Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea

Journal of Fish Biology, EarlyView.
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

Lake sturgeon (Acipenser fulvescens) growth and longevity estimated from adult capture–mark–recapture data

Journal of Fish Biology, EarlyView.
Abstract Effective fishery management policy depends on accurate life‐history data, particularly for harvested species. Longevity is a core life‐history trait that is directly related to annual survival and lifetime reproductive potential, but fish longevity is generally not well documented, particularly for long‐lived species.

Peri‐implantitis—Is it mainly a clinician‐initiated complication of implant therapy?

Periodontology 2000, EarlyView.
Abstract Aim The high prevalence of peri‐implantitis is concerning, with a growing consensus that the majority of cases are complications initiated by clinician‐related errors rather than classic pathology. A primary predisposing factor for peri‐implantitis is exposure of the micro‐rough implant surfaces to the peri‐implant sulcus after treatment ...
