Assessing the degradation of environmental DNA and RNA based on genomic origin in a metabarcoding context

open access: yesEnvironmental DNA, Volume 5, Issue 5, Page 1016-1031, September 2023., 2023
This article highlights the utility and limitations of environmental nucleic acid‐based metabarcoding in accurately quantifying decay rates using two barcode markers targeting Arthropoda taxa. We demonstrate the need for further comparative studies using both metabarcoding and single‐species detection methods to assess the persistence and degradation ...

Biofloc technology as part of a sustainable aquaculture system: A review on the status and innovations for its expansion

open access: yesAquaculture, Fish and Fisheries, Volume 3, Issue 4, Page 331-352, August 2023., 2023
This paper is a review paper based on biofloc technology (BFT). In this paper the current global status of BFT, the biology behind the technique and areas for future expansion are discussed. Abstract Increased food demand, reflecting a rising global human population, attaining 8 billion in 2022, has furthered the intensification of farmed aquatic ...

Spinicaudata (Branchiopoda: Diplostraca) in Australia’s arid zone: unparalleled diversity at regional scales and within water bodies [PDF]

open access: yesJournal of Crustacean Biology, 2015
Multispecies spinicaudatan assemblages, where several species co-occur simultaneously within the same water body, are relatively rarely observed. In part, this can be due to taxonomic impediments and the presence of cryptic species. Several recent studies on Australian Spinicaudata revealed much higher species diversities than previously known for this

Assessment of listing and categorisation of animal diseases within the framework of the Animal Health Law (Regulation (EU) No 2016/429): infectious pancreatic necrosis (IPN)

open access: yesEFSA Journal, Volume 21, Issue 6, June 2023., 2023
Abstract Infectious pancreatic necrosis (IPN) was assessed according to the criteria of the Animal Health Law (AHL), in particular, the criteria of Article 7 on disease profile and impacts, Article 5 on its eligibility to be listed, Annex IV for its categorisation according to disease prevention and control rules as in Article 9, and Article 8 for ...

Unintended changes in transgenic maize cause no nontarget effects

open access: yesPLANTS, PEOPLE, PLANET, Volume 4, Issue 4, Page 392-402, July 2022., 2022
Genetic engineering is used to introduce new genes into plants to obtain crops with novel traits. However, the unintended effects of genetically engineered (GE) crops on nontarget organisms—such as beneficial insects—are a topic of much concern.

TransPi—a comprehensive TRanscriptome ANalysiS PIpeline for de novo transcriptome assembly

open access: yesMolecular Ecology Resources, Volume 22, Issue 5, Page 2070-2086, July 2022., 2022
Abstract The use of RNA sequencing (RNA‐Seq) data and the generation of de novo transcriptome assemblies have been pivotal for studies in ecology and evolution. This is especially true for nonmodel organisms, where no genome information is available.

DNA metabarcoding quantifies the relative biomass of arthropod taxa in songbird diets: Validation with camera‐recorded diets

open access: yesEcology and Evolution, Volume 12, Issue 5, May 2022., 2022
This study is a field‐based validation of the application of DNA metabarcoding to quantitatively assess diets of wild‐living songbirds in temperate woodland ecosystems. The average relative read abundance of arthropod orders in fecal samples matched the scaled biomass contribution of these orders as observed on nestbox cameras.

Reassignment of Lioestheria codoensis Cardoso (Spinicaudata, Anthronestheriidae) from the Lower Cretaceous of Brazil: systematics and paleoecology [PDF]

open access: yes, 2013
 Lioestheria codoensis Cardoso was described from materials originally collected from the Codó Formation (Lower Cretaceous, Parnaíba Basin, Piauí State), northeastern Brazil. Since its discovery L.

Biological aspects of the Spinicaudata (Branchiopoda, Diplostraca) in the largest alluvial wetland in Croatia [PDF]

open access: yesCrustaceana, 2006
Lonjsko Polje (Croatia) is among the largest alluvial wetlands in Europe. Temporary ponds that are the natural habitat for spinicaudatan branchiopods are very abundant in the area. We determined the time of occurrence, length of the life span, and the sexual structure and habitat characteristics of populations of Spinicaudata.

Morphological defences and defence–cost trade‐offs in Daphnia in response to two co‐occurring invertebrate predators

open access: yesFreshwater Biology, Volume 67, Issue 5, Page 883-892, May 2022., 2022
Abstract Inducible morphological defences are crucial for understanding predator–prey interactions. Such defences have been mostly studied in a single‐predator context, ignoring the fact that prey organisms are often exposed to multiple predators. In deep peri‐Alpine European lakes, the keystone grazer Daphnia coexists with two cladoceran predators ...
