Reliability of trans‐generational genetic mark–recapture (tGMR) for enumerating Pacific salmon
As Pacific salmon (Oncorhynchus spp.) decline across much of their range, it is imperative to further develop minimally invasive tools to quantify population abundance.

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 ...

ABSTRACT Conservation assessments of imperiled species require information on population structure, abundance, and connectivity which benefit from integrated demographic and genetic data. Humboldt martens (Martes caurina humboldtensis) are a federally threatened subspecies of Pacific marten (Martes caurina) whose conservation has been hindered by ...

ABSTRACT Supportive breeding programs are widely implemented to counteract demographic collapse in threatened populations. Their long‐term success, however, depends on maintaining genetic diversity while ensuring that released individuals contribute effectively to wild populations.

Population size is a key parameter for the conservation of animal species. Close‐kin mark‐recapture (CKMR) relies on the observed frequency and type of kinship among individuals sampled from the population to estimate population size.

ABSTRACT The consequences of mis‐managing vulnerable stocks (i.e., those with low productivity and high susceptibility to depletion) are high and potentially permanent. To support sustainable fisheries management, stock assessments can be improved by increasing the quantity and quality of fishery‐independent survey (i.e., survey) data.

Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

Stock depletion level is an important concept in the assessment and management of exploited fish stocks because it is often used in conjunction with reference points to infer stock status.

Total Numbers and Movements of Photo‐Identified Subantarctic (Type D) Killer Whales
ABSTRACT The distinctive Subantarctic (Type D) killer whale (DKW) (Orcinus orca) is a highly divergent and apparently inbred form previously known only from three mass strandings and several dozen at‐sea sightings, primarily from Patagonian toothfish (Dissostichus eleginoides) longline vessels in the southern Indian Ocean and from tourism vessels in ...
