Fig. 2 in Salinity Variation in a Mangrove Ecosystem: A Physiological Investigation to Assess Potential Consequences of Salinity Disturbances on Mangrove Crabs
Fig. 2. Dorsal view of Neosarmatium meinerti (A) and Tubuca urvillei (B). (C) Schematic representation of the experimental setup. For those analyses considering gill tissues (morphology, NKA activity and labelling), anterior and posterior gills were considered separately. The macroscopic view of N. meinerti and T. urvillei gill cavities are shown in D and E, respectively. The branchiostegite covering the branchial cavity has been removed. Gills are numbered from the anterior side of the crabs. Both species present a similar gill organization but different total gill number: whilst there are 2 podobranchs and 4 arthrobranchs for T. urvillei, N. meinerti possess 3 podobranchs and 4 arthrobranchs. (F) Histological section of a phyllobranchiate gill (T. urvillei) with flat leaf-like lamellae connected to a central axis distributing and collecting the circulating hemolymph. Anterior and posterior gills of both species present a similar branchial organisation. CA: central axis; cSW: concentrated seawater; dSW: diluted seawater; FW: freshwater; GL: gill lamellae; GT: gill tip; iSW: isosmotic seawater; N: dissecting needle; SW: seawater. Scale bars: A = 3 cm, B = 2 cm; C = 2 cm; D = 7 mm; E = 500 µm. *values adjusted to the isosmotic point of each of the two species according to the results provided in figure 3A.

Data from: Benefits and costs of ecological restoration: rapid assessment of changing ecosystem service values at a UK wetland
Restoration of degraded land is recognized by the international community as an important way of enhancing both biodiversity and ecosystem services, but more information is needed about its costs and benefits. In Cambridgeshire, U.K., a long-term initiative to convert drained, intensively farmed arable land to a wetland habitat mosaic is driven by a desire both to prevent biodiversity loss from the nationally important Wicken Fen National Nature Reserve (Wicken Fen NNR) and to increase the provision of ecosystem services. We evaluated the changes in ecosystem service delivery resulting from this land conversion, using a new Toolkit for Ecosystem Service Site-based Assessment (TESSA) to estimate biophysical and monetary values of ecosystem services provided by the restored wetland mosaic compared with the former arable land. Overall results suggest that restoration is associated with a net gain to society as a whole of $199 ha−1y−1, for a one-off investment in restoration of $2320 ha−1. Restoration has led to an estimated loss of arable production of $2040 ha−1y−1, but estimated gains of $671 ha−1y−1 in nature-based recreation, $120 ha−1y−1 from grazing, $48 ha−1y−1 from flood protection, and a reduction in greenhouse gas (GHG) emissions worth an estimated $72 ha−1y−1. Management costs have also declined by an estimated $1325 ha−1y−1. Despite uncertainties associated with all measured values and the conservative assumptions used, we conclude that there was a substantial gain to society as a whole from this land-use conversion. The beneficiaries also changed from local arable farmers under arable production to graziers, countryside users from towns and villages, and the global community, under restoration. We emphasize that the values reported here are not necessarily transferable to other sites.

Assessing the use of bison for savanna restoration at Cedar Creek Ecosystem Science Reserve: Aboveground Biomass
Oak savanna is the most threatened ecosystem in Minnesota and fire, alone, is not restoring and preserving it. Our savanna restoration research started more than a half century ago in what had once been native savanna at Cedar Creek. It has shown that burning about 4 to 7 times per decade eliminates shrubs and non-savanna tree species and restores prairie grassland species. However, our 50 years of research is also showing that these frequent and intense fires are preventing oaks from regenerating. Bison are now known to be a keystone species for restoring and preserving grasslands, but their roles in savanna ecosystems remain unknown. In grasslands, bison preferentially graze the dominant warm season grasses that would otherwise outcompete wildflowers, thereby promoting plant coexistence and enhancing plant diversity. Here we propose to test whether bison grazing might promote the growth and survivorship of oak seedlings in burned savannas by reducing grass fuel for fires and by knocking back dominant grass competitors. We will maintain the existing fire frequencies and the design of the long-term burning experiment, while adding bison grazing as an additional factor in part of several burn units on the southeast side of the property. Bison will graze during the summer and early fall seasons. Grazing exclosures will be established, and oak seedlings will be planted, to test effects of bison grazing on early oak growth and survivorship. The outcomes we plan to achieve are to: (1) discover better restoration and preservation practices for savanna ecosystems; (2) determine how these practices impact savanna biodiversity; and (3) educate Minnesotans about the ecological heritage of their state, including the roles that bison, fire and biodiversity play in the functioning of savannas and other Minnesota ecosystems. We will achieve these goals and outcomes by: (1) restoring bison grazing to 200 acres of oak savanna; (2) experimentally testing whether bison grazing promot
