Marine Invertebrate-Associated Bacteria In Coral Reef Ecosystems As A New Source Of Bioactive Compounds [PDF]

open access: yes, 2004
Coral reefs are the most species-rich environments in the oceans. Reefs cover 0.2% of the ocean’s area and yet they provide home to one-third of marine fishes and to tens of thousands of other species.

Trophodynamics features and potential human health risk of arsenic and cadmium in marine fauna from the Yellow River Estuary, China

open access: yesEcological Indicators, 2023
Toxic arsenic (As) and cadmium (Cd) pollution threatens organisms and humans in coastal ecosystems, but their biomagnification in marine systems remains under debate.

Exposure of benthic invertebrates to sediment vibration: From laboratory experiments to outdoor simulated pile-driving [PDF]

open access: yes
Activities directly interacting with the seabed, such as pile-driving, can produce vibrations that have the potential to impact benthic invertebrates within their vicinity.

Increased use of intertidal resources benefits breeding success in a generalist gull species [PDF]

open access: yes, 2017
Determining how resource use impacts on a species’ demography is important, especially in habitats which are being altered by anthropogenic land-use change. If changes result in species consuming resources of reduced quality their demographic traits may

The role of transposable elements in the evolution of non-mammalian vertebrates and invertebrates [PDF]

open access: yesGenome Biology 2010, 11:R59, 2010
Background: Transposable elements (TEs) have played an important role in the diversification and enrichment of mammalian transcriptomes through various mechanisms such as exonization and intronization (the birth of new exons/introns from previously intronic/exonic sequences, respectively), and insertion into first and last exons.

The effects of changing climate on faunal depth distributions determine winners and losers

open access: yes, 2014
Changing climate is predicted to impact all depths of the global oceans, yet projections of range shifts in marine faunal distributions in response to changing climate seldom evaluate potential shifts in depth distribution.

Bioactivity and Biotechnological Overview of Naturally Occurring Compounds from the Dinoflagellate Family Symbiodiniaceae: A Systematic Review

open access: yesThe Scientific World Journal, 2021
Marine invertebrates are a significant source of biologically active compounds. Recent studies have highlighted the role of microbiota associated with marine invertebrates in the production of bioactive compounds.

Trophic signatures of marine organisms in the Mediterranean as compared with other ecosystems [PDF]

open access: yes, 2004
We compared several large marine ecosystems in terms of species numbers of fishes, sea birds, marine mammals, and cephalopods. We examined how these numbers were distributed by trophic level, from herbivores to top predators.

Photoreception in Marine Invertebrates [PDF]

open access: yesAmerican Zoologist, 1986
SYNOPSIS. In order for photoperiodic phenomena to be expressed by any animal, the organism must possess some sort of photoreceptor. This may be in the form of an eye or an extraocular receptor, and the invertebrate phyla illustrate fantastic diversity in design of either receptor type. While all the major invertebrate phyla possess photoreceptor organs
