use refuge areas for shelter during adverse periods of the year (Bedford & Usher, 1994).
assemblages with pitfall traps: the madness and the method.
Consequently, our results show Carabids
and rove beetles to be the most abundant beetles also in semi-coke heaps, their number per trap depends on climatic conditions during the sampling period.
Foraging activity of the carabid
beetle Pterostichus melanarius III in field margin habitats.
are taxonomically well known, with relatively stable systamatics and their ecology has been widely studied due to their sensitivity to environment, and productive role in agriculture (Lovei and Sunderland, 1996).
The most commonly identified species was Harpalus pensylvanicus, a carabid
beetle that was found in the feces of 11 bats (27.
Other species present on the island that are in a poor conservation status, include the carabids
(Asaphidion delatorrei, Dicrodontus alluaudi, Pseudomyas dorasensis and Paradromius tamaranus).
On the other hand, it is interesting to note that carabids
were collected in greater quantities in the pasture, contrary to the principle that the population of these insects is often negatively affected by grazing management practices (Rainio and Niemela, 2003.
The effect of pesticides on the community of carabids
in spring rape fields.
Vascular plants as a surrogate species group in complementary site selection for bryophytes, macrolichens, spiders, carabids
, staphylinids, snails, and wood living polypore fungi in a northern forest.
Niemela JK, Spence JR (1994) Distribution of forest dwelling carabids
(Coleoptera): spatial scale and the concept of communities.
Predatory activity and spatial pattern: the response of generalist carabids
to their aphid prey.
Other species of herbivores that spend a large proportion of their life cycles in cryptic locations are not susceptible to significant predation by carabids
, staphylinids, and spiders but are susceptible to specialist natural enemies (Ramert & Ekbom 1996).
The genera of the carabids
found are of neotropical origin.
Essentially serving as woodland refugia, these sites are dominated numerically by tenebrionids, although the stabilized soils and accumulated humus and leaf litter contribute to habitats capable of supporting a great taxonomic array of carabids
and scarabaeoids at all life stages.
