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.

Global analysis of annual survival among shorebirds reveals a negative effect of migration distance and a decline in recent decades

Oikos, EarlyView.
Annual survival is a key demographic parameter driving population trends in wildlife populations. However, despite numerous species‐specific or regional studies, global reviews of the factors affecting the survival of declining taxa remain scarce. Here, we investigated annual survival of fledged immature and adult shorebirds, a globally‐distributed and

Evaluation of population densities of the common wolf spider Pardosa agrestis (Araneae: Lycosidae) in Hungarian alfalfa fields using mark-recapture

European Journal of Entomology, 2000
The absolute population density of adult Pardosa agrestis (Westring, 1862), the dominant epigeic spider species in many arable lands in Central Europe, was quantified in two alfalfa fields using a multiple mark-recapture method.

A comparison of linear transect and capture recapture methods results in Iranian Jerboa population density and abundance estimation in Mirabad plains, Shahreza

یافته‌های نوین در علوم زیستی, 2019
During a period from spring 2008 till fall 2010, Iranian Jerboa population abundance was estimated using distance (linear transect) and capture-recapture methods in the Mirabad plains near Shahreza city in Isfahan Province.

Habitat fragmentation and amount drive within‐species variation in dispersal kernels and limit transferability across landscapes

Oikos, EarlyView.
Dispersal is a key ecological trait that ensures connectivity, gene flow, and range dynamics, yet empirical information about how dispersal distances vary within species remains scarce. Many studies, investigating for instance connectivity conservation, use typical species‐specific dispersal kernels without accounting for the fact that these kernels ...

Assessing the suitability of a one‐time sampling event for close‐kin mark‐recapture: A caribou case study

Ecology and Evolution
Abundance estimation is frequently an objective of conservation and monitoring initiatives for threatened and other managed populations. While abundance estimation via capture–mark–recapture or spatially explicit capture–recapture is now common, such ...

Using participatory scenario planning to explore the synergies and trade‐offs from upland treescape expansion

People and Nature, EarlyView.
Abstract The future of land use in the UK uplands is highly debated, with growing interest in increasing tree cover and other land use changes, alongside a desire to maintain traditional land use patterns and practices. Treescape expansion is likely to result in synergies and trade‐offs between different outcomes, so integrating stakeholder preferences

Digital surveillance of animals and nature recovery

People and Nature, EarlyView.
Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.
