Abstract:
Pencemaran tanah yang diakibatkan oleh penambangan minyak bumi berpengaruh terhadap lingkungan, vegetasi, dan kelimpahan arthropoda. Oleh karena itu, perlu dilakukan penelitian dampak pencemaran minyak bumi di tanah terhadap komunitas Arthropoda. Penelitian dilakukan untuk mengetahui perbedaan struktur komunitas arhtropoda tanah di sekitar lokasi eksplorasi minyak bumi. Kelembapan, pH, suhu tanah, dan kadar TPH tanah diukur dan dianalisis untuk mengetahui pengaruhnya terhadap indeks keanekaragaman, dominansi, dan kemerataan arthropoda. Penelitian dilakukan di sumur minyak bumi Desa Mangunjaya Kecamatan Babat Toman pada tanggal 19-24 Februari 2015. Arthropoda dikoleksi menggunakan pit fall traps dan corong barlese-tullgren, pengambilan sampel dilakukan di 96 titik. Identifikasi arthropoda dilakukan di Laboratorium Entomologi Jurusan Hama Penyakit Tanaman Fakultas Pertanian. Analisis kadar TPH tanah menggunakan metode Gravimetri dilakukan di Laboratorium Kimia Fakultas MIPA Universitas Sriwijaya. Hasil penelitian menunjukkan rata-rata TPH dan pH tanah di lokasi eksplorasi minyak bumi yang dilakukan oleh Pertamina EP Asset 1 Field Ramba lebih rendah daripada eksplorasi oleh masyarakat. Kelembaban dan suhu tanah di lokasi eksplorasi oleh Pertamina EP Asset 1 Field Ramba lebih tinggi daripada di lokasi eksplorasi masyarakat. Kadar TPH, pH, kelembaban, dan suhu tanah tidak berpengaruh terhadap indeks keanekaragaman, dominansi, dan kemerataan arhtropoda. Rata-rata indeks keanekaragaman arthropoda tergolong rendah dengan nilai indeks kurang dari 1. Soil contamination caused by the extraction of petroleum affects the environment, vegetation, and abundance of arthropods. Therefore, it is necessary to study the impact of oil pollution on the ground against arthropod community. The research has conducted to determine the differences of terrestrial arthropod around petroleum exploration. Moisture, pH, temperature, and soil TPH (Total Petroleum Hydrocarbon) levels were measured and analyzed to determine its effect on the diversity index, dominance, and evenness of arthropods. The research has been done in the petroleum wells in Mangunjaya village of Babat Toman Toman districts on February 19 to 24, 2015. Arthropods samples were taken using pit fall traps and funnel barlese-tullgren, total sampling points are 96 points. Identification of the arthropod family has been done in Entomology Laboratory of the Agriculture Plant Disease Faculty Sriwijaya University. Analysis of soil TPH levels are using Gravimetry methods carried out in the Chemistry Laboratory of Science Faculty, Sriwijaya University. The results showed an average TPH and pH of soil in petroleum exploration conducted by Pertamina EP 1 Field Asset Ramba lower than in locations that made exploration by the public. Moisture and soil temperature at the location of the exploration by Pertamina EP 1 Field Asset Ramba are higher than in public exploration location. TPH levels, pH, moisture, and soil temperature do not affect the diversity, dominance, and evenness arhtropod index. However, the average index of arthropod diversity is low with an index value of less than 1.

Abstract:
Abstrak. Arthropoda merupakan filum yang paling dominan di antara filum hewan lainnya jika ditinjau dari keanekaragaman, penyebaran, dan jumlah spesiesnya. Pada pertanaman kopi arabika terdapat arthropoda yang berperan sebagai herbivor, musuh alami, serangga penyerbuk, serangga netral, dan dekomposer. Secara umum, tindakan pengelolaan yang dilakukan oleh petani pada pertanaman kopi di Desa Atang Jungket Kabupaten Aceh Tengah adalah dengan menggunakan pestisida sintetik tanpa mempedulikan kondisi agroekosistemnya. Supaya agroekosistem kopi tetap stabil dan berkelanjutan, maka perlu dilakukan tindakan pengelolaan yang ramah lingkungan yaitu dengan menggunakan perangkap warna dimana proses penemuan inang serangga didasari oleh faktor visual yang bertujuan untuk mengetahui warna perangkap yang disukai oleh arthropoda pada areal pertanaman kopi arabika. Pada penelitian ini digunakan metode purposive sampling (ditetapkan) dengan luas lahan 5.000 yang berjumlah 138 tanaman, kemudian dibagi menjadi empat petak secara berjajar. Setiap petak diambil 20 tanaman sampel dengan menggunakan perangkap warna merah, kuning, hijau, dan putih. Peubah yang diamati meliputi komposisi dan kelimpahan arthropoda berdasarkan warna perangkap, indeks similaritas famili antar warna perangkap, serta kepadatan relatif Famili Scolytidae. Hasil penelitian menunjukkan bahwa arthropoda yang ditemukan berjumlah 2.062 individu yang terdiri dari 2 kelas, 12 ordo, dan 72 famili. Ordo Hymenoptera merupakan ordo dengan jumlah individu paling banyak. Perangkap warna kuning merupakan paling banyak memerangkap arthropoda yaitu 552 individu dibandingkan perangkap warna merah, hijau, dan putih yang masing-masingnya hanya 547 individu, 527 individu, dan 436 individu. Nilai indeks similaritas famili arthropoda antar warna perangkap tergolong rendah berarti keragaman famili yang menyusun komunitas tersebut tinggi. Kepadatan Famili Scolytidae berjumlah 0,02 individu/m2 dan kepadatan relatif 0,04%. Hal ini menunjukkan bahwa pengelolaan tanah dan tanamannya secara ekologis masih menguntungkan, tidak mengancam keberlangsungan budi daya tanaman.Preference of Arthropod to Color of Trap on Arabica Coffee Plantation in Atang Jungket Village Aceh Tengah DistrictAbstract. Arthropods are the most dominant phylum among other animal phyla when viewed from the diversity, distribution, and number of species. In arabica coffee plantation there arthropods that act as herbivor, natural enemies, pollinating insects, neutral insects, and decomposers. In general, the management actions carried out by farmers on coffee plantations in Atang Jungket Village, Central Aceh District is to use synthetic pesticides regardless of agro-ecosystem condition. For coffee agro-ecosystem to remain stable and sustainable, it is necessary to do an environmentally friendly management action that is by using color trap where the process of invention of insect host is based on visual factor which aim to know color of trap were liked by arthropod in arabica coffee plantation area. This research uses purposive sampling method with 5,000 land area of 138 plants, then divided into four plots in a row. Each plot was taken 20 sample plants using red, yellow, green, and white traps. The observed variables include the composition and abundance of arthropods based on the trap color, the family similarity index between the trap colors, and the relative density of the Scolytidae Family. The results showed that the arthropods were 2,062 individuals consisting of 2 classes, 12 orders, and 72 families. The Hymenoptera Order is the order of the largest number of individuals. The yellow trap is the most arthropod trap of 552 individuals compared to the red, green, and white traps of 547 individuals, 527 individuals and 436 individuals each. The value of the arthropod family similarity index between the trap colors is low, meaning that the diversity of families that make up the community is high. The Scolytidae Family density was 0.02 individuals/m2 and the relative density was 0.04%. This indicates that the management of land and plants are ecologically still profitable, not threatening the sustainability of cultivation of crops.

Abstract:
Species diversity is a community level characteristic based on species abundance which can be used to describe community structure. Arthropoda is the largest phylum of the animalia kingdom and the number of species in Arthropoda is more than all the species from other phyla. This research is a descriptive explorative research. The aim is to determine the level of diversity and abundance of arthropods in shallot farming land in an effort to prepare ecological practical guidelines. Arthropod species catching technique uses the pitfall trap method. The results of this study were found to be 4 species of arthropods from two classes with a total number of 47 individuals found. The index of diversity of arthropods in shallot farming was low (H' < 3) and the analysis of the abundance index of one species of arthropods had a high abundance index, while the other two species had a moderate abundance index and one species had a low abundance index. The types of arthropods found on shallot farms are: 1) Spodoptera exigua L.; 2) Valanga sp.; 3) Lilioceri L.; and 4) Pass sp. The results of the validation by a team of expert validators and the readability test by 20 students concluded that they did not need revision (80% were in the good category and were suitable for use).

Abstract:
Current concepts of invertebrate phylogeny are reviewed. Annelida and Arthropoda, previously regarded as closely related, are now placed in separate clades. Myelin, a sheath of multiple layers of membranes around nerve axons, is found in members of the Annelida, Arthropoda and Chordata. The structure, composition and function of the sheaths in Annelida and Arthropoda are examined and evidence for the separate evolutionary origins of myelin in the three clades is presented. That myelin has arisen independently at least three times, namely in Annelids, Arthropodas and Chordates, provides a remarkable example of convergent evolution.

Abstract:
Extant arthropods are diverse and ubiquitous, forming a major constituent of most modern ecosystems. Evidence from early Palaeozoic Konservat Lagerstätten indicates that this has been the case since the Cambrian. Despite this, the details of arthropod origins remain obscure, although most hypotheses regard the first arthropods as benthic predators or scavengers such as the fuxianhuiids or megacheirans (‘great-appendage’ arthropods). Here, we describe a new arthropod from the Tulip Beds locality of the Burgess Shale Formation (Cambrian, series 3, stage 5) that possesses a weakly sclerotized thorax with filamentous appendages, encased in a bivalved carapace, and a strongly sclerotized, elongate abdomen and telson. A cladistic analysis resolved this taxon as the basal-most member of a paraphyletic grade of nekto-benthic forms with bivalved carapaces. This grade occurs at the base of Arthropoda (panarthropods with arthropodized trunk limbs) and suggests that arthrodization (sclerotization and jointing of the exoskeleton) evolved to facilitate swimming . Predatory and fully benthic habits evolved later in the euarthropod stem-lineage and are plesiomorphically retained in pycnogonids (sea spiders) and euchelicerates (horseshoe crabs and arachnids).

Abstract:
Spiders are animals that belong to the class Arthropoda phylum Arachnida. Spiders are spread in almost all parts of the world. Spiders can be classified as soil arthropods which are soil-dwelling organisms. The role of arthropods in agro-ecosystems is divided into four, namely as herbivores, decomposers, predators and pollinators. Spiders act as predators. Predatory arthropods are arthropods that eat part or all of their prey's body directly.

Abstract:
In 2010 and 2011, the occurrence of arthropods on apple trees without management was monitored near the village of Velké Bílovice, South Moravia, in two selected localities (an abandoned apple tree orchard and a road apple tree alley). Arthropods in tree tops were killed using deltamehtrin applied with a fogger (Puls Fog). Each collection always contained the material from 5 trees in each site. In 2010, three collections were performed (28/4, 20/5, and 9/7), two in 2011 (11/5 and 23/6). Representatives of eleven orders were captured. Of all the orders trapped, Coleoptera was represented most frequently, the Hymenoptera and Diptera followed. In the alley, individuals of the Coleoptera (34%) were caught most frequently, the Hymenoptera (19.6%) and Hemiptera (17.4%) followed. In the orchard, the Coleoptera (41.4%) was represented most frequently, followed by the Hymenoptera (21.9%) and Diptera (15%). In both the environments, species with negative economic impact were recorded (e.g. Anthonomus pyri, Tatianaerhynchites aequatus, Cydia pomonella, Rhynchites bacchus). However, a greater number of pest antagonists were also found (Scambus pomorum, Coccinella septempunctata, Episyrphus balteatus, Pentatoma rufipes, Orius spp.). Some species were important in faunistic terms, as some critically endangered species were recorded (e.g. Dipoena erythropus, Cryptocephalus schaefferi), and the Plectochorus iwatensis species was recorded for the first time in the Czech Republic.

Abstract:
This article containing information about study of the taxocene Arthropoda is a continuation of the cycle describing the composition of the consortium of the invasive gastropod mollusk Rapana venosa (Valenciennes, 1846). The consortium of R. venosa is still an unaccounted component in the biocenosis structure of the Black Sea shelf. The material used and the research methods are discussed in detail in previous articles of the cycle. The purpose of this work is to describe the complex of epibiontic organisms and to compile an annotated list of Arthropoda taxa of the consortium of R. venosa. The 27 species of phylum Arthropoda found in the consortium belong to two subphyla: Chelicerata (class Arachnida) and Crustacea (classes Malacostraca and Hexanauplia). The only representative of the arachnids class (Arachnida; Acari) – Rhombognathus notops (Gosse, 1855) – was found just twice (in a single specimen in samplings of 2016 and 2017). The shell of R. venosa serves as a substrate for the development of a variety of algae – favorable habitat for the epiphyton, which causes a high number and diversity of crustaceans in this biotope. The greatest taxonomic diversity was noted for the Malacostraca class – 25 species belonging to 22 genera of 19 families. Arthropods are represented in consortium of R. venosa by two main ecological groups – sedentary and mobile epibionts. The largest species diversity of Arthropoda is inherent in free-living mobile forms (23 species). Sedentary forms, which inferior in number of species (4), dominate by quantity (86 %) and biomass (94 %). The only representative of Cirripedia – Amphibalanus improvisus (Darwin, 1854) – is the most common (53 % of the total quantity) and massive crustacean, which contributes the most significant amount to the biomass (91.8 %) of Arthropoda in the consortium. More than 50 % of the Arthropoda species in the consortium are polyphages; phytophages are 20 %; detritophages are 28 % of the total number of arthropod species. The only adult specimen of fish ectoparasites is the isopod Elaphognathia bacescoi (Kussakin, 1969) found in a consortium of sandy rapa-whelk at a depth of 8 m in the Golubaya Bay of Sevastopol. All of the 27 species of Arthropoda found are present in the consortium of the sandy R. venosa, and only 3 species are noted on the rocky rapa-whelks. The differences in the composition of the consortium of the two ecomorphs of R. venosa are mainly due to the great development of the epiphytes and the reduced dynamics of the water masses in the sandy rapa-whelk habitats in Sevastopol region. Due to their taxonomic diversity, quantity and biomass, Arthropoda are an important element of the bottom biocenosis spatially and trophically associated with individuals of the largest gastropod of the Black Sea – R. venosa.

Abstract:
This study was carried out in a woodland on the campus of University of Western Sydney at Richmond, Australia to investigate seasonal effects and recovery speed of arboreal arthropods after disturbance. Twenty one pairs of Melaleuca linariifolia Sm. trees were sampled using insecticide spraying in a log2 nine period sequence (1-32) of weeks supplemented by additional samples to incorporate seasonal (weeks 24 and 48) and annual (week 52) samples. Using species accumulation curves, it was found that four collectors provided a reasonable representation of a tree's fauna and that a single tree does not provide a representative sample of the arthropod fauna found on trees of this species in the study area. The application of richness and evenness indices in different seasons showed significant changes in diversity. It was clear from the findings of the study that careful attention needs to be paid to experimental design. Under replication is the normal situation in previous studies and the effects of location, season and disturbance are all critical factors affecting the estimation of diversity.

Abstract:
Innerhalb der Arthropodensystematik sind die phylogenetischen Beziehungen der höheren Crustaceataxa seit langem von besonderen Interesse. Ziel dieser Arbeit ist die Rekonstruktion der phylogenetischen Verwandtschaftsverhältnisse mit Hilfe molekularer Datensätze für die Phyllopoda, die zusammen mit den Anostraca die Branchiopoda bilden und der Astacoidea (Astacida), einer Teilgruppe der Flusskrebse. Folgende molekulare Marker kamen zum Einsatz: 1) Für die Phyllopoda: Die 3. Domäne der mitochondrial codierten 12S rRNA, unter Berücksichtigung von Sekundärtrukturinformationen, das nukleare Gen EF-1 alpha und die Positionen von Introns im Gen EF-1 alpha. 2) Für die Astacoidea: Die 3. Domäne der 12S rRNA und das mitochondrial codierte Gen cox1. Durch die Wahl der molekularen Marker, die mit unterschiedlichen computerkladistischen Methoden ausgewertet wurden, konnten für die meisten Fragen eine eindeutige und im Fall der Astacoidea überraschende phylogenetische Aussage getroffen werden. Die gewonnenen Hypothesen werden ausführlich im Licht morphologischer Hypothesen diskutiert.
The phylogenetic relationships of the higher arthropod taxa are still of special interest. Especially the interrelationships of the different Crustacea taxa have long been debated. The focus of this investigation is to make a contribution to the phylogenies of two Crustacea taxa using molecular markers: The Phyllopoda which belong together with the Anostraca to the branchiopods, and of the Astacoidea, one of the two higher crayfish taxa (Astacida). The following molecular markers were used: 1) Phyllopoda: the 3rd domain of the mitochondrial encoded 12S rRNA taking into account informations of the secondary structure, the nuclear encoded proteingene EF-1 alpha and the positions of introns found in the coding region of EF-1 alpha. 2) Astacoidea: the 3rd domain of the 12S rRNA and the mitochondrial encoded proteingene cox1. The choice of the mentioned markers in combination with different computercladistical methods allowed to give a satisfying, and in the case of the Astacoidea a more surprising answer to most addressed phylogenetic questions. The gained hypotheses are then discussed in detail in the light of morphological features and hypotheses.

Abstract:
The abundance and diversity of arthropods present in the surface soil layers at various forest sites in northern California were investigated, primarily at two old-growth redwood forest sites in Prairie Creek Redwoods State Park and Jedediah Smith Redwoods State Park. A wide variety of arthropods were found, including representatives of Araneae, Pseudoscorpiones, Opiliones, Acarina, Isopoda, Diplopoda, Chilopoda, Symphyla, Pauropoda, Protura, Diplura, Collembola, Thysanoptera, Hemiptera, Coleoptera, Diptera, and Hymenoptera. Arthropod densities were significantly higher in the wet than in the dry period, indicating seasonal variation in surface densities of soil arthropods. The densities of arthropods in soils collected from beneath coast redwood (Sequoia sempervirens) and western hemlock (Tsuga heterophylla) trees were not significantly different.

ENGLISH ABSTRACT: Within arthropods, inter-individual and inter-population variation is generally poorly explored for physiological parameters. Such physiological variability is important, as it can provide insight into the capacity for evolutionary adaptation and how animals may cope with anthropogenic climate change. Insect vectors of human and animal diseases, such as tsetse flies (Diptera, Glossinidae) which carry trypanosomes, are of particular interest. Predictions of tsetse fly (Glossina spp.) range expansion, possibly paralleled by increased disease occurrence, have been made under future climate scenarios. Moreover, since there are generally strong relationships between abiotic variables (e.g. temperature and moisture availability), population dynamics, distribution and abundance, determining the physiological mechanisms influencing such relationships has utility for predictive modelling of spatial and temporal changes in tsetse fly distributions. I investigated physiological variation among individuals and populations, focusing mainly on Glossina spp. but using other arthropods to address certain issues. Specifically, I show the following: i) metabolic rate is repeatable (intra-class correlation coefficient) within individuals, and may be influenced by several factors such as age, gender, body mass and pregnancy; ii) while metabolic rate is repeatable within individuals, it remains unaltered with acclimation to laboratory conditions from field collection; iii) within a population, metabolic rate-temperature relationships are surprisingly invariant among physiological states such as age, gender, feeding status, pregnancy and temperature acclimation; iv) the magnitude of the effect of temperature acclimation differs among traits, in that upper thermal tolerances respond less than lower thermal tolerances, while metabolic rate responds to heat but not to cold. Water loss rate is relatively unresponsive to either treatment; v) plasticity can account for most inter-population variation in physiological traits related to climatic stress resistance (e.g. thermotolerances and desiccation rates) in the natural environment; vi) adult physiological performance responds differently to developmental and adult acclimation, such that marked traitspecific variation occurs, and combinations of both developmental and adult plasticity can result in further alteration of adult performance. These results have implications for the evolution of stress resistance to abiotic factors in these and other arthropods. I conclude by discussing the potential physiological patterns linking population dynamics and abiotic factors, with particular reference to tsetse flies.
AFRIKAANSE OPSOMMING: Binne arthropoda, is tussen-individu en tussen-bevolking variasie in die algemeen sleg bestudeer vir fisiologiese parameters. Hierdie fisiologiese variasie is belangrik want dit kan insig gee in die mate van evolusionêre aanpassing en hoe diere antropogenies klimaatsverandering kan hanteer. Dit is veral belangrik in die geval van insekte wat mens- en diersiektes kan dra, soos tsetse vlieë (Diptera, Glossinidae) wat trypanosome oordra. In die geval van tsetse vlieë (Glossina spp.) is voorspellings vir verhoogde verspreiding, en gevolglik verhoogde siekte voorkoms, gemaak onder toekomstige voorkoms klimaat senario’s. Verder, aangesien daar in die algemeen sterk verwantskappe tussen abiotiese parameters (bv. temperatuur en water beskikbaarheid), bevolkingsdynamika, verspreiding en voorkoms is, is die bepaling van die fisiologiese meganisme, wat ‘n invloed het op hierdie verwantskappe, nuttig vir die voorspelling van tsetse oor spasie en tyd. Hier, met hoofsaaklik die gebruik van Glossina spp., maar ook ander arthropoda wanneer dit nodig is, word navorsing wat fisiologiese variasie tussen individue en bevolkings aanspreel voorgelê. Spesifiek, word dit gewys dat i) metaboliese tempo is herhaalbaar (intra-klas korrelasie koeffisient) binne individue, alhowel metaboliese tempo kan beinvloed word deur faktore soos ouderdom, geslag, liggaamsmassa en swangerskap, ii) terwyl metaboliese tempo binne individue herhaalbaar is, verander dit nie met akklimasie na laboratorium toestande vanaf versameling in die veld, iii) binne ‘n bevolking metaboliese tempo-temperatuur verwantskappe is verbasend eenders tussen fisiologiese toestande soos ouderdom, geslag, voeding staat, swangerskap en temperatuur akklimasie, iv) die grootte van die effek van temperatuur akklimasie verskil tussen eienskappe, en die boonste termiese limiete reageer minder as laer termiese limiete, terwyl metaboliese tempo reageer op hitte maar nie koue nie, en waterverlies tempo is relatief terughoudend tot enige temperatuur toestand, v) buigbaarheid kan die meeste van inter-bevolkingsvariasie in fisiologiese eienskappe van klimaatstres weerstandsvermoë (termiese toleransie en uitdrogingstempo) in die natuurlike omgewing verklaar, vi) volwasse fisiologiese prestasie reageer verskillend op ontwikkelende en volwasse akklimasie, soveel dat eienskap-spesifieke variasie kan voorkom, en ‘n kombinasie van beide ontwikkelende en volwasse buigbaarheid ‘n verskillende volwasse prestasie tot gevolg kan hê. Hierdie resultate het implikasies vir die evolusie van weerstandsvermoë tot abiotiese faktore in hierdie en ander arthropoda. Hierdie tesis word afgesluit met ‘n bespreeking van die moontlikke fisiologiese patrone wat bevolkingsdinamika en abiotiese faktore kan verbind, met ‘n fokus op tsetse vlieë.

Abstract:
Les pycnogonides sont une classe d’arthropodes marins comptant plus de 1 400 espèces, et dont nous connaissons mal la diversité et l’histoire évolutive. Cette thèse pluridisciplinaire sur les pycnogonides tropicaux s’articule autour de quatre axes de recherche : (i) description de neuf fossiles de Solnhofen (Jurassique supérieur), grâce à une nouvelle technique de visualisation des volumes ; (ii) analyses phylogénétiques des gènes CO1 et 18S à partir de 107 taxons ; (iii) séquençage Illumina par shotgun et assemblage de 103 nouveaux génomes mitochondriaux ; et (iv) taxonomie intégrative des pycnogonides de Martinique reposant sur 803 spécimens collectés lors de l’expédition Madibenthos (2016) et 172 séquences CO1. Tous les fossiles de Solnhofen étudiés sont rattachés aux pantopodes, marquant leur affinité avec la faune moderne. Deux espèces nouvelles sont décrites. Avec les fossiles de La Voulte-sur-Rhône, ils montrent que les pantopodes étaient déjà diversifiés dans des eaux profondes et lagunaires du Jurassique, suggérant une importante transition de faune entre Paléozoïque et Mésozoïque. De nombreux réarrangements du génome mitochondrial, impliquant principalement les gènes des ARNt, sont mis en évidence. Certains sont corrélés à des changements dans le biais de composition en bases qui peuvent impacter la reconstruction phylogénétique. Malgré ces problèmes, nous retrouvons la monophylie de toutes les familles excepté les Ascorhynchidae, Callipallenidae et Nymphonidae, et identifions des regroupements interfamiliaux, d’un côté entre Ammotheidae, Pallenopsidae, Endeidae et Phoxichilidiidae, et de l’autre, entre Callipallenidae et Nymphonidae. Un très grand nombre de relations intergénériques et interspécifiques est également révélé. Alors que 20 espèces étaient auparavant connues sur les côtes de Martinique, cette étude a permis de multiplier par quatre la diversité connue de l’île, soit un total de 73 espèces. Ces résultats suggèrent une diversité encore plus importante à l’échelle des Caraïbes, que l’on pensait pourtant bien explorées
Sea spiders are a class of marine arthropods including more than 1,400 species. Their diversity and evolutionary history are still poorly known. In this thesis, tropical pycnogonids were studied using four approaches: (i) nine fossils from Solnhofen (Upper Jurassic) were examined using a new photographic technic improving visualization of body parts; (ii) for phylogeny, CO1 and 18S genes were analyzed for 107 taxa; (iii) 103 new mitochondrial genomes were assembled after Illumina shotgun sequencing; and (iv) 803 sea spiders collected during the Madibenthos expedition (2016) in Martinique were examined for integrative taxonomy using 172 CO1 sequences.All fossils from Sonhofen are shown to share strong affinities with the modern fauna, as they were identified as belonging to Pantopoda. Two new species are described. Together with fossils from La Voulte-sur-Rhône, these results suggest that Pantopoda were already diversified in shallow and deep Jurassic waters, indicating that an important faunal transition occurred between Palaeozoic and Mesozoic. The mitochondrial genome of sea spiders shows many different gene orders and most of the gene rearrangements involve tRNA genes. Some are correlated with changes in base composition bias, which can be misleading for phylogenetic reconstruction. Despite these problems, all families but Ascorhynchidae, Callipallenidae and Nymphonidae were found to be monophyletic. Furthermore, our analyses provide evidence for several interfamilial relationships (between Ammotheidae, Pallenopsidae, Endeidae and Phoxichilidiidae; and between Callipallenidae and Nymphonidae), and for many intergeneric and interspecific relationships. While only 20 pycnogonid species were previously known from Martinique, the number of species was multiplied by four after our study, i.e. 73. These results suggest that many species still remain to be discovered in the Caribbean Sea, whereas this region was thought to be well-explored regarding sea spiders

Abstract:
Monitoring ecosystems is vital to understanding trends over time and key to detecting change so that managers can address perturbations. Freshwater streams are the lifeblood of the surrounding landscape, and their health is a measure of the overall watershed integrity. Streams are the culmination of upland processes and inputs. Degradation on the landscape as well as changes to the stream itself can be detected using biota living in these ecosystems. Aquatic invertebrates are excellent indicators of ecosystem quality because they are relatively long-lived, sessile, diverse, abundant and their tolerance to perturbation differs. Aquatic invertebrates were monitored at three sites along the Niobrara River at Agate Fossil Beds National Monument in 2019 completing 23 years of data using Hester-Dendy and Hess samplers. Hess samplers are artificial multi-plate samplers suspended in the water column to allow invertebrates to colonize and Hess samples collect invertebrates in a known area on natural substrate and vegetation. We identified 45 invertebrate taxa from four phyla (Annelida, Arthropoda, Mollusca, Nematoda) using both samplers in the Niobrara River (Appendix A and B). Hester-Dendy samplers collected 4 taxa not found in Hess samples and Hess samples collected 17 taxa not collected with Hester-Dendy samplers. Hess samples captured more (91%) than Hester-Dendy samples (62%). Crustacea, Diptera and Ephemeroptera were the most abundant groups of invertebrates collected in the Niobrara River. The proportion of Insecta, Annelida, Trichoptera and Diptera differed between Hester-Dendy and Hess samples (p < 0.05). EPT richness, proportion EPT taxa and Hilsenhoff’s Biotic Index (HBI) (p < 0.0001) differed between sampler types, but taxa richness, taxa diversity and evenness (p > 0.29) did not. We collected the highest density of invertebrates at the Agate Middle site. Agate Spring Ranch had the lowest taxa richness and HBI, and the highest proportion of EPT taxa. HBI at the sites ranged from 4.0 to 6.3 (very good to fair from Hilsenhoff 1987) using the Hester-Dendy and 5.2 to 6.9 (good to fairly poor from Hilsenhoff 1987) using the Hess sampler.
