Illinois Natural History Survey Bulletin, 1901 This paper is a partial descriptive catalogue of the leech fauna of Illinois. It is founded on collections gathered from time to time during the past twenty-five years by the Illinois State Laboratory under the direction of Prof. S. A. Forbes, ofwhich material by far the most important part, as regards both number of species and individuals and state ...

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 ...

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.

Hirudinea as Human Parasites in Palestine [PDF]
Parasitology, 1908 Leeches are common in the fountains and pools of Palestine, particularly in the northern parts, known to us familiarly as ‘Galilee,’ and further north in the district of the Lebanon. In the later summer and autumn months they are so plentiful in places that almost every horse and mule passing through these parts has a bleeding mouth.

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
