Digging Deeper Into the Ecology of Subterranean Ants: Diversity and Niche Partitioning Across Two Continents
diversity Article Digging Deeper into the Ecology of Subterranean Ants: Diversity and Niche Partitioning across Two Continents Mickal Houadria * and Florian Menzel Institute of Organismic and Molecular Evolution, Johannes-Gutenberg-University Mainz, Hanns-Dieter-Hüsch-Weg 15, 55128 Mainz, Germany; [email protected] * Correspondence: [email protected] Abstract: Soil fauna is generally understudied compared to above-ground arthropods, and ants are no exception. Here, we compared a primary and a secondary forest each on two continents using four different sampling methods. Winkler sampling, pitfalls, and four types of above- and below-ground baits (dead, crushed insects; melezitose; living termites; living mealworms/grasshoppers) were applied on four plots (4 × 4 grid points) on each site. Although less diverse than Winkler samples and pitfalls, subterranean baits provided a remarkable ant community. Our baiting system provided a large dataset to systematically quantify strata and dietary specialisation in tropical rainforest ants. Compared to above-ground baits, 10–28% of the species at subterranean baits were overall more common (or unique to) below ground, indicating a fauna that was truly specialised to this stratum. Species turnover was particularly high in the primary forests, both concerning above-ground and subterranean baits and between grid points within a site. This suggests that secondary forests are more impoverished, especially concerning their subterranean fauna. Although subterranean ants rarely displayed speciﬁc preferences for a bait type, they were in general more specialised than above-ground ants; this was true for entire communities, but also for the same species if they foraged in both strata.

Origins and Affinities of the Ant Fauna of Madagascar
Biogéographie de Madagascar, 1996: 457-465 ORIGINS AND AFFINITIES OF THE ANT FAUNA OF MADAGASCAR Brian L. FISHER Department of Entomology University of California Davis, CA 95616, U.S.A. e-mail: [email protected] ABSTRACT.- Fifty-two ant genera have been recorded from the Malagasy region, of which 48 are estimated to be indigenous. Four of these genera are endemic to Madagascar and 1 to Mauritius. In Madagascar alone,41 out of 45 recorded genera are estimated to be indigenous. Currently, there are 318 names of described species-group taxa from Madagascar and 381 names for the Malagasy region. The ant fauna of Madagascar, however,is one of the least understoodof al1 biogeographic regions: 2/3of the ant species may be undescribed. Associated with Madagascar's long isolation from other land masses, the level of endemism is high at the species level, greaterthan 90%. The level of diversity of ant genera on the island is comparable to that of other biogeographic regions.On the basis of generic and species level comparisons,the Malagasy fauna shows greater affinities to Africathan to India and the Oriental region. Thestriking gaps in the taxonomic composition of the fauna of Madagascar are evaluatedin the context of island radiations.The lack of driver antsin Madagascar may have spurred the diversification of Cerapachyinae and may have permitted the persistenceof other relic taxa suchas the Amblyoponini.

BLAIMER Department of Entomology, University of California-Davis, One Shields Ave, Davis, CA 95616. E-mail: [email protected]; [email protected] Abstract Crematogaster ants are diverse, widespread and abundant in tropical, subtropical and warm-temperate climates throughout the world. The species diversity of this genus has been notoriously difficult to manage based upon morphology alone, and former attempts have generated a vaguely defined subgeneric system. I propose an improvement of the previous subgeneric classification and recognize two subgenera based upon a concurrent molecular study of the global diversity of these ants. Five of 13 former subgenera of Crematogaster are hereby synonymised under the subgenus Orthocrema Santschi: Neocrema Santschi syn. nov., Eucrema Santschi syn. nov., Rhachiocrema Mann syn. nov., Mesocrema Santschi syn. nov. and Apterocrema Wheeler syn. nov.. The eight remaining subgenera are synonymised under the subgenus Crematogaster sensu stricto: Decacrema Forel syn. nov., Oxygyne Forel syn. nov., Atopogyne Forel syn. nov., Sphaerocrema Santschi syn. nov., Colobocrema Wheeler syn. nov., Paracrema Santschi syn. nov., Physocrema Forel syn. nov. and Xiphocrema Forel syn. nov.. I present keys, morphological diagnoses and illustrations for the two revised, globally distributed subgenera Orthocrema and Crematogaster sensu stricto, based upon the worker caste. The two subgenera can be distinguished from each other by a combination of features of the petiole, postpetiole and propodeal spiracle.

Two New Primitive Ant Genera from the Late Eocene European Ambers
Two new primitive ant genera from the late Eocene European ambers GENNADY M. DLUSSKY and ALEXANDER G. RADCHENKO Dlussky, G.M. and Radchenko, A.G. 2009. Two new primitive ant genera from the late Eocene European ambers. Acta Palaeontologica Polonica 54 (3): 435–441. DOI: 10.4202/app.2008.0092. Two extinct genera of ants from the late Eocene (ca. 40 Ma), Protomyrmica gen. nov. and Plesiomyrmex gen. nov. (family Formicidae, subfamily Myrmicinae), are described based on single specimens (males), from Baltic and Bitterfeld (also called Saxonian) ambers respectively; both genera belong to the tribe Myrmicini. In gross morphology they are similar to modern Myrmica but have a series of apomorphies combined with characters that are plesiomorphic not only in the tribe Myrmicini, but also in the subfamily Myrmicinae. The most significant plesiomorphies concern the antennal structure and wing venation of both genera. The antennal scape is short and the funiculus is filiform, having no apical club. More− over, the antennae of Protomyrmica are “sphecoid” with the length of the funicular segments gradually decreasing to− wards the apex (i.e., the longest is basal, starting from the second, and the shortest is apical); this type of structure is basal for the family Formicidae as a whole. Although we consider the wing venation of Protomyrmica to represent the proto− type of wings in the subfamily Myrmicinae, it has an apomorphy absent in the modern Myrmicini genera—the antennae are inserted into the head well behind the posterior margin of the clypeus. Plesiomyrmex also has a peculiar apomorphy not found in any other genus of Myrmicinae: the antennae are inserted into toruli located on short sub−vertical tube−like or cup−like structures that protrude distinctly above the head surface.

ORIGINAL ARTICLE doi:10.1111/evo.13117 Defensive traits exhibit an evolutionary trade-off and drive diversification in ants Benjamin D. Blanchard1,2,3 and Corrie S. Moreau2 1Committee on Evolutionary Biology, University of Chicago, Chicago, Illinois 60637 2Department of Science and Education, Integrative Research Center, Field Museum of Natural History, Chicago, Illinois 60605 3E-mail: bblanchard@fieldmuseum.org Received July 9, 2016 Accepted November 1, 2016 Evolutionary biologists have long predicted that evolutionary trade-offs among traits should constrain morphological divergence and species diversification. However, this prediction has yet to be tested in a broad evolutionary context in many diverse clades, including ants. Here, we reconstruct an expanded ant phylogeny representing 82% of ant genera, compile a new family-wide trait database, and conduct various trait-based analyses to show that defensive traits in ants do exhibit an evolutionary trade- off. In particular, the use of a functional sting negatively correlates with a suite of other defensive traits including spines, large eye size, and large colony size. Furthermore, we find that several of the defensive traits that trade off with a sting are also positively correlated with each other and drive increased diversification, further suggesting that these traits form a defensive suite. Our results support the hypothesis that trade-offs in defensive traits significantly constrain trait evolution and influence species diversification in ants. KEY WORDS: Ancestral state reconstruction, defense, evolutionary trade-off, Formicidae, trait-based diversification. All species experience constraints arising from developmental, Trait trade-offs influence various evolutionary processes, in- functional, and energetic limitations. These limitations have fea- cluding patterns of morphological divergence (DeWitt et al.
