A new checklist of Slovenian leeches (Hirudinea: Euhirudinea): In memory of Boris Sket (1936–2023)

Natura Sloveniae, 2023
The new (as of 2023) checklist of Slovenian leeches (Euhirudinea) contains 33 species, which represents a 44% increase since the last published inventory in 2003.

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

Molecular Ecology, Volume 34, Issue 22, November 2025.
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.

Redescription of Placobdella Multistriata ( Johansson, 1909) (Hirudinea: Glossiphoniidae)

Koedoe: African Protected Area Conservation and Science, 1979
Study of a large number of specimens of Placobdella multistriata (Johansson, 1909) revealed the unsatisfactory nature of the information currently available on this leech. The reason is evidently the fact that previous workers had very limited and poorly

Restoration using flow deflectors: a question of fine‐scale spatial layout in headwater stream beds

Restoration Ecology, Volume 33, Issue 7, September 2025.
Current European Union objectives for 2030 aim to restore ecosystems to halt biodiversity loss. Here, we studied the consequences of headwater stream restoration by placing large wood in the streambed to act as flow deflectors. We hypothesized that these flow deflectors would create a fine‐scale spatial arrangement of habitats, fostering a diverse and ...

Postcranial anomalies of Eocene freshwater pleurodiran and cryptodiran turtles from the Spanish Duero Basin

The Anatomical Record, Volume 308, Issue 6, Page 1659-1676, June 2025.
Abstract Testudines are one of the best‐represented taxonomic groups among the Paleogene taxa of the Duero Basin (Castile and Leon Autonomous Community, central Spain). Among them, Neochelys (Podocnemidide) and Allaeochelys (Carettochelyidae) are most abundant, allowing the population to be assessed for osteological anomalies.

Investigating changes to food web structure after fish removal using size spectra analysis

Ecosphere, Volume 16, Issue 5, May 2025.
Abstract Biomanipulation can control eutrophication, but if there is no discernible change, it is difficult to disentangle whether the biomanipulation failed to substantially alter food web structure or was unable to overcome external nutrient loading. Traditional food web model analyses to monitor management interventions can be prohibitively time and

Metazoan parasites of Geophagus brasiliensis (Perciformes: Cichlidae) in Patos lagoon, extreme south of Brazil

Revista Brasileira de Parasitologia Veterinária
This study has evaluated the parasitic fauna of 79 pearl cichlids (Geophagus brasiliensis) from the estuary of Patos Lagoon (31° 57' S and 52° 06' W), Rio Grande do Sul, Brazil, during the months of May and June in 2011 and 2012.

Capture—Incubate—Release: An Animal‐Friendly Approach to Assess Local Aquatic Macroinvertebrate Species Diversity Through Environmental DNA Metabarcoding

Environmental DNA, Volume 7, Issue 3, May–June 2025.
We assessed whether we can combine the advantages of both bulk and eDNA metabarcoding, that is, obtaining a local signal and being minimally invasive, to improve local invertebrate detections in streams using water samples. We quantified eDNA release over time after a short incubation in water for single species using qPCR and for bulk samples using ...
