Natural History and Leaf Shelter Construction of the Asian Rice Leptispa Beetle Leptispa pygmaea Baly (Coleoptera: Chrysomelidae: Cassidinae: Leptispini)
(BioMed Central, 2009-01-15)Kaniyarikkal Divakaran Prathapan, Caroline S. Chaboo, and Kolandaivelu Karthikeyan (2009) Natural history and leaf shelter construction of the Asian rice leptispa beetle, Leptispa pygmaea Baly (Coleoptera: Chrysomelidae: ... -
Phylogenetics of Trachylina (Cnidaria: Hydrozoa) with new insights on the evolution of some problematical taxa
(Cambridge University Press, 2008-09-08)Some of the most interesting and enigmatic cnidarians are classified within the hydrozoan subclass Trachylina. Despite being relatively depauperate in species richness, the clade contains four taxa typically accorded ordinal ... -
Phylogenetics of Hydroidolina (Hydrozoa: Cnidaria)
(Cambridge University Press, 2008-05-08)Hydroidolina is a group of hydrozoans that includes Anthoathecata, Leptothecata and Siphonophorae. Previous phylogenetic analyses show strong support for Hydroidolina monophyly, but the relationships between and within its ... -
Probabilistic Graphical Model Representation in Phylogenetics
(Oxford University Press, 2014-06-20)Recent years have seen a rapid expansion of the model space explored in statistical phylogenetics, emphasizing the need for new approaches to statistical model representation and software development. Clear communication ... -
Diversity and evolution of myxozoan minicollagens and nematogalectins
(BioMed Central, 29-09-20)Background Myxozoa are a diverse group of metazoan parasites with a very simple organization, which has for decades eluded their evolutionary origin. Their most prominent and characteristic feature is the polar capsule: ... -
Phylogeny and Niche Conservatism in North and Central American Triatomine Bugs (Hemiptera: Reduviidae: Triatominae), Vectors of Chagas' Disease
(Public Library of Science, 2014-10-30)The niche conservatism hypothesis states that related species diverge in niche characteristics at lower rates than expected, given their lineage divergence. Here we analyze whether niche conservatism is a common pattern ... -
A Whole-Chromosome Analysis of Meiotic Recombination in Drosophila melanogaster
(Genetics Society of America, 2012-02-01)Although traditional genetic assays have characterized the pattern of crossing over across the genome in Drosophila melanogaster, these assays could not precisely define the location of crossovers. Even less is known about ... -
Warming-enhanced preferential microbial mineralization of humified boreal forest soil organic matter: Interpretation of soil profiles along a climate transect using laboratory incubations
(Wiley, 2012-06-01)Humified soil organic matter storage in boreal forests is large, and its responses to warming over relatively long timescales is critical for predicting soil feedbacks to climate change. To derive information relevant ... -
Wing Shape of Four New Bee Fossils (Hymenoptera: Anthophila) Provides Insights to Bee Evolution
(Public Library of Science, 2014-10-29)Bees (Anthophila) are one of the major groups of angiosperm-pollinating insects and accordingly are widely studied in both basic and applied research, for which it is essential to have a clear understanding of their ... -
Fitness of Crop-Wild Hybrid Sunflower under Competitive Conditions: Implications for Crop-to-Wild Introgression
(Public Library of Science, 2014-10-08)Understanding the likelihood and extent of introgression of novel alleles in hybrid zones requires comparison of lifetime fitness of parents and hybrid progeny. However, fitness differences among cross types can vary ... -
Mapping the Potential Risk of Mycetoma Infection in Sudan and South Sudan Using Ecological Niche Modeling
(Public Library of Science, 2014-10-16)In 2013, the World Health Organization (WHO) recognized mycetoma as one of the neglected tropical conditions due to the efforts of the mycetoma consortium. This same consortium formulated knowledge gaps that require further ... -
An orchid bee of the genus Eulaema in Early Miocene Mexican amber (Hymenoptera: Apidae)
(University of Kansas, 2014-05-20)The first fossil orchid bee from Early Miocene Mexican amber is described and figured. Eulaema (Apeulaema) zigrasi Engel, new species, represents the first non-meliponine bee fossil documented from Mexican amber as well ... -
Revision of the bee genus Chlerogella (Hymenoptera: Halictidae), Part IV: A new species from southwestern Colombia
(University of Kansas, 2014-05-29)A new species of the diverse augochlorine bee genus Chlerogella Michener (Halictinae: Augochlorini) is described and figured from southwestern Colombia. Chlerogella anchicaya Engel, Gonzalez, & Hinojosa-Díaz, new species, ... -
The vertebrate taxonomy ontology: a framework for reasoning across model organism and species phenotypes
(BioMed Central, 2013-11-22)A hierarchical taxonomy of organisms is a prerequisite for semantic integration of biodiversity data. Ideally, there would be a single, expansive, authoritative taxonomy that includes extinct and extant taxa, information ... -
A new species of the cleptoparasitic bee genus Thyreus from northern Yemen and southwestern Saudi Arabia (Hymenoptera, Apidae)
(Pensoft Publishers, 2014-07-23)A new species of cleptoparasitic bee of the genus Thyreus Panzer (Apinae: Melectini) is described and figured from northern Yemen and southwestern Saudi Arabia. Thyreus shebicus Engel, sp. n. is a relatively small species ... -
