Summary
Abstract – Habitat characteristics associated with lamprey ammocoetes (Lampetra spp.) were investigated at three different spatial scales: regional (Northern Ireland), catchment (Ballinderry River) and microhabitat. At the regional scale, ammocoetes were more abundant in rivers with a pH ‡8.2, while within a catchment, abundance was negatively related to the number of potential lamprey barriers and distance upstream. At the microhabitat scale, at sites where ammocoetes were present, ammocoetes were more abundant where median phi ‡1.94 (very coarse sand), where sediment depth ‡11.5 cm, and where kurtosis was >1.71. This study provides information on habitat associations of lamprey in the UK which may be of use in their conservation, [...]
Summary
Abstract – Habitat characteristics associated with lamprey ammocoetes
(Lampetra spp.) were investigated at three different spatial scales: regional
(Northern Ireland), catchment (Ballinderry River) and microhabitat. At the
regional scale, ammocoetes were more abundant in rivers with a pH ‡8.2,
while within a catchment, abundance was negatively related to the number
of potential lamprey barriers and distance upstream. At the microhabitat
scale, at sites where ammocoetes were present, ammocoetes were more
abundant where median phi ‡1.94 (very coarse sand), where sediment
depth ‡11.5 cm, and where kurtosis was >1.71. This study provides
information on habitat associations of lamprey in the UK which may be of
use in their conservation, in particular it highlights the negative association
of migration barriers with lamprey abundance.
