Multiple-locus heterozygosity, physiology and growth at two different stages in the life cycle of the Chilean oyster Ostrea chilensis [PDF]

open access: yes, 1996
A random sample of 150 individuals of a laboratory-produced cohort of Ostrea chilensis Philippi, 1845 was taken at 10 and 36 mo of age to estimate physiological variables and individual heterozygosity using 4 loci (Lap, Pgi, Pgm and Ca).

A global estimator of C and N isotope baselines for fresh waters

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Baselines are the pebbles in the shoes of isotope ecologists. The extreme variability of the isotope composition of resources at the base of food webs governs the spatial differences of consumers' isotope composition, so that isotope‐inferred trophic properties can be compared across ecosystems only after correction for baseline effects ...

Long‐read sequencing for biodiversity analyses—A comprehensive guide

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract DNA‐based monitoring of biodiversity has revolutionised our ability to describe communities and rapidly assess anthropogenic impacts on biodiversity. Currently established molecular methods for biomonitoring rely heavily on classic metabarcoding utilising short reads, mostly through Illumina data.

Bivalve immune responses and climate changes: is there a relationship? [PDF]

open access: yesInvertebrate Survival Journal, 2011
Global climate changes (GCCs) are predicted to occur in the next hundred years through increases in temperature, water acidification and changes in seawater salinity. Increasing atmospheric CO2 concentrations are considered to be the main responsible for

Ecological studies of the aquatic soil invertebrates in three inundation forests of Central Amazonia

open access: yes, 1975
From January 1971 till August 1972 ecological studies were carried out on the aquatic macroinvertebrates of the benthos community of three Central-Amazonian inundation forests.

Multi‐barcoding‐based species identification using a hierarchical attention network with staged curriculum learning

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

Eels as Hosts for Parasitic Mussels: The Importance of Endangered Species Co‐Management

open access: yesAnimal Conservation, EarlyView.
The ability of Unionid mussels to utilize eels as hosts has not been investigated thoroughly, particularly in Europe; therefore, we investigated the transformation success of Europe's seven most common unionid species after infestation on the European eel (Anguilla anguilla).

Paralytic Shellfish Toxin Extraction from Bivalve Meat for Analysis Using Potentiometric Chemical Sensors

open access: yesBiosensors
A simple and reliable methodology for the detection of paralytic shellfish toxins (PSTs) in bivalve tissues using potentiometric chemical sensors was developed.

Molecular and Biochemical Methods Useful for the Epigenetic Characterization of Chromatin-Associated Proteins in Bivalve Molluscs

open access: yesFrontiers in Physiology, 2017
Bivalve molluscs constitute a ubiquitous taxonomic group playing key functions in virtually all ecosystems, and encompassing critical commercial relevance.

Integrated Species Distribution Model Using Historical Data Shows Decline in a Common Semi‐Aquatic Mammal

open access: yesAnimal Conservation, EarlyView.
A diagram of the integrated species distribution model of river otter intensity of use. Three types of data (latrine detections, roadkill detections, and detection/nondetection surveys) are linked by different observation processes to the same underlying intensity of use.
