The dramatic increase in soil degradation in the last few decades has led to the need to identify methods to define not only soil quality but also, in a holistic approach, soil health. In the past twenty years, indices based on living communities have been proposed alongside the already proven physical-chemical methods. Among them, some soil invertebrates have been included in monitoring programs as bioindicators of soil quality. Being an important portion of soil fauna, soil arthropods are involved in many soil processes such as organic matter decomposition and translocation, nutrient cycling, microflora activity regulation and bioturbation. Many studies have reported the use of soil arthropods to define soil quality; among taxa, some have been explored more in depth, typically Acari and Collembola, while generally less abundant groups, such as Palpigradi or Embioptera, have not been investigated much. This paper aims to evaluate and compare the use of different soil microarthropod taxa in soil degradation/quality studies to highlight which groups are the most reported for soil monitoring and which are the most sensitive to soil degradation. We have decided not to include the two most present and abundant taxa, Acari and Collembola, in this paper in consideration of the vast amount of existing literature and focus the discussion on the other microarthropod groups. We reported some studies for each taxon highlighting the use of the group as soil quality indicator. A brief section reporting some indices based on soil microarthropods is proposed at the end of this specific discussion. This paper can be considered as a reference point in the use of soil arthropods to estimate soil quality and health.

Resumen: Las especies invasoras pueden causar diversos problemas a nivel socioeconómico y para la conservación de la biodiversidad. La detección temprana de las especies naturalizadas puede ser de vital importancia para el monitoreo y la planificación de estrategias de contención del proceso de invasión. La fauna de planarias terrestres (Tricladida, Geoplanoidea), babosas terrestres (Mollusca, Limacidae), diplópodos (Myriapoda, Diplopoda) y sínfilos (Myriapoda, Symphylla) de la Ciudad Autónoma de Buenos Aires se encuentra poco estudiada, y la adición de especies exóticas transportadas por las actividades humanas complejiza la situación de poco conocimiento. En este trabajo se dan a conocer nuevos registros de especies de estos grupos que se han naturalizado en el ámbito urbano de la ciudad y sus alrededores (Bipalium kewense, Austroplana sanguinea, Ambigolimax valentianus, Brachyiulus pusillus, Oxidus gracilis y Scutigerella immaculata). Se evaluó el potencial como invasor de cada especie en base a lo registrado en otros países. Hasta el día de la fecha no existen registros publicados de planarias terrestres, sínfilos, o diplópodos para esta área, por lo cual el presente trabajo constituye la primera contribución sobre estos grupos. Las especies mencionadas perjudican a las actividades agropecuarias y horticulturales de diversas formas. Una tarea a futuro deberá ser la cuantificación de los daños que causan para establecer su importancia y el costo/beneficio de su control o manejo.

New or poorly known exotic invertebrates from Buenos Aires City

Abstract: Exotic invertebrates in the city of Buenos Aires. First steps for the monitoring of potential biological invasions. Invasive species can cause several problems at the socio-economic level and for the biodiversity conservation. The early detection of naturalized species can be of vital importance for the planning of containment strategies of the invasion process. The flat worms (Tricladida, Geoplanoidea), land slugs (Mollusca, Limacidae), millipedes (Myriapoda, Diplopoda) and symphillids (Myriapoda, Symphyla) of the Ciudad Autónoma de Buenos Aires it is little studied, and the addition of exotic species transported by human activities complicates the situation of little knowledge. In this work, we present new records of species of these groups that have become naturalized in the urban area of the city and its surroundings (Bipalium kewense, Austroplana sanguinea, Ambigolimax valentianus, Brachyiulus pusillus, Oxidus gracilis y Scutigerella immaculata). The invasive potential of each species was evaluated based on what was registered in other countries. Until the date there are no published records of terrestrial flat worms, symphillids, or millipedes for this area, for which the present work constitutes the first contribution on these groups. The aforementioned species damage agricultural and horticultural activities in different ways. A future task should be the quantification of the damage caused to establish its importance and the cost / benefit of its control or management.

Abstract: Forest clearance, especially in the tropics, leads to habitat loss for many organisms including litter-dwelling arthropods. Among other invertebrates, millipedes (Diplopoda) provide important ecosystem services like decomposition and nutrient cycling in forest ecosystems. Despite their importance, little is known about litter inverte-brates' response to tropical forest degradation and their role in reforestation. The present article should rather be regarded as a review of millipedes' occurrence in tropical forests with a pilot study from Madagascar, because the sample size is small and results need to be confirmed. This pilot study investigated the relationship between millipedes and vegetation characteristics in the eastern rainforests of Madagascar, in the region of Andasibe, parts of which are undergoing reforestation.

Vegetation characteristics were measured in ten different forests encompassing different types: remnant rainforest, secondary forest, old Eucalyptus plantations, recently enriched with indigenous tree species, and degraded sites. Millipede species were searched by hand, identified and their occurrence in relation to the environmental characteristics was described. Vegetation characteristics differed between forest types. Old Eucalyptus plantations, secondary forest, and primary rainforest were associated with higher litter depth and more native millipede species than degraded sites and forests afforested with native tree species since 2007. Non-native millipedes occurred in all vegetation formations except the primary rainforest site and did not show any relationship with vegetation characteristics. In contrast, native milli-pedes' occurrence was related to conditions associated with mature forest, such as high litter depth and high foliage cover. Logistic regression revealed a threshold of litter depth above which native millipedes are likely to occur. The results indicate that native milli-pedes are affected by forest degradation and are incompletely restored even when the afforested forest might approach the original state. Special care should be taken during reforestation efforts, as non-native soil arthropods can be introduced, completely replacing the indigenous biota.

Resumé: Les conséquences de la déforestation globale sont multiples. Pour la plupart des organismes, la déforestation est la cause principale de la destruction des habitats. Les arthropodes qui vivent sur le sol forestier ou dans le feuillage sont ainsi menacés, surtout dans les forêts tropicales. Ces organismes sont pourtant indispensables au maintien de la résilience de la forêt. Dans l’écosystème forestier, les millepattes et autres arthropodes sont très importants pour la mise à disposition de différents services écosystémiques, par exemple pour leur rôle dans le cycle des éléments nutritifs, la formation des sols et la décomposition. Malgré leur importance, peu d’informations sont disponibles sur la réaction des invertébrés suite à la dégradation des forêts et leur rôle dans la reforestation.

Cette étude tient surtout lieu de révision de l’occurrence des millepattes dans les forêts tropicales avec une étude pilote menée à Madagascar, dans la mesure où l'échantillonnage est réduit et que les résultats restent partiels. Cette étude pilote analyse les relations entre les millepattes et les caractéristiques végétales dans les forêts de l’Est de Madagascar, dans la région d’Andasibe. Ces forêts sont très diverses et dix types de forêt ont été considérés, à savoir une forêt récemment dégradée et une forêt dégradée, une forêt dégradée et reboisée avec des espèces arborées indigènes en 2007, 2012 ou 2015, des plantations d’Eucalyptus abandonnées depuis 1930 ou 1909, deux forêts secondaires, une forêt primaire. Dans ces différents types de forêt, les caractéristiques de la végétation ont été enregistrées et des millepattes ont été récoltés à la main. Les espèces de millepattes ont été identifiées et leur occurrence ont été analysées par rapport aux caractéristiques de la végétation. Les vieilles plantations d’Eucalyptus et les forêts secondaire et primaire étaient caractérisées par une couche plus épaisse de feuilles et davantage d’espèces de millepattes indigènes par rapport aux forêts dégradée et replantée. Les espèces allogènes étaient présentes dans tous les types de forêt à l’exception de la forêt primaire. La présence de ces espèces n’était pas liée aux caractéristiques de la végétation. En revanche, l’occurrence des espèces indigènes était associée à des conditions qui sont caractéristiques des forêts matures, par exemple une couche de feuilles épaisse et une couverture foliaire dense. L’analyse de régression logistique a révélé une valeur seuil pour la hauteur de la couche de feuilles mortes. Au-delà de ce seuil, il est probable que les millepattes indigènes soient présents. L’étude a montré que les millepattes indigènes sont impactés par la déforestation et qu’ils ne sont pas facilement restaurés même si la restauration semble permettre à la forêt de se rapprocher de son état initial.

The Myriapoda, composed of millipedes and centipedes, is a fascinating but poorly understood branch of life, including species with a highly unusual body plan and a range of unique adaptations to their environment. Here, we sequenced and assembled 2 chromosomal-level genomes of the millipedes Helicorthomorpha holstii (assembly size = 182 Mb; shortest scaffold/contig length needed to cover 50% of the genome [N50] = 18.11 Mb mainly on 8 pseudomolecules) and Trigoniulus corallinus (assembly size = 449 Mb, N50 = 26.78 Mb mainly on 17 pseudomolecules). Unique genomic features, patterns of gene regulation, and defence systems in millipedes, not observed in other arthropods, are revealed. Both repeat content and intron size are major contributors to the observed differences in millipede genome size. Tight Hox and the first loose ecdysozoan ParaHox homeobox clusters are identified, and a myriapod-specific genomic rearrangement including Hox3 is also observed. The Argonaute (AGO) proteins for loading small RNAs are duplicated in both millipedes, but unlike in insects, an AGO duplicate has become a pseudogene. Evidence of post-transcriptional modification in small RNAs—including species-specific microRNA arm switching—providing differential gene regulation is also obtained. Millipedes possesses a unique ozadene defensive gland unlike the venomous forcipules found in centipedes. We identify sets of genes associated with the ozadene that play roles in chemical defence as well as antimicrobial activity. Macro-synteny analyses revealed highly conserved genomic blocks between the 2 millipedes and deuterostomes. Collectively, our analyses of millipede genomes reveal that a series of unique adaptations have occurred in this major lineage of arthropod diversity. The 2 high-quality millipede genomes provided here shed new light on the conserved and lineage-specific features of millipedes and centipedes. These findings demonstrate the importance of the consideration of both centipede and millipede genomes—and in particular the reconstruction of the myriapod ancestral situation—for future research to improve understanding of arthropod evolution, and animal evolutionary genomics more widely.

The year 2018 is particularly important in the history of zoological research in Poland. A hundred years ago, Kazimierz Demel published the first work concerning the terrestrial cave fauna of caves in the Ojców area. In this paper we present the extent of research on the terrestrial invertebrate fauna of Polish caves in the last 100 years. All accessible research papers that have been published during this period were analysed. Based on published literature, 593 species of terrestrial invertebrate were recorded in Polish caves. Additionally, detailed list of species of individual taxonomic groups was provided.

Urbanisation is increasing worldwide and is regarded a major driver of environmental change altering local species assemblages. Private domestic gardens contribute a significant share of total green area in cities, but their biodiversity has received relatively little attention. Previous studies mainly considered plants, flying invertebrates such as bees and butterflies, and birds. By using a multi-taxa approach focused on less mobile, ground-dwelling invertebrates, we examined the influence of local garden characteristics and landscape characteristics on species richness and abundance of gastropods, spiders, millipedes, woodlice, ants, ground beetles and rove beetles. We assume that most of the species of these groups are able to complete their entire life cycle within a single garden. We conducted field surveys in thirty-five domestic gardens along a rural-urban gradient in Basel, Switzerland. Considered together, the gardens examined harboured an impressive species richness, with a mean share of species of the corresponding groups known for Switzerland of 13.9%, ranging from 4.7% in ground beetles to 23.3% in woodlice. The overall high biodiversity is a result of complementary contributions of gardens harbouring distinct species assemblages. Indeed, at the garden level, species richness of different taxonomical groups were typically not inter-correlated. The exception was ant species richness, which was correlated with those of gastropods and spiders. Generalised linear models revealed that distance to the city centre is an important driver of species richness, abundance and composition of several groups, resulting in an altered species composition in gardens in the centre of the city. Local garden characteristics were important drivers of gastropod and ant species richness, and the abundance of spiders, millipedes and rove beetles. Our study shows that domestic gardens make a valuable contribution to regional biodiversity. Thus, domestic urban gardens constitute an important part of green infrastructure, which should be considered by urban planners.

Summary: The millipede Oxidus gracilis (C. L. Koch, 1847) is a cosmopolitan introduced species largely recorded in the southeast region of Brazil. The species is considered an agricultural pest with records in poly- or monocultures, and its influence on native communities of plants and invertebrates is still unknown in Brazil. From this perspective, a maximum entropy model was used to explore the predicted distribution of O. gracilis in Brazil. The results showed a highly suitable area in Atlantic Forest (AUC = 0.949 ± 0.02). Considering percent contribution, annual mean temperature (= 54.9) was the main variable which has influenced the modeling. The potentially suitable areas recovered in Atlantic Forest suggest that attention should be given to its possible invasion and the potential damage of O. gracilis to natural communities.

Modélisation de la niche écologique prédisant l’invasion potentielle du mille-pattes non indigène Oxidus gracilis (C. L. Koch, 1847) (Polydesmida : Paradoxosomatidae) dans la forêt atlantique brésilienne

Résumé: Le mille-pattes Oxidus gracilis (C. L. Koch, 1847) est une espèce introduite cosmopolite et largement observée dans la région sud-est du Brésil. L’espèce est considérée comme un ravageur agricole des mono- et polycultures, et son influence sur les communautés indigènes de plantes et d’invertébrés est encore inconnue au Brésil. Dans cette perspective, un modèle d’entropie maximale a été utilisé pour explorer la distribution potentielle d’O. gracilis au Brésil. Les résultats ont montré une zone favorable élevée dans la forêt atlantique (AUC = 0.949 ± 0.02). La température moyenne annuelle (= 54.9) a été la principale variable qui a influencé la modélisation. Les zones potentiellement favorables de la forêt atlantique suggèrent qu’il faut être vigilant quant à sa possible invasion et aux dommages potentiels sur les communautés indigènes.

The P450 family (CYP genes) of arthropods encodes diverse enzymes involved in the metabolism of foreign compounds and in essential endocrine or ecophysiological functions. The P450 sequences (CYPome) from 40 arthropod species were manually curated, including 31 complete CYPomes, and a maximum likelihood phylogeny of nearly 3000 sequences is presented. Arthropod CYPomes are assembled from members of six CYP clans of variable size, the CYP2, CYP3, CYP4 and mitochondrial clans, as well as the CYP20 and CYP16 clans that are not found in Neoptera. CYPome sizes vary from two dozen genes in some parasitic species to over 200 in species as diverse as collembolans or ticks. CYPomes are comprised of few CYP families with many genes and many CYP families with few genes, and this distribution is the result of dynamic birth and death processes. Lineage-specific expansions or blooms are found throughout the phylogeny and often result in genomic clusters that appear to form a reservoir of catalytic diversity maintained as heritable units. Among the many P450s with physiological functions, six CYP families are involved in ecdysteroid metabolism. However, five so-called Halloween genes are not universally represented and do not constitute the unique pathway of ecdysteroid biosynthesis. The diversity of arthropod CYPomes has only partially been uncovered to date and many P450s with physiological functions regulating the synthesis and degradation of endogenous signal molecules (including ecdysteroids) and semiochemicals (including pheromones and defense chemicals) remain to be discovered. Sequence diversity of arthropod P450s is extreme, and P450 sequences lacking the universally conserved Cys ligand to the heme have evolved several times. A better understanding of P450 evolution is needed to discern the relative contributions of stochastic processes and adaptive processes in shaping the size and diversity of CYPomes.
