A rapid cleaning method for diatoms
(Diatom Research, 2019-07-18)We describe here a protocol for cleaning diatoms when time is short and the amount of sample is very limited. Essentially, the method consists of drying material onto coverslips and cleaning it directly ... -
How far are we from providing pigs appropriate environmental enrichment?

Changing nutrients, changing rivers
(Science, 2019-08-16)Eutrophication—the excessive enrichment of a body of water with nutrients such as nitrogen (N) and phosphorus (P)—is Earth's most widespread problem for water quality (1, 2). Growing evidence suggests ... -
Tracking a mass mortality outbreak of pen shell Pinna nobilis populations: A collaborative effort of scientists and citizens
(Scientific Reports, 2019-09-16)A mass mortality event is devastating the populations of the endemic bivalve Pinna nobilis in the Mediterranean Sea from early autumn 2016. A newly described Haplosporidian endoparasite (Haplosporidium ... -
Dietary fatty acid profiling in plant protein‐rich diets affects the reproductive performance, egg fatty acid profile and haematological parameters in female rainbow trout (Oncorhynchus mykiss)
(Aquaculture Nutrition, 2019-05-03)The influence of dietary fish oil (FO) substitution with blends of vegetal oils (VO: canola, linseed, olive, sunflower, corn and coconut oils) in plant protein‐rich diets on reproductive performance and ... -
Diat.barcode, an open-access curated barcode library for diatoms
(Scientific Reports, 2019-10-22)Diatoms (Bacillariophyta) are ubiquitous microalgae which produce a siliceous exoskeleton and which make a major contribution to the productivity of oceans and freshwaters. They display a huge diversity, ... -
First results of phytoplankton spatial dynamics in two NW-Mediterranean bays from Chlorophyll-a estimates using Sentinel 2: potential implications for aquaculture
(Remote Sensing, 2019-07-25)Shellfish aquaculture has a major socioeconomic impact on coastal areas, thus it is necessary to develop support tools for its management. In this sense, phytoplankton monitoring is crucial, as it is ... -
Feeding pasteurized waste milk to preweaned dairy calves changes fecal and upper respiratory tract microbiota
(Frontiers in Veterinary Science, 2019-06-06)In the present study bacterial communities from both, the gastrointestinal and respiratory tract of pre-weaned dairy calves fed two different milk-feeding programs were characterized using 16S rRNA gene ... -
Pharmacokinetics of oral and subcutaneous meloxicam: Effect on indicators of pain and inflammation after knife castration in weaned beef calves
(PLoS ONE, 2019-05-24)Oral meloxicam is labelled for reducing pain and inflammation associated with castration in cattle in Canada, however, subcutaneous meloxicam is only labelled for pain associated with dis-budding and ... -
Discovery of a kleptoplastic 'dinotom' dinoflagellate and the unique nuclear dynamics of converting kleptoplastids to permanent plastids
(Scientific Reports, 2019-07-19)A monophyletic group of dinoflagellates, called ‘dinotoms’, are known to possess evolutionarily intermediate plastids derived from diatoms. The diatoms maintain their nuclei, mitochondria, and the ... -
Homothallism, morphology and phylogenetic position of a new species of Sellaphora (Bacillariophyta), S. pausariae
(Plant Ecology and Evolution, 2019-07-09)Background and aims – The eutrophic Blackford Pond in Edinburgh has already provided the holotypes of six other Sellaphora species. A further undescribed species is present and requires description and ... -
Eileen J. Cox: her journey with diatoms
(Plant Ecology and Evolution, 2019-07-09)Eileen already had a keen interest in science during her school years. She studied Botany at Bristol University from 1967–1970, and it was her University teacher, Professor Frank Round, who inspired her ... -
Drought decreases incorporation of recent plant photosynthate into soil food webs regardless of their trophic complexity
(Global Change Biology, 2019-07-13)Theory suggests that more complex food webs promote stability and can buffer the effects of perturbations, such as drought, on soil organisms and ecosystem functions. Here, we tested experimentally how ... -
Taxonomy and diversity of a little-known diatom genus Simonsenia (Bacillariaceae) in the marine littoral: novel taxa from the Yellow Sea and the Gulf of Mexico
(Plant Ecology and Evolution, 2019-07-09)Background and aims – The diatom genus Simonsenia has been considered for some time a minor taxon, limited in its distribution to fresh and slightly brackish waters. Recently, knowledge of its diversity ... -
Occurrence of tetrodotoxin in bivalves and gastropods from harvesting areas and other natural spaces in Spain
(Toxins, 2019-06-11)Tetrodotoxin (TTX) is a potent neurotoxin that is receiving increasing interest in the European Union because it has been found in different fishery products (fish, bivalves and gastropods) captured in ... -
