“…The talitrid amphipods, however, have achieved a significant presence on land, at least in the southern hemisphere, and have extended their range into summer dry areas (Friend, 1982), despite an apparent lack of major morphological adaptations.…”

Water uptake and loss via the urosome in terrestrial talitrid amphipods (Crustacea: Amphipoda)

The amount of exosomatic water in the ventral channel can be controlled by uptake and loss via the urosome in simplidactylate and cuspidactylate landhoppers, palustral talitrids and beachfleas, but not apparently by sandhoppers. Both water uptake and loss involve deliberate dabbing of the uropod tips (uropods 1 and 2 in simplidactylate landhoppers and palustral talitrids, uropod 3 in cuspidactylate landhoppers and beachfleas) on to a wet or dry substratum. Water flows rapidly into, or out of, the central channel via capillary spaces between the body parts. Transfer of water forward from the abdomen to thorax is apparently facilitated by the beating of the pleopods, or, in those species with highly reduced pleopods, by the elongate distal lobe of the peraeopod 6 gill, which lies between the bases of peraeopod 7 and the first abdominal epimeron. Water also pools beneath the telson and is taken into the gut by anal drinking in all the species observed. These observations suggest that landhoppers, beachfleas and palustral talitrids take up water from the substratum using a mechanism analogous to that used by the terrestrial oniscoid isopods. Sandhoppers probably do not use this mechanism, since the morphology of their urosome reflects the selective pressures of their sandburrowing way of life.

“…Thus, at present, we recognize only two named species in Paciforchestia. In addition, Morino (1991) (2) propodus of male and female gnathopod 1 with longitudinal row of sheathed spines on lateral surface; (3) pereopods 3-7 each with moderately large dista1 spine on dactyl hinge; and (4) peduncle of uropod 3 very deep, These Taiwanese specimens are more similar to P. nvatakovi than to P. klawei in having (1) peduncular article 3 of antenna 1 lengest; (2) coxal plates 2-4 deep; and (sensu Bousfield 1984) distributed in the litter layer of New Zealand, Agilestia Friend, 1982 occurring in the forests of Australia (Friend 1982), Htiu)aiorchestia Bousfield, 1984 distributed in the Hawaiian Islands (Bousfield 1984), Tasmanorchestia Eriend, 1987 ftrom coastal areas of western Tasmania (Friend 1987), and Boushetdia Chou and Lee, 1996 occurring in the subtropical forests of Taiwan (Chou and Lee 1996). Common features among these genera and Lanorchestia include: (1) carpus of pereopod 4 slightly sherter than that of pereopod 3; (2) pereepods 5-7 heteropodeus; (3) coxal gills 2 and 6 larger than others; and (4) euter ramus of uropod 1 marginally bare.…”

We report on two allied genera of the Talitridae from Taiwan: Pacijiorchestia Bousfield, 1982 and Lanorchestia gen. nov. Taiwanese specimens representing Pacijbrchestia are not identified to species due to their poor condition, but examination of these specimens has led us to revise the generic diagnosis of Ilacijbrchestia. Specirnens of the two species assigned to Pacijbrchestia, P. klaLoei (Bousfield, 1961) (type species of the genus) and P. pyatahovi (Derzhavin, 1937), were also examined. Lanorchestia kanoi gen. et sp, nov. is described from Lanyu Island (==Lan-Hsu), a small istand ofTaiwan. Lanorchestia is compared with and differentiated frem the following allied genera:

“…The identity and number of individuals of each species of infauna in each flower were recorded and specimens were preserved in 70% ethanol. Isopods were identified using Hale (1929), the amphipods using Friend (1982) and by A. Richardson (pers. comm., 2005), and the collembolan infauna using Greenslade and Ireson (1986) and Greenslade (1994).…”

Aspidistras, amphipods and Oz: Niche opportunism between strangers in a strange land

The subterranean flowers of Aspidistra in their natural habitat of moist temperate East Asian forests are reportedly pollinated by terrestrial amphipods. Seed set by cultivated plants growing in Adelaide, South Australia, suggests that a pollinator shift has occurred and the results show that despite their different origins, the apparently highly specialized pollination system of the Asian Aspidistra can be accomplished by an introduced eastern Australian amphipod, Arcitalitrus sylvaticus . Pollination is possibly also achieved by cosmopolitan collembolans that feed on pollen inside the floral chambers. It appears that by providing subterranean floral chambers, Aspidistra potentially exploits the cryptic, fugitive behavior of soil or litter-dwelling invertebrates. This supports the theory of asymmetrical pollination where an apparently specialized flower is pollinated successfully through the generalized behavior of its pollinators.
