Drivers of long-term invertebrate community stability in changing Swedish lakes. [PDF]
Glob Chang Biol, 2020 We assess the long‐term stability of invertebrate communities in 105 lakes in the Swedish “lakescape” by quantifying stability at the individual lake level as well as the environmental and physical variables affecting this stability at the ecoregion level.

Transcriptomics and differential gene expression in Whitmania pigra (Annelida: Clitellata: Hirudinida: Hirudinidae): Contrasting feeding and fasting modes. [PDF]
Ecol Evol, 2019 AbstractThe medicinal utility of leeches has been demonstrated through decades of use in modern hospital settings, mainly as relievers of venous congestion following flap or digit replantation surgery. In the present study, we sequence and annotate (through BLAST‐ and Gene Ontology‐based approaches) the salivary transcriptome of the nonblood feeding ...

Ecological indicators for qualitative assessment of Ojarud River: A case study
Ecology and Evolution, Volume 13, Issue 7, July 2023., 2023 The results of this study exposed a sizable alteration in the diversity and abundance of macro‐invertebrate from the sensitive families to resistant and tolerant taxa under the contamination stress resulting from the point source pollution in the Ojarud River.

Molecular Ecology, Volume 32, Issue 8, Page 2022-2040, April 2023., 2023 Abstract One of the most important physiological challenges animals had to overcome during terrestrialization (i.e., the transition from sea to land) was water loss, which alters their osmotic and hydric homeostasis. Aquaporins are a superfamily of membrane water transporters heavily involved in osmoregulatory processes.

Poly-paraphyly of Hirudinidae: many lineages of medicinal leeches [PDF]
BMC Evolutionary Biology, 2009 Medicinal leeches became infamous for their utility in bloodletting popularized in the 19th century, and have seen a recent resurgence in post-operative treatments for flap and replantation surgeries, and in terms of characterization of salivary anticoagulants.

New host and distribution record of Pontobdella macrothela (Schmarda, 1861) (Annelida, Hirudinea) from a Grey Reef Shark, Carcharhinus amblyrhynchos (Bleeker, 1856), in Mozambique, Western Indian Ocean [PDF]
Check List, 2019 This report describes the first record of the piscicolid leech Pontobdella macrothela from Mozambique waters and the first record of P. macrothela parasitizing a Grey Reef Shark (Carcharhinus amblyrhynchos). The leech, P.

Mechanics of cocoon secretion in a segmented worm (Annelida: Hirudinidae) [PDF]
Micron, 2016 Clitellate annelids (e.g., segmented earthworms, leeches) secrete proteinaceous cocoons into which eggs are deposited. The process of cocoon production is characterized by the coordinated release of micro-granules from secretory cells positioned asymmetrically within the clitellum.

Zoologica Scripta, Volume 49, Issue 5, Page 614-640, September 2020., 2020 Abstract Clitellata is a major clade of Annelida comprising nearly all freshwater and terrestrial annelids as well as several marine species. We investigated clitellate phylogenetic relationships using transcriptomes sampled from 74 taxa (64 clitellates and 10 polychaetes), including multiple representatives of nearly all major clitellate higher taxa ...
