Higher alpha and gamma, but not beta diversity in tropical than in Mediterranean temporary ponds: A multi‐taxon spatiotemporal approach

open access: yesLimnology and Oceanography, Volume 68, Issue 10, Page 2402-2414, October 2023., 2023
Abstract The latitudinal diversity gradient predicts that tropical regions should have higher alpha, beta, and gamma diversity than temperate areas. However, only a few studies have assessed the temporal variability of the different components of diversity across climatic regions.

Under‐ice plankton community response to snow removal experiment in bog lake

open access: yesLimnology and Oceanography, Volume 68, Issue 5, Page 1001-1018, May 2023., 2023
Abstract Although previously overlooked, winter is now seen as a period of significant biological activity in the annual cycle of north‐temperate lakes. Research suggests a future of reduced ice cover duration and altered snow conditions could significantly change the functioning of aquatic ecosystems.

From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids. [PDF]

open access: yesMol Ecol
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.

An evaluation of crustacean and rotifer diversity and composition in a temporary pond metacommunity: Comparing results from field samples and a hatching experiment

open access: yesFreshwater Biology, Volume 68, Issue 3, Page 378-390, March 2023., 2023
Abstract Many aquatic invertebrates that inhabit temporary ponds produce resting forms to overcome the dry period, building up the egg bank. When the wet phase returns, the resting forms hatch and the community is restored, and then pioneer species may have a major influence on how the pond community will assemble. We aimed to evaluate the diversity of

Transcriptome data reveal Syndermatan relationships and suggest the evolution of endoparasitism in Acanthocephala via an epizoic stage.

open access: yesPLoS ONE, 2014
The taxon Syndermata comprises the biologically interesting wheel animals ("Rotifera": Bdelloidea + Monogononta + Seisonidea) and thorny-headed worms (Acanthocephala), and is central for testing superordinate phylogenetic hypotheses (Platyzoa, Gnathifera)

Fine structure of the retrocerebral organ in the rotifer Trichocerca similis (Monogononta)

open access: yesInvertebrate Biology, Volume 142, Issue 1, March 2023., 2023
Abstract The retrocerebral organ (RCO) is a complex glandular system that is widely distributed across species of phylum Rotifera (sensu stricto). This system is hypothesized to secrete mucus that aids in benthic locomotion, adhesion, and/or reproduction.

EST based phylogenomics of Syndermata questions monophyly of Eurotatoria

open access: yesBMC Evolutionary Biology, 2008
Background The metazoan taxon Syndermata comprising Rotifera (in the classical sense of Monogononta+Bdelloidea+Seisonidea) and Acanthocephala has raised several hypotheses connected to the phylogeny of these animal groups and the included subtaxa.

Extremely high abundances of Prasiola crispa-associated micrometazoans in East Antarctica

open access: yesPolar Research, 2022
To elucidate poorly known aspects of the microscopic metazoan distribution in ice-free parts of the Antarctic, we examined samples of the multicellular terrestrial alga Prasiola crispa, collected over the last decade in different parts of continental ...

Feeding habits and multifunctional classification of soil‐associated consumers from protists to vertebrates

open access: yesBiological Reviews, Volume 97, Issue 3, Page 1057-1117, June 2022., 2022
ABSTRACT Soil organisms drive major ecosystem functions by mineralising carbon and releasing nutrients during decomposition processes, which supports plant growth, aboveground biodiversity and, ultimately, human nutrition. Soil ecologists often operate with functional groups to infer the effects of individual taxa on ecosystem functions and services ...

Dispersal of pollen and invertebrates by wind in contrasting Arctic habitats of Svalbard [PDF]

open access: yesPolish Polar Research, 2023
Although Svalbard archipelago is considered as a natural laboratory for the environmental studies in the High Arctic, the knowledge on the transport and diversity of bioaerosols (aeroplankton) in the atmosphere is poorly recognized.
