Soil nitrate and ammonium: Total C and N Storage Along Wetland-Upland Gradients
An examination of total C and N storage along upland-wetland gradients was initiated during August 1991. Three transects in sedge and graminoid dominated wetlands were established, with plots beginning in an upland prairie vegetation zone and ending in the center of the wetland. Within each vegetation zone and at each of the transitions between these zones, a core of soil or peat was collected. Cores were approximately 60-90cm in length, and in most cases, penetrated the mineral soil. The core was cut into 5-10cm sections or was cut at distinct changes in soil color or texture. The samples were tested for total C and N with a Carlo Erba analyzer. An additional set of cores, 20cm in length, were collected for separation and analysis of root biomass. In a 1 m2 plot at each of the core sites, the vegetation was described by estimating percent cover of each species. Above ground biomass was then collected along the transect in the middle of vegetation zones (but not at the transitions). Three randomly selected 1 m2 plots per zone were cleared of standing biomass and litter. The vegetation was dried and weighed, and a subsample from each plots litter was collected for analysis. Total C and N were measured on the Carlo Erba analyzer. Additional transects will be established during the summer of 1992 to include a wider range of wetland types.
Data from: Habitat usage of Daubenton's bat (Myotis daubentonii), common pipistrelle (Pipistrellus pipistrellus), and soprano pipistrelle (Pipistrellus pygmaeus) in a North Wales upland river catchment
Distributions of Daubenton's bat (Myotis daubentonii), common pipistrelle, (Pipistrellus pipistrellus), and soprano pipistrelle (Pipistrellus pygmaeus) were investigated along and altitudinal gradient of the Lledr River, Conwy, North Wales, and presence assessed in relation to the water surface condition, presence/absence of bank‐side trees, and elevation. Ultrasound recordings of bats made on timed transects in summer 1999 were used to quantify habitat usage. All species significantly preferred smooth water sections of the river with trees on either one or both banks; P. pygmaeus also preferred smooth water with no trees. Bats avoided rough and cluttered water areas, as rapids may generate high‐frequency echolocation‐interfering noise and cluttered areas present obstacles to flight. In lower river regions, detections of bats reflected the proportion of suitable habitat available. At higher elevations, sufficient habitat was available; however, bats were likely restricted due to other factors such as a less predictable food source. This study emphasizes the importance of riparian habitat, bank‐side trees, and smooth water as foraging habitat for bats in marginal upland areas until a certain elevation, beyond which bats in these areas likely cease to forage. These small‐scale altitudinal differences in habitat selection should be factored in when designing future bat distribution studies and taken into consideration by conservation planners when reviewing habitat requirements of these species in Welsh river valleys, and elsewhere within the United Kingdom.
