Structure des communautés de Phanaeini (Coleoptera : Scarabaeidae) de Guyane : étude par échantillonnage massif au piège d’interception. Annales de la Société entomologique de France (N.S.) 53(3): 143-161. DOI:10.1080/00379271.2017.1319294
Résumé [+] [-]Seasonality and community structure of Phanaeini (Coleoptera: Scarabaeidae) in French Guiana : study by mass sampling using large flight interception traps. Phanaeini is a neotropical tribe of scarabs mostly dung or carrion feeders, generally of large size. This paper analyses data collected with large window flight interception traps set on nine forest sites in French Guiana with a primary goal of biotic inventory. The study deals with three main questions: 1) What is the spatial structure of communities and are there some species indicators of secondary forests and others of pristine conditions? 2) What is the temporal structure of the community and is there a stable pattern of seasonality between years and sites? 3) Between close species, is there a temporal asynchrony? Our samples contain more than 9,700 identified specimens, nine complete year series on four sites including a four years continuous survey near Cayenne. We found a significantly lower diversity (Shannon and Simpson index) on the most fragmented and hunted sites. A more equitable repartition of species and a relative abundance of the larger species appear typical of undisturbed sites. Other observations reinforce the hypothesis that there is a fast and huge modification in Phanaeini community structure on the most accessible and disturbed sites. Seasonal pattern shows an abundance peak at the beginning of the rainy season (December or January), a medium abundance during the rainy season with sometimes secondary peaks and a low to very low activity during the dry season. The pattern is rather consistent between years but changes with sampling site. It is however different from the results of other studies using pitfall baited traps in Amazonian and Guyanese forests. These studies show much less clear temporal pattern or no seasonal change. There is no obvious pattern of niche sharing by phenological differences between species. The methodological differences of sampling between baited traps and window flight traps are eventually discussed. Due to its passive way of collecting, interception trap is considered as quite relevant for studying flight activity spatio-temporal patterns of Scarabaeinae. This aspect may explain some differences in seasonality patterns compared to other studies.

Résumé [+] [-]This article introduces the biodiversity survey “Our Planet Reviewed” in the south of French Guiana organized in February-March and August 2015. It has enabled more than 50 scientists to inventory the following groups: Actinopterygii, Amphibia, Annelida, Arachnida, Insecta, Mollusca and Squamata, with a particular effort on diverse and little-known orders, such as Coleoptera, Diptera, Hemiptera and Hymenoptera. The forested area under investigation presents a mosaic of hills and inselbergs, with a wide variety of ecosystems. The main objectives were to discover new species for science, report first records for French Guiana, and establish a baseline inventory for biogeographic studies. The organisation of the field trip and post-field phase are supported by coordinators of major taxonomic groups. Authorisations and associated commitments, including Access and Benefit Sharing (ABS) are specified. The sampling effort, in terms of number and diversity of methods, is certainly the largest ever made in French Guiana over a short period of time. Thirteen different trap types were used including four types of interception traps and nine types of attraction-based traps. Active research methods (13 techniques) and extraction from the substrate (five techniques, including Winkler sieves, emergence from dead wood, etc.) completed the sampling array. The sample processing procedure describes the difference between active collecting and the longer and more complex process of processing massive samples of traps such as window pane flight intercept traps, Malaise traps, colored pan traps and automatic light traps. After a sorting phase that lasted less than a year for most groups, a network of 165 taxonomic experts was mobilized by the coordinators to study the sorted specimens. The data are stored and managed in an observations database and in the database of the collections of the Muséum national d’Histoire naturelle (Paris). Data are widely disseminated, notably in France via the Inventaire national du Patrimoine naturel (INPN) and internationally by the Global Biodiversity Information Facility (GBIF). This introductory article will be supplemented by a second paper, which will analyse research results three years after the survey and assess the effectiveness of the expedition in advancing taxonomic knowledge.
