Abstract

The presence of Daceton boltoni in Cotriguaçu municipality, state of Mato Grosso, southern Amazon is reported. Workers of D. boltoni were collected manually in nests on the branches of three Caxeta trees (Simarouba amara Aubl. - Simaroubaceae) from a reforestation area. In the same location where D. boltoni as recorded, Daceton armigerum (Latreille 1802) workers have also been collected, corroborating the hypothesis that these are sympatric species. This is the first record of the occurrence of this species in Mato Grosso state and the second in the Brazilian Amazon.

American forests (Silvestre et al. 2003; Fernández and
Sendoya 2004; Goitía and Jaffé 2009). In 2008, a review on
the referred genus revealed a new species: Daceton boltoni

no reports on the new species. However, in May (2011)
D. boltoni were reported nesting in branches of three
Caxeta trees (Simarouba amara Aubl. - Simaroubaceae)
from a reforestation area in Northwest Mato Grosso
(Brazil), on São Nicolau Farm (09°51’16” S, 58°14’57”

(Voucher: ABAM - E 116). In the same location where D.
boltoni was recorded in the present report, workers of D.
armigerum have also been collected on the litter extracted
with Winkler and on the understory with beating tray
method (Monteiro et al. 2011). This reinforces the
hypothesis that they are sympatric species as proposed by
Azorsa and Sosa-Calvo (2008). Because D. boltoni has been
known to occur only in Loreto (Peru) and Manaus (Brazil)
(Azorsa and Sosa-Calvo 2008), this new occurrence,
recorded about 800 km far away from the closest point
(Manaus), is a considerable increase in the distribution of
this species of which little is known.

This study presents a preliminary inventory of butterflies (Lepidoptera: Papilionoidea) in the Rio Ronuro Ecological Station in Brazil. Butterflies were sampled in eight plots dis�tributed in three sites located between the Municipality of Nova Ubiratã and Paranatin�ga and Santiago do Norte. We sampled 30 species of butterflies, in four families, Nymph�alidae, Pieridae, Papilionidae e Riodinidae. The sampling period was short and lacking temporal repetitions, however considering the low numbers of traps installed (36) and sampling during the rainy season our results indicate a large potential diversity of butter�flies to be explored in the future in the station.

Arthropods are important components of edaphic environments, being responsible for numerous processes related to the decomposition and cycling of matter. Studies on their diversity are important for understanding the ecosystem dynamics. This study aimed to evaluate the composition of the edaphic community of arthropods, mainly arachnids, in a Cerrado-Amazônia transition area at the Rio Ronuro Ecological Station, in Nova Ubiratã, Mato Grosso. Arthropods were sampled in October/November 2016 and in February/March 2017, using pitfall traps. Opiliones were collected manually. As a result 9,611 arthropods were obtained, distributed among Hexapoda, Arachnida, Diplopoda and Chilopoda and 21 taxonomic orders. Hymenoptera (4,984 ind.; 51.9%), Diptera (2,299 ind.; 23.9%), Collembola (660 ind.; 6.9%), Isoptera (581 ind.; 6%) and Coleoptera (435 ind.; 4.5%) predominated. Among the spiders (220 ind.; 2.3%) were identified 24 families and nine behavioral guilds. Zodariidae (60 ind.; 28%), Lycosidae (51 ind.; 22%) and Theridiidae (32 ind.; 14%) predominated. The Opiliones (15 ind.; 0.2%) were Cosmetidae (10 ind.; 66.6%), Stygnidae (3 ind.; 20%) and Manaosbiidae (2 ind.; 13.4%). The results indicate that Rio Ronuro ESEC presents considerable edaphic biodiversity, corroborating its importance as an area for the conservation of Southern Amazonia.

With a territory of 90,680,600 hectares, the state of Mato Grosso possesses a broad range of natural beauty and rich biodiversity and currently houses 46 state conservation units that encompass 3.2 million hectares. A significant part of this biodiversity, however, remains un�known due to limited knowledge generation and dissemination. Rio Ronuro Ecological Station is one of five existing state ecological stations in Mato Grossso. It stands out for being located in the central region of the state, specifically comprising the transition between the Cerrado and Amazonia biomes (area with Savanna/Seasonal Forest/Ombrophilous Forest), bestowing it with the potential to harbor rich biodiversity and thus unique relevance within State System of Conservation Units. In compliance with the objective for which Rio Ronuro Ecological Station was created – protection of existing ecosystems, development of scientific research and conservation ed�ucation – State Secretary of Environment of Mato Grosso (SEMA-MT), together with the technical cooperation of Amazon Region Protected Areas Program (ARPA) and researchers of Federal University of Mato Grosso (UFMT), and support from Biodiversity Research Pro�gram (PPBIO), contributed efforts to survey and catalog the station’s flora and fauna. Scientific research developed in the conservation unit has broadened knowledge of biodiver�sity, provided training for students and local community agents, encouraged bioprospecting studies of species with potential that occur in the region, and made this publication possi�ble, which brings together all the systematic studies carried out to date. The knowledge gathered in this work will contribute to the processes of environmental edu�cation and conservation of biodiversity, as well as provide academic information for society in general. This knowledge will support the decision-making process for public policies for Rio Ronuro Ecological Station, enable its valorization and acknowledge the ecological pro�cesses that maintain it.

Strumigenys fairchildi Brown, 1961 is recorded for the first time in Brazil. This ant species was previously known only from a few specimens collected in Costa Rica, Panama and Ecuador. The worker S. fairchildi was collected at the Parque Estadual do Cristalino, a continuous area of Amazon tropical rain forest protected for biodiversity conservation in the municipality of Novo Mundo, Mato Grosso state. In addition, we present a distribution map and high-resolution images of the worker.

In this paper we list the ant species collected in both remaining forests and urban areas in a South Amazonian landscape. The list includes 102 species, of which 29 are new records for the state of Rondônia, Brazil. This work demonstrates the gap in ant biodiversity surveys for Meridional Amazon as well as encouraging further research in this region.

Gnamptogenys vriesi Brandão and Lattke is a rarely collected ant, which was originally described based on a worker and a dealated queen collected in Morona-Santiago province, Ecuador. After the original description, only a few specimens were collected in the Ecuadorian territory. In this paper, we report the first record of G. vriesi in Brazil, which results in a significant extension of its distribution previously considered restricted to Ecuador. In addition, we provide images and a distribution map for the species.

Although several studies have shown that ants can recognize chemical cues from their host plants in ant-plant systems, it is poorly demonstrated in ant gardens (AGs). In this interaction, ant species constantly interact with various epiphyte species. Therefore, it is possible to expect a convergence of chemical signals released by plants that could be acting to ensure that ants are able to recognize and defend epiphyte species frequently associated with AGs. In this study, it was hypothesized that ants recognize and differentiate among chemical stimuli released by AG epiphytes and non-AG epiphytes. We experimentally simulated leaf herbivore damage on three epiphyte species restricted to AGs and a locally abundant understory herb, Piper hispidum, in order to quantify the number of recruited Camponotus femoratus (Fabricius) defenders. When exposed to the AG epiphytes Peperomia macrostachya and Codonanthe uleana leaves, it was observed that the recruitment of C. femoratus workers was, on average, respectively 556% and 246% higher than control. However, the number of ants recruited by the AG epiphyte Markea longiflora or by the non-AG plant did not differ from paper pieces. This indicated that ants could discern between chemicals released by different plants, suggesting that ants can select better plants. These results can be explained by evolutionary process acting on both ants’ capability in discerning plants’ chemical compounds (innate attraction) or by ants’ learning based on the epiphyte frequency in AGs (individual experience). To disentangle an innate behavior, a product of classical coevolutionary process, from an ant’s learned behavior, is a complicated but important subject to understand in the evolution of ant-plant mutualisms.

Even though Colombia has high levels of ant species richness in the Neotropical region, this richness continues to increase. New records of the ant subfamilies Amblyoponinae, Dolichoderinae, Dorylinae, Myrmicinae, and Ponerinae are presented. Two species of Fulakora, two species of Azteca, one species of Cylindromyrmex, 25 species of Myrmicinae belonging to 12 genera (Acanthognathus, Basiceros, Daceton, Eurhopalothrix, Hylomyrma, Mycetomoellerius, Mycetophylax, Mycocepurus, Octostruma, Pheidole, Rogeria, and Talaridris), and one species of Leptogenys are registered for the first time for Colombia. Five species are new records for South America. For each species, the geographical distance of the record closest to the Colombian locality is offered. Several factors, such as access to previously unexplored conserved areas, sampling techniques that cover heterogeneous microhabitats such as leaf litter, and many more taxonomic researches have allowed the knowledge of ant fauna in Colombia to continue growing.

Ant fauna (Hymenoptera-Formicidae) from a fragment of Atlantic Forest in Southeastern Brazil. Mata do Krambeck is a tropical urban environmental reserve of socioenvironmental importance, being one of the most threatened biomes in the world, and its current area is no more than 12% of the original size, composed mostly of fragments with variable length, usually small. One of those fragments, called Sítio Malícia, was acquired by Federal University of Juiz de Fora for the deployment of the Botanical Garden. Considering that Mata do Krambeck represented over the years an important regional wildlife refuge, researchers have been working to know its biodiversity, with this work being the first to survey the ants fauna. To do that, samples were collected monthly in twelve months, using pitfall traps installed in three tracks inside the forest. The ants collected were screened at the Arthropod Laboratory of the Department of Zoology of UFJF and identified to genera using dichotomous keys. A total of 4232 ants were collected, belonging to the genera Acromirmex, Atta, Camponotus, Cephalotes, Hypoponera, Pachycondila, Pheidole and Solenopsis. There is a great diversity of ants on site, which was expected second analyzed bibliographies. Resumo. A Mata do Krambeck é uma reserva ambiental urbana tropical de importância sócio-ambiental, sendo um dos biomas mais ameaçados do mundo e seus remanescentes somam não mais de 12% da área original, sendo em sua maioria compostos por fragmentos de tamanhos variáveis, em geral pequenos. Um destes fragmentos, chamado Sítio Malícia, foi adquirido pela Universidade Federal de Juiz de Fora para a implantação do Jardim Botânico. Considerando que a Mata do Krambeck representou ao longo dos anos importante refúgio de animais da fauna silvestre regional, pesquisadores têm trabalhado no sentido de conhecer os diversos grupos, sendo este trabalho o primeiro a pesquisar a mirmecofauna. Para isso foram realizadas coletas mensais, durante 12 meses, com a utilização de armadilhas tipo pitfall instaladas em três trilhas no interior da mata.

A recuperação da biodiversidade de áreas degradadas é foco prioritário em Biologia da Conservação. Nossos dados preliminares sugerem que ref lorestamentos de Teca abrigam baixos números e baixa similaridade de espécies de formigas em relação a f lorestas não perturbadas. Isto pode ser explicado pela pouca idade e à inexistência de um sub-bosque nesses ref lorestamentos. O emprego de outras espécies vegetais em ref lorestamentos pode ser mais interessante para a recuperação da biodiversidade.

The goal of the study was to detect genetic variability in Brazilian nuts parent trees through parameters estimation and genetic gains for the following indexes: fruit weight (g) seed weight per fruit (g) and number of seeds per fruit at species pre-improvement. Ninety (90) open pollination parent trees were used, 30 of which being of each type, locally called "rajada", "mirim" and "rosa" at the Cotriguacu municipality, Northeastern of Mato Grosso State. A completely randomized design was used, with 90 treatments (parent trees) and six fruits per parcel with their respective seeds. Variables were analyzed using the method of mixed univariate additive linear model from the software SELEGEN-REML/BLUP. Individual heritability coefficients in the broad sense for total genotypic effects (0,21, 0,14 e 0,34) for fruit weight (g) seed weight per fruit (g) and number of seeds per fruit (g) respectively, are considered moderate for the two first indexes and high for number of seeds per fruit, suggesting substantial genetic control. Selection of the 10 best provenances and parent trees showed predominance of the "rosa" type, allowing substantial genetic gains of at least 24,16% for fruit weight (g), 27,44% for seed weight per fruit and 16,92% for the number of seeds per fruit. The remarkable values for the "rosa" type suggest utilization of such germoplasms in genetic improvement programs of this species in the following evaluations. The results also point out the possibility of obtaining intraspecific hybrids for desirable characteristics.

Este capítulo caracteriza, en términos generales, la comuni-dad de hormigas que habita las áreas del Cerrado de América del Sur y propone un modelo para la clasificación de la comunidad de hormigas en la forma de gremios. La posibilidad de encuadrar a los invertebrados en categorías funcionales transforma a este grupo de organismos particularmente importante en la evaluación del estado y condición del ambiente, principalmente debido a la abundancia relativamente alta y su capacidad de respuesta a las modificaciones en la estructura de los sistemas naturales. Con la descripción de la composición de los gremios reconocidos tenemos en las manos una herramienta que nos permite realizar comparaciones funcionales entre composiciones de es-pecies de diferentes ambientes, no solamente tomando en consideración una lista de especies por localidad, sino también confrontando los modelos estructurales de los gremios; revelando, de esta forma, diferencias en la ecología de las comunidades observadas. Presentamos inicialmente en este capítulo una breve des-cripción del Cerrado del altiplano central Suramericano, con algunos comentarios sobre la ecología de las hormigas de este bioma. Los estudios sobre la composición de los gremios de hormigas fueron realizados en tres etapas. En la primera hicimos un análisis de la influencia de las interacciones comportamentales entre las especies de hormigas que visitan cebos atractivos, con la categorización de los comportamientos de dominancia y agresividad. En la segunda etapa consideramos el levantamiento faunístico realizado en siete localidades del Cerrado, utilizando diversos métodos de muestreos aplicados para hormigas que habitan el suelo (Bestelmeyer et al. 2000) y colectas cualitativas para la vege-tación y para las formas aladas. En la tercera etapa presentamos la categorización de las especies de hormigas del Cerrado en grupos funcionales y sugerimos una forma de clasificación de los gremios utilizando criterios morfológicos y comportamentales dentro de categorías ecológicas, comentando las posibles aplicaciones de este estudio en programas de monitoreo ambiental y en el soporte a las investigaciones que apuntan al estudio de la biodiversidad en los ambientes tropicales. La elección del Cerrado como área de investigación se realizo en función de este bioma que esta desapareciendo.

We evaluated the hypothesis that the abundance and species distribution of two different kinds of myrmecophilous plants is influenced differently by the ant diversity and abundance. In eight different natural forests in Venezuela we estimated the species richness and abundance of plants, ants on the soil and on the canopy, the leaf damage of plants and soil nutrients. The main results of the study show that plants with domatia (PD) and plants with extrafloral nectaries (PEFN) have different relationships with ants and suffer from different ecological constraints. PD attract a more specific group of ants than PEFN. Our results are consistent with the hypothesis that domatia are adaptations that help plants to increase rare nutrient uptake rather than for herbivore defense. We found that PEFN attract a larger variety of ant species than PD, and ant abundance seems to limit the ecological range of PEFN. The attraction of ants as a mechanism to reduce herbivory, as done by PEFN, does not seem to be superior to alternative anti-herbivore mechanisms used by other plants. Contrary to many former studies, we found that ants are generally more diverse on the soil compared to canopies.
