Ancient DNA of the pygmy marmoset type specimen Cebuella pygmaea (Spix, 1823) resolves a taxonomic conundrum

The pygmy marmoset, the smallest of the anthropoid primates, has a broad distribution in Western Amazonia. Recent studies using molecular and morphological data have identified two distinct species separated by the Napo and Solimões-Amazonas rivers. However, reconciling this new biological evidence with current taxonomy, i.e., two subspecies, Cebuella pygmaea pygmaea (Spix, 1823) and Cebuella pygmaea niveiventris (Lönnberg, 1940), was problematic given the uncertainty as to whether Spix's pygmy marmoset (Cebuella pygmaea pygmaea) was collected north or south of the Napo and Solimões-Amazonas rivers, making it unclear to which of the two newly revealed species the name pygmaea would apply. Here, we present the first molecular data from Spix's type specimen of Cebuella pygmaea, as well as novel mitochondrial genomes from modern pygmy marmosets sampled near the type locality (Tabatinga) on both sides of the river. With these data, we can confirm the correct names of the two species identified, i.e., C. pygmaea for animals north of the Napo and Solimões-Amazonas rivers and C. niveiventris for animals south of these two rivers. Phylogenetic analyses of the novel genetic data placed into the context of cytochrome b gene sequences from across the range of pygmy marmosets further led us to reevaluate the geographical distribution for the two Cebuella species. We dated the split of these two species to 2.54 million years ago. We discuss additional, more recent, subdivisions within each lineage, as well as potential contact zones between the two species in the headwaters of these rivers

Relationship between freight accessibility and logistics employment in US counties

This paper analyzes the relationship between freight accessibility and logistics employment in the US. It develops an accessibility measure relevant for logistics companies based on a gravity model. This allows for an analysis of the accessibility of US counties focusing on four different modes of transportation: road, rail, air, and maritime. Using a Partial Least Squares model, these four different freight accessibility measures are combined into two constructs, continental and intercontinental freight accessibility, and related to logistics employment. Results show that highly accessible counties attract more logistics employment than other counties. The analyses show that it is very important to control for the effect of the county population on both freight accessibility and logistics employment. While county population explains the most variation in the logistics employment per county, there is a significant relationship between freight accessibility and logistics employment, when controlling for this effect

The Impact of Symbolic and Substantive Actions on Environmental Legitimacy

Drawing on institutional theory and insights from stakeholder theory and impression management, we empirically analyze the impact of both environmental symbolic polices (participation in voluntary environmental programs, green trademarks, environmental-dedicated board committees, environmental pay policies and community communication) and substantive actions (environmental patents and pollution prevention practices) on environmental legitimacy. We show that (1) symbolic actions have a weaker positive effect on legitimacy than substantive actions, (2) that the impact of symbolic actions is greater when they are combined with substantive actions, (3) that this impact is only short-term while substantive actions have both short- and long-term effects

Taxonomic diversity of Cebuella in the western Amazon: Molecular, morphological and pelage diversity of museum and free- ranging specimens

ObjectivesWe investigated the diversity of the pygmy marmoset, Cebuella pygmaea, by comparing genetic, morphological and pelage traits of animals from Peru and Ecuador.Materials and MethodsWe extracted DNA from museum specimen osteocrusts and from fecal samples collected from free- ranging individuals. We sequenced the mtDNA cytochrome b gene and the control region from samples collected at 13 different sites and used Bayesian inference and Maximum Likelihood to identify distinct clades. We took measurements of the crania of a subset of these specimens (n = 26) and ran a logistic regression to determine if any of the cranial measurements (n = 22) could predict a specimen’s clade. In addition, we examined the pelage patterns of the museum specimens and photographs taken of free- ranging individuals and divided them into pelage types based on coloration of the underbelly.ResultsWe identified two divergent clades, and two distinct groups with clear geographic boundaries within one of those clades. Two measurements of the zygomatic bone perfectly predicted a given individual’s mtDNA clade. We found four distinct pelage patterns in our samples, but these patterns are variable within clades and among individuals within the same population.ConclusionThese analyses indicate that the two recognized subspecies of pygmy marmoset should be elevated to the species level (C. pygmaea and C. niveiventris) based on molecular and cranial differences but not on pelage patterns. We provide evidence on the geographic limits of the two clades and identify regions where additional sampling is required to better define the geographic distribution of the two clades.Although white- bellied marmosets are common in southern Ecuador and Peru and belong to the same mtDNA haplotype, individuals vary considerably in their belly color even in the same population, like in these two individuals at the Tiputini Biodiversity Station, Ecuador.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/167477/1/ajpa24266_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/167477/2/ajpa24266.pd

Identification of technology development trends based on subject–action–object analysis: The case of dye-sensitized solar cells

International audienceIdentification of technology development trends is essential for supporting decision-makers in forecasting and identifying related innovation activities as well the industrial growth. In difference of the traditional technology development trends based on SAO, which usually predicting the trend by finding key problems and technologies used to resolve them, the method proposed in this paper allows to identify what industry goal can be achieved by the interaction between the problems and technologies, the detailed paths to achieve it and the key countries which can encourage the trend by engaging technological innovation scenarios. This method builds a technology roadmapping (TRM) with seven layers based on Subject-Action-Object (SAO) analysis, which is composed by material, technology, influencing factor, component, product, goal and application area. It is a combination of vertical and horizontal TRM and has the advantages of both of them. Comparing with the existing technology roadmapping, this method indicates not only the development paths of the key technologies but also those of them that are most opportune to resolve the specific problem and achieve the particular industry goal. Furthermore, with the intention to identify the key countries supporting the technological development, this method sets three indicators acting as the discriminating standards. To demonstrate the effectiveness of the method, this paper presents a case study of literature related to dye-sensitized solar cells. The result reveals the industry goal and trends in the field of DSSCs, in addition, it can identify the detail approach of the trends and the key countries to support it
