Estimating effective population size using close‐kin mark–recapture

Methods in Ecology and Evolution
Close‐kin mark–recapture (CKMR) is a method that allows estimating population census size, among other parameters, through the observed number of pairs that are close‐kin including parent–offspring pairs (POPs) and half‐sibling pairs (HSPs).

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 ...

Recommendations for photo-identification methods used in capture-recapture models with cetaceans

, 2015
Capture-recapture methods are frequently employed to estimate abundance of cetaceans using photographic techniques and a variety of statistical models. However, there are many unresolved issues regarding the selection and manipulation of images that can ...

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.

Evidence of high longevity in an Island lacertid, Teira dugesii (Milne-Edwards, 1829). First data on wild specimens

Acta Herpetologica, 2012
Using the technique of capture, mark and recapture, here is reported a case of high longevity in the Madeiran lizard, Teira dugesii. It is one of the highest reported values for lacertid lizards (16 years or more) in a wild population.

Finite mixture models of heterogeneous capture probabilities for mark-recapture estimation of closed population size

, 2001
Heterogeneity in capture probabilities among animals is a common problem for estimation of animal population size from mark-recapture data. We model animals as belonging to discrete groups in which animals have the same probabilities of first capture and

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 ...

Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Supply chain disruptions can lead to both tactical (i.e., loss of short‐term sales during a disruption) and strategic (i.e., loss of long‐term market share) consequences. We model the impact of a supply disruption on competing supply chains in which two firms compete for a limited backup supply.
