Multimodal Imaging and Analysis of the Neuroanatomical Organization of the Primary Olfactory Inputs in the Brownbanded Bamboo Shark, .

Front Neuroanat 2020 26;14:560534. Epub 2020 Nov 26.

The Neuroecology Group, UWA Oceans Institute, The University of Western Australia, Perth, WA, Australia.

There is currently a limited understanding of the morphological and functional organization of the olfactory system in cartilaginous fishes, particularly when compared to bony fishes and terrestrial vertebrates. In this fish group, there is a clear paucity of information on the characterization, density, and distribution of olfactory receptor neurons (ORNs) within the sensory olfactory epithelium lining the paired olfactory rosettes, and their functional implications with respect to the hydrodynamics of incurrent water flow into the nares. This imaging study examines the brownbanded bamboo shark (Elasmobranchii) and combines immunohistochemical labeling using antisera raised against five G-protein α-subunits (Gα, Gα, Gα, Gα, Gα ) with light and electron microscopy, to characterize the morphological ORN types present.

Effects of terrigenous organic substrates and additional phosphorus on bacterioplankton metabolism and exoenzyme stoichiometry.

Freshw Biol 2020 Nov 13;65(11):1973-1988. Epub 2020 Jul 13.

Institute of Hydrobiology and Aquatic Ecosystem Management University of Natural Resources and Life Sciences (BOKU) Vienna Austria.

Bamboo, as a pioneer vegetation, often forms forests on bare lands after catastrophic landslides. Compared to evergreen forest soil, bamboo forest soil is much more labile, with a higher percentage of microbially derived organic carbon (OC), lower molecular weight, and lower humic acid content. We hypothesised that different terrigenous organic matter (tOM) sources with varying lability and phosphorus (P) availability select for bacterioplankton with distinct metabolic pathways. Read More

Neotropical Melyroidea group cockroaches reveal various degrees of (eu)sociality.

Naturwissenschaften 2020 Sep 1;107(5):39. Epub 2020 Sep 1.

Institute of Zoology SAS, Dúbravská cesta 9, 845 06, Bratislava, Slovakia.

Eusociality in its various degrees represents an animal social system characterised by cooperative brood care, differentiation into castes and generational overlap. The fossil record indicates that eusociality is likely to have originated in hymenopterans and blattodeans during the Cretaceous. In this study, we present findings from surveys in Peruvian (Villa Carmen) and Ecuadorian (Rio Bigal, El Reventador) cloud forests revealing the first extant cockroach species living in complex, structured groups (n = 90-200 individuals, ˃ 20 adults).

Life history and ecology might explain incongruent population structure in two co-distributed montane bird species of the Atlantic Forest.

Mol Phylogenet Evol 2020 12 6;153:106925. Epub 2020 Aug 6.

Laboratório de Genética e Evolução Molecular de Aves, Departamento de Genética e Biologia Evolutiva, Instituto de Biociências, Universidade de São Paulo, 05508-090 São Paulo, SP, Brazil.

Comparative phylogeography is a powerful approach to investigate the role of historical and environmental processes in the evolution of biodiversity within a region. In this regard, comparative studies of species with similar habitat preferences are valuable to reduce the confounding influence of habitat association when interpreting phylogeographic patterns. In the Atlantic Forest of South America, phylogeographic studies of highland and lowland species have shown distinct population structure patterns so far, suggesting that such species have responded differently to Pleistocene glacial cycles.

TAS2R20 variants confer dietary adaptation to high-quercitrin bamboo leaves in Qinling giant pandas.

Ecol Evol 2020 Jun 4;10(12):5913-5921. Epub 2020 May 4.

Key Laboratory of Animal Ecology and Conservation Biology Institute of Zoology Chinese Academy of Sciences Beijing China.

Sensitivity to bitter tastes provides animals with an important means of interacting with their environment and thus, influences their dietary preferences. Genetic variants encoding functionally distinct receptor types contribute to variation in bitter taste sensitivity. Our previous study showed that two nonsynonymous sites, A52V and Q296H, in the gene are directionally selected in giant pandas from the Qinling Mountains, which are speculated to be the causative base-pair changes of Qinling pandas for the higher preference for bamboo leaves in comparison with other pandas.

Peucedani Radix, derived from roots of Peucedanum praeruptorum Dunn, is a well-known herb used for centuries in traditional Chinese medicine, which is rich in various coumarins. Four different forms including "earthworm head", "bamboo-like", taproots and multi-branched roots have occurred in current producing areas, but the differences in their external features and chemistry have not been concerned till now. In this study, the morphological and microscopic characters of "earthworm head" and "bamboo-like" roots were compared in detail, and qualitative and quantitative characterization of main active coumarins in different forms of Peucedani Radix have been developed by UPCL-Q/TOF-MS and HPLC-DAD, respectively.

DNA barcoding as a valuable molecular tool for the certification of planting materials in bamboo.

3 Biotech 2020 Feb 22;10(2):59. Epub 2020 Jan 22.

1Forest Genetics and Biotechnology Division, Kerala Forest Research Institute, Peechi, Thrissur, Kerala India.

DNA barcodes developed for selected commercially important bamboo species can be utilized for the certification of planting stock in bamboo nurseries in absence of discriminatory features at the juvenile stage. Planting materials such as micropropagated plantlets, rhizome transplants and culm cuttings, generated at nursery level are directly procured for establishment of commercial plantations without any further verification Very often misidentification and mixing up occur at nursery level and the error is not discovered until several years have passed. The present study evaluated the potentiality of seven Consortium for Barcode of Life (CBOL) recommended standard DNA barcode regions in commercially important bamboo species of India. Read More

Mapping thermal conductivity across bamboo cell walls with scanning thermal microscopy.

Sci Rep 2019 11 13;9(1):16667. Epub 2019 Nov 13.

Institute of Wood Technology and Renewable Materials, Department of Material Sciences and Process Engineering, University of Natural Resources and Life Sciences Vienna, Konrad-Lorenz-Strasse 24, 3430, Tulln an der Donau, Austria.

Scanning thermal microscopy is a powerful tool for investigating biological materials and structures like bamboo and its cell walls. Alongside nanoscale topographical information, the technique reveals local variations in thermal conductivity of this elegant natural material. We observe that at the tissue scale, fibre cells in the scattered vascular tissue would offer preferential pathways for heat transport due to their higher conductivities in both anatomical directions, in comparison to parenchymatic cells in ground tissue.

Preparation of Tubular Forest-like and Other Carbon Structures Using Distinct Carbon Sources and Catalyst Concentrations.

Recent Pat Nanotechnol 2020 ;14(2):153-162

Department of Physico-Mathematics, Universidad Autonoma de Nuevo Leon, Ciudad Universitaria, San Nicolas de los Garza, N.L., 66455, Mexico.

Background: In this work, various carbon nanotubes (MWCNTs) were synthetized by the spray pyrolysis method. Resulting nanoforest-like and bamboo-like carbon nanotubes, as well as Yjunctions of carbon nanotubes, possess different shapes and morphology, depending on the kind of carbon source used and on the number of iron particles on the furnace tube surface, which derives from various concentrations of ferrocene catalyst.

Methods: We used the spray pyrolysis method, using different carbon sources (n-pentane, n-hexane, nheptane, and acrylonitrile) as precursors and two different concentrations of ferrocene as a catalyst. Read More

Intra-oropharyngeal food transport and swallowing in white-spotted bamboo sharks.

J Exp Biol 2019 11 22;222(Pt 22). Epub 2019 Nov 22.

Department of Ecology and Evolutionary Biology, Brown University, Providence, RI 02912, USA.

Despite the importance of intraoral food transport and swallowing, relatively few studies have examined the biomechanics of these behaviors in non-tetrapods, which lack a muscular tongue. Studies show that elasmobranch and teleost fishes generate water currents as a 'hydrodynamic tongue' that presumably transports food towards and into the esophagus. However, it remains largely unknown how specific musculoskeletal motions during transport correspond to food motion. Read More
