Existing livestock systems in Cumberland Co. rely mainly on grass, clover and spring cereals for home grown forage and grain. There are well known limitations to these systems on the fragipan or basil till soils which ...
The burrow microhabitat of the land crab Cardisoma guanhumi: Respiratory/ionic conditions and physiological responses of crabs to hypercapnia
Cardisoma guanhumi in Puerto Rico spend much of the dry season in burrows that descend to groundwater. Burrows are sometimes 3-4 m deep and may be capped with dried mud for over 3 mo. Samples of gas and water from burrows ...
Community structure and organization of tidepools
Although tidepools are conspicuous components of rocky intertidal shores, their biotic communities have not been studied as extensively as those on emergent substrata. We examine processes regulating the structure of ...
Free-Space Availability and Larval Substratum Selection as Determinants of Barnacle Population-Structure in a Developing Rocky Intertidal Community
Variation in settlement and recruitment of the barnacle Semibalanus balanoides (L.) was experimentally investigated in the high, mid and low intertidal zones at 2 adjacent sites (A and B) on a rocky shore in Nova Scotia, ...
Variations in Sampling Procedure and Frequency Affect Estimates of Recruitment of Barnacles
The influence of variations in sampling procedure and frequency on estimates of recruitment of the barnacle Semibalanus balanoides (L.) on an intertidal rocky shore at Sandy Cove, Nova Scotia, Canada was determined from ...
