Utilization of Capture-Mark-Recapture for the Study of Recruitment and Population Growth Rate

Biometrics, 1996
Capture-mark-recapture data has been extensively used for the study of survival. However, recruitment and population growth rate can be investigated as well. The study of recruitment is shown to be equivalent to the study of survival in reverse and can be carried out by inverting capture histories.

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle

Oikos, EarlyView.
The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

The strength of the association between heterozygosity and probability of interannual local recruitment increases with environmental harshness in blue tits [PDF]

, 2016
The extent of inbreeding depression and the magnitude of heterozygosity–fitness correlations (HFC) have been suggested to depend on the environmental context in which they are assayed, but little evidence is available for wild populations.

A amostragem estratificada aprimora a compreensão das redes entre morcegos e frutos na Mata Atlântica meridional

Oikos, EarlyView.
Few studies have sought to understand the vertical patterns of bat–fruit systems, and therefore, it is not possible to evaluate whether interpretations based on data collected from a single stratum adequately represent the interaction patterns of this system. In this context, we evaluated the dissimilarity in the assemblage of frugivorous bats, plants,

Fungal infection has sublethal effects in a lowland subtropical amphibian population

BMC Ecology, 2018
Background The amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd), has been implicated as a primary cause of decline in many species around the globe.

Data analysis model selection for estimating local population size of the Risso’s dolphin (Grampus griseus) in the Azores [PDF]

, 2013
27th Annual Conference of the European Cetacean Society. Setúbal, Portugal, 8-10 April 2013.Different models estimating cetacean population size require making assumptions about the marking and recapturing of individuals, and on the structure of the ...

Linking differences in personality to demography in the wandering albatross

Oikos, EarlyView.
Population dynamics are shaped by individual differences. With a good understanding of the relationships between individual differences and vital rates, population models can be improved to yield more realistic and detailed demographic projections. Personality is expected to shape individual differences in performance.

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.

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

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 ...
