The effects of single versus successive warm summers on an intertidal community

open access: yesOikos, EarlyView.
To accurately predict how organisms and ecological communities will respond to future conditions caused by climate change, we must consider the temporal dynamics of environmental stressors, including the effects of repeated exposures to stress. We performed a two‐year passive thermal manipulation in coastal British Columbia, Canada to determine how ...

Effects of macrobenthos on sediment-water oxygen and ammonium fluxes. Final Report. [PDF]

open access: yes, 1997
Sediments are an important location in determining the fate of nutrients entering the estuary. Role of sediments needs to be incorporated into water quality models.

No aliens allowed: A narrative analysis of the blue crab (Callinectes sapidus) in the Lagoon of Venice (Northern Adriatic, Italy)

open access: yesPeople and Nature, EarlyView.
Abstract This study critically analyses the main narratives surrounding the Atlantic blue crab (Callinectes sapidus) in the Lagoon of Venice. We used a mixed‐method approach, performing a qualitative discourse analysis on a sample of 68 textual sources to identify the narratives across two sectors in the management of the case study: media and politics,

Temporal tracking of mineralization and transcriptional developments of shell formation during the early life history of pearl oyster Pinctada maxima [PDF]

open access: yes, 2011
Molluscan larval ontogeny is a highly conserved process comprising three principal developmental stages. A characteristic unique to each of these stages is shell design, termed prodissoconch I, prodissoconch II and dissoconch.

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

open access: yesPeople and Nature, EarlyView.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Morfometría de Sanguinolaria cruenta (Bivalvia: Psammobidae) en playa Tucacas, Falcón, Venezuela

open access: yesRevista de Biología Tropical, 2001
Se colectaron 312 conchas de S. cruenta con su ligamento en Playa Tucacas, Edo. Falcón, en mayo de 1999. A cada ejemplar se le midió: longitud antero-posterior, altura total, ancho, longitud anterior, altura dorsal, área de la valva y su peso.

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Biological performance of the penshell Atrina maura and mussel Mytella strigata under different water flow regimes

open access: yesCiencias Marinas, 2010
Three water flow rates (3.1, 7.3, and 12.1 cm s–1) were used during a 26-day period to determine their effects on shell dimensions, tissue mass, condition index, biochemical composition of tissues, and mortality of the penshell Atrina maura and mussel ...

Exploring the Impact of Polystyrene Microplastic Beads on Male Gonads of the Marine Mussel, Mytilus galloprovincialis

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Plastic, with its remarkable versatility and numerous applications, has greatly benefited humanity. However, its extreme resistance to natural degradation means it persists in the environment for long periods, causing global environmental problems.

Growth response of Heterobranchus longifilis fingerlings fed with varying levels of dietary freshwater mussel (Aspatharia sinuata) [PDF]

open access: yes, 2005
A common bivalve: Freshwater mussel, Aspatharia sinuate was evaluated as a dietary protein supplement in the production diet for Heterobranchus longifilis fingerlings with mean body weight 8.34 plus or minus 10g reared in aquaria tanks.
