Typhoon frequency and intensity across the Western Pacific Ocean north of the Equator, 1951 – 2014
(Computer Network Information Center, 2017-10-20)Disturbance has been a repeated theme in ecology in recent decades, yet incorporating its frequency and pattern at broad spatial scales into ecological analyses has been difficult – rather, most environmental datasets used ... -
Changes in biomass allocation buffer low CO2 effects on tree growth during the last glaciation
(Nature Research, 2017-02-24)Isotopic measurements on junipers growing in southern California during the last glacial, when the ambient atmospheric [CO2] (ca) was ~180 ppm, show the leaf-internal [CO2] (ci) was approaching the modern CO2 compensation ... -
Conserved Patterns of Sex Chromosome Dosage Compensation in the Lepidoptera (WZ/ZZ): Insights from a Moth Neo-Z Chromosome
(Oxford University Press, 2017-03-01)Where previously described, patterns of sex chromosome dosage compensation in the Lepidoptera (moths and butterflies) have several unusual characteristics. Other female-heterogametic (ZW/ZZ) species exhibit female Z-linked ... -
Contrasting patterns of evolutionary constraint and novelty revealed by comparative sperm proteomic analysis in Lepidoptera
(BMC, 2017-12-02)Background: Rapid evolution is a hallmark of reproductive genetic systems and arises through the combined processes of sequence divergence, gene gain and loss, and changes in gene and protein expression. While studies ... -
Multidimensional metrics of niche space for use with diverse analytical techniques
(Nature Research, 2017)Multidimensional data are integral to many community-ecological studies and come in various forms, such as stable isotopes, compound specific analyses (e.g., amino acids and fatty acids), and both biodiversity and life ... -
Potential distribution of mosquito vector species in a primary malaria endemic region of Colombia
(Public Library of Science, 2017-06-08)Rapid transformation of natural ecosystems changes ecological conditions for important human disease vector species; therefore, an essential task is to identify and understand the variables that shape distributions of these ... -
Phylogeography of Rift Valley Fever Virus in Africa and the Arabian Peninsula
(Public Library of Science, 2017-01-09)Rift Valley Fever is an acute zoonotic viral disease caused by Rift Valley Fever virus (RVFV) that affects ruminants and humans in Sub-Saharan Africa and the Arabian Peninsula. We used phylogenetic analyses to understand ... -
Automated identification of insect vectors of Chagas disease in Brazil and Mexico: the Virtual Vector Lab
(PeerJ, 2017-04-18)Identification of arthropods important in disease transmission is a crucial, yet difficult, task that can demand considerable training and experience. An important case in point is that of the 150+ species of Triatominae, ... -
Assessing Monkeypox Virus Prevalence in Small Mammals at the Human-Animal Interface in the Democratic Republic of the Congo
(MDPI, 2017-10-03)During 2012, 2013 and 2015, we collected small mammals within 25 km of the town of Boende in Tshuapa Province, the Democratic Republic of the Congo. The prevalence of monkeypox virus (MPXV) in this area is unknown; however, ... -
Reconstructing the geographic origin of the New World jays
(Taylor & Francis Open, 2017-03-05)We conducted a biogeographic analysis based on a dense phylogenetic hypothesis for the early branches of corvids, to assess geographic origin of the New World jay (NWJ) clade. We produced a multilocus phylogeny from sequences ... -
Ecological niche model comparison under different climate scenarios: a case study of Olea spp. in Asia
(Ecological Society of America, 2017-05-19)Ecological niche modeling (and the related species distribution modeling) has been used as a tool with which to assess potential impacts of climate change processes on geographic distributions of species. However, the ... -
Effects of Clonal Reproduction of Evolutionary Lag and Evolutionary Rescue
(University of Chicago Press, 2017-08-11)Evolutionary lag—the difference between mean and optimal phenotype in the current environment—is of keen interest in light of rapid environmental change. Many ecologically important organisms have life histories that include ... -
Are fundamental niches larger than the realized? Testing a 50-year-old prediction by Hutchinson
(Public Library of Science, 2017-04-12)For more than 50 years ecological niches have been defined as combinations of multidimensional environmental conditions permitting a species to survive and reproduce. A fundamental niche (NF) is defined as the set of ... -
New species of Southeast Asian Dwarf Tarantula from Thailand: Phlogiellus Pocock, 1897 (Theraphosidae, Selenocosmiinae)
(Pensoft Publishers, 2017-07-11)A new record of the tarantula genus Phlogiellus Pocock, 1897 from Thailand is described. Distributional data, natural history, morphological characters, and illustrations of male and female are provided. The Thai specimens ... -
Revision of the Neotropical water scavenger beetle genus Quadriops Hansen, 1999 (Coleoptera, Hydrophilidae, Acidocerinae)
(Pensoft Publishers, 2017-10-03)The genus Quadriops Hansen, 1999 is revised and redescribed. The genus is found to contain six species, including two that are here described as new: Quadriops clusia sp. n. (Brazil, Guyana, Suriname) and Q. acroreius sp. ... -
Revision of the Neotropical water scavenger beetle genus Tobochares Short & García, 2007 (Coleoptera, Hydrophilidae, Acidocerinae)
(Pensoft Publishers, 2017-04-21)The genus Tobochares Short & García, 2007 is revised. A combination of morphological and molecular data provide support for ten distinct species. Five new species are described: T. canaliculatus sp. n. (Venezuela), T. ... -
Assessing the Influence of Temporal Autocorrelations on the Population Dynamics of a Disturbance Specialist Plant Population in a Random Environment
(University of Chicago Press, 2017-08-07)Biological populations are strongly influenced by random variations in their environment, which are often autocorrelated in time. For disturbance specialist plant populations, the frequency and intensity of environmental ... -
Disc-shaped fossils resembling porpitids or eldonids from the early Cambrian (Series 2: Stage 4) of western USA
(PeerJ, 2017-06-06)The morphology and affinities of newly discovered disc-shaped, soft-bodied fossils from the early Cambrian (Series 2: Stage 4, Dyeran) Carrara Formation are discussed. These specimens show some similarity to the Ordovician ... -
The dogs of Roman Vindolanda: Quantifying juvenilization and pleiotropic effects of miniaturization.
(2018-11)In this report we focus on harriers, small dogs of gracile build widely represented in Roman artwork, yet not previously documented from skull or skeletal material. With them we compare remains of other types of small dogs ... -
The potential role of hybridization in diversification and speciation in an insular plant lineage: insights from synthetic interspecific hybrids
(Oxford University Press, 2017-09-01)Hybridization is recognized as an important process in plant evolution, and this may be particularly true for island plants where several biotic and abiotic factors facilitate interspecific hybridization. Although rarely ...
