Abstract (sommario):

The status of Myriapoda (whether mono-, para- or polyphyletic) and position of myriapods in the Arthropoda are controversial, an impediment to evaluating fossils that may be members of the myriapod stem-group. Parsimony analysis of 319 characters for extant arthropods provides a basis for defending myriapod monophyly and identifying those morphological characters that are necessary to assign a fossil taxon to the Myriapoda. The alliance of hexapods and crustaceans need not relegate myriapods to the arthropod stem-group; the Mandibulata hypothesis accommodates Myriapoda and Tetraconata as sister taxa. No known pre-Silurian fossils have characters that convincingly place them in the Myriapoda or the myriapod stem-group. Because the strongest apomorphies of Myriapoda are details of the mandible and tentorial endoskeleton, exceptional fossil preservation seems necessary to recognise a stem-group myriapod.

Abstract (sommario):

Identifying marine or freshwater fossils that belong to the stem groups of the major terrestrial arthropod radiations is a longstanding challenge. Molecular dating and fossils of their pancrustacean sister group predict that myriapods originated in the Cambrian, much earlier than their oldest known fossils, but uncertainty about stem group Myriapoda confounds efforts to resolve the timing of the group’s terrestrialization. Among a small set of candidates for membership in the stem group of Myriapoda, the Cambrian to Triassic euthycarcinoids have repeatedly been singled out. The only known Devonian euthycarcinoid, Heterocrania rhyniensis from the Rhynie and Windyfield cherts hot spring complex in Scotland, reveals details of head structures that constrain the evolutionary position of euthycarcinoids. The head capsule houses an anterior cuticular tentorium, a feature uniquely shared by myriapods and hexapods. Confocal microscopy recovers myriapod-like characters of the preoral chamber, such as a prominent hypopharynx supported by tentorial bars and superlinguae between the mandibles and hypopharynx, reinforcing an alliance between euthycarcinoids and myriapods recovered in recent phylogenetic analysis. The Cambrian occurrence of the earliest euthycarcinoids supplies the oldest compelling evidence for an aquatic stem group for either Myriapoda or Hexapoda, previously a lacuna in the body fossil record of these otherwise terrestrial lineages until the Silurian and Devonian, respectively. The trace fossil record of euthycarcinoids in the Cambrian and Ordovician reveals amphibious locomotion in tidal environments and fills a gap between molecular estimates for myriapod origins in the Cambrian and a post-Ordovician crown group fossil record.

Abstract (sommario):

Red Listing of Threatened species is recognized as the most objective approach for evaluating extinction risk of living organisms which can be applied at global or national scales. Invertebrates account for nearly 97% of all animals on the planet but are insufficiently represented in the IUCN Red Lists at both scales. To analyze the occurrence of species present in regional Red Lists, accounts of 48 different countries and regions all over the world were consulted and all data about myriapods (Myriapoda) ever assessed in Red Lists at any level assembled. Myriapod species assessments were found in eleven regional Red Lists; however, no overlap between the species included in the global IUCN Red List and the regional ones was established. This means that myriapod species considered threatened at regional level may not be eligible for international funding specific for protection of native threatened species (more than US$ 25 million were available in the last decade) as most financial instruments tend to support only threatened species included in the IUCN Red List. As the lack of financial resources may limit protection for species in risk of extinction, it is urgent to increase the possibilities of getting financial support for implementation of measures for their protection. A Red List of all Myriapoda species recorded in Red Lists at national or local (596) and global (210) scales totaling 806 species is presented. This list shows for the first time an overview of the current conservation status of Myriapoda species. Here, the urgent need of establishing a Myriapoda Specialist Group in the Species Survival Commission of IUCN is also stressed.

Abstract (sommario):

Understanding animal terrestrialization, the process through which animals colonized the land, is crucial to clarify extant biodiversity and biological adaptation. Arthropoda (insects, spiders, centipedes and their allies) represent the largest majority of terrestrial biodiversity. Here we implemented a molecular palaeobiological approach, merging molecular and fossil evidence, to elucidate the deepest history of the terrestrial arthropods. We focused on the three independent, Palaeozoic arthropod terrestrialization events (those of Myriapoda, Hexapoda and Arachnida) and showed that a marine route to the colonization of land is the most likely scenario. Molecular clock analyses confirmed an origin for the three terrestrial lineages bracketed between the Cambrian and the Silurian. While molecular divergence times for Arachnida are consistent with the fossil record, Myriapoda are inferred to have colonized land earlier, substantially predating trace or body fossil evidence. An estimated origin of myriapods by the Early Cambrian precedes the appearance of embryophytes and perhaps even terrestrial fungi, raising the possibility that terrestrialization had independent origins in crown-group myriapod lineages, consistent with morphological arguments for convergence in tracheal systems. This article is part of the themed issue ‘Dating species divergences using rocks and clocks’.

Abstract (sommario):

ABSTRACTSeveral specimens of myriapodous arthropods have been discovered at the early Carboniferous East Kirkton site near Bathgate, West Lothian, Scotland. None is particularly well preserved, but they are the earliest known Carboniferous myriapods, filling the time gap between the Old Red Sandstone of the early Devonian and the abundant myriapod faunas of the late Carboniferous (Pennsylvanian). One of the specimens, a milliped, provides the earliest evidence for both ozopores (repugnatorial gland openings) and spiracles. A second milliped specimen has some characteristics of the living Order Glomeridesmida, and hence of Enghoff's (1990) ‘ground plan’ of chilognathan millipeds. Aspects of these forms and a third suggest a novel early Carboniferous fauna clearly different from both earlier and later ones. The taxon name ‘Myriapoda’ should be abandoned, since it covers a group now recognised as paraphyletic. ‘Archipolypoda’ is probably synonymous with Order Euphoberiida, Class Diplopoda.

Abstract (sommario):

Objective: To determine the leaf litter myriapod community in two restoration strategies of a protective area of Colombia, a secondary forest and an Andean alder plantation. Scope: The knowledge of the biodiversity of invertebrates associated with leaf litter breakdown in restoration forests may contribute to assessing the restoration process efficiency and success. Within this forested soil biodiversity framework, myriapods influence organic matter dynamics by transforming leaf litter (or other plant-derived materials), reducing the surface of decomposition, and affecting decomposer communities and their interactions. Methodology: We designed a leaf litter translocation experiment using leaf litter of Alnus acuminata Kunth and Hedyosmum bonplandianum Kunth, the most abundant species in each restoration strategy underway from the 60s in the Reserva Natural Río Blancoy Quebrada Olivares, Manizales, Colombia. We measured the myriapod richness and abundance two and four months after beginning the leaf litter decomposition experimental trials. Main results: Classes Diplododa, Chilopoda, and Symphyla colonized the leaf litter in both restoration strategies. The restoration strategy affected myriapod richness, abundance and composition. Myriapod richness and abundance were greater in the Andean alder plantation, millipedes were the most abundance myriapods. Myriapod composition also differs among litter species. The plant composition of each restoration strategy could lead to differences in litterfall quality and, consequently, in the resources available for the colonization of the myriapod community, which contributes directly and indirectly to the decomposition process in the restoration strategies.

Abstract (sommario):

The biodiversity crisis we live in, marked by high extinction rates, requires well-planned conservation efforts. To overcome this issue, red lists of threatened species are recognized as the main objective approach for evaluating the conservation status of species and therefore guiding conservation priorities. This work focuses on the Myriapoda (Chilopoda and Diplopoda) species listed in the Brazilian red list of fauna to enable discussion of the practical implications of red lists for conservation. Almost all myriapods assessed are endemic to Brazil (99 %) and 73 % are known from subterranean habitats only. Despite of 33 % being recorded from protected areas (PAs), downgrading, degazettement or downsizing of PAs and intense and unregulated ecotourism represent great threats. The PAs network in Brazil tends to fail in conserving myriapod species. The number of data deficient species (42 %) states the need of investing in ecological and taxonomic studies about the group, in order to fill in important knowledge gaps in species assessments nationally and globally. In this work we show that there is a lack of communication between national and global agencies concerning red lists, which results in a significant loss for science and for conservation. Despite investing in national and state red lists, individual countries must take the final step of submitting its data to IUCN global database, as significant international funding is available for IUCN red listed species conservation. Being one of the most diverse countries in the world, and facing the biggest cuts ever on national science funding, losing these important funding opportunities is a huge loss for Brazilian biodiversity conservation and for science. This study raises awareness on subterranean habitats conservation, due to its high endemism and fragility. Since the first edition of the Brazilian Red List in 1968, centipedes are now included for the first time, and millipedes for the second time. The presence of these myriapods in the list brings attention to the group, which usually receives little or no attention in conservation programs and environmental impact assessments. Rather than a specific case for Myriapoda and for Brazil, the points discussed here can be related to arthropods and the tropics, as the most biodiverse countries are emerging economies facing similar challenges in PAs network management, species extinction risks and science funding.

Abstract (sommario):

The currently documented fauna of described species of myriapods in Canada includes 54 Chilopoda, 66 Diplopoda, 23 Pauropoda, and two Symphyla, representing increases of 24, 23, 23, and one species, respectively, since 1979. Of the 145 myriapod species currently documented, 40 species are not native to Canada. The myriapods have not been well documented with DNA barcodes and no barcodes are available for Pauropoda. It is conservatively estimated that at least 93 additional myriapods species will be discovered in Canada: Chilopoda (40), Diplopoda (29), Pauropoda (17), and Symphyla (seven). In general, there is a serious dearth of knowledge about myriapods in Canada, and systematics research and surveys continue to be needed to help document the diversity and distribution of these groups in the country.

Abstract (sommario):

Background There have been extensive debates on the interrelationships among the four major classes of Myriapoda—Chilopoda, Symphyla, Diplopoda, and Pauropoda. The core controversy is the position of Pauropoda; that is, whether it should be grouped with Symphyla or Diplopoda as a sister group. Two recent phylogenomic studies separately investigated transcriptomic data from 14 and 29 Myriapoda species covering all four groups along with outgroups, and proposed two different topologies of phylogenetic relationships. Methods Building on these studies, we extended the taxon sampling by investigating 39 myriapods and integrating the previously available data with three new transcriptomic datasets generated in this study. Our analyses present the phylogenetic relationships among the four major classes of Myriapoda with a more abundant taxon sampling and provide a new perspective to investigate the above-mentioned question, where visual genes’ identification were conducted. We compared the appearance pattern of genes, grouping them according to their classes and the visual pathways involved. Positive selection was detected for all identified visual genes between every pair of 39 myriapods, and 14 genes showed positive selection among 27 pairs. Results From the results of phylogenomic analyses, we propose that Symphyla is a sister group of Pauropoda. This stance has also received strong support from tree inference and topology tests.

Abstract (sommario):

La terrestrialisation (colonisation des milieux terrestres) est une étape majeure de l'histoire de la vie. Elle s’accompagne d’une explosion de la diversité biologique en milieu continental (terre ferme, milieu aérien), et remodèle les enveloppes superficielles de la Terre. Dans le règne animal, les arthropodes apparaissent comme les principaux acteurs de cette révolution écologique (ex : insectes, arachnides) qui débute probablement dès l’Ordovicien (485-444 Ma) et s’accentue au Carbonifère (359-299 Ma). Une autre composante majeure de cette faune arthropodienne, les myriapodes (‘milles pattes’), semble avoir colonisé les milieux terrestres très tôt et joué un rôle crucial dans le développement initial des sols et le cycle des nutriments, ouvrant ainsi la voie à de nouvelles colonisations végétales et animales. Le gisement à préservation exceptionnelle de Montceau-les-Mines (Saône-et-Loire ; Carbonifère, ~305 Ma) possède une flore et une faune riches et diversifiées conservées en 3D dans des nodules et offre donc une véritable fenêtre évolutive sur la terrestrialisation. Le but de cette thèse est d'étudier les trois groupes de myriapodes présent à Montceau-les-Mines: les diplopodes ("millipedes" en anglais), les arthropleurides et les euthycarcinoïdes afin de reconstituer avec précision leur morphologie, leur mode de vie, leurs adaptations à la vie continentale, leur rôle dans l’écosystème continental ainsi que leurs relations phylogénétiques (avec leurs représentants actuels)
Terrestrialisation (colonisation of terrestrial environments) is a major step in the history of life. It goes along an explosion of biological diversity in continental environment (land and aerial environment), and reshape the superficial envelopes of Earth. In the animal kingdom, arthropods are one of the main actors of this ecological revolution (ex : insects, arachnids) that begins surely since the Ordovician (485-444 Ma) and increases during the Carboniferous (359-299 Ma). Another main part of this arthropod fauna, the myriapods (millipedes and centipedes), seems to colonise land early and play a crucial role in initial development of soils and nutriments cycle, leading the way to new floral and faunal colonisations. The exceptionnally preserved locality of Montceau-les-Mines (Saône-et-Loire; Carboniferous ~ 305 Ma) yields a rich and diversified flora and fauna preserved in 3D in nodules and offer an evolutive window on terrestriaisation. This PhD goal is to study the three groups of myriapods present in Montceau-les-Mines: the diplopods ("millipedes"), the arthropleurids and the euthycarcinoids to reconstruct with accuracy their morphology, their life mode, their adaptations to continental life, their role in continental ecosystem as well as their phylogenetic relationships (with extant representatives)

Abstract (sommario):

Nous avons examine en languedoc les variations saisonnieres de la structure des peuplements des diplopodes en fonction des perturbations anthropiques, estime leur role de consommateurs de litiere, et teste en laboratoire l'influence de certains facteurs pouvant affecter leur microdistribution ou leur rythme d'activite. Les milieux les plus favorables sont constitues par les taillis, ou les diplopodes forment les peuplements dominants des organismes consommateurs de litiere. Leur role est determinant dans la fragmentation de la litiere, participant a sa transformation en synergie avec les microorganismes edaphiques. La photoperiode, la temperature, l'humidite de la litiere et du substrat, la nature de celui-ci, sont parmi les principaux facteurs qui controlent le taux de consommation de la litiere qui est maximal au printemps et en automne, le froid hivernal et la secheresse estivale ralentissant le processus. La litiere agee est plus consommee que celle de l'annee. L'origine geographique des individus peut modifier les preferences alimentaires. Sous taillis de chene vert les diplopodes fragmentent entre 11 et 15% au moins de la litiere tombee au sol annuellement. De nombreux facteurs anthropiques (coupes a blanc, eclaircies, paturage, pietinement) sont susceptibles de modifier l'organisation des peuplements de diplopodes, entrainant des changements dans le taux de fragmentation de la litiere. Les glomerida sont plus sensibles que les iulida a ces perturbations
The seasonal variation of diplopod community structure has been examined in languedoc, according to anthropic perturbations. The role of the diplopods as litter consumers has been estimated and the influence of specific factors which affect their microdistribution or their activity rythm has been tested in the laboratory. The most favourable environments are constituted by the coppice where the diplopods compose the dominant community among litter consumers. Diplopods have an essential role in the litter fragmentation. They take part in its transformation, synergistically with edaphic microorganisms. Photoperiod, temperature, water content of both leaves and substrate, as well as soil nature, are important factors which control litter consuming rate. This is maximal during spring and autumn because winter frost and summer drought slow down the consuming process. Old litter is more consumed than the current-year litter. The geographic origin of the millipedes can modify feeding preferences. It has been shown that under holm-oak coppice, diplopods fragment at least from 11% to 15% of the litter which falls down annually on the ground. Many anthropic factors (cutting, clearing up, animal feeding, trampling,. . . ) are able to modify the community organization of the diplopods, leading to change in the fragmentation rate of the litter. The glomerida are more sensitive than the iulida to those perturbations

Os artrópodos constituem um grupo que possui um extenso registro fossilífero e hoje constitui o grupo mais abundante e diverso dos animais terrestres. Suas pistas fossilizadas, aliadas a estudos geológicos, fornecem dados importantes para estudos paleoecológicos. Através da análise da oscilação da densidade de icnofósseis ao longo dos horizontes do Parque do Varvito (Município de Itu – SP) foram realizadas inferências sobre a história geológica da área, sobre a população de artrópodos que provavelmente ali viveu e sobre as condições ambientais que a circundava. Para isso foram utilizadas metodologias como a do esquadrinhamento para obter informações a respeito da densidade e direcionamento das pistas e experimentos com a finalidade de reproduzir as pistas em condições semelhantes aquelas encontrados no parque. Além disso, foi realizada uma classificação icnotaxonômica das pistas e sua atribuição a diplópodos (Myriapoda) terrestres. A contextualização da análise tafonômica com a história deposicional do Parque do Varvito levou a conclusão de que os miriápodos, de hábitos terrestres, habitavam uma área de inundações cíclicas e, conseqüentemente, passavam por condições de estresse ambiental no verão, quando a área recebia o afluxo da água de degelo de uma geleira localizada a uma distância relativamente grande da região do Parque durante o Carbonífero. A condição de estresse ambiental para esta fauna, que poderia ou não causar episódios de mortalidade, ocorria em função de uma fina lâmina d’água que provinha da geleira. Pelo fato das pistas estarem com direcionamento preferencial, pode-se inferir que esses animais fugiam das inundações durante o verão (condição estressante), cujo fluxo de água teria provavelmente uma orientação similar. Considerando as evidências da influência periglacial e o aporte da água de degelo, o frio intenso poderia ter levado ao congelamento dos solos no ambiente terrestre, gerando ambientes subaquáticos rasos, bem como a formação de capas de gelo, o que dificultaria as trocas gasosas e a obtenção de nutrientes. As pistas também apresentam formas circulares e semicirculares que foram interpretadas como marcas de agonia do animal sob situação de estresse, corroborando a reconstrução paleoecológica inferida no presente estudo.
The arthropods represent the most extensive fossil register and the most abundant and diverse group of all terrestrial animals. Their track and trails provide important data for the study of this group evolution besides helping understanding their diversity and modern distribution. By analyzing the oscillation of the density of ichnofossils along the horizons of Varvito´s Park (Itu – SP), were made inferences about the geological history of the area, the population of arthropods that probably lived there and on the environmental conditions that surrounded them. For the analysis of the density and direction of the tracks, the methodology used was the esquadrinhamento. Also, an experiment was conducted in order to replicate the tracks in similar conditions to those found in the Park during the Carboniferous. It was made a taxonomic classification of the tracks and they were assigned to terrestrial diplopods (Myriapoda). The contextualization of the taphonomic analysis and the depositional history of Varvito´s Park led to the conclusion that myriapods, which have terrestrial habits, inhabited an area of cyclic flooding and therefore experienced environmental stress conditions in the summer, when the area received an influx of meltwater from a glacier located at a relatively long distance of the Park during the Carboniferous. The condition of environmental stress for this fauna, which may or may not cause episodes of mortality, was taking place due to the a thin sheet of water that came from the glacier. Because the tracks were in a preferred direction, one can infer that these animals got away from floods during the summer (stressful condition), which flow of water would probably have a reverse orientation. Considering the evidences of periglacial influence and the outflow of meltwater, the cold might have led to the freezing of soils in the terrestrial environment, creating shallow underwater environments, as well as the formation of ice sheets, thereby impeding gas exchange and the obtainment of nutrients. The tracks also present circular and semi-circular forms and have been interpreted as marks of animals’ agony under stressed conditions, corroborating the paleoecological reconstruction inferred.

Abstract (sommario):

This chapter discusses the subphylum Myriapoda in correlation with phylum Arthropoda. It enumerates the classes of the arthropod subphylum Myriapoda: Chilopoda (centipedes), Diplopoda (millipedes), Pauropoda (pauropods), and Symphyla (symphylans). Myriapods differ from hexapods and most crustaceans in their retention of a largely homonomous trunk with paired segmental appendages. The chapter shows that Millipedes are slow-moving detritus feeders that generally spend their time burrowing through soil and litter. In contrast, most centipedes are fast-running predators, with one pair of legs per segment and poison claws. The chapter mentions how future research should include centipede venoms, millipede defensive secretions and the genomic and physiological adaptations they acquired in adapting to terrestrial environments.
