Environ Pollut 2018 Dec 7;246:328-335. Epub 2018 Dec 7.

State Key Laboratory of Organic Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou, 510640, China.

The occurrence and distributions of selected endocrine-disrupting chemicals (EDCs), along with related environmental factors, were investigated in two rivers and six reservoirs in the Pearl River Delta. The vertical profiles of aqueous 4-tert-octylphenol (OP), 4-nonylphenol (NP), and estrone (E1) were constant, with little change in concentration between the surface and the river bottom, while higher aqueous concentrations of bisphenol A (BPA) were found in the bottom layers of the rivers. OP and NP in suspended particulate matter (SPM) were transferred from the surface to the bed layer, ultimately accumulating in the sediment. Read More

Predicting cadmium toxicity with the kinetics of phytochelatin induction in a marine diatom.

Aquat Toxicol 2018 Dec 11;207:101-109. Epub 2018 Dec 11.

Key Laboratory of Tropical Marine Bio-resources and Ecology, Guangdong Provincial Key Laboratory of Applied Marine Biology, South China Sea Institute of Oceanology, Chinese Academy of Sciences, Guangzhou, 510301, China. Electronic address:

Phytochelatin (PC) synthesis is thought to be a rapid and specific response to metal exposure in marine phytoplankton, but its potential as a predictor of metal toxicity is far from conclusive. Thus this research examines the bioaccumulation, PC induction, and toxicity of Cadmium (Cd) in Thalassiosira weissflogii, a coastal diatom under varying nutrient conditions. Nitrogen limitation strongly inhibited Cd uptake and PC induction at the same [Cd] level, and increased metal sensitivity. Read More

Evolution of maternal and zygotic mRNA complements in the early Drosophila embryo.

PLoS Genet 2018 Dec 17;14(12):e1007838. Epub 2018 Dec 17.

Department of Evolution and Ecology, University of California, Davis, Davis, California, United States of America.

The earliest stage of animal development is controlled by maternally deposited mRNA transcripts and proteins. Once the zygote is able to transcribe its own genome, maternal transcripts are degraded, in a tightly regulated process known as the maternal to zygotic transition (MZT). While this process has been well-studied within model species, we have little knowledge of how the pools of maternal and zygotic transcripts evolve. Read More

J Wildl Dis 2018 Dec 17. Epub 2018 Dec 17.

1 Tarleton State University, Department of Biological Sciences, Box T-0100, Stephenville, Texas 76402, USA.

Reticuloendotheliosis virus (REV) is an immunosuppressive and sometimes oncogenic avian retrovirus that establishes lifelong infection in a wide range of avian species. REV-infected wild birds roaming near at-risk captive flocks, such as is the case for the highly endangered Attwater's prairie chicken ( Tympanuchus cupido attwateri; APC), could act as a reservoir for viral transmission. In wild birds, prevalence rates of REV are low and appearance of associated disease is uncommon. Read More

Investigation of deleterious effects of nsSNPs in the POT1 gene: a structural genomics-based approach to understand the mechanism of cancer development.

J Cell Biochem 2018 Dec 16. Epub 2018 Dec 16.

Centre for Interdisciplinary Research in Basic Sciences, Jamia Millia Islamia, New Delhi, India.

Protection of telomere 1 (POT1) is one of the key components of shelterin complex, implicated in maintaining the telomere homeostasis, and thus stability of the eukaryotic genome. A large number of non-synonymous single nucleotide polymorphisms (nsSNPs) in the POT1 gene have been reported to cause varieties of human diseases, including cancer. In recent years, a number of mutations in POT1 has been markedly increased, and interpreting the effect of these large numbers of mutations to understand the mechanism of associated diseases seems impossible using experimental approaches.

Centro de Investigación en Ciencias Biológicas Aplicadas, Universidad Autónoma del Estado de México, Instituto Literario # 100, Colonia Centro, Toluca, Estado de México, CP 50000, México.

The isolated and fragmented populations are highly susceptible to stochastic events, increasing the extinction risk because of the decline in putative adaptive potential and individual fitness. The population has high heterozygosity values and a moderate allelic diversity, the heterozygosity values are higher than in most other species and snake studies. Possibly these high levels of genetic diversity can be related to a large founder size, high effective population size, multiple paternity and overlapping generations. Read More

Much progress has been made improving animal welfare in conservation over the past two decades. However, several glaring knowledge gaps remain where animal welfare concerns exist but animal welfare studies have not been performed in politically sensitive contexts. We use examples from Australia to identify four such issues lacking meaningful analysis; the absence of animal welfare oversight for operations designated as "management" (as opposed to research), the lack of consideration for the animal welfare impacts of biological agents that are used to control invasive animals, the paucity of studies to examine the welfare of animals that are hunted recreationally, and the scarcity of studies to examine the animal welfare impacts associated with Indigenous wildlife use.

Climate change impact and adaptation for wheat protein.

Glob Chang Biol 2019 Jan 22;25(1):155-173. Epub 2018 Nov 22.

Institute of Crop Science and Resource Conservation INRES, University of Bonn, Bonn, Germany.

Wheat grain protein concentration is an important determinant of wheat quality for human nutrition that is often overlooked in efforts to improve crop production. We tested and applied a 32-multi-model ensemble to simulate global wheat yield and quality in a changing climate. Potential benefits of elevated atmospheric CO concentration by 2050 on global wheat grain and protein yield are likely to be negated by impacts from rising temperature and changes in rainfall, but with considerable disparities between regions.

The centrality of health behaviours: A network analytic approach.

Br J Health Psychol 2018 Dec 13. Epub 2018 Dec 13.

School of Psychological Sciences, Tel Aviv University, Israel.

Objectives: Since behavioural risk factors are the foremost causes of disability and premature mortality, developing new perspectives for understanding them is of utmost importance. This paper describes an innovative approach that conceptualizes health-related behaviours as nodes in a weighted network.

Design & Methods: Using self-reported data from a representative sample (n = 374), a network of 37 health behaviours was analysed, with the aim of identifying 'central' nodes, that is, behaviours that are likely to co-occur with others and potentially influence them. Read More

Behavioral and endocrine correlates of dominance in captive female Jackson's hartebeest (Alcelaphus buselaphus).

Zoo Biol 2018 Dec 13. Epub 2018 Dec 13.

Department of Biology, Georgia Southern University, Statesboro, Georgia.

For species that form dominance hierarchies, such as group-living ungulates, aggressive interactions can pose a challenge to successful captive management. For example, Jackson's hartebeest (Alcelaphus buselaphus), a rare antelope of east Africa, can be difficult to maintain in captivity because aggression within female dominance hierarchies can lead to injury and death. We quantified behavioral and endocrine correlates of dominance in a captive herd of ten female hartebeest with the goal of understanding how to minimize dangerous interactions. Read More

Direct and indirect effects of climate on richness drive the latitudinal diversity gradient in forest trees.

Ecol Lett 2018 Dec 12. Epub 2018 Dec 12.

ECNU-Alberta Joint Lab for Biodiversity Study, Tiantong National Station for Forest Ecosystem Research, East China Normal University, 200241, Shanghai.

Climate is widely recognised as an important determinant of the latitudinal diversity gradient. However, most existing studies make no distinction between direct and indirect effects of climate, which substantially hinders our understanding of how climate constrains biodiversity globally. Using data from 35 large forest plots, we test hypothesised relationships amongst climate, topography, forest structural attributes (stem abundance, tree size variation and stand basal area) and tree species richness to better understand drivers of latitudinal tree diversity patterns.

Developing a list of invasive alien species likely to threaten biodiversity and ecosystems in the European Union.

Glob Chang Biol 2018 Dec 12. Epub 2018 Dec 12.

Environment Agency Austria, Vienna, Austria.

The European Union (EU) has recently published its first list of invasive alien species (IAS) of EU concern to which current legislation must apply. The list comprises species known to pose great threats to biodiversity and needs to be maintained and updated. Horizon scanning is seen as critical to identify the most threatening potential IAS that do not yet occur in Europe to be subsequently risk assessed for future listing. Read More

Proximity to canopy mediates changes in the defensive chemistry and herbivore loads of an understory tropical shrub, Piper kelleyi.

Ecol Lett 2018 Dec 12. Epub 2018 Dec 12.

Ecology, Evolution, and Conservation Biology, University of Nevada, Reno, Reno, NV, 89557, USA.

Phytochemical traits are a key component of plant defense theory. Chemical ecology has been biased towards studying effects of individual metabolites even though effective plant defenses are comprised of diverse mixtures of metabolites. We tested the phytochemical landscape hypothesis, positing that trophic interactions are contingent upon their spatial location across a phytochemically diverse landscape. Read More

Declining population trends of European mountain birds.

Glob Chang Biol 2018 Dec 11. Epub 2018 Dec 11.

Dachverband Deutscher Avifaunisten (DDA) e.V., Geschäftsstelle, Münster, Germany.

Mountain areas often hold special species communities, and they are high on the list of conservation concern. Global warming and changes in human land use, such as grazing pressure and afforestation, have been suggested to be major threats for biodiversity in the mountain areas, affecting species abundance and causing distribution shifts towards mountaintops. Population shifts towards poles and mountaintops have been documented in several areas, indicating that climate change is one of the key drivers of species' distribution changes. Read More
