“…This has also been noted in other studies [10,12,59]. Rare colonies of L. muscorum and M. alaskensis were located in non-harvested stands, but only where there were either small openings in the canopy or more open forest structure, indicating that some queens must disperse within this landscape element and possibly select such openings at an intermediate scale.…”

Given both the ubiquity and ecological roles described for ants in British Columbia, an understanding of the habitat elements critical to predicting their presence is desirable. We used logistic regression to model the presence and absence of ants in sub-boreal lodgepole pine (Pinus contorta var. latifolia Engelm. ex S. Watson) forests of west-central British Columbia (BC). Methodological emphasis was placed on the association between ants and coarse woody debris (CWD) because of a high degree of utilization of this resource for nesting. Five species of ants, Camponotus herculeanus (L.), Formica aserva Forel, F. neorufibarbis Emery, Leptothorax muscorum (Nylander), and Myrmica alaskensis Wheeler, comprised approximately 90% of all captures in samples of CWD within five seral ages (2-3, 8-10, 13-15, 23-25 years post-harvest, and non-harvested stands). Seral age, presence of other ant colonies of the same species, decay class of CWD, its surface area, and whether the wood was downed woody debris (DWD) or a stump, were significant variables affecting ant presence or absence. These results are explained in the context of ant species autecology as it relates to living in cool climates.

“…While the investigations of the river Peene wetlands show positive effects of restoration despite creating discrete communities, other studies showed more mixed results with regard to the success of rewetting in restoring macroinvertebrate assemblages (Verberk et al ., ; Beadle et al ., ; Görn & Fischer, ; Punttila et al ., ). For instance, many rare and characteristic water beetles (Dytiscidae) such as Nartus grapii (Gyllenhal, 1808) and Laccophilus ponticus Sharp, 1882 were still absent in rewetted sites after 30 years, although source populations were present in the same bog (Van Duinen et al ., ).…”

Peatlands have undergone dramatic changes through anthropogenic activities in the last centuries, causing a substantial loss of fen‐specific biodiversity. Therefore, restoration of already degraded stands is an important conservation issue. The effectiveness of fen restoration was evaluated through rewetting in the valley of the river Peene, NE Germany, by comparing three fen types: drained fens, rewetted fens, and near‐natural fens. Rove beetles (Coleoptera: Staphylinidae) were used as indicators, comprising an ecologically important yet understudied insect group. 5,398 individuals from 121 staphylinid species were recorded by 30 pitfall traps per fen type, which were biweekly emptied between April and October 2012, and related to environmental parameters. Rove beetle assemblages differed markedly between fen types. Community structure was affected by peat degradation, the extent of organic matter, water level, and vegetation height. Fen rewetting favoured the establishment of a distinct, species‐rich beetle community within 15 years only, caused by an increase in hygrophilous wetland species partially replacing generalists. Nevertheless, this time span was not sufficient to restore communities characteristic for near‐natural fens, which harboured several particularly sensitive species that were not found on rewetted fens. Rewetting provided suitable habitats for a substantial number of stenotopic and threatened staphylinid beetles. Thus, the protection of pristine habitats along with restoration measures are both important strategies in peatland conservation.

1. Size polymorphism is often connected to alternative life-history traits, which may eventually lead to distinct size classes. In the ant Myrmica ruginodis, larger macrogyne and smaller microgyne queen morphs have been suggested to follow different reproductive strategies, which has presumably resulted in several differences in their key life-history traits.2. In this study, we examine the association of queen-size morphs with colony queen number (monogyny vs. polygyny), dispersal and queen recruitment patterns, as well as habitat associations of the queen morphs. We do this by sampling established queens from a large number of excavated nests from several populations, estimating genetic relatedness among coexisting queens and pitfall trapping free-ranging wingless queens.3. Our results show that associations of queen morphs with colony queen number and nest-founding strategy holds only partly. The morph frequencies vary widely across populations from practically pure macrogyne to more than 50% microgyne, but the expected association of macrogyne occurrence with monogyny and microgyne with polygyny is not universal. Dispersal and queen recruitment patterns also show that although most macrogynes participate in nuptial flights and most microgynes are recruited back to their natal nests, a fraction of both morphs use the alternative strategy.4. The polygynous microgyne morph has been suggested to specialize in stable habitats, but our results from Finnish mesic heath forests do not support this. This study shows that factors other than just queen size also influence life-history trait variation and reproductive strategies in ants.
