“…Ballocephala verrucospora Richardson, has been reported attacking M. hufelandi collected in Finland (Hallas, ), and unidentified tardigrades from Scotland, Wales (UK; Richardson, ) and Japan (Morgan, ; Saikawa & Oyama, ). Lastly, Ballocephala sphaerospora Drechsler, was found on unidentified tardigrade species collected in Pennsylvania, USA (Drechsler, ) and Japan (Glockling & Yamada, ). Zygospores of Ballocephala are most probably the so‐called X‐bodies found in the bodies of the tardigrades H. dujardini , Adropion scoticum Murray, 1905, and Dactylobiotus dispar Murray, 1907 (see Hallas, ; Van Rompu & De Smet, ; Van Rompu, De Smet & Bafort, ).…”

Interspecific relationships of tardigrades with bacteria, fungi and protozoans, with a focus on the phylogenetic position ofPyxidium tardigradum(Ciliophora)

Symbiosis can be defined as an interaction between individuals of different biological species. Despite the small number of studies solely devoted to symbiotic interactions between tardigrades and micro-organisms (such as bacteria, fungi and protozoans), numerous reports can be found in the literature, especially as notes in faunal and alpha-taxonomy studies. Here, we review the literature and compile a list of the interactions between tardigrades and micro-organisms, excluding those that constitute food for tardigrades. Furthermore, a genetic study on a tardigrade symbiophoront, the ciliate Pyxidium tardigradum van der Land, 1964 was performed. There are a few records of P. tardigradum on both European and Asian tardigrades, but no morphological discrepancies among populations have been observed. We present here the phylogenetic positioning for P. tardigradum inferred by using nuclear ribosomal markers (18S and 5.8S). The phylogenetic trees showed all P. tardigradum specimens grouped together, and belonging to the family Operculariidae, order Operculariida. Moreover, a study based on the genetic distances between a Portuguese and an Irish population of P. tardigradum was performed using internal transcribed spacers ITS1 and ITS2. The ITS1 and ITS2 sequences showed differences between populations, leading us to hypothesize the presence of cryptic species.

“…Therefore, the movement of rabbits between subregions would not affect the results of the surveys conducted over 2 years. In addition, Sugimura (1998) estimated that the latrines stayed on the survey routes for 26 days on average, before heavy rains flushed them away or dung beetles and fungi broke them down ( Sugimura, 1987; Tsukamoto, 1989; Glockling & Yamada, 1997).…”

The Amami rabbit Pentalagus furnessi is a rare forest‐dwelling form endemic to the Amami and Tokuno Islands in Japan. In order to estimate the distribution and abundance of the Amami rabbit we counted their faecal pellets along forest roads and streams as well as within the forests on Amami and Tokuno Islands during January 1993–March 1995. The number of pellets/km along a stream gave a practical index for measuring relative abundance. The rabbit was estimated to be distributed over about 370 sq km on Amami Island and 33 sq km on Tokuno Island. There was a large variance in faecal abundance among the survey routes. Some populations were completely isolated and thought to be very small. The size of a local population was positively correlated with those of neighbouring populations and the amount of mature forest relative to other seral stages. We compared the results of this survey with those of previous surveys to find that the total population of this species appears to be declining. Some conservation measures are proposed for forest habitat management, designed to avert the decline of the Amami rabbit and to ensure its preservation.

“…An Anoplocepalidae cestode (3/3) and a trematode, Ogmocotyle, were recorded (1/3) in the small intestine (Kamiya et al 1987a). Dung of the Amami rabbit harbors 16 species of fungi, which kill nematodes, rotifers, and microscopic animals (Glockling 1998;Glockling and Yamada 1997;Zare and Gams 2001).…”
