Lifecycle, culture, and maintenance of the emerging cephalopod models Euprymna berryi and Euprymna morsei

open access: yesFrontiers in Marine Science, 2022
Cephalopod research remains limited by the inability to culture species under laboratory conditions for multiple generations to provide continuous access to animals at all stages of the life cycle.

Must Longtermists Wish Us All Dead? A Quadrilemma

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Longtermists assign great moral importance to making the long‐term future as good as possible, especially by ensuring the survival of humanity. We argue, to the contrary, that on assumptions that are plausible, conservative, or shared by leading longtermists, human extinction will likely augment total utility among human and non‐human animals ...

Improving Demographics and Conservation of Fishes Through Multi‐Frame Individual Distinctions by Size (MIDS)

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
MIDS (Multi‐frame Individual Distinctions by Size) is a new software package for improving how fish populations are assessed using stereo‐video data. By using the length, error and statistical inference of measurements, MIDS distinguishes individuals across multiple video frames and autonomously removes repeat observations, regardless of when the ...

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

open access: yesIntegrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

Absence of a Hectocotylus and Associated Mating Behaviour in the Paintpot Cuttlefish Ascarosepion tullbergi

open access: yesActa Zoologica, EarlyView.
ABSTRACT A hectocotylus is a sexually modified arm used by males of some cephalopod species to transfer spermatophores to females. In most cuttlefish (Sepiidae), it corresponds to the left arm IV, in which basal suckers are reduced or absent; this modification is thought to facilitate sperm transfer without premature rupture, which could be caused by ...

Cephalopod Ink: Production, Chemistry, Functions and Applications

open access: yesMarine Drugs, 2014
One of the most distinctive and defining features of coleoid cephalopods—squid, cuttlefish and octopus—is their inking behavior. Their ink, which is blackened by melanin, but also contains other constituents, has been used by humans in various ways for ...

Advancing conservation breeding programs for marine invertebrates

open access: yesConservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.
