Human Activity as a Growing Threat to Marine Ecosystems: Plastic and Temperature Effects on the Sponge Sarcotragus spinosulus

Toxics
Human activities increasingly threaten marine ecosystems through rising waste and temperatures. This study investigated the role of plastics as vectors for Vibrio bacteria and the effects of temperature on the marine sponge Sarcotragus spinosulus ...

Phylogenomic analysis of ultraconserved elements clarifies relationships and morphological evolution in Cryptoplacoidea (Mollusca: Polyplacophora)

Cladistics, EarlyView.
Abstract Targeted enrichment of ultraconserved elements (UCEs) is a powerful tool for resolving phylogeny in groups with limited morphological or molecular data. Here, we use UCEs to reconstruct the first comprehensive phylogeny of the chiton superfamily Cryptoplacoidea, including museum material up to 133 years old.

Haloperoxidase from five marine sponges (demospongia) collected from China Sea

, 2008
Thousands of organohalogen compounds have been found in marine and terrestrial organisms (Gribble, 1999). Many of these halogenated natural products have biological activities, such as antibacterial, antifungal, antiviral, and anti-inflammatory ...

Advancing conservation breeding programs for marine invertebrates

Conservation 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.

Marine sponges : forty-six sponges of northern New Zealand

, 1984
Sponges are invertebrates and form the only phylum, Porifera, in the subkingdom Parazoa. They are the most primitive of multicellular animals, having neither true tissues nor organs, with the cells showing considerable independence from one another.

Marine rewilding principles as a guiding framework for large‐scale ecosystem restoration

Conservation Science and Practice, EarlyView.
As marine ecosystems face accelerating degradation from human pressures, interest is growing in approaches that move beyond protection toward active recovery of ecological processes. This article introduces marine rewilding as a forward‐looking framework and synthesizes ecological and social science to develop eight transdisciplinary principles that ...

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Bioactive potential of Streptomyces against fish and shellfish pathogens

Iranian Journal of Microbiology, 2010
Background and Objectives: In the present study, isolation of Streptomyces associated with marine sponges and its bioactive potential against fish and shellfish pathogens were assessed. The Streptomyces sp.

Tracking hatchery and wild Atlantic salmon (Salmo salar) smolt during river exit and early marine migration to assess survival, predation risk and migration speed

Journal of Fish Biology, EarlyView.
Abstract Significant declines in Atlantic salmon (Salmo salar) populations across their range have prompted an increased use of hatchery supplementation programmes to support population recovery. However, concerns persist regarding the effectiveness of these programmes due to limited understanding of how hatchery‐reared salmon perform post‐release in ...
