Local adaptation to climate change in a calcareous grassland system
… and rainfall have been maintained in intact calcareous grassland since 1993 at the Buxton Climate Change Impacts Laboratory (BCCIL) in northern England (UK). Here I investigated the role of local adaptation as mechanism of the apparent resistance of species' to long-term climate manipulations …

Cellular and molecular characterisation of regeneration in calcareous sponges and soft corals
… of soft corals from the genus Xenia and calcareous sponges from the genus Sycon. Cnidarians, which include corals, sea anemone, and jellyfish, are renowned for their remarkable regenerative abilities. Occupying a key phylogenetic position as the sister group to Bilateria, cnidarians offer …

SUBSURFACE DRIP IRRIGATION AND UREA PHOSPHATE USE IN VEGETABLES ON CALCAREOUS SOILS.
… surface and furrow irrigation were compared on calcareous soils of southern Arizona. Crops grown were zucchini squash (Cucurbita pepo L.) 1982 and 1983 summers, and cabbage (Brassica oleracea var. capitata L.), 1982 fall. Furrows received a preplant application of phosphorus (P) at a rate of 100 …

Microbial and Chemical Affects on Leachate from Calcareous Soils Treated with Wastewater Effluent
… waters to natural and artificially constructed calcareous soils in greenhouse and field lysimeters, and in soil columns. The leachate from one field lysimeter contained increased fecal coliform counts than the effluent. Leachate coliform counts were decreased or not significantly changed in two …

Liquefaction Susceptibility of Uncemented Calcareous Sands From Puerto Rico by Cyclic Triaxial Testing
… the liquefaction susceptibility of uncemented calcareous sands. A series of isotropically consolidated undrained monotonic and cyclic triaxial tests were performed using the Playa Santa sand from Porto Rico. Playa Santa sand is a poorly graded calcareous clean beach sand composed of angular …

Ecology and paleoecology of marine invertebrate communities in calcareous substrates, Northeast Quintana Roo, Mexico
A survey of benthic communities in the vicinity of Isla Cancun and Isla Contoy, Territory of Quintana Roo, Mexico, demonstrates that invertebrate death assemblages (i.e., future fossil assemblages) in this region reflect the in-place accumulation of remains of living benthic communities through …

Long-Term Hydrologic Sustainability of Calcareous Fens Along Glacial Lake Agassiz Beach Ridges, Northwestern Mn
Calcareous fens are peat-accumulating wetlands fed by calcium-rich groundwater that support several threatened species of plants that evolved to thrive in these geochemical conditions. Fifty-three of Minnesota’s nearly 300 identified calcareous fens are located in the Glacial Lake Agassiz beach …

Late cretaceous (Maestrichtian) calcareous nannoplankton biogeography with emphasis on events immediately preceding the cretaceous/paleocene boundary
The Maestrichtian biogeography of calcareous nannoplankton is investigated in order to characterize paleoenvironmental conditions in the marine photic zone during the latest Cretaceous. Different theories explaining the biospheric turnover at the Cretaceous/Paleocene (KIP) boundary have …

An investigation of the influence of drought and other soil factors on the structure of a calcareous grassland.

Improved petrophysical evaluation of consolidated calcareous turbidite sequences with multi-component induction, NMR, resistivity images, and core measurements
We introduce a new quantitative approach to improve the petrophysical evaluation of thinly bedded sand-shale sequences that have undergone extensive diagenesis. Formations under analysis consist of carbonate-rich clastic sediments, with pore system heavily reworked by calcite and authigenic clay …
