Corticosterone Under Experimental Manipulation of Nutrition and Parasite Burden in a Wild Rodent System

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Environmental pressures shape survival and life‐history dynamics partly by triggering the release of glucocorticoids, whose short‐term benefits but long‐term costs make it essential to understand what drives their levels. Here, we used an experimental manipulation of two environmental stressors—food availability and parasite burden—to directly

CAPTURE-RECAPTURE METHODS WITHUCA

The Biological Bulletin, 1972
1. Estimates of the size of a population of sand fiddler crabs, Uca pugilator (Bosc), were made with the Lincoln Index and Jackson's "positive" and "negative" models in the mobile phase of the activity cycle, and by stratified sampling of the immobile phase.2.

From Imposter to Original: How Organizational Leaders Shape and Develop a Leader Identity Through Meaning‐Making of Experiences

Journal of Organizational Behavior, EarlyView.
ABSTRACT This article describes how people in formal leadership roles shape and develop a leader identity through meaning‐making of experiences across time and situations. Drawing on qualitative data from in‐depth life narrative interviews with 22 organizational leaders, enriched through photo and object elicitation techniques as well as timeline ...

Parameter Redundancy with Applications in Statistical Ecology [PDF]

, 2014
This thesis is concerned with parameter redundancy in statistical ecology models. If it is not possible to estimate all the parameters, a model is termed parameter redundant.

Estimating IPv4 address space usage with capture-recapture

, 2013
As of April 2013 almost 95% of the IPv4 address space has been allocated. Yet, the transition to IPv6 is still relatively slow. One reason could be existing 'IPv4 reserves'---allocated but unused IPv4 addresses.

Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction

Strategic Change, EarlyView.
ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.

A comparison of monitoring methods for inferring demographics of a pond‐breeding amphibian population over 14 years

The Journal of Wildlife Management, EarlyView.
We used 4 sampling methods to estimate or index the abundance and sex ratio of spotted salamanders (Ambystoma maculatum) over 14 years. The present study highlights the importance of considering individual heterogeneity in capture probability when estimating abundance of pond‐breeding amphibians from capture data with imperfect detection. Abstract Long‐

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...
