Paper: Interisland genetic structure of two endangered Hawaiian waterbirds: The Hawaiian Coot and Hawaiian Gallinule

http://www.bioone.org/doi/10.1650/CONDOR-18-98.1


Current distribution (shaded in gray), sample size, and average membership coefficient of individual Hawaiian Coots (A) and Hawaiian Gallinules (B) from sampled Hawaiian islands into the 2 clusters inferred from 16 and 13 microsatellite loci, respectively, in Structure (Pritchard et al. 2000).

Paper: Evaluating a focal-species approach for tidal marsh bird conservation in the northeastern United States

http://www.bioone.org/doi/10.1650/CONDOR-18-88.1


Delineation of 8 tidal marsh subregions in northeastern North America (after Wiest et al. 2016), with location of the study region in the United States (inset). The table shows total number of patches, mean cost of land purchase (U.S. dollars ha−1), and area (ha) for each subregion.

Can vultures help us avoid food poisoning?

https://www.mdlinx.com/internal-medicine/article/2888


Bald is beautiful? What's in a vulture's digestive system that enables it to eat dead meat without getting sick?


Abstract: A Systematic Review of Carrion Eaters' Adaptations to Avoid Sickness

Paper: The microbiome of New World vultures

https://www.nature.com/articles/ncomms6498


(a) Microbial clustering on the basis of Bray?Curtis dissimilarity matrix (visualized by principal coordinate analysis). Facial skin and hindgut communities exhibited minor overlap (ANOSIM; R=0.744, P=0.001). Hindgut (ANOSIM, R=0.333, P=0.001) and skin (ANOSIM, R=0.321, P=0.001) communities showed minor clustering within vulture species. (b) Variation in diversity (Shannon index) in facial skin and hindgut. The hindgut community was significantly less diverse than the facial community (Wilcoxon Rank-Sum test, P≪0.001). The facial communities of the black vulture were more diverse than those of the turkey vulture whereas the hindgut samples displayed the opposite pattern (Wilcoxon Rank-Sum test, P≪0.01). There were no differences between male and female vultures in the clustering (not shown) of hindgut (ANOSIM, R=0.063, P>0.05) or facial (ANOSIM, R=0.025, P>0.05) communities.

Dinosaurs may have had bird-like 'superlungs'

Paper: Vertebral morphometrics and lung structure in non-avian dinosaurs

http://rsos.royalsocietypublishing.org/content/5/10/180983


File photo - A robotic Velociraptor dinosaur opens its mouth to scare visitors as it demonstrates the power of air pressure at the fluid power exhibition in Tokyo on April 22, 2008. The dinousaur, produced by Japanese robotic venture Kokoro, has an infrared sensor to detect passersby. (Photo credit should read YOSHIKAZU TSUNO/AFP/Getty Images)


Anatomy of the lung and thorax of extant archosaurs. (a) Dorsal view of the lungs and trachea of a hatchling American alligator (Alligator mississippiensis) generated from microCT. (b) Lungs of a hatchling A. mississippiensis in association with the vertebral column and dorsal ribs in left anterolateral view. (c) Interior of the thoracic cavity of A. mississippiensis with all viscera removed. (d) Dorsal view of the gas-exchanging lungs of the African grey parrot (Psittacus erithacus) (no air sacs are shown). (e) Lungs of P. erithacus in association with the vertebral column and dorsal ribs in left anterolateral view. (f) Interior of the thoracic cavity of the ostrich (Struthio camelus) with all viscera removed. Segmented surface models in (a,b,d,e) generated in the visualization programme Avizo 7.1 from microCT DICOM data of inflated lungs in situ. Abbreviation: s, costal sulci. Images not to scale.
