Predators and resources influence phosphorus transfer along an invertebrate food web through changes in prey behaviour. [PDF]

open access: yesPLoS ONE, 2013
Predators play a fundamental role in prey trophic behaviour, with indirect consequences for species coexistence and ecosystem functioning. Resource quality and availability also influence prey trophic behaviour, with potential effects on predator-prey ...

Phylogenomic analyses reveal a Palaeozoic radiation and support a freshwater origin for clitellate annelids

open access: yesZoologica 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 ...

Anthropogenic flow intermittency shapes food‐web topology and community delineation in Mediterranean rivers

open access: yesInternational Review of Hydrobiology, Volume 105, Issue 3-4, Page 74-84, June 2020., 2020
Abstract Anthropogenic flow intermittency is considered a severe disturbance for benthic macroinvertebrates with largely unknown impacts on the organization of benthic communities and their food webs. We analysed the community composition (as taxonomic composition and relative abundance of taxa) and food webs of the macroinvertebrates inhabiting the ...

Developmentally regulated multisensory integration for prey localization in the medicinal leech [PDF]

open access: yes, 2011
Medicinal leeches, like many aquatic animals, use water disturbances to localize their prey, so they need to be able to determine if a wave disturbance is created by prey or by another source.

First Records of Potamic Leech Fauna of Eastern Siberia, Russia

open access: yesDataset Papers in Science, Volume 2013, Issue 1, 2013., 2013
We studied the fauna of leech and leech‐like species inhabiting main water streams of Eastern Siberia and its tributaries, which are attributed to Lake Baikal basin and Lena River basin. Here we present their list for the first time. This study was mainly aimed for free‐living parasitic and carnivorous leeches whereas piscine parasites were not ...
