Survey #1 Stream benthic microorganisms in Ontario

Dewdney, A. K. 1996. Ecology in a Small Stream. Monograph, Environmental Science Program, UWO, London, Ontario, Canada.

This survey involved monthly sampling from the Logan Drain, a small stream in Middlesex Co. Presence/absence in a five-subsample series for each of two benthic samples provided a basis for numerical extimates of abundance during the May-October period of 1996. Included all Phyla/groups with stream benthic submillimeter representatives, from bacteria (morphospecies), protistan algae, ciliates, etc. to gastrotrichs, platyhelminthes, and insects (Chironomidae)

Hutto, R. L. 1995. Composition of bird communities following stand-replacement fires in northern Rocky Mountains (U.S.A.) conifer forests. Conservation Biology 9(5): 1041-1058.

This survey sampled birds in 33 burned forest sites in the Montana and Wyoming Rocky Mountains. Numbers are based on point counts taken along transects through the burned areas within one or two years of the burn. Total counts were reconstructed by multiplying point-averages (supplied in the only table) by the total number of survey points (597).

Stein, D. L., Tissot, B. N., Hixon, M. A., Barss, W. 1992. Fish-habitat associations on a deep reef at the edge of the Oregon continental shelf. Fishery Bulletin, U.S. 90: 540-551.

Schooling and non-schooling fish inhabiting a variety of bottom habitats on the Hecata Bank were sampled by submersible on 18 dives to 6 stations. Each dive followed transects with trained observers identifying and counting all fish seen. Fish were classified as “schooling” (in groups of
5 or more) or “non-schooling.” The data here represent counts only of the non-schooling fish, but one of these, the Pygmy Rockfish (Sebastes wilsoni) exceeded the logistic limit. The other species of Sebastes were all “schooling fish.” Might the excessive population of Neopomacentrus
azysron in Survey #21 be accounted for in the same way?

Survey #25 estuarine fish in Costa Rica

Winemiller, K. O., Leslie, M. A. 1992. Fish assemblages across a complex, tropical freshwater/marine ecotone. Environmental Biology of Fishes 34: 29-50.

A complex of streams and rivers feeds a marshy estuarine environment in Tortuguero Park on the coast of Costa Rica. Riverine fish were sampled by seive net from each of 16 sites that included low order streams, rivers, marsh, estuary and near coast’ habitat. “Intensive” sampling took
place during the summer of 1983, throughout 1985, and in the summer of 1986.

A study of the emergence of copepods from seagrass on nine dates from March 83 to August 84 used emergence traps. Table of average numbers per sp were used as data for this study. Some “species” were actually grouped (marked “spp”) and this distorted the abundance distribution
somewhat, neither distribution fitting particularly well.

Terborgh, John, Robinson, Scott K., Parker III, Theodore A., Munn, Charles A., Pierpont, Nina. 1990. Structure and organization of an Amazonian bird community. Ecological Monographs 60: 213-238.

A 3-month survey of a 97 ha plot in the Amazonian rain forest portion of Peru during the 1982 breeding season used a spot-mapping method. Breeding pairs were counted and abundances were reported as pairs/ha (density). The counts are somewhat suspect because cateÉgories that should have had a dozen species had none! for this reason, category width of 0.5 instead of 0.25 was used.

Helminths, a generic term for nematodes, cestodes, trematodes, etc. Authors surveyed helminth populations on two isolated populations of Mottled Duck along the Gulf Coast of North America. From both populations 20 ducks were shot and cleaned of helminths, which were subsequently ID’d and counted. Texas parasitic helminths were reported separately and used here, as they had more spp. than the Florida population.

Alaback, Paul B.and Herman, F. R. 1988. Long-term response of understory vegetation to stand density in Picea-Tsuga forests. Can. J. For. Res. 18:1522-1530.

The understorey vegetation in two sites, one dominated by Hemlock, the other by Spruce, was examined by the authors 17 years after selective cutting in a mountainous area of central coastal Oregon. The sampling was carried out within nine plots at each site, with four 4 m quadrats within each plot. The samples, which included woody and herbaceous plants, were recorded as the number of plots in which a species occurred. The Hemlock site was used here, with only the original plant species being counted, as these had more species.

During the 1993-94 season, the authors set up 15 one-hectare grids along an altitudinal gradient in the Negev Hgihlands of Israel. Each grid was subdivided into 25 plots, each 20 x 20m. Within each plot, three pitfall traps were placed at random. The traps were checked once a week for a month, individuals identified (then released), and counted. The abundance of each species is presented as the number of trapped individuals per functioning trap per week. The appendix of the paper appears to give the total number of individuals actually observed and these data were used here.

Survey #117 Fish in Louisiana

Rakocinski, C. F., Baltz, D. M., Fleeger, J. W. 1992. Corrrespondence between environmental gradients and the community structure of marsh-edge fishes in a Louisiana estuary. Mar. Ecol. Progr. Ser. 80:135-148.

The authors sampled fish in the Barataria Basin, a body of water that stretches 110 km from the Gulf of Mexico inland west of the Mississippi. Sampling was confined to the 145,000 ha Saltmarsh Zone. The authors used a drop-sampler in each of ten sites along two 25 km transects running along shorelines. During 1989, they took 287 drop samples, reporting on results of both spring and summer drop samples, counts from the former series used here.

Survey #118 Birds in New Hampshire

Holmes, Richard T., Sherry, Thomas W. 1986. Bird community dynamics in a temperate deciduous forest: long-term trends at Hubbard Brook. Ecological Monographs. 56(3):201-220.

Hubbard Brook Experimental Forest occupies 3076 ha in White Mountain National Forest. The authors sampled birds in a 10-ha forest plot used for other studies, previously. They used timed censuses involving paired observers 100 m apart moving at a fixed rate. Two censuses were conducted in each of seven weeks, starting in late May. They also used territory-mapping and mist-net captures. The study was conducted every summer, from 1969 to 1984. Data from 1971-72 were used here. Datat took the form of density (individuals/10 ha)

Survey #120 Grassland plants in Argentina

Pucheta, Eduardo, Cabido, Marcelo, Diaz, Sandra, Funes, Guillermo. 1998. Floristic composition, biomass, and aboveground net plant production in grazed and protected sites in a mountain grassland of central Argentina. Acta Oecologia 19(2):97-105.

In the 1993-94 growing season, the authors sampled three 25 x 25 m enclosed areas in grazing land on the Pampa de Achala of Argentina. The enclosures had been protected from grazing for 2, 4, and 15 years. Species frequencies within the enclosures were sampled in 10 randomly placed half-metre square plots. Mean frequencies for the three enclosures are reported by the authors and data for the 4 year protected enclosure were used in the metastudy.

Survey #121 Pasture plants in Australia

McIvor, John G. 1998. Pasture management in semi-arid tropical woodlands: effects on species diversity. Aus. J. Ecol. 23:349-364.

The effects of cattle ranching on plant diversity was studies by the author at two experimental sites in northeast Queensland annually from 1982 to 1992. At each site, nine plots were sampled for all plant species in 50 randomply placed 0.25 x 0.25 m quadrats. The frequencies were reported as densities per plot, the data from the Cardigan site being used here.

Survey #125 Land snails in Sweden

Wareborn, Ingvar. 1992. Changes in the land mollusc fauna and soil chemistry in an inland district in southern Sweden. Ecography 15: 62-69.

In order to detect impacts of soil acidification on fauna, the author sampled land snails in 55 localities near Vaxjo, Sweden in 1964-66 and again in 1987-88. He selected the sites with five distinct habitats and took all samples in each study within the same week. Each sample of 3 to 4 litres of litter and topsoil was seived and sorted trhough for slugs and snails. Data used here are for combined sites from the earlier study.
