However, studies on the diversity of arboreal ants are less frequent in the Amazon. In this paper we list arboreal ant species sampled in understory along four transects in a forest remnant in a South Amazonian landscape. The list includes 32 species, of which three (9 %) are new records for the state of Mato Grosso, Brazil, one of these species being sampled for the first time in Brazil. Key words.

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. -
Seed Dispersal Mutualisms Are Essential for the Survival of Diverse Plant Species and Communities Worldwide
ABSTRACT YOUNGSTEADT, ELSA KRISTEN. Neotropical Ant-Gardens: Behavioral and Chemical Ecology of an Obligate Ant-Plant Mutualism. (Under the direction of Coby Schal.) Seed dispersal mutualisms are essential for the survival of diverse plant species and communities worldwide. An outstanding but poorly understood ant-seed mutualism occurs in the Amazonian rainforest, where arboreal ants collect seeds of several taxonomically diverse plant species and cultivate them in nutrient-rich nests, forming abundant hanging gardens known as ant-gardens (AGs). AG ants and plants are dominant members of lowland Amazonian ecosystems, and their interaction is obligate and apparently species-specific. Though established AGs are limited to specific participants, it is unknown at what stage specificity arises. Seed fate pathways in AG epiphytes are undocumented, and the recognition cues that mediate the mutualism are unknown. Here the species specificity of the AG ant-seed interaction is assessed, and chemical cues are characterized that elicit seed- finding and seed-carrying in AG ants. To examine the specificity of the ant-seed interaction, general food baits and seeds of the AG plant Peperomia macrostachya were offered on alternate days at 108 bait stations. Seventy ant species were detected at food baits and could have interacted with AG seeds, but only three species collected P. macrostachya seeds, and 84% of observed seed removal by ants was attributed to C. femoratus. In a separate experiment, arthropod exclusion significantly reduced AG seed removal rates, but vertebrate exclusion did not. Thus species specific seed dispersal, rather than post-dispersal processes, appears to be the primary determinant of the distribution of AG plants. -
Indirect Mutualism: Ants Protect Fig Seeds and Pollen Dispersers from Parasites Ecological Entomology, 2015 K
Ecological Entomology (2015), DOI: 10.1111/een.12215 Indirect mutualism: ants protect fig seeds and pollen dispersers from parasites K. CHARLOTTE JANDÉR1,2,3 1Department of Ecology and Evolutionary Biology, Yale University, New Haven, Connecticut, U.S.A., 2Department of Ecology and Genetics, Evolutionary Biology Centre, Uppsala University, Uppsala, Sweden and 3Smithsonian Tropical Research Institute, Panama City, Panama Abstract. 1. Mutualisms are ubiquitous and ecologically important, but may be particularly vulnerable to exploitation by species outside of the mutualism owing to a combination of an attractive reward and potentially limited defence options. For some mutualisms, ants can offer dynamic and relatively selective protection against herbivores and parasites. 2. The mutualism between fgtreesandtheirpollinatingwasps,akeystonemutualism in tropical forests, is particularly well suited for ant protection because pollinators are protected inside hollow inforescences but parasites are exposed on the outside. 3. In the present study, it was shown that the presence of ants provides a ftness beneft for both the pollinators and the hosting fgtree.Thepresenceofants(i)reducedabortions of developing fgs, (ii) reduced herbivory of fgs, and (iii) reduced parasitic wasp loads, resulting in more pollinators and more seeds in ant-protected fgs. Even when taking costs such as ant predation on emerging pollinators into account, the total ftness increase of hosting ants was threefold for the tree and fvefold for the pollinators. 4. It was further shown that the seemingly most vulnerable parasitic wasps, of the genus Idarnes,haveaspecifcbehaviourthatallowsthemtoevadeantattackwhilecontinuing to oviposit. 5. Ants were present on 79% of surveyed Panamanian fgtrees.Togetherwithprevious studies from the Old World, the results found here imply that ants are both powerful and common protectors of the fgmutualismworldwide. -

Rio Branco, Acre, Brasil IIUniversidade Federal de Lavras. Lavras, Minas Gerais, Brasil IIIUniversidade Federal do Amazonas. Manaus, Amazonas, Brasil IVUniversidade Federal de Viçosa. Florestal, Minais Gerais, Brasil Abstract: Brazil counts with one the largest ant diversity in the world. But, given its continental dimension and uneven scientific development process, there are still several gaps in the knowledge of this biodiversity. This fully applies to research on ant diversity in the state of Acre, southwestern Brazilian Amazon. Since 2014, in Acre, ants are being sampled by Rede BIA project, which aims to cover this gap. Thus, our main goal is to present the status of ant diversity studies in Acre regarding their progress and their contribution to the ant fauna knowledge, based on scientific papers and grey literature. We found 17 studies to Acre, which encompass a time range of 10 years, and a total of 338 species recorded. The studies are concentrated mainly in the southern and eastern parts of the state. Ground pitfall trap is the most used sampling technique. We point out that adding more sites to Rede BIA’s collecting efforts, plus focusing samplings in poorly studied habitats and ecosystems, especially in the western and eastern parts of the state will provide a lot of new data on ant species occurrence to Acre and to Brazil. -

The arthropod fauna inhabiting 90 individuals of three different spe- cies of epiphyte was investigated in the moist lowland forest of the Barro Colorado National Monument in Panama. In total, 3694 arthropods belonging to 89 morpho- species and 19 orders were collected. While arthropod abundance was primarily a function of host plant biomass irrespective of epiphyte species, there were pro- nounced differences in species richness, species composition and guild structure of the arthropod faunas of the three epiphyte species. Although all study plants were growing in close proximity on the same host tree species, there was remarkably little overlap in the species assemblages across epiphyte taxa. The inhabitant species also differed dramatically in their ecological functions, as feeding guild and hunting guild analyses indicated. The influence of plant size, structure and impounded leaf litter onarthropod diversity is discussed. We concludethat epiphytes are microhabitats for a diverse and numerous fauna, and that different species of epiphytes foster both taxonomically and ecologically very distinct arthropod assemblages. KEY WORDS: Barro Colorado Island, bromeliads, guild structure, leaf litter, microclimate, orchids, plant size, spiders INTRODUCTION Ever since Erwin (1983) published his estimates of global species richness, researchers have been trying to unravel the mechanisms behind the extraordin- ary biotic diversity of tropical forest canopies. -

Predatory Ant (Labidus Coecus)
Beneficial Species Profile Photo credit: April Nobile, California Academy of Sciences (Specimen: CASENT0104978; from https://www.antweb.org) Common Name: Predatory Ant (Legionary ants; New World army ants) Scientific Name: Labidus coecus Order and Family: Order Hymenoptera; Family Formicidae Size and Appearance: Length (mm) Appearance Egg Larva/Nymph Adult Workers range These ants have a prominent stinger, 12 segmented from 3 – 10 mm antennae without a club, and a two-part waist. The workers are polymorphic and lack eyes and dorsal spines. The workers are red with a smooth and shiny face. Pupa (if applicable) Type of feeder (Chewing, sucking, etc.): Chewing Host(s): Because this predatory ant primarily forages through the ground, it has a more generalized diet but feeds mostly on the brood of other ants and will feed on scavenged items, including human food scraps. Description of Benefits (predator, parasitoid, pollinator, etc.): This army ant is nearly completely subterranean and its raids may foster ant species diversity, which benefits the ecosystem and may control pest insect species in agricultural systems. They do prey on screwworm larvae, which are a pest of livestock. Related species have been used to do this in China for hundreds of years. This predatory ant is found in North, Central, and South America. In the USA, this ant is found in Arkansas, Oklahoma, Louisiana, and Texas. References: Gotwald, W.H. (1995).
