We examined the habitat of juvenile haddock on the eastern Scotian Shelf (off Nova Scotia, Canada) in relation to grab-sampled benthic macrofaunal invertebrate species assemblages in order to determine whether there were significant differences in benthic macrofauna between areas of historically persistent high and low juvenile haddock abundance. Our analyses were conducted over two spatial sca...

diversity trends were similar among protists (foraminiferans and gromiids), metazoan macrofauna and megafauna along a transect (140–1850m water depth) across the OMZ during the 2003 intermonsoon (March–May) and late/post-monsoon (August–October) seasons. All groups exhibited some drop in abundance in the OMZ core (250–500m water depth; O2: 0.10–0.13mL L 1 1⁄4 4.46–5.80mM) but to differing degre...

Generalising or scaling up from small-scale experiments to larger areas is an important challenge for both ecology and conservation biology. This study describes a technique that attempts to meet this challenge by combining spatial mapping with small-scale process experiments. Specifically, we evaluate the density effects of large individuals ( . 15 mm shell length) of 2 a tellinid bivalve (Mac...

Soil compaction by farm machinery may persist for decades, hampering soil productivity and functioning. Assessing costs guiding recovery strategies are hindered paucity of data on structure rates. A long-term Structure Observatory was established a loamy in Switzerland to monitor after prescribed compaction, better assess the roles natural processes (vegetation, macrofauna, shrink-swell cycles)...
