Item Arthropod diversity in a tropical forest.(2012) Basset, Yves; Cizek, Lukas; Cuénoud, Philippe; Didham, Raphael K.; Guilhaumon, François; Missa, Olivier; Novotny, Vojtech; Ødegaard, Frode; Roslin, Tomas; Schmidl, Jürgen; Tishechkin, Alexey K.; Winchester, Neville N.; Roubik, David W.; Aberlenc, Henri Pierre; Bail, Johannes; Barrios, Héctor; Bridle, Jonathan R.; Meneses, Gabriela Castaño; Corbara, Bruno; Curletti, Gianfranco; Rocha, Wesley Duarte da; Bakker, Domir De; Delabie, Jacques Hubert Charles; Dejean, Alain; Fagan, Laura L.; Floren, Andreas; Kitching, Roger L.; Medianero, Enrique; Miller, Scott E.; Oliveira, Evandro Gama de; Orivel, Jérôme; Pollet, Marc; Rapp, Mathieu; Ribeiro, Sérvio Pontes; Roisin, Yves; Schmidt, Jesper B.; Sørensen, Line L.; Leponce, MauriceMost eukaryotic organisms are arthropods. Yet, their diversity in rich terrestrial ecosystems is still unknown. Here we produce tangible estimates of the total species richness of arthropods in a tropical rainforest. Using a comprehensive range of structured protocols, we sampled the phylogenetic breadth of arthropod taxa from the soil to the forest canopy in the San Lorenzo forest, Panama. We collected 6144 arthropod species from 0.48 hectare and extrapolated total species richness to larger areas on the basis of competing models. The whole 6000-hectare forest reserve most likely sustains 25,000 arthropod species. Notably, just 1 hectare of rainforest yields >60% of the arthropod biodiversity held in the wider landscape. Models based on plant diversity fitted the accumulated species richness of both herbivore and nonherbivore taxa exceptionally well. This lends credence to global estimates of arthropod biodiversity developed from plant models.Item IBISCA-Panama, a large-scale study of arthropod beta-diversity and vertical stratification in a lowland rainforest : rationale, study sites and field protocols.(2007) Basset, Yves; Corbara, Bruno; Barrios, Héctor; Cuénoud, Philippe; Leponce, Maurice; Aberlenc, Henri Pierre; Bail, Johannes; Bito, Darren; Bridle, Jonathan R.; Castaño Meneses, Gabriela; Cizek, Lukas; Cornejo, Aydee; Curletti, Gianfranco; Delabie, Jacques Hubert Charles; Dejean, Alain; Didham, Raphael K.; Dufrêne, Marc; Fagan, Laura L.; Floren, Andreas; Frame, Dawn M.; Hallé, Francis; Hardy, Olivier J.; Hernandez, Andrés; Kitching, Roger L.; Lewinsohn, Thomas M.; Lewis, Owen T.; Medianero, Enrique; Missa, Olivier; Mitchell, Andrew W.; Mogia, Martin; Novotny, Vojtech; Ødegaard, Frode; Oliveira, Evandro Gama de; Orivel, Jérôme; Ozanne, laire M.

Here, we present the rationale of the programme, describe the study sites, and outline field protocols. In the San Lorenzo Protected Area of Panama, twelve 20 x 20 m sites, all less than 2 km apart, were surveyed for plants and arthropods, from the ground to the upper canopy. Access to the canopy and its fauna was facilitated by fogging, single-rope techniques and a variety of devices such as a canopy crane, the “SolVin-Bretzel” canopy raft, the canopy bubble and Ikos. IBISCA-Panama represented the first attempt to combine these complementary techniques of canopy access in a large-scale investigation. Such techniques provided spatial replication during initial field work performed in September-October 2003. Temporal replication across seasons consisted of subsequent field work of varying intensity during dry, early wet and late wet periods in 2004. Arthropods were surveyed using 14 different protocols targeting the soil, litter, understorey, mid-canopy and upper canopy habitats. These protocols included: WINKLER sifting; BERLESE-TULLGREN; hand-collecting of galls and social insects; fogging; beating; woodrearing; baits; and various types of traps such as pitfall, small and large flight-interception, sticky, light, and Malaise traps. Currently, analyses of arthropod distribution in this forest concentrate on a set of 63 focal taxa representing different phylogenies and lifehistories. IBISCA-Panama may be considered as a model for largescale research programmes targeting invertebrate biodiversity. Its collaborative modus operandi can be applied to answer a variety of pressing ecological questions related to forest biodiversity, as evidenced by the recent development of further IBISCA programmes in other parts of the world.Item Subtle structures with not-so-subtle functions : a data set of arthropod constructs and their host plants.(2022) Pereira, Cássio Cardoso; Novais, Samuel Matos Antunes de; Silva Júnior, Milton Barbosa da; Negreiros, Daniel; Souza, Thiago Gonçalves; Roslin, Tomas; Marquis, Robert; Marino, Nicholas; Novotny, Vojtech; Orivel, Jérôme; Sui, Shen; Aires, Gustavo; Antoniazzi Júnior, Reuber Lana; Cruz, Wesley Francisco Dáttilo da; Breviglieri, Crasso; Busse, Annika; Gibb, Heloise; Izzo, Thiago Junqueira; Kadlec, Tomas; Kemp, Victoria; Becker, Monica Kersch; Knapp, Michal; Kratina, Pavel; Luke, Rebecca; Majnaríc, Stefan; Maritz, Robin; Martins, Paulo Mateus; Mendesil, Esayas; Michalko, Jaroslav; Mrazova, Anna; Períc, Mirela Sertíc; Petermann, Jana; Ribeiro, Sérvio Pontes; Sam, Katerina; Trzcinski, M.

M.; Teder, Tiit; Videla, Martin; Viljur, Mari-Liis; Koricheva, Julia; Fernandes, Geraldo Wilson Afonso; Romero, Gustavo Quevedo; Cornelissen, Tatiana GarabiniThe construction of shelters on plants by arthropods might influence other organisms via changes in colonization, community richness, species composi- tion, and functionality. Arthropods, including beetles, caterpillars, sawflies, spiders, and wasps often interact with host plants via the construction of shel- ters, building a variety of structures such as leaf ties, tents, rolls, and bags; leaf and stem galls, and hollowed out stems. Such constructs might have both an adaptive value in terms of protection (i.e., serve as shelters) but may also exert a strong influence on terrestrial community diversity in the engineered and neighboring hosts via colonization by secondary occupants. Although different traits of the host plant (e.g., physical, chemical, and architectural features) may affect the potential for ecosystem engineering by insects, such effects have been, to a certain degree, overlooked. Further analyses of how plant traits affect the occurrence of shelters may therefore enrich our understanding of the organizing principles of plant-based communities. This data set includes more than 1000 unique records of ecosystem engineering by arthropods, in the form of structures built on plants. All records have been published in the liter- ature, and span both natural structures (91% of the records) and structures artificially created by researchers (9% of the records). The data were gathered between 1932 and 2021, across more than 50 countries and several ecosystems, ranging from polar to tropical zones. In addition to data on host plants and engineers, we aggregated data on the type of constructs and the identity of inquilines using these structures. This data set highlights the importance of these subtle structures for the organization of terrestrial arthropod communi- ties, enabling hypotheses testing in ecological studies addressing ecosystem engineering and facilitation mediated by constructs.
