Vertical stratification of insect abundance and species richness in an Amazonian tropical forest

Scientific Reports (2022)

Dalton de Souza Amorim Brian V. Brown Danilo Bôscolo Rosaly Ale‐Rocha Deivys M. Alvarez García

Abstract Tropical forests are among the most biodiverse biomes on the planet. Nevertheless, quantifying the abundance and species richness within megadiverse groups is a significant challenge. We designed a study to address this challenge by documenting the variability of the insect fauna across a vertical canopy gradient in a Central Amazonian tropical forest. Insects were sampled over two weeks using 6-m Gressitt-style Malaise traps set at five heights (0 m–32 m–8 m intervals) on a metal tower in a tropical forest north of Manaus, Brazil. The traps contained 37,778 specimens of 18 orders of insects. Using simulation approaches and nonparametric analyses, we interpreted the abundance and richness of insects along this gradient. Diptera, Hymenoptera, and Coleoptera had their greatest abundance at the ground level, whereas Lepidoptera and Hemiptera were more abundant in the upper levels of the canopy. We identified species of 38 of the 56 families of Diptera, finding that 527 out of 856 species (61.6%) were not sampled at the ground level. Mycetophilidae, Tipulidae, and Phoridae were significantly more diverse and/or abundant at the ground level, while Tachinidae, Dolichopodidae, and Lauxaniidae were more diverse or abundant at upper levels. Our study suggests the need for a careful discussion of strategies of tropical forest conservation based on a much more complete understanding of the three-dimensional distribution of its insect diversity.

Checklist of the dipterofauna (Insecta) from Roraima, Brazil, with special reference to the Brazilian Ecological Station of Maracá

Papéis Avulsos de Zoologia (2022)

Paula Raile Riccardi Diego Aguilar Fachin Rosaly Ale‐Rocha Edna Maria Amaral Dalton de Souza Amorim

Roraima is a Brazilian state located in the northern portion of the Amazon basin, with few studies regarding its biodiversity. The Ecological Station of Maracá (Brazil, state of Roraima) harbors the third largest Brazilian pluvial island and is composed of a transitional landscape of savanna and Amazon rainforest components. Despite its ecological importance and strategic localization, few studies covered the dipterofauna of this locality. An updated checklist addressing 41 families of true flies (Diptera) occurring in Roraima is presented based on the literature and the specimens collected during a field expedition that occurred in 2015. This checklist brings several improvements such as new records of 165 taxa to the state of Roraima, 29 taxa to Brazil, and 259 morphotypes, mostly likely representing undescribed species.

Insect (Hexapoda) diversity in the oceanic archipelago of Fernando de Noronha, Brazil: updated taxonomic checklist and new records

Revista Brasileira de Entomologia (2020)

José Albertíno Rafael Francisco Limeira-de-Oliveira Roger William Hutchings Gil Felipe Gonçalves Miranda ALBERTO MOREIRA DA SILVA NETO

Hexapods, commonly known as insects, are a neglected taxonomic group in the Fernando de Noronha archipelago, with unanswered questions about their species richness and the ecological processes in which they are involved (e.g., colonization, introduction, establishment, and extinction). Herein, we provide an updated Hexapod checklist with current nomenclatural combinations. The entomofauna of the Fernando de Noronha archipelago is currently composed of 453 species in 21 orders. The orders, and their respective number of species, are: Blattaria (9), Coleoptera (118), Collembola (29), Dermaptera (3), Diplura (1), Diptera (134), Embioptera (1), Hemiptera (29), Hymenoptera (59), Isoptera (2), Lepidoptera (25), Mantodea (1), Neuroptera (3), Odonata (5), Orthoptera (11), Phasmatodea (1), Phthiraptera (6), Psocoptera (3), Siphonaptera (1), Thysanoptera (10), and Zygentoma (2). The archipelago has 263 new taxon records (family + genera + species). Thirty-eight species (3.39%) were described from local specimens and most of them are likely endemic species. This study more than doubles our knowledge (from the previous 190 records) of the entomofauna in this large Brazilian archipelago. This study also provides a baseline for studies on its conservation status and for implementing future environmental management programs.

Vertical stratification of Diptera abundance and species richness in an Amazonian tropical forest

Research Square (Research Square) (2021)

Dalton S. Amorim Brian V. Brown Danilo Bôscolo Rosaly Ale‐Rocha Deivys M. Alvarez García

Abstract Measuring species richness of tropical forests is a major challenge. Such measurement is a key information in many senses, from an evolutionary perspective to conservation of threatened, fragile habitats. Data has gradually shown that the canopy of tropical forest is a hugely complex component of the forest, but a precise assessment of the diversity of megadiverse groups in the canopy is still wanting. We collected large samples of insects were along a period of two weeks using 6-meter Gressitt-style Malaise traps set at five heights on a metal tower in a tropical forest north of Manaus—one trap at the ground level, one trap above the canopy (32 m) and three traps at intermediate levels (8, 16 and 24 m). The samples contained 37,778 specimens belonging to 18 order of insects. Fifty-seven families of flies (Diptera) were found, 39 of which were identified to 368 genera and 856 species. The species of these 39 families of flies fit into eight patterns of vertical distribution of abundance and species richness of the fauna, with patterns of one or two peaks of species at different levels. A total of 527 (61.6%) of the 856 fly species recognized in the samples were not collected at the ground level. The canopy-associated species of Diptera showed a high species richness and a relatively low abundance indicating that they represent vulnerable components of tropical diversity. The biology of the flies families and genera we collected in the canopy suggest that the evolution of flies went through a unique process: independent clades of Diptera explored in different ways the resources originated along the very evolution of the angiosperm forest canopy along the early Cenozoic. Unlike other primarily phytophagous groups of insects, flies radiated into a large array of biologies associated with the canopies: parasitoids, hematophagous, phytosaprophagous, kleptoparasites, sap feeders, gall-makers etc. The results only stress the need of additional strategies to protect this diversity.

Heloísa Fernandes Flores Gabriela Pirani Stephen D. Gaimari Dalton de Souza Amorim

Two new species of Neotraginops Prado (Neotraginops fachini sp. nov. and Neotraginops arikemi sp. nov.) are added to the known Neotropical diversity of the Traginopinae (Odiniidae), and the range is expanded for Neotraginops mexicanus Herndez-Ortiz Dzul-Cauich. A key to the species of the genus is provided. Along with descriptions, photographs and detailed illustrations of the male terminalia are included for the new species.

Checklist of true flies (Diptera) from San Luis Obispo County, California, U.S.A.: an outcome of the Fly School II taxonomic workshop

The Pan-Pacific Entomologist (2022)

C. Scott Clem Brittany D. Wingert Andrea Kautz Amanda Roe Teagan Mulford

True flies (Diptera) are a hyper-diverse group of insects which are considerably under-studied compared to many other organisms. Here we report a list of taxa collected during the 2019 Fly School held in San Luis Obispo County, California, a region of the California Floristic Province biodiversity hotspot. From June 20th to July 6th, an international team of 35 entomologists collected and identified Diptera at 17 main sites across the county. The team identified a total of 68 families, 188 genera, and 133 species/species groups. Of these, we uncovered 21 potential new county records for California, expanding knowledge of geographic distributions for these taxa. We discuss the strengths and limitations of this list and suggest ideas for streamlining the publication of similar lists for other specialized taxonomic workshops.
