: yesFrontiers in Plant Science, 2022
Algae (including eukaryotic microalgae and cyanobacteria) have been genetically engineered to convert light and carbon dioxide to many industrially and commercially relevant chemicals including biofuels, materials, and nutritional products. At industrial
