RESUMO

Research on decomposer communities has traditionally focused on plant litter or deadwood. Even though carrion forms highly nutrient-rich necromass that enhance ecosystem heterogeneity, the factors influencing saprophytic communities remain largely unknown. For deadwood, experiments have shown that different drivers determine beetles (i.e., decay stage, microclimate, and space), fungi (i.e., decay stage and tree species) and bacteria (decay stage only) assemblages. To test the hypothesis that similar factors also structure carrion communities, we sampled 29 carcasses exposed for 30 days that included Cervus elaphus (N = 6), Capreolus capreolus (N = 18), and Vulpes vulpes (N = 5) in a mountain forest throughout decomposition. Beetles were collected with pitfall traps, while microbial communities were characterized using amplicon sequencing. Assemblages were determined with a focus from rare to dominant species using Hill numbers. With increasing focus on dominant species, the relative importance of carcass identity on beetles and space on bacteria increased, while only succession and microclimate remained relevant for fungi. For beetle and bacteria with focus on dominant species, host identity was more important than microclimate, which is in marked contrast to deadwood. We conclude that factors influencing carrion saprophytic assemblages show some consistency, but also differences from those of deadwood assemblages, suggesting that short-lived carrion and long-lasting deadwood both provide a resource pulse with different adaptions in insects and microbes. As with deadwood, a high diversity of carcass species under multiple decay stages and different microclimates support a diverse decomposer community.

RESUMO

Dung beetles are important actors in the self-regulation of ecosystems by driving nutrient cycling, bioturbation, and pest suppression. Urbanization and the sprawl of agricultural areas, however, destroy natural habitats and may threaten dung beetle diversity. In addition, climate change may cause shifts in geographical distribution and community composition. We used a space-for-time approach to test the effects of land use and climate on α-diversity, local community specialization (H 2') on dung resources, and γ-diversity of dung-visiting beetles. For this, we used pitfall traps baited with four different dung types at 115 study sites, distributed over a spatial extent of 300 km × 300 km and 1000 m in elevation. Study sites were established in four local land-use types: forests, grasslands, arable sites, and settlements, embedded in near-natural, agricultural, or urban landscapes. Our results show that abundance and species density of dung-visiting beetles were negatively affected by agricultural land use at both spatial scales, whereas γ-diversity at the local scale was negatively affected by settlements and on a landscape scale equally by agricultural and urban land use. Increasing precipitation diminished dung-visiting beetle abundance, and higher temperatures reduced community specialization on dung types and γ-diversity. These results indicate that intensive land use and high temperatures may cause a loss in dung-visiting beetle diversity and alter community networks. A decrease in dung-visiting beetle diversity may disturb decomposition processes at both local and landscape scales and alter ecosystem functioning, which may lead to drastic ecological and economic damage.

RESUMO

In contrast to other necromass, such as leaves, deadwood, or dung, the drivers of insect biodiversity on carcasses are still incompletely understood. For vertebrate scavengers, a richer community was shown for randomly placed carcasses, due to lower competition. Here we tested if scavenging beetles similarly show a higher diversity at randomly placed carcasses compared to easily manageable fixed places. We sampled 12,879 individuals and 92 species of scavenging beetles attracted to 17 randomly and 12 at fixed places exposed and decomposing carcasses of red deer, roe deer, and red foxes compared to control sites in a low range mountain forest. We used rarefaction-extrapolation curves along the Hill-series to weight diversity from rare to dominant species and indicator species analysis to identify differences between placement types, the decay stage, and carrion species. Beetle diversity decreased from fixed to random locations, becoming increasingly pronounced with weighting of dominant species. In addition, we found only two indicator species for exposure location type, both representative of fixed placement locations and both red listed species, namely Omosita depressa and Necrobia violacea. Furthermore, we identified three indicator species of Staphylinidae (Philonthus marginatus and Oxytelus laqueatus) and Scarabaeidae (Melinopterus prodromus) for larger carrion and one geotrupid species Anoplotrupes stercorosus for advanced decomposition stages. Our study shows that necrophilous insect diversity patterns on carcasses over decomposition follow different mechanisms than those of vertebrate scavengers with permanently established carrion islands as important habitats for a diverse and threatened insect fauna.

RESUMO

The occurrence of histerids in Lebanon has received little specific attention. Hence, an aim to enrich the knowledge of this coleopteran family through a survey across different Lebanese regions in this work. Seventeen species belonging to the genera Atholus Thomson, 1859, Hemisaprinus Kryzhanovskij, 1976, Hister Linnaeus, 1758, Hypocacculus Bickhardt, 1914, Margarinotus Marseul, 1853, Saprinus Erichson, 1834, Tribalus Erichson, 1834, and Xenonychus Wollaston, 1864 were recorded. Specimens were sampled mainly with pitfall traps baited with ephemeral materials like pig dung, decayed fish, and pig carcasses. Several species were collected by sifting soil detritus, sand cascading, and other specialized techniques. Six newly recorded species for the Lebanese fauna are the necrophilous Hister sepulchralis Erichson, 1834, Hemisaprinus subvirescens (Ménétriés, 1832), Saprinus (Saprinus) externus (Fischer von Waldheim, 1823), Saprinus (Saprinus) figuratus Marseul, 1855, and Saprinus (Saprinus) niger (Motschulsky, 1849) all associated with rotting fish and dung, and the psammophilous Xenonychus tridens (Jacquelin du Val, 1853). With the exception of Hister sepulchralis, all these taxa belong to the Saprininae subfamily. A most likely undescribed species of Tribalus (Tribalus) (Tribalinae) has also been collected in detritus at wet places near rivers in Lebanon. Because of the complexity of the genus Tribalus, with possible numerous new species present in the circum-Mediterranean area, the Lebanese species is not described herein, pending a revision of the genus. This study advocates further research aimed at improving taxonomic and ecological knowledge of this coleopteran family in Lebanon. The number of Histeridae species currently known from Lebanon stands at 41; a key to all species including images is included.

RESUMO

Many histerid beetles are necrophilous on carrion during both active and advanced stages of decomposition. In this study, 13 species of Saprinus were recorded on carrion from Lebanon, containing eight that are new for the Lebanese fauna. The following Saprinus species are newly recorded from Lebanon: 1) Saprinus (S.) caerulescens caerulescens (Hoffmann, 1803); 2) S. (S.) calatravensis Fuente, 1899; 3) S. (S.) chalcites (Illiger, 1807); 4) S. (S.) godet (Brullé, 1832); 5) S. (S.) maculatus (P. Rossi, 1792); 6) S. (S.) strigil Marseul, 1855; 7) S. (S.) submarginatus J. Sahlberg, 1913; and 8) S. (S.) tenuistrius sparsutus Solsky, 1876. The peak activity was recorded, key for the species is provided, and habitus images and male genitalia are illustrated in order to facilitate their taxonomic identifications. Saprinus species are diverse and common on animal carcass; they were likewise collected from a human cadaver in Lebanon. Preliminary comments on biology and distribution of the studied species are given. Our paper represents the first faunistic study on Histeridae from Lebanon. A rigorous research program regarding the biology of Saprinus in Lebanon and the neighbouring countries would greatly improve the knowledge of the diversity, activity, and possible forensic value of Saprinus.

RESUMO

The Australopacific Saprininae, containing twelve genera and forty species, are reviewed, illustrated and keyed to genera and species. Two new genera, Australopachylopusgen. n. (New Zealand, type species Saprinus lepidulus Broun, 1881) and Iridoprinusgen. n. (Australia, type species I. myrmecophilussp. n.) and four new species: Saprinus (Saprinus) rarus sp. n. (Australia), Saprinus (Saprinus) chathamensis sp. n. (Chatham Islands, New Zealand), Saprinus (Saprinus) pseudodetritus sp. n. (Chatham Islands, New Zealand) and Saprinus (Saprinus) pacificus sp. n. (Kiribati) are described. The Saprininae fauna of the Australopacific Region is a mixture of northern invaders that most likely arrived to the region in early Cenozoic by 'island hopping' from north (Hypocaccus, Hypocacculus, several Saprinus) and truly autochthonous taxa either with uncertain phylogenetic affinities (Iridoprinusgen. n., Saprinodes Lewis, 1891, Reichardtia Wenzel, 1944, Australopachylopusgen. n.), primitive Australopacific endemics (e.g. Tomogenius Marseul, 1862) or presumed relicts (several species of Saprinus Erichson, 1834). Several Saprininae taxa (Chalcionellus aeneovirens (Schmidt, 1890); (Gnathoncus rotundatus (Kugelann, 1792); G. communis (Marseul, 1862); Euspilotus (Neosaprinus) rubriculus (Marseul, 1855); Hypocaccus (Nessus) interpunctatus interpunctatus (Schmidt, 1885); Saprinus (S.) chalcites (Illiger, 1807) and Saprinus (S.) cupreus Erichson, 1834)) were introduced into the region with human activity. We report the first cases of myrmecophily (Iridoprinus myrmecophilusgen. et sp. n.) and termitophily (Saprinus rarussp. n.) in the Saprininae from the Australopacific Region. Lectotypes and paralectotypes of the following taxa are designated herein: Saprinus amethystinus Lewis, 1900, Saprinus apricarius Erichson, 1834, Saprinus artensis Marseul, 1862, Saprinus auricollis Marseul, 1855, Saprinus australasiae Blackburn, 1903, Saprinus bistrigifrons Marseul, 1855, Saprinus certus Lewis, 1888, Saprinus communis Marseul, 1862, Saprinus cupreus Erichson, 1834, Saprinus cyanellus Marseul, 1855, Hister cyaneus Fabricius, 1775, Saprinus dentipes Marseul, 1855, Saprinus desbordesi Auzat, 1916, Saprinus gayndahensis MacLeay, 1871, Saprinus hyla Marseul, 1864, Saprinus incisisternus Marseul, 1862, Saprinus incisus Erichson, 1842, Saprinus irinus Marseul, 1862, Saprinus laetus Erichson, 1834, Saprinus lepidulus Broun, 1881, Saprinus mastersii MacLeay, 1871, Saprinus nitiduloides Fairmaire, 1883, Saprinus pedator Sharp, 1876, Saprinus pseudocyaneus White, 1846, Saprinus rubriculus Marseul, 1855, Saprinus sinae Marseul, 1862, Saprinus tasmanicus Marseul, 1855, Saprinus tyrrhenus Blackburn, 1903, Saprinus varians Schmidt, 1890, Saprinus vernulus Blackburn, 1903, Saprinus viridanus Lewis, 1899, Saprinus viridipennis Lewis, 1901, and Saprinus westraliensis Blackburn, 1903. The synonymy of Saprinus tyrrhenus Blackburn, 1903 is revoked and the species is considered as valid (stat. n.). Seven new synonymies are proposed: Saprinus gayndahensis MacLeay, 1871 = Saprinus laetus Erichson, 1834 syn. n., Saprinus pseudocyaneus White, 1846 = Saprinus laetus Erichson, 1834 syn. n., Saprinus mastersii MacLeay, 1871 = Saprinus laetus Erichson, 1834 syn. n., Saprinus dentipes Marseul, 1855 = Hypocaccus (Baeckmanniolus) gaudens (J.L. LeConte, 1851) syn. n., Hypocaccus (Hypocaccus) vernulus (Blackburn, 1903) = Hypocaccus (Hypocaccus) sinae (Marseul, 1862) syn. n., Saprinus (Saprinus) lindrothi Dahlgren, 1968 = Saprinus (Saprinus) prasinus Erichson, 1834 syn. n., and Saprinus (Saprinus) certus Lewis, 1888 = Saprinus (Saprinus) frontistrius Marseul, 1855 syn. n. The following new records are: Euspilotus (Neosaprinus) rubriculus (Marseul, 1855) (= Saprinus gnathoncoides Bickhardt, 1909) (Australia), Saprinus (Saprinus) laetus Erichson, 1834 (Lord Howe Island) and Saprinus (Saprinus) cyaneus cyaneus (Fabricius, 1775) (Lord Howe Island and Fiji).

RESUMO

The genus Reichardtiolus Kryzhanovskij, 1959 is revised herein. It now contains five species: R. duriculus (Reitter, 1904) from middle Asia (with a doubtful female specimen from western China that is here tentatively assigned to this species), R. pavlovskii Kryzhanovskij, 1959 from Turkmenistan, R. sphingis (Peyerimhoff, 1936), comb. n. (transferred from Saprinus Erichson, 1834) from Egypt and Jordan, R. perses sp. n. from Iran and R. aldhaferi sp. n. from Saudi Arabia. Except for R. pavlovskii, which is a rather distinct species known only from two females, the remaining species are allopatric, very similar externally and are best separated from each other by their male terminalia. R. pavlovskii is kept in Reichardtiolus only tentatively, pending the examination of more specimens, and especially its male genitalia. R. duriculus and R. pavlovskii are re-described, while R. perses sp. n., R. aldhaferi sp. n. and R. sphingis comb. n. are provided with diagnostic descriptions because of their overall similarity with R. duriculus. Morphological differences of all species are illustrated using SEM micrographs. Male genitalia of R. duriculus, R. sphingis comb. n., R. perses sp. n. and R. aldhaferi sp. n. are illustrated and a key to the species is given. R. duriculus is newly recorded from Tajikistan.

RESUMO

Based on the results of recent phylogenetic analysis of the higher taxa of the Saprininae as well as external morphological characters, especially the presence of deep and large prosternal foveae, and the shape and position of the sensory organs of the antennal club, the species Saprinus (s.str.) caeruleatus Lewis, 1905 is excluded from the genus Saprinus and a new genus Malagasyprinus, exclusive to Madagascar, is established for it. The new genus shows mainly characters that are apomorphic for the subfamily and contains another two, highly similar allopatric species Malagasyprinus perrieri sp. n., and Malagasyprinus diana sp. n., described herein. The three species are best separated from each other by the structure of the prosternum and male terminalia, especially the shape of the aedeagus. We re-describe Malagasyprinus caeruleatus comb. n. and provide Malagasyprinus perrieri and Malagasyprinus diana with brief differential diagnoses. All taxon descriptions are accompanied with color habitat photographs, SEM micrographs and drawings of their male genitalia. A key to the species of Malagasyprinus is given. Sensory structures of the antenna of Malagasyprinus caeruleatus comb. n. are likewise depicted herein. The systematic position of the newly erected genus is discussed. A lectotype of Saprinus caeruleatus Lewis, 1905 is designated.


RésuméSe référant aux résultats des récentes analyses phylogénétiques portant sur les taxa supérieurs des Saprininae ainsi que sur des caractères morphologiques externes comme les larges et profondes fovéoles prosternales et les forme et position des organes sensoriels des massues antennaires, l'espèce Saprinus (s.str.) caeruleatus Lewis, 1905 est exclue du genre Saprinus et un nouveau genre Malagasyprinus, endémique de Madagascar, est établi pour le recevoir. Le nouveau genre présente principalement des caractères apomorphes pour les Saprininae, et contient aussi deux autres espèces allopatriques et similaires Malagasyprinus perrierisp. n. et Malagasyprinus dianasp. n. décrites ici. Les trois espèces sont bien séparées les unes des autres par la structure de leurs prosternums et par leurs genitalia mâles, spécialement la forme des édéages. Nous re-décrivons Malagasyprinus caeruleatuscomb. n. et donnons de courtes diagnoses différentielles de Malagasyprinus perrieri et Malagasyprinus diana. Toutes les descriptions sont accompagnées des photographies d'habitus en couleurs, de photographies au microscope à balayage (MEB) et de dessins des genitalia mâles. Un tableau des espèces de Malagasyprinus est donné. Les structures sensorielles antennaires de Malagasyprinus caeruleatus sont également représentées. La position systématique du nouveau genre est discutée. Le lectotype de Saprinus caeruleatus Lewis, 1905 est désigné.

RESUMO

A new genus and species from Kenya, Afroprinus cavicola is herein described and illustrated and its systematic position is discussed. By the prosternal pre-apical foveae connected by marginal prosternal stria it resembles most of the Afrotropical species of the genus Chalcionellus Reichardt, 1932, or some species of the genus Pholioxenus Reichardt, 1932 from South Africa and Namibia. Afroprinus can be distinguished from Chalcionellus chiefly by the lack of pronotal depressions and a coarsely sculptured, non-metallic dorsum; from Afrotropical species of Pholioxenus it can be most easily distinguished by the asetose pronotal hypomeron. The new taxon was discovered in a cave, but lacks obvious troglophilic adaptations. Notes on other Saprininae taxa found in caves are given. An identification key to the genera of Afrotropical Saprininae is provided.
