Global Models of Ant Diversity Suggest Regions Where New Discoveries Are Most Likely Are Under Disproportionate Deforestation Threat
Global models of ant diversity suggest regions where new discoveries are most likely are under disproportionate deforestation threat Benoit Guénard1, Michael D. Weiser, and Robert R. Dunn Department of Biology and the Keck Center for Behavioral Biology, North Carolina State University, Raleigh, NC 27695 Edited* by Edward O. Wilson, Harvard University, Cambridge, MA, and approved March 23, 2012 (received for review August 24, 2011) Most of the described and probably undescribed species on Earth As for other taxa, richness decreased with latitude (e.g., refs. 13 are insects. Global models of species diversity rarely focus on and 14) (Fig. 1) and there were also strong regional effects on the insects and none attempt to address unknown, undescribed magnitude of diversity. African regions were less diverse than diversity. We assembled a database representing about 13,000 would be expected given their latitude (or climate), the reverse of records for ant generic distribution from over 350 regions that the pattern observed for termites (15, 16) and terrestrial mammals cover much of the globe.

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. -
Thievery in Rainforest Fungus-Growing Ants: Interspecific Assault on Culturing Material at Nest Entrance
Insectes Sociaux (2018) 65:507–510 https://doi.org/10.1007/s00040-018-0632-9 Insectes Sociaux SHORT COMMUNICATION Thievery in rainforest fungus-growing ants: interspecific assault on culturing material at nest entrance M. U. V. Ronque1 · G. H. Migliorini2 · P. S. Oliveira3 Received: 15 March 2018 / Revised: 21 May 2018 / Accepted: 22 May 2018 / Published online: 5 June 2018 © International Union for the Study of Social Insects (IUSSI) 2018 Abstract Cleptobiosis in social insects refers to a relationship in which members of a species rob food resources, or other valuable items, from members of the same or a different species. Here, we report and document in field videos the first case of clepto- biosis in fungus-growing ants (Atta group) from a coastal, Brazilian Atlantic rainforest. Workers of Mycetarotes parallelus roam near the nest and foraging paths of Mycetophylax morschi and attack loaded returning foragers of M. morschi, from which they rob cultivating material for the fungus garden. Typically, a robbing Mycetarotes stops a loaded returning Myce- tophylax, vigorously pulls away the fecal item from the forager’s mandibles, and brings the robbed item to its nearby nest. In our observations, all robbed items consisted of arthropod feces, the most common culturing material used by M. parallelus. Robbing behavior is considered a form of interference action to obtain essential resources needed by ant colonies to cultivate the symbiont fungus. Cleptobiosis between fungus-growing ants may increase colony contamination, affect foraging and intracolonial behavior, as well as associated microbiota, with possible effects on the symbiont fungus. The long-term effects of this unusual behavior, and associated costs and benefits for the species involved, clearly deserve further investigation. -

The Coexistence
Myrmecological News 13 37-55 2009, Online Earlier Natural history and phylogeny of the fungus-farming ants (Hymenoptera: Formicidae: Myrmicinae: Attini) Natasha J. MEHDIABADI & Ted R. SCHULTZ Abstract Ants of the tribe Attini comprise a monophyletic group of approximately 230 described and many more undescribed species that obligately depend on the cultivation of fungus for food. In return, the ants nourish, protect, and disperse their fungal cultivars. Although all members of this tribe cultivate fungi, attine ants are surprisingly heterogeneous with regard to symbiont associations and agricultural system, colony size and social structure, nesting behavior, and mating system. This variation is a key reason that the Attini have become a model system for understanding the evolution of complex symbioses. Here, we review the natural-history traits of fungus-growing ants in the context of a recently published phylo- geny, collating patterns of evolution and symbiotic coadaptation in a variety of colony and fungus-gardening traits in a number of major lineages. We discuss the implications of these patterns and suggest future research directions.

(Hymenoptera: Formicidae: Myrmicinae). Biodiversity Data Journal 4: e10673. doi: 10.3897/BDJ.4.e10673 Abstract Background The fungus-farming ant genus Cyatta (Formicidae: Myrmicinae) is represented by a single species, C. abscondita Sosa-Calvo et al., known from a few localities in Brazil (in the states of Ceará, Minas Gerais, São Paulo and the Distrito Federal), and a single locality in the Misiones province, Argentina. Cyatta is known to occur predominantly in savanna habitats and occasionally in the transition zones between the Atlantic Forest and Cerrado. New information The new records reported here significantly expand the previously known distribution of Cyatta abscondita and provide further support for the intimate relation between this species and the savannas of South America. We report the first occurrence of the genus in southern Brazil (Paraná state) and the westernmost occurrence (Bolivia) of Cyatta abscondita, which extend its distribution approximately 1450 km to the west.

Abstract. This study investigates the evolutionary history of a hyperdiverse clade, the ant subfamily Myrmicinae (Hymenoptera: Formicidae), based on analyses of a data matrix comprising 251 species and 11 nuclear gene fragments. Under both maximum likelihood and Bayesian methods of inference, we recover a robust phylogeny that reveals six major clades of Myrmicinae, here treated as newly defined tribes and occur- ring as a pectinate series: Myrmicini, Pogonomyrmecini trib.n., Stenammini, Solenop- sidini, Attini and Crematogastrini. Because we condense the former 25 myrmicine tribes into a new six-tribe scheme, membership in some tribes is now notably different, espe- cially regarding Attini. We demonstrate that the monotypic genus Ankylomyrma is nei- ther in the Myrmicinae nor even a member of the more inclusive formicoid clade – rather it is a poneroid ant, sister to the genus Tatuidris (Agroecomyrmecinae). -

First Standardized Inventory of Ants (Hymenoptera: Formicidae) in the Natural Grasslands of Paraná: New Records for Southern Brazil
First standardized inventory of ants (Hymenoptera: Formicidae) in the natural grasslands of Paraná: New records for Southern Brazil Weslly Franco¹² & Rodrigo Machado Feitosa¹³ ¹ Universidade Federal do Paraná (UFPR), Departamento de Zoologia (DZOO), Laboratório de Sistemática e Biologia de Formigas (LSBF). Curitiba, PR, Brasil. ² ORCID: 0000-0003-2670-4527. E-mail: [email protected] (corresponding author) ³ ORCID: 0000-0001-9042-0129. E-mail: [email protected] Abstract. Despite the large number of studies investigating ant diversity in Brazilian biomes, no ant-related studies have been carried out in Campos Gerais, a grassland physiognomy in Paraná state. The present study is the first inventory of the ant fauna in one of the few conservation units protecting the Campos Gerais landscape, the Guartelá State Park (PEG). Sixty samples were collected from different habitats within PEG using pitfall traps. Qualitative samples of leaf litter were collected from forest frag- ments and submitted to Winkler extractors. In addition, manual qualitative sampling was carried out in the various physiogno- mies within the PEG. A total of 163 species was collected and sorted into 43 genera and nine subfamilies. Five genera and 28 species were recorded for the first time in the state of Paraná. Out of these, 17 species were also recorded for the first time in the Southern Region of Brazil and two were recorded for the first time to the country. The significant species richness in the PEG and the high number of new records is a strong sign of this ecosystem’s potential to reveal taxonomic novelties. These results suggest that PEG, and the Campos Gerais as a whole, should be the target of greater conservation efforts to preserve native remnants. -
