Morphological and Behavioral Correlates of Long-Term Bird Survival in Selectively Logged Forest

open access: yesFrontiers in Ecology and Evolution, 2019
The response of biodiversity to land-use change has been a central focus in applied ecological research for close to half a century. However, despite a vast body of literature, our understanding of how species' traits influence demographic vital rates in

Residency patterns and apparent survival in a cavity-nesting bird: population consequences of nest-box supplementation revealed by a long-term study

open access: yesAvian Conservation and Ecology, 2021
Phenotypic plasticity may help organisms persist in modified habitats. Yet, its adaptive value is frequently ignored because fitness consequences are not explored at the required time scale.

Whole brain apparent diffusion coefficient measurements correlate with survival in glioblastoma patients [PDF]

open access: yesJournal of Neuro-Oncology, 2019
Abstract Introduction Glioblastoma (GBM) is the most common malignant primary brain tumor, and methods to improve the early detection of disease progression and evaluate treatment response are highly desirable. We therefore explored changes in whole-brain apparent diffusion coefficient (ADC) values with respect to survival (progression-free [PFS ...

Correlating tropical climate with survival of an Arctic-breeding, trans-equatorial migrant seabird

open access: yesArctic Science, 2018
Extreme climate can negatively affect survival through increased physiological demands or by reducing prey availability. This can have significant population-level consequences for organisms with low reproductive rates, such as seabirds.

Survival of Adult Songbirds in Boreal Forest Landscapes Fragmented by Clearcuts and Natural Openings

open access: yesAvian Conservation and Ecology, 2008
There exists little information on demographic responses of boreal songbirds to logging. We conducted a 4-yr (2003-2006) songbird mark-recapture study in western Newfoundland, where land cover is a naturally heterogeneous mosaic of productive spruce-fir ...

Secondary schooling and rural youth transitions in Lesotho and Zimbabwe [PDF]

open access: yes, 2004
Based on case studies centred on two rural secondary schools in Lesotho and Zimbabwe, this paper examines the gendered impacts of schooling on young people’s transitions to adulthood.

Surviving in the city: higher apparent survival for urban birds but worse condition on noisy territories [PDF]

open access: yesEcosphere, 2018
AbstractAnthropogenic landscapes and soundscapes impose strong selective pressures on a number of species, which can manifest in changes in vocalizations, foraging strategies, predator vigilance, and reproductive success. However, few studies have examined survival rates, a major component of fitness, across urban landscapes and soundscapes.

Estimating demographic parameters using a combination of known-fate and open N-mixture models

open access: yes, 2015
1. Accurate estimates of demographic parameters are required to infer appropriate ecological relationships and inform management actions. Recently developed N-mixture models use count data from unmarked individuals to estimate demographic parameters, but
