Pleistocene to Holocene continuity and discontinuity in California Northern Channel Island marine invertebrate communities

open access: yesQuaternary Science Advances
There is growing interest in analyzing interdisciplinary datasets to better understand the evolution of ecosystems through deep time. One burgeoning area has been the integration of archaeological and fossil data to evaluate the long-term structure and ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Long‐term trends in parasite diversity and infection levels: approaches and patterns

open access: yesBiological Reviews, EarlyView.
ABSTRACT Parasites exist in every ecosystem, affecting nearly all organisms and playing a complex role in human societies. On the one hand, they contribute substantially to biodiversity and support ecosystem stability by performing essential ecological functions.

The spread of non‐native species

open access: yesBiological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Advancing aquatic biodiversity assessments of invertebrates using eDNA metabarcoding: A systematic evaluation of primers for marine and freshwater communities

open access: yesMethods in Ecology and Evolution
Invertebrate richness and community composition are key indicators of aquatic ecosystem health. Compared with morphotaxonomy‐based survey methods, DNA metabarcoding is a highly efficient and scalable biomonitoring approach that has become increasingly ...

Studies on Marine Invertebrate Collagens-IV

open access: yesNIPPON SUISAN GAKKAISHI, 1969
Acid soluble cuticle collagens were prepared from some marine worms, Neanthes diversicolor, Marphysa sanguinea, and Lumbriconereis heteropoda, of Polychaeta. These cuticle collagens exhibited a number of anomalous properties as compared with ordinary collagens. The cuticle collagen solution of N.

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Sentience in cephalopod molluscs: an updated assessment

open access: yesBiological Reviews, EarlyView.
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
