The range of DNA sequences used to study the interrelationships major arthropod groups (chelicerates, myriapods, hexapods and crustaceans) is limited. Here we investigate value two genes not previously employed in phylogenetics. Histone H3 data were collected for 31 species small nuclear ribonucleic acid U2 29 species. provided a total 460 sites 192 parsimony-informative characters. analyses showed substantial codon usage bias, but had low consistency index (0.26). Consistency indices higher...
Summary An important problem encountered by ecologists in species distribution modelling ( SDM ) and multivariate analysis is that of understanding why environmental responses differ across species, how differences are mediated functional traits. We describe a simple, generic approach to this – the core idea being fit predictive model for abundance (or presence/absence) as function variables, traits their interaction. show method can be understood model‐based fourth‐corner studying...
ABSTRACT We examined the responses of a beetle assemblage to habitat complexity differences within single type, Sydney sandstone ridgetop woodland, using pitfall and flight‐intercept trapping. Six characters (tree canopy cover, shrub ground herb soil moisture, amount leaf litter, logs, rocks debris) were scored between 0 3 ordinal scales reflect at survey sites. Pitfall trapped beetles more species rich different composition in high sites, compared with low Species from Staphylinidae...
Abstract Heteroptera, the true bugs, are part of largest clade non‐holometabolous insects, Hemiptera, and include > 42 000 described species in about 90 families. Despite progress resolving phylogenetic relationships between within infraorders since first combined morphological molecular analysis published 1993 (29 taxa, 669 bp, 31 characters), recent hypotheses have relied entirely on data. Weakly supported nodes along backbone Heteroptera made these phylogenies unsuitable for...
Global conservation assessments require information on the distribution of biodiversity across planet. Yet this is often mapped at a very coarse spatial resolution relative to scale most land-use and management decisions. Furthermore, such mapping tends focus selectively better-known elements (e.g., vertebrates). We introduce new approach describing global terrestrial that may help alleviate these problems. This focuses estimating pattern in emergent properties (richness compositional...
Morphological, developmental, ultrastructural, and gene order characters are catalogued for the same set of arthropod terminals as we have scored in a recent study histone H3 U2 snRNA sequences (D. J. Colgan et al., 1998, Aust. Zool. 46, 419-437). We examine implications separate simultaneous analyses sequence non-sequence data relationships. The most parsimonious trees based on 211 (273 apomorphic states) support traditional higher taxa clades, including Mandibulata, Crustacea, Atelocerata,...
Abstract The Australian insect fauna is highly endemic and characterised by numerous unique higher‐level taxa. In addition, a number of groups are noticeably absent or depauperate on the continent. Many found in Australia show characteristic Gondwanan distribution patterns southern continents. There extensive radiations plant families Myrtaceae Mimosaceae, specialised arid/semiarid fauna, diverse taxa associated with rainforests seasonally wet tropical regions. also poorly studied,...
The morphology of a macropterous form Anommatocoris China is described for the first time, based on bolivianus, new species. Scanning micrographs and line art are provided most aspects external morphology; comparative illustrations members tingid subfamilies Cantacaderinae Tinginae. Characters establishing relationships Vianaidinae with other groups Miroidea sensu Schuh Stys, 1991 analyzed phylogenetically discussed.
Eight new species of the plant bug genus Coridromius are described: C. basilanus sp. nov. from Philippines, eremnos Sabah, Malaysia, fomangsu and tafo Ghana, norfolkensis Norfolk Island, Australia, mulu Sarawak, macchabeeus Mauritius, taravao Tahiti, French Polynesia.
A new genus and species of deraeocorine plant bug, Kalamemiris gen. nov. collessi sp. nov., is described from Australia. Illustrations male genitalia, scanning electron micrographs key characters the female habitus, as well genitalic are provided. The diagnosis made in comparison to other deraeocorines Australian biogeographic region.
Background Later Pleistocene human evolution in East Asia remains poorly understood owing to a scarcity of well described, reliably classified and accurately dated fossils. Southwest China has been identified from genetic research as hotspot diversity, containing ancient mtDNA Y-DNA lineages, yielded number thought derive deposits. We have prepared, reconstructed, described new partial skull consolidated sediment block collected 1979 the site Longlin Cave (Guangxi Province). also undertook...
The Australian endemic staphylinoid plant bug genus Carvalhoma Slater & Gross, 1977 is revised. redescribed and its systematic position within Cylapinae discussed. malcolmae C. taplini are redescribed. Three species, ovatum sp. nov., parvum weiri described as new to science. A key digital habitus images, SEM drawings of male female genitalia distribution map provided.
The Lattinova complex is described, comprising five new genera: Fronsetta, Lattinova, Metopocoris, Sinistropa and Watarrkamiris. All taxa in this are defined by the subrectangular head. species described as to science, includes two of Fronsetta (F. geraldtoni F. maculatus), nine Metopocoris (M. asquithi, M. carnarvoni, cassiae, forresti, joannae, magenta, rubrifasciata, scutata uberini), jacki, four (S. elongatus, S. kulgera, northami rawlinna), Watarrkamiris (W. pallidus W. serpentinae)....
Abstract Macrolophus contains a small group of Palaearctic species with very simple and similar external morphology. The classification these has been based on variable characters such as body measurements, the height black band-shaped macula behind eyes colour first antennal segment. melanotoma (Costa 1853), pygmaeus (Rambur 1839) costalis Fieber 1858, are most reputed predators genus. history M. shows great number misconceptions that have left identity two in confusion. Despite economic...
Abstract The classification of the hyperdiverse true bug family M iridae is far from settled, and particularly contentious for cosmopolitan subfamily B ryocorinae. morphological diversity within pronounced, a lack explicit character formulation hampers stability in classification. Molecular partitions are few only handful taxa have been sequenced. In this study phylogeny ryocorinae has analysed based on data alone, with an emphasis evaluating tribe D icyphina sensu S chuh, 1976, which...
The structure and composition of arthropod assemblages are strongly associated with habitat complexity. Accurate, time efficient estimates complexity may provide insights for biodiversity management in natural systems. We obtained high‐resolution (0.7 m pixel) multi‐spectral aerial imagery National Parks 20 km north south Sydney, Australia. explored both the Normalised Difference Vegetation Index (NDVI) standard deviation reflectance near‐infrared spectrum (stdevR NIR ) as indicators low...
Three recent papers dealing with phylogenetic relationships within the Heteroptera are discussed and analysed. A character set representing 43 taxa 78 characters is used to test theories presented in those papers. The conclusions of Grimaldi Engel concerning placement Cretaceous fossil taxon Cretopiesma Piesmatidae rejected favour Aradidae. by Nel et al. Protodoris from Eocene amber Paris Basin Thaumastocoridae considered ambiguous because it has none diagnostic that family group therefore...
Abstract Sexual conflict has recently been proposed as a driving force behind the rapid diversification of genitalia among sexually reproducing organisms. In traumatically inseminating insects, males stab females in side body with needle‐like genitalia, ejaculating into their cavity. Such mating is costly to and led evolution cost‐reducing ‘paragenitalia’ some species. Whereas consider this evidence antagonistic coevolution, others remain unconvinced. Variation reproductive morphology both...
The genus Thaumastocoris is revised. Nine new species are described (T. busso, T. freomooreae, kalaako, majeri, nadeli, ohallorani, roy, safordi, and slateri) the five previously redescribed. A diagnostic key to provided, supported with illustrations of character systems maps depicting their distributional range. Host plants tabulated, biology host plant associations discussed.
