Pest risk analysis for Bactrocera invadens : Guidelines on Pest Risk Analysis [PDF]

open access: yes, 2010
Stripping related moisture damage has been recognized as one of the major pavement distresses since the early 1990s. The main objective of this study is to establish an effective test protocol to quantify moisture susceptibility of asphalt pavements.

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Differences in cynomolgus macaque populations used for infectious disease research

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Cynomolgus macaques, a species of Old World primate native to southeastern and eastern Asia and the island of Mauritius, are one of the most important nonhuman primate models for infectious disease. Research into the population genetics of cynomolgus macaques has found significant differences between macaques native to different areas, particularly ...

Dynamic evolution of MADS-box genes in extant ferns via large-scale phylogenomic analysis

open access: yesFrontiers in Plant Science
IntroductionSeveral studies of MADS-box transcription factors in flowering plants have been conducted, and these studies have indicated that they have conserved functions in floral organ development; MIKC-type MADS-box genes has been proved to be ...

Between Order and Confusion: Clearing up Structural Misconceptions in Carbon Materials Nomenclature

open access: yesAngewandte Chemie International Edition, EarlyView.
Despite the versatile use of carbon materials, inconsistent terminology and inadequate characterization – especially regarding graphene structures based on sp2‐hybridized carbon atoms – often cause confusion. This perspective clarifies terms like graphite, graphitic carbon, non‐graphitic carbon, and amorphous carbon by aligning IUPAC definitions with X‐

Living in isolation – population structure, reproduction, and genetic variation of the endangered plant species Dianthus gratianopolitanus (Cheddar pink)

open access: yesEcology and Evolution, 2015
The endangered plant species Dianthus gratianopolitanus exhibits a highly fragmented distribution range comprising many isolated populations. Based upon this pattern of distribution, we selected a study region in Switzerland with a lower magnitude of ...
