Reproductive Strategies of Erpobdella punctata (Hirudinoidea) in Two Temporary Ponds
Oikos, 1977The reproductive strategies of Erpobdella punctata (Leidy) were studied in two limnologically similar temporary ponds in Alberta. In Cairn Pond, E. punctata was the dominant erpobdellid, but in Jail Pond Nephelopsis obscura Verrill was dominant. In Jail Pond, E.

Specialized pelagic feeding by Erpobdella montezuma (Hirudinea)
Ecography, 1987 The pelagic amphipod, Hyalella montezuma comprised nearly 90% of the diet of the leech, Erpobdella montezuma in the near thermally constant environment of Montezuma Well, Arizona.

Relationship between neurosecretion and spermatogenesis in the leech, Erpobdella lineata
Comparative Biochemistry and Physiology Part A: Physiology, 1986Abstract 1. 1. The central nervous system in the leech, Erpobdella lineata, consists of 21 pairs of cell compartments. 2. 2.AF (aldehyde fuchsin) positive α-cells were observed in the buccal ganglion, cell compartment 8 or 9 and the subesophageal ganglion, cell compartment 11. 3. 3.

During the study of the anatomy of mature Nephelopsis obscura and Erpobdella punctata the structure and distribution of the male and female reproductive organs were observed. The gonopores in N. obscura and E. punctata were separated by one and two annuli, respectively. In N. obscura, the multifollicular testes lie in two lateral columns in the form of

Mitochondrial DNA Part A, 2014
Erpobdella octoculata (Linnaeus, 1758; Hirudinea: Arhynchobdellida: Erpobdellidae) is a very common and morphologically variable macrophagous predators of aquatic invertebrates. Here we determined the complete mitochondrial DNA (mtDNA) sequence of this species, as the first representative of the suborder Erpobdelliformes.

American Midland Naturalist, 1970
The life history, fecundity, behavior and feeding habits of the North American leech, Erpobdella punctata, are investigated. There is evidence of an upstream migration in early spring. The size distribution within populations indicates that growth to maturity took one year in a permanent pond, but two years in a stream, perhaps because the stream dried

Zoomorphology, 2001
In early developmental stages of Erpobdella octoculata two pairs of transitory nephridia occur which degenerate during the formation of the body segments. Because in the ground pattern of Annelida the first nephridia formed during ontogenesis are protonephridia, it can be assumed that the transitory nephridia of E.
