Consequences of past and present harvest management in a declining flyway population of common eiders Somateria mollissima
Sign Up to like & getrecommendations! Published in 2019 at "Ecology and Evolution"
DOI: 10.1002/ece3.5707
Abstract: Abstract Harvested species population dynamics are shaped by the relative contribution of natural and harvest mortality. Natural mortality is usually not under management control, so managers must continuously adjust harvest rates to prevent overexploitation. Ideally,… read more here.

Searching for M: Is there more information about natural mortality in stock assessments than we realize?
Sign Up to like & getrecommendations! Published in 2017 at "Fisheries Research"
DOI: 10.1016/j.fishres.2016.12.009
Abstract: Natural mortality (M) is both a highly consequential and difficult process to estimate in stock assessments. Because of its correlation with other influential parameters, and the inadequacy of data to understand how it varies with… read more here.

Behavior, escapement, and mortality of adult Muskellunge in Midwestern reservoirs
Sign Up to like & getrecommendations! Published in 2021 at "Fisheries Research"
DOI: 10.1016/j.fishres.2021.105945
Abstract: Abstract Muskellunge Esox masquinongy is a popular species commonly introduced to warm-water reservoirs; however, little is known about seasonal habitat use and movement in these systems which may result in reservoir escapement and reduced Muskellunge… read more here.

DOI: 10.1016/j.fishres.2021.106062
Abstract: Abstract Stock assessment models often require an external estimate of the natural mortality rate (M) that is usually assumed to be the same for all ages and years in the model. Although the fixed M… read more here.

DOI: 10.1016/j.fishres.2021.106071
Abstract: Abstract We consider the challenge in estimating the natural mortality, M , in a standard statistical fish stock assessment model based on time series of catch- and abundance-at-age data. Though anecdotal evidence and empirical experience… read more here.

DOI: 10.1016/j.gecco.2020.e01082
Abstract: Abstract Non-natural mortality is a major threat to animal conservation worldwide. Its origins are extremely diverse and include infrastructures that cause animal casualties. Its effects are widely felt and so prioritization criteria are necessary when… read more here.

Empirical links between natural mortality and recovery in marine fishes
Sign Up to like & getrecommendations! Published in 2017 at "Proceedings of the Royal Society B: Biological Sciences"
DOI: 10.1098/rspb.2017.0693
Abstract: Probability of species recovery is thought to be correlated with specific aspects of organismal life history, such as age at maturity and longevity, and how these affect rates of natural mortality (M) and maximum per… read more here.

DOI: 10.7717/peerj.14989
Abstract: The increase in temperature resulting from global climate change can directly affect the survival of fish and therefore population parameters such as natural mortality (M). The estimation of this parameter and the understanding of the… read more here.

Natural mortality estimates throughout the life history of the sea cucumber Isostichopus Badionotus (Holothuroidea: Aspidochirotida)
Sign Up to like & getrecommendations! Published in 2018 at "PeerJ"
DOI: 10.7717/peerj.5235
Abstract: The Natural Mortality coefficient (M) is a key parameter for stock assessments. The need to establish age-specific natural mortality coefficients is widely recognized because M decreases rapidly over the early stages of the life cycle… read more here.
