Article Reference Ant assemblage structure on cocoa trees in smallholder farms in the Centre Region of Cameroon
We investigated the ant community structure in cocoa farms in the Centre Region of Cameroon. Ants were collected on the cocoa trees during the years 2006 and 2007 using chemical knock‐down. We tested the hypothesis of the existence of deterministic factor in the structuration of ant mosaic using C‐Score; we assessed the relationship between the numerical dominant and subdominant ant species using Spearman correlation test and discussed on the influence of vegetation structure and farm management on the ant community structure. A total of 53 ant species belonging to 20 genera and five subfamilies were identified from a set of 51,525 workers collected. C‐score analysis supported the hypothesis that ant community were structured by competition. Negative relationships were found between dominant ant species. Farming practices which were mainly pruning, chemical treatment and habitat structure appeared to influence the ecological status and distribution of dominant ant species.

Article Reference Octet Stream Ant biodiversity conservation in Belgian calcareous grasslands: Active management is vital
A list of ant species collected in eight calcareous grasslands in the Viroin valley (Viroinval, Belgium) is presented. Thirty species were identified, including Temnothorax albipennis, for the first time recorded in Belgium. Ant community composition and chorology of some ant species are discussed. Recommendations on how to use ant community composition and nest densities of several ant species to evaluate management in calcareous grasslands are given. It appears that in locations with encroachment of tall grasses (especially Brachypodium pinnatum) and spontaneous afforestation, due to a complete lack of or to inadequate management, most of the often rare xerophilic ant species are replaced by mesophilic, rather common species.

Article Reference Ant communities in recently restored dune grassland ecosystems in Belgium (Hymenoptera: Formicidae)
In the period 2000-2001 nature restoration projects drastically reshaped the Nature Reserve in Lombardsijde near the Ijzer Estuary in Flanders, Belgium. Dikes were constructed and new dune grasslands were installed. Seven years after the restoration the ant fauna of these newly created sites was compared with reference sites from foredunes, dune grasslands and grey dunes. Ants were collected with pitfall traps in 10 sample sites during 4 years. Our results showed that after 7 even 10 years of nature restoration, the ant fauna in the newly created sites still differs substantially from those of the reference sites. However, typical dune grassland ant species like Myrmica specioides, Myrmica sabuleti and Lasius psammophilus were already present at the newly created sites. Our data also suggests that it takes a longer period for characteristic dune grassland ants species to colonize and settle in these new environments than for other invertebrate groups like spiders and carabid beetles that were also collected and studied during the same project and reported before.

Article Reference Ant–plant relationships in the canopy of an Amazonian rainforest: the presence of an ant mosaic
Using different techniques to access the canopy of an Amazonian rainforest, we inspected 157 tree crowns for arboreal ants. Diversity statistics showed that our study sample was not representative of the tree and ant populations due to their high diversity in Amazonian rainforests, but permitted us to note that a representative part of territorially dominant arboreal ant species (TDAAs) was inventoried. Mapping of TDAA territories and use of a null model showed the presence of an ant mosaic in the upper canopy, but this was not the case in the sub-canopy. Among the TDAAs, carton-nesting Azteca dominated (52.98% of the trees) whereas ant-garden ants (Camponotus femoratus and Crematogaster levior), common in pioneer formations, were secondarily abundant (21.64% of the trees), and the remaining 25.37% of trees sheltered one of 11 other TDAAs. The distribution of the trees forming the upper canopy influences the structure of the ant mosaic, which is related to the attractiveness of some tree taxa for certain arboreal ant species and represents a case of diffuse coevolution.
