The art and science of species delimitation

引用

Current Zoology 2015年第5期61卷 846-853页

作者： bruce RANNALA Department of Evolution and Ecology University of California Davis Davis CA 95616 USA

DNA-based approaches to systematics have changed dramatically during the last two decades with the rise of DNA barcoding methods and newer multi-locus methods for species delimitation. During the last half-decade, partly driven by the new sequencing technologies, the focus has shifted to multi-locus sequence data and the identification of species within the frame-work of the multi-species coalescent （MSC）. In this paper, I discuss model-based Bayesian methods for species delimitation that have been developed in recent years using the MSC. Several approximate methods for species delimitation （and their limitations） are also discussed. Explicit species delimitation models have the advantage of clarifying more precisely what is being delimited and what assumptions we are making in doing so. Moreover, the methods can be very powerful when applied to large multi-locus datasets and thus take full advantage of data generated using today＇s technologies [Current Zoology 61 （5）： 846-853,2015].

New microsome-associated HT-family proteins from Nicotiana respond to pollination and define an HT/NOD-24 protein family

引用

Molecular Plant 2008年第4期1卷 634-644页

作者： Katsuhiko Kondo bruce McClure Department of Biochemistry Interdisciplinary Plant Group and the Christopher S. Bond Life Sciences Center University of Missouri MI USA

HT-family proteins have been identified in Nicotiana, Solanum, and Petunia. HT-B-type proteins are implicated in S-RNase-based self-incompatibility, but the functions of other family members are unknown. Screening for cDNA sequences with an expression pattern similar to HT-B in Nicotiana alata revealed a new group of small HT-family proteins, designated HT-M. HT-M proteins resemble HT-B in several respects： their pistil-specific expression pattern is indistinguishable from HT-B, they pellet with a microsome fraction, and their abundance decreases after pollination. Unlike HT-B, there is no S-specificity to this response, and RNAi experiments show that HT-M proteins are not necessary for self-incompatibility. Identification of a third group of pistil-specific HT-family proteins helps better define the characteristics of the family and allowed identification of putative new family members. By searching the databases with only the most conserved HT- family sequence elements, the signal sequence and cysteine motifs, we identified nodulin-24-1ike proteins and several small glycine-rich proteins as putative HT-family members. Like HT-M and HT-B, nodulin-24 is membrane associated. We propose that the conserved features in HT-family proteins are important for targeting or modification and refer to the broader family that includes both HT- and nodulin-24-1ike proteins as the HT/NOD-24-family.

A review of the geomechanics aspects of a double fatality coal burst at Austar Colliery in NSW,Australia in April 2014

引用

International Journal of Mining Science and Technology 2017年第1期27卷 3-7页

作者： Hebblewhite bruce Calvin Jim School of Mining Engineering UNSWSydney 2052Australia

A coal burst occurred on 15 April, 2014 at the Austar Coal Mine, located west of Newcastle, NSW,Australia. The burst resulted in fatal injuries to two men working as part of the mining crew at the development face. At the time, a continuous miner was being used to mine a longwall development gate road through heavily structured coal, at a depth of approximately 550 m. A number of pre-cursor bumps had occurred on previous shifts, emanating from the coal ribs of the roadway, in proximity to the coal *** paper reviews the geological, geotechnical and mining conditions and circumstances leading up to the coal burst event; and presents and discusses the available evidence and possible interpretations relating to the geomechanical behaviour mechanisms that may have been critical factors in this incident. The paper also discusses some key technical and operational considerations of ground support systems and mining practices and strategies needed for operating in such conditions in the future.

Two different mathematical schemes for solving chemical dissolution-front instability problems in fluid-saturated rocks

Chemical dissolution-front instability(CDFI)problems usually involve multiple temporal and spatial scales,as well as multiple processes.A key issue associated with solving a CDFI problem in a fluid-saturated rock is to mathematically establish a theoretical criterion,which can be used to judge the instability of a chemical dissolution-front(CDF)propagating in the fluidsaturated *** theoretical paper deals with how two different mathematical schemes can be used to precisely establish such a theoretical criterion in a purely mathematical manner,rather than in a numerical simulation *** main distinguishment between these two different mathematical schemes is that in the first mathematical scheme,a curved surface coordinate system is used,while in the second mathematical scheme,a planar surface coordinate system is *** particular,all the key mathematical deduction steps associated with using these two different mathematical schemes are described and discussed in great *** main theoretical outcomes of this study have demonstrated that(1)two different mathematical schemes under consideration can produce exactly the same theoretical criterion;(2)the main advantage of using the first mathematical scheme is that the interface conditions at the curved interface between the downstream and upstream regions can be easily described mathematically;(3)the main advantage of using the second mathematical scheme is that the first-order perturbation equations of the CDFI problem can be easily described in a purely mathematical manner.
