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.

Systematics and Community Composition of Foraging
J. Sci. Univ. Kelaniya 7 (2012): 55-72 OCCURRENCE AND SPECIES DIVERSITY OF GROUND-DWELLING WORKER ANTS (FAMILY: FORMICIDAE) IN SELECTED LANDS IN THE DRY ZONE OF SRI LANKA R. K. SRIYANI DIAS AND K. R. K. ANURADHA KOSGAMAGE Department of Zoology, University of Kelaniya, Sri Lanka ABSTRACT Ants are an essential biotic component in terrestrial ecosystems in Sri Lanka. Worker ants were surveyed in six forests, uncultivated lands and, vegetable and fruit fields in two Districts of the dry zone, Anuradhapura and Polonnaruwa, from November, 2007 to October, 2008 by employing several sampling methods simultaneously along five, 100 m transects. Soil sifting, litter sifting, honey-baiting and hand collection were carried out at 5 m intervals along each transect. Twenty pitfall traps were set up throughout each site and collected after five hours. Air and soil temperatures, soil pH and soil moisture at each transect were also recorded. Use of several sampling methods yielded a higher value for species richness than just one or two methods; values for each land ranged from 19 – 43 species. Each land had its own ant community and members of Amblyoponinae, Cerapachyinae, Dorylinae, Leptanillinae and Pseudomyrmecinae were recorded for the first time from the dry zone. Previous records of 40 species belonging to 23 genera in 5 subfamilies for the Anuradhapura District are updated to 78 species belonging to 36 genera in 6 subfamilies. Seventy species belonging to thirty one genera in 9 subfamilies recorded from the first survey of ants in Polonnaruwa lands can be considered a preliminary inventory of the District; current findings updated the ant species recorded from the dry zone to 92 of 42 genera in 10 subfamilies. -
Diversity and Organization of the Ground Foraging Ant Faunas of Forest, Grassland and Tree Crops in Papua New Guinea
- - -- Aust. J. Zool., 1975, 23, 71-89 Diversity and Organization of the Ground Foraging Ant Faunas of Forest, Grassland and Tree Crops in Papua New Guinea P. M. Room Department of Agriculture, Stock and Fisheries, Papua New Guinea; present address: Cotton Research Unit, CSIRO, P.M.B. Myallvale Mail Run, Narrabri, N.S.W. 2390. Abstract Thirty samples of ants were taken in each of seven habitats: primary forest, rubber plantation, coffee plantation, oilpalm plantation, kunai grassland, eucalypt savannah and urban grassland. Sixty samples were taken in cocoa plantations. A total of 156 species was taken, and the frequency of occurrence of each in each habitat is given. Eight stenoecious species are suggested as habitat indicators. Habitats fell into a series according to the similarity of their ant faunas: forest, rubber and coffee, cocoa and oilpalm, kunai and savannah, urban. This series represents an artificial, discontinuous succession from a complex stable ecosystem to a simple unstable one. Availability of species suitably preadapted to occupy habitats did not appear to limit species richness. Habitat heterogeneity and stability as affected by human interference did seem to account for inter-habitat variability in species richness. Species diversity was compared between habitats using four indices: Fisher et al.; Margalef; Shannon; Brillouin. Correlation of diversity index with habitat hetero- geneity plus stability was good for the first two, moderate for Shannon, and poor for Brillouin. Greatest diversity was found in rubber, the penultimate in the series of habitats according to hetero- geneity plus stability ('maturity'). Equitability exceeded the presumed maximum in rubber, and was close to the maximum in all habitats. -
List of Indian Ants (Hymenoptera: Formicidae) Himender Bharti
List of Indian Ants (Hymenoptera: Formicidae) Himender Bharti Department of Zoology, Punjabi University, Patiala, India - 147002. (email: [email protected]/[email protected]) (www.antdiversityindia.com) Abstract Ants of India are enlisted herewith. This has been carried due to major changes in terms of synonymies, addition of new taxa, recent shufflings etc. Currently, Indian ants are represented by 652 valid species/subspecies falling under 87 genera grouped into 12 subfamilies. Keywords: Ants, India, Hymenoptera, Formicidae. Introduction The following 652 valid species/subspecies of myrmecology. This species list is based upon the ants are known to occur in India. Since Bingham’s effort of many ant collectors as well as Fauna of 1903, ant taxonomy has undergone major myrmecologists who have published on the taxonomy changes in terms of synonymies, discovery of new of Indian ants and from inputs provided by taxa, shuffling of taxa etc. This has lead to chaotic myrmecologists from other parts of world. However, state of affairs in Indian scenario, many lists appeared the other running/dynamic list continues to appear on web without looking into voluminous literature on http://www.antweb.org/india.jsp, which is which has surfaced in last many years and currently periodically updated and contains information about the pace at which new publications are appearing in new/unconfirmed taxa, still to be published or verified.

The Army Ant Aenictus Hottai (Hymenoptera: Formicidae: Aenictinae) and Related Species in Southeast Asia, with a Description Of
557 The Army AntAenictus hottai (Hymenoptera: Formicidae: Aenictinae) and Related Species in Southeast Asia, with a Description of a New Species by Decha Wiwatwitaya1 & Weeyawat Jaitrong2, 3 ABSTRACT The Aenictus hottai group is established to include two species (a named and a new species) occurring in Southeast Asia: Aenictus hottai Terayama et Yamane, 1989 and Aenictus yamanei Wiwatwitaya et Jaitrong, sp. nov. Both are probably restricted to Sundaland and inhabit lowland primary forests. Key words: Taxonomy, Formicidae, Aenictinae, Aenictus yamanei, army ants, new species. INTRODUCTION Currently 95 species are listed in the army ant genus Aenictus from the Oriental, Indo-Australian, and Australasian regions (Jaitrong & Eguchi 2010; Bolton 2011). Among them 67 species are known only from the worker caste. All of those species except one have a smooth and shining gaster. The species with a finely reticulated gaster, Aenictus hottai Terayama et Yamane, 1989, is also characterized by a well-developed subpetiolar process with a poster- oventrally produced arm, and is found only in Southeast Asia (Terayama & Yamane 1989; Rościszewski & Mashchwitz 1994; Malsch et al. 2003; Jaitrong & Nabhitabhata 2005). In the course of our examination of Aenictus specimens collected from Southeast Asia, we found another species from Malay Peninsula and Sarawak that is closely related to A. hottai but is much smaller than the latter. In this paper we describe this ant as a new species based on the worker caste and both species are classified into the Aenictus hottai group herein established. 1 Department of Forest Biology, Faculty of Forestry, Kasetsart University, Bangkok 10900, Thailand, E-mail: [email protected] 2 Thailand Natural History Museum, National Science Museum, Technopolis, Khlong 5, Khlong Luang, Pathum Thani 12120, Thailand, E-mail: [email protected] 3 Graduate School of Science and Engineering, Kagoshima University, Kagoshima 8900065, Japan 558 Sociobiology Vol. -
Three New Species of the Army Ant Genus Aenictus SHUCKARD, 1840 (Hymenoptera: Formicidae: Aenictinae) from Borneo and the Philippines
Z.Arb.Gem.Öst.Ent. 62 115-125 Wien, 19. 11. 2010 ISSN 0375-5223 Three new species of the army ant genus Aenictus SHUCKARD, 1840 (Hymenoptera: Formicidae: Aenictinae) from Borneo and the Philippines Herbert ZETTEL & Daniela Magdalena SORGER Abstract Descriptions of three new species of army ants are provided: Aenictus pfeifferi sp.n. from Sarawak, Borneo; Aenictus pangantihoni sp.n. from Camiguin, the Philippines; and Aenictus carolianus sp.n. from Cebu, the Philippines. Key words: Hymenoptera, Formicidae, Aenictus, army ants, new species, taxonomy, Philippines, Malaysia, Borneo, Cebu, Camiguin. Zusammenfassung Diese Arbeit liefert die Beschreibungen von drei Ameisenarten aus der Unterfamilie der Aenictinae (Treiberameisen): Aenictus pfeifferi sp.n. wird aus Sarawak, Borneo, beschrie- ben, Aenictus pangantihoni sp.n. von der Insel Camiguin, Philippinen, und Aenictus caro- lianus sp.n. von der Insel Cebu, Philippinen. Introduction The islands in the western Pacific region still yield a wealth of undescribed ant species. Despite the interesting biology of army ants – a review was published by KRONAUER (2009) – their taxonomy and zoogeography are poorly studied and need much more atten- tion. To our knowledge, the “true” army ants of the genus Aenictus SHUCKARD, 1840 (sub- family Aenictinae) are remarkably specious in the region. The described species are often recorded from a single island; this might be either an effect of reduced dispersal abilities or just a lack of information. Since WILSON’s (1964) taxonomic revision only a few species have been described from Southeast Asia, including one from Borneo (YAMANE & HASHIMOTO 1999), but none from the Philippines. In our present study we describe three species. -
THE TRUE ARMY ANTS of the INDO-AUSTRALIAN AREA (Hymenoptera: Formicidae: Dorylinae)
Pacific Insects 6 (3) : 427483 November 10, 1964 THE TRUE ARMY ANTS OF THE INDO-AUSTRALIAN AREA (Hymenoptera: Formicidae: Dorylinae) By Edward O. Wilson BIOLOGICAL LABORATORIES, HARVARD UNIVERSITY, CAMBRIDGE, MASS., U. S. A. Abstract: All of the known Indo-Australian species of Dorylinae, 4 in Dorylus and 34 in Aenictus, are included in this revision. Eight of the Aenictus species are described as new: artipus, chapmani, doryloides, exilis, huonicus, nganduensis, philiporum and schneirlai. Phylo genetic and numerical analyses resulted in the discarding of two extant subgenera of Aenictus (Typhlatta and Paraenictus) and the loose clustering of the species into 5 informal " groups" within the unified genus Aenictus. A consistency test for phylogenetic characters is discussed. The African and Indo-Australian doryline species are compared, and available information in the biology of the Indo-Australian species is summarized. The " true " army ants are defined here as equivalent to the subfamily Dorylinae. Not included are species of Ponerinae which have developed legionary behavior independently (see Wilson, E. O., 1958, Evolution 12: 24-31) or the subfamily Leptanillinae, which is very distinct and may be independent in origin. The Dorylinae are not as well developed in the Indo-Australian area as in Africa and the New World tropics. Dorylus itself, which includes the famous driver ants, is centered in Africa and sends only four species into tropical Asia. Of these, the most widespread reaches only to Java and the Celebes. Aenictus, on the other hand, is at least as strongly developed in tropical Asia and New Guinea as it is in Africa, with 34 species being known from the former regions and only about 15 from Africa. -

Introduction and Background on Proposed Action This biological assessment (BA) has been prepared by the United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS) to evaluate the potential effects on federally-listed threatened and endangered species and designated critical habitat from the movement of baled garbage and regulated (domestic) garbage (GRG) from the State of Hawaii for disposal at landfills in Oregon, Idaho, and Washington. Specifically, garbage is defined as urban (commercial and residential) solid waste from municipalities in Hawaii, excluding incinerator ash and collections of agricultural waste and yard waste. Regulated (domestic) garbage refers to articles generated in Hawaii that are restricted from movement to the continental United States under various quarantine regulations established to prevent the spread of plant pests (including insects, disease, and weeds) into areas where the pests are not prevalent. -
Hymenoptera: Formicidae) Inferred from Morphological and Genetic Evidence
Zoological Studies 58: 11 (2019) doi:10.6620/ZS.2019.58-11 Open Access Cryptic Diversity in the Widespread Asian Ant Crematogaster rothneyi (Hymenoptera: Formicidae) Inferred from Morphological and Genetic Evidence Shingo Hosoishi1,* and Kazuo Ogata1 1Institute of Tropical Agriculture, Kyushu University, 744 Motooka, Nishi-ku, Fukuoka 819-0395 Japan. *Correspondence: E-mail: [email protected] (Hosoishi) Received 28 January 2019 / Accepted 7 May 2019 / Published 24 June 2019 Communicated by John Wang The myrmicine species Crematogaster rothneyi is one of the most widely distributed ants in Asia, but it has rarely been collected in the field. Its distribution range covers South and SoutheastAsia, extending approximately 5,000 km from India in the west to Sulawesi in the east. Despite this wide distribution range, C. rothneyi has been treated as a single taxonomic species, and no combined morphological or molecular analysis has been conducted to assess whether any intraspecific variation exists. The sequence divergences of C. rothneyi populations, mainly obtained from Southeast Asia, were investigated by analyzing 387 bp and 175 bp sequences of the 12S ribosomal RNA and cytochrome c oxidase subunit (COI) genes, respectively. Phylogenetic analysis indicated that the C. rothneyi populations were separated into three groups: group I from Thailand and Cambodia, group II from Bangladesh and Myanmar, and group III from Krakatau and Sulawesi. Groups II and III were recovered as a single clade, sister to group I. The interspecific divergences were 7.3% to 8.5% for 12S and 14.5% to 23.3% for COI between most C. rothneyi specimens and Cambodian specimens, while divergence for 12S was 3.5% between Thai and Cambodian specimens. -

Vos1;∗ 1 Endless Forms, Naturalis Biodiversity Center, Leiden, 2333 BA, Netherlands *[email protected] Abstract 1 The well-documented, species-rich, and diverse group of ants (Formicidae) are important 2 ecological bioindicators for species richness, ecosystem health, and biodiversity, but ant 3 species identification is complex and requires specific knowledge. In the past few years, 4 insect identification from images has seen increasing interest and success, with processing 5 speed improving and costs lowering. Here we propose deep learning (in the form of a 6 convolutional neural network (CNN)) to classify ants at species level using AntWeb 7 images. We used an Inception-ResNet-V2-based CNN to classify ant images, and three 8 shot types with 10,204 images for 97 species, in addition to a multi-view approach, for 9 training and testing the CNN while also testing a worker-only set and an AntWeb 10 protocol-deviant test set. Top 1 accuracy reached 62% - 81%, top 3 accuracy 80% - 92%, 11 and genus accuracy 79% - 95% on species classification for different shot type approaches. 12 The head shot type outperformed other shot type approaches.
