Members of the freshwater family Erpobdellidae, such as the popular bait leech Nephelopsis obscura, are carnivorous on other oligochaetes (Klemm, 1972). Haemopis species, a group that is closely related to the sanguivorous medicinal leeches, also are predaceous and many have large teeth for shredding prey as they are ingested.

Background. Although semelparity is a life history characterized by a single reproductive episode within a single reproductive season, some semelparous organisms facultatively express a second bout of reproduction, either in a subsequent season (“facultative iteroparity”) or later within the same season as the primary bout (“secondary reproduction”).

Description: Founded in 1932, Journal of Animal Ecology publishes original research papers on all aspects of animal ecology; specifically those that make substantial contributions to our understanding of animal ecology as well as offering insights into issues of general interest to ecologists. This includes reviews that shed light on subjects central to animal ecology, including theoretical.

Glyphosate-based herbicides (GBHs) are chemicals developed to control unwanted plants such as weeds or algae. These chemicals act on EPSPS enzyme that blocks the production of tyrosine, phenylalanine, and tryptophan amino acids causing plant death. This biochemical pathway exists only in plant organisms. Despite the target use, GBHs have been related to toxic effects on nonplant organisms.

Of 20 species of Hirudinea collected in Colorado, USA, 12 were new to the state. Helobdella stagnalis was the most abundant and widely distributed. Erpobdella punctata, Haemopis marmorata, Glossiphonia complanata, Placobdella ornata and Theromyzon rude were also widespread. Batracobdella phalera and B. picta occurred in the western half of the state in foothill and mountain zones.
