If triclads are better than leeches at exploiting damaged prey, this could be a mechanism for their coexistence. 2. Laboratory experiments investigated the comparative speeds at which leeches and triclads responded to crushed prey. Young and adult predators were offered a crushed specimen of the ...
One of the leeches was of record size (77.7 mm total length); another specimen measuring 64.4 mm had 153 brood-sized (x = 4.5 mm) young attached to its venter. Because of poor visibility and partial ice cover, only 7 turtles were recovered in March 1996. All of these turtles had ...
medicinalis; this confusion also prompted the designation of a neotype specimen for H. medicinalis in order to ameliorate future taxonomic confusion9. The utility of leeches in modern medicine focuses on post-surgical procedures, chiefly following digit replantation or skin grafting surgery10,11 ...
The first species identified from North America () was not fully described but, based on the collection of a specimen from the same site, . was subsequently thought to have three annuli between the gonopores. The syntypes of . were examined. One was identified as and the second as a ...
Here we present a specimen of the leech Erpobdella punctata, in which the gonopores have been duplicated and the male and female reproductive tracts are out of register between the left and right sides of the body. To confirm the identity of the specimen, we use a phylogenetic approach ...
The first specimen of the species I ever saw was found by me in Bala Lake, on the 22nd of June last ; it was attached (more Glossiphoniarum) to the under surface of a stone near the margin of the lake, with a number of yellow eggs underneath it. The only other locality in which...
The species had been collected rarely in the northeastern United States, with only seven specimens collected during the 20th century and the original type specimen(s) lost. The recent South Carolina collections add three locality records and nine specimens, and two other specimens that had been ...
K + disappearance from the vacuole was not affected by ouabain, but a decrease in specimen temperature decreased the rate constant of K + clearing, which has a Q 10 of 1.48. It is concluded that K + clearing from the vacuole is dominated by passive processes, and that the Na + /K +...
The mean concentration of anti-thrombin units in each specimen of M. decora and H. medicinalis is 100 and 285 AT-U, respectively. These findings support the concept that H. medicinalis is more advanced in terms of haematophagous predation. Despite similar feeding durations by both species of...
