Motivated by the need to estimate the abundance of marine mammal populations to inform
conservation assessments, especially relating to fishery bycatch, this paper provides …

Assessing the non-lethal effects of disturbance and their population-level consequences is a
significant ecological and conservation challenge, because it requires extensive baseline …

Estimates of population size and trends are essential for effective conservation and
management of wildlife populations. For harbour seals (Phoca vitulina), these data are …

Photo-identification (photo-ID) with camera traps was examined as a non-invasive method
for studying and monitoring the endangered Saimaa ringed seal Phoca hispida saimensis …

Understanding why animals move as they do when searching for resources is a central
question in ecology, and a prerequisite for the development of predictive process-based …

Site fidelity is commonly observed in pinnipeds and has direct consequences for individual
space use and population dynamics. Here, we used photo-identification recapture data to …

Migratory movements in response to seasonal resources often influence population
structure and dynamics. Yet in mobile marine predators, population genetic consequences …

Reliable population estimates are fundamental to the conservation of endangered species.
We evaluate here the use of photo-identification (photo-ID) and mark-recapture techniques …

Metapopulation theory assumes a balance between local decays/extinctions and local
growth/new colonisations. Here we investigate whether recent population declines across …

Methods for long‐term monitoring of coastal species such as harbor seals (Phoca vitulina)
are often costly, time‐consuming, and highly invasive, underscoring the need for improved …
