Distance of movement in three threatened butterfly species

Ecological Entomology, EarlyView.
Multi‐year mark–recapture analysis using net displacement and Cormack–Jolly–Seber models shows similar daily detectability (0.17–0.22) among species, supporting robust interspecific comparisons. Dispersal kernels differ: lognormal best for Euphydryas aurinia and Parnassius apollo, exponential for Phengaris arion; P.

A half century of monitoring reveals contrasting survival responses of Icelandic seabirds to climate and fisheries pressures

Ibis, EarlyView.
Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.

Use of capture–recapture models to evaluate abundance and dynamics of a stocked Muskellunge population

Aquaculture, Fish and Fisheries
To evaluate the success of a stocking program in Fox Lake, Minnesota, adult (≥76 cm total length) Muskellunge were captured with large nearshore trap nets and individually marked with passive integrated transponder tags during the 2011–2013 and 2015–2017

Nest Success and Hatchling Survival of American Alligators Within Inland Wetlands of East Texas [PDF]

, 2012
Because of liberalization of American alligator (Alligator mississippiensis) harvest management in Texas, estimates of nest success and hatchling survival for inland populations are essential for long-term, sustainable population and harvest management ...

Inshore marine coastal zone migration patterns in Atlantic salmon post‐smolts emigrating from eight rivers in north‐east Scotland

Journal of Fish Biology, EarlyView.
Abstract Atlantic salmon, Salmo salar, migrate through multiple habitat types, each having the potential to impact differently upon migration success. The inshore marine coastal zone is arguably disproportionately impacted by potential stressors on populations.

Age‐Specific Survival Estimation of a Eurasian Crane Population Highlights a Long‐Term Decline in Juvenile Survival

Ecology and Evolution, Volume 16, Issue 2, February 2026.
The Eurasian crane (Grus grus), a symbol of conservation success in Europe, has made an impressive recovery. However, our results show that over the study period, juvenile survival declined by almost 30% overall, while sub‐adults experienced a smaller decrease, and adults showed no change.

Population ecology of Chaetophractus vellerosus: the first report for an armadillo in South America

Zoologia (Curitiba), 2017
The aim of this work was to obtain the first estimates of survival rates (S), capture probability (p) and life expectancy for armadillos in South America by analyzing capture-mark-recapture data obtained from a population of Chaetophractus vellerosus ...

Extreme polygyny results in intersex differences in age-dependent survival of a highly dimorphic marine mammal

Royal Society Open Science, 2023
Developmental differences in vital rates are especially profound in polygamous mating systems. Southern elephant seals (Mirounga leonina) are highly dimorphic and extremely polygynous marine mammals.

Physiology and Survival of Intertidal Calcifiers in Two Contrasting Upwelling Systems

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study evaluates the physiological responses and survival of two intertidal mollusk species, Chiton granosus and Scurria zebrina, across contrasting upwelling environments. We found that metabolic rates and survival differ between populations exposed to seasonal versus semi‐permanent upwelling.

Patch-Scale Movement Dynamics in the Iowa Grassland Butterflies \u3ci\u3eSpeyeria Cybele\u3c/i\u3e and \u3ci\u3eMegisto Cymela\u3c/i\u3e (Lepidoptera: Nymphalidae) [PDF]

, 2018
An understanding of the movement dynamics of invertebrates can be critical to their conservation, especially when managing relatively small, isolated habitats. Most studies of butterfly movement have focused on metapopulation dynamics at relatively large
