Nesting habitat selection and distribution of an avian top predator in the Canadian Arctic

open access: yesArctic Science, 2018
Detecting and planning for ecosystem changes from climate and land-use alteration is limited by uncertainty about the current distribution of many species.

Revisiting resource selection probability functions and single‐visit methods: clarification and extensions [PDF]

open access: yesMethods in Ecology and Evolution, 2015
SummaryModels accounting for imperfect detection are important. Single‐visit (SV) methods have been proposed as an alternative to multiple‐visit methods to relax the assumption of closed population. Knape & Korner‐Nievergelt (Methods in Ecology and Evolution, 2015) showed that under certain models of probability of detection,SVmethods are ...

Density Estimation Trees as fast non-parametric modelling tools

open access: yes, 2016
Density Estimation Trees (DETs) are decision trees trained on a multivariate dataset to estimate its probability density function. While not competitive with kernel techniques in terms of accuracy, they are incredibly fast, embarrassingly parallel and ...

Network service chaining with efficient network function mapping based on service decompositions [PDF]

open access: yes, 2015
Network Service Chaining (NSC) is a service concept which promises increased flexibility and cost-efficiency for future carrier networks. The two recent developments, Network Function Virtualization (NFV) and Software-Defined Networking (SDN), are ...

Accuracy of resource selection functions across spatial scales

open access: yesDiversity and Distributions, 2006
ABSTRACTResource selection functions (RSFs) can be used to map suitable habitat of a species based on predicted probability of use. The spatial scale may affect accuracy of such predictions. To provide guidance as to which spatial extent or grain is appropriate and most accurate for animals, we used the concept of hierarchical selection orders to ...

Nesting, brood rearing, and summer habitat selection by translocated greater sage‐grouse in North Dakota, USA

open access: yesEcology and Evolution, 2021
Human enterprise has led to large‐scale changes in landscapes and altered wildlife population distribution and abundance, necessitating efficient and effective conservation strategies for impacted species.

Self-optimization, community stability, and fluctuations in two individual-based models of biological coevolution

open access: yes, 2007
We compare and contrast the long-time dynamical properties of two individual-based models of biological coevolution. Selection occurs via multispecies, stochastic population dynamics with reproduction probabilities that depend nonlinearly on the ...

Group-size-mediated habitat selection and group fusion-fission dynamics of bison under predation risk [PDF]

open access: yes, 2009
For gregarious animals the cost-benefit trade-offs that drive habitat selection may vary dynamically with group size, which plays an important role in foraging and predator avoidance strategies.

Evaluating the Utility of Paired Tumor and Germline Targeted DNA Sequencing for Pediatric Oncology Patients: A Single Institution Report

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate the diagnostic yield and utility of universal paired tumor–normal multigene panel sequencing in newly diagnosed pediatric solid and central nervous system (CNS) tumor patients and to compare the detection of germline pathogenic/likely pathogenic variants (PV/LPVs) against established clinical referral criteria for cancer ...

Selecting Focal Songbird Species for Biodiversity Conservation Assessment: Response to Forest Cover Amount and Configuration

open access: yesAvian Conservation and Ecology, 2007
Conservation of biodiversity is now a firmly entrenched objective of sustainable forest management, and emulating natural disturbance has been widely adopted as a conservation strategy. Yet the foundation for this approach is still very much a hypothesis
