“…This study demonstrates that restoration efforts in the Everglades, Lake Okeechobee, Kissimmee River, and the upper basin of the St. Johns River would benefit from the incorporation of spatial aspects of the ecology of trophically important taxa such as the crayfish P. alleni. Specifically, we suggest that monitoring efforts be stratified with respect to dominant habitat types (Jordan et al 1994, Streever et al 1995, especially those plant taxa that are being targeted for reduction or enhancement (e.g., cattail, sawgrass, Hydritla ).…”

Spatial ecology of the crayfishProcambarus alleni in a Florida wetland mosaic

We investigated patterns of differential habitat occupation by the crayfish Procambarus alleni, a numerically abundant and trophically important species in freshwater marsh systems of southern Florida. Crayfish were collected from emergent wet prairies and sloughs in marshes forming the headwaters of the St. Johns River, Florida between August 1992 and December 1993. In addition to differences in plant species composition, wet prairies had greater plant biomass and lower water depths than sloughs. Mean density and biomass of crayfish were significantly higher in the densely vegetated wet prairies (28 per m2; 26.9 g per m 2) than in aquatic sloughs (3 per m2; 1.5 g per m2). Crayfish density increased with increasing plant biomass (i.e., habitat complexity) in wet prairies, whereas crayfish density decreased with increasing water levels (i.e., hydroperiod) within slough habitats. Recruitment occurred throughout the study, and the majority of crayfish collected were small in size (< 1.0 g). Ovigerous females were rarely collected and were found only in wet prairies. Differences it+ relative risk of predation, food availability, or a combination of lhese factors are likely generating differences in habitat occupation by the crayfish P. alteni in this wetland habitat mosaic. Efforts to restore and manage freshwater marshes in southern Florida (e.g., Everglades, Lake Okeechobee, Kissimmee River, St. Johns River) would benefit by considering spatial aspects of the ecology of indicator taxa such as crayfish.

“…It was not surprising that invertebrate abundance, diversity, and production was so much higher in emergent areas. Numerous studies have observed a direct relation between invertebrate production and aquatic vegetation (Wilcox, 1992;Streever et al, 1995;Zimmer et al, 2000). Specifically, Streever et al (1995) sampled invertebrate populations between vegetated and non-vegetated areas in a constructed wetland in Florida and found higher abundances in emergent areas.…”

“…Many studies that do exist preclude a comprehensive evaluation of all invertebrate taxa, and instead, focus on specific taxa deemed important to wetland health (Streever & Crisman, 1993;Streever et al, 1995Streever et al, , 1996Ashley et al, 2000;Fairchild et al, 2000;Johnson et al, 2000). Data are needed on the invertebrate assemblages of mitigated wetland habitats to ensure that communities are developing similarly to naturally functioning wetlands.…”

Aquatic macroinvertebrate assemblages in mitigated and natural wetlands

Many wetlands have been constructed in West Virginia as mitigation for a variety of human disturbances, but no comprehensive evaluation on their success has been conducted. Macroinvertebrates are extremely valuable components of functioning wetland ecosystems. As such, benthic and water column invertebrate communities were chosen as surrogates for wetland function in the evaluation of 11 mitigation and 4 reference wetlands in West Virginia. Mitigation wetlands ranged in age from 4 to 21 years old. Overall familial richness, diversity, density and biomass were similar between mitigation and reference wetlands (p > 0.05). Within open water habitats, total benthic invertebrate density was higher in reference wetlands, but mass of common taxa from water column samples was higher in mitigation wetlands (p < 0.05). Planorbidae density from benthic samples in emergent habitats was higher in reference than mitigated wetlands. Benthic Oligochaeta density was higher across open water habitats in mitigation wetlands. All other benthic taxa were similar between wetland types. Among the most common water column orders, Isopoda density was higher in reference wetlands, but Physidae density was higher in mitigation wetlands. Within mitigation wetlands, emergent areas contained higher richness and diversity than open areas. These data indicate that mitigation and reference wetlands generally support similar invertebrate assemblages, especially among benthic populations. The few observed differences are likely attributable to differences in vegetative community composition and structure. Mitigation wetlands currently support abundant and productive invertebrate communities, and as such, provide quality habitat for wetland dependent wildlife species, especially waterbirds and anurans.

“…Thus, we suggest that across a larger spatial and time scale, aquatic plantings have a positive effect on aquatic beetle assemblages. Other authors also emphasize the positive correlations between aquatic vegetation and macroinvertebrate diversity (Stewart and Downing 2008) and abundance (e.g., Streever et al 1995, Kurashov et al 1996, Hornung and Foote 2006, Strayer and Malcolm 2007, indicating that vegetation planting is a useful wetland restoration management technique. Besides providing food and cover, aquatic vegetation increases physical heterogeneity and creates additional living spaces for macroinvertebrates (Gregg and Rose 1985).…”

We tested wetland-restoration management techniques to restore and increase the diversity of aquatic beetle assemblages. Three wetland treatments were examined that included: (i) unplanted surface flow (unplanted SF) wetland, (ii) surface flow (planted SF) wetlands planted with aquatic plants, and (iii) subsurface flow (SSF) wetlands. Species richness of aquatic beetles in SF wetlands was highest in spring, while the abundance was lower in the planted SF wetlands than in the unplanted SF wetland. Planted SF wetlands had a slightly higher diversity of beetles than that of the unplanted SF wetland. The planted and unplanted SF wetlands had similar attributes throughout the rest of the year. In SSF wetlands, beetles were significantly more abundant and species rich in spring than either in the planted or in the unplanted SF wetlands. Beetle diversity in SSF wetlands was higher than that in SF wetlands. During the summer, the differences between treatments disappeared. Our results suggested that: (i) vegetation planting was a successful wetland restoration technique, due to the increased habitat diversity, (ii) subsurface flooding provided fishless temporary waters with favorable breeding conditions for aquatic beetles, thus it was also a useful restoration technique, and (iii) significant seasonal differences in abundance and species richness reflected the characteristic breeding habits of aquatic beetles.
