“…The incisor process of C. macroura also bears similarity to that of B. raptor and the rapacious decapod Procaris ascensionis Chace and Manning, 1972, in being relatively pronounced, sharp, and blade-like (Chace and Manning, 1972;Rogers et al, 2006). The morphology and remarkable size of the mandible of C. macroura suggests that it may have been a predatory species.…”

Phyllocarids of the Waukesha Biota were systematically and taphonomically evaluated. Three Ceratiocaris species are present in the biota: C. macroura Collette and Rudkin, 2010; C. papilio Salter in Murchison, 1859; and C. pusilla Matthew, 1889. Specimens range in completeness from nearly complete, including the cephalic to caudal regions, to isolated telsons and furcae. Evidence of Salter's position is present in only three specimens. Relatively complete specimens are interpreted to represent corpses, rather than molts; whereas specimens including only the pleon and caudal region, or caudal region, and specimens with evidence of Salter's position likely represent exuviae. Specimens are preserved essentially as compression fossils exhibiting two types of preserved cuticle: brown inner cuticle, which tends to be impressed over the topography of bedding planes on which specimens are preserved, and blue-gray phosphatized cuticle exhibiting sub-millimeter scale relief. Cuticle phosphatization likely occurred during early diagenesis. The presence of characteristic near-shore species and C. pusilla, only known from turbidite facies, interpreted to possibly represent a marine trough, suggests that the Waukesha phyllocarid assemblage might represent a transported assemblage, rather than a biota, or that C. pusilla from the Jones Creek Formation was transported basinward in sediment gravity flows.

“…Anostraca consume a wide variety of organic particles, such as phytoplankton and bacteria (Brendonck 1993a,b, Dierckens et al 1997 and are also known to ingest rotifers (Starkweather 2005), nematodes, cladocerans (Bernice 1971) and other small invertebrates (Mertens et al 1990). Some large anostracans even actively hunt and predate on other organisms (Fryer 1966, White et al 1969, Rogers et al 2006. The omnivory of Anostraca allows them to utilize a wide range of food types, providing the necessary fl exibility to survive in these nutrient poor habitats.…”

Abstract:The length of the hydrocycle restrains the development of communities in temporary aquatic habitats. Little information is available on the importance of biotic interactions in shaping the communities in these habitats. A common observation in the freshwater rock pool community assembly process is the clearly separated density peaks of fairy shrimp (Anostraca) and cladocerans (Anomopoda) over time. Fairy shrimp (Anostraca), the fl agship group and dominant fi lter feeders of temporary waters hatch early after inundation. This contrasts with the occurrence pattern of coexisting cladocerans, which despite higher chances of abortive hatching occur later during the hydroperiod. To study this apparent succession pattern and test the possible presence of a biotic interaction, we set up enclosure experiments in freshwater rock pools in Western Australia and monitored cladoceran (Macrothrix hardingii) densities in the presence of variable densities or absence of fairy shrimp (Branchinella longirostris). The anomopod cladoceran populations decreased with increasing anostracan densities revealing a negative biotic interaction. The competitive dominance of anostracans most probably was mainly due to exploitation competition, with possibly elements of interference competition or predation included. Early hatching and competitive superiority may help anostracans in temporary pools to monopolize the habitat with respect to small and/or other fi lter feeding invertebrates. As such they infl uence succession dynamics and invertebrate community structure, making anostracans keystone species of temporary pools.

“…These two species co-occur, and are potential competitors; however B. hiberna rapidly grows to maturity in about a third less time than B. disimilis. Branchinecta hiberna was also reported as cöoccurring with B. lindahli and B. coloradensis Packard, 1874 in Idaho (in separate habitats), with the same rapid development and maturing faster than the other two species (Rogers et al, 2006). Two of the B. mackini Dexter, 1956 populations listed in Tab.…”

“…However, when subjected to conditions from its origin, hatching did occur, but at a lower fraction than for the same cultures that were only given origin conditions. This suggests that the Riverside County conditions either caused some mortality or provided hatching inhibition cues (Belk, 1973;Belk and Nelson, 1995 Different lineages sharing a single habitat have been observed in the genus Branchinecta; however these lineages were different species (Eriksen and Belk, 1999;Rogers and Fugate, 2001;Rogers et al, 2006).
