Although their remains have been known since the 1870s, the small, bipedal ornithischian dinosaurs from the Upper Jurassic Morrison Formation of the western USA remain poorly known. The historic type specimens are incomplete and poorly preserved and have

Monitoring and Research on Wading Birds in the Water Conservation Areas ofthe Everglades: The 1996 Nesting season [PDF]
This project was initiated to continue monitoring reproductive responses of wading birds in the central Everglades, and to investigate two areas of research considered key to understanding and managing wading birds: nestling energetics, and factors ...

This study performs pan‐viromic profiling of 14,529 samples from 5,710 domestic herbivores across five Chinese provinces, establishing the DhCN‐Virome (1,085,360 viral metagenomes). It reveals species/sample‐specific viromic signatures and cross‐species transmission dynamics, aiding unified disease control.

The First Anti Poison Dog Unit in Bulgaria to Secure the Eagle and Vulture Populations Persistence
Poisons in ecological systems pose threat to a number of mammal and bird species at global scale (Zugasti, 2014, Brochet et al., 2017). This is recognized as the most severe threat to all vulture species worldwide (Botha et al., 2017) and at the same ...

Occurrence of Fungi on Duck Egg Shells and Drug Resistance Analysis of Aspergillus spp. Isolates
Fungi are a typical part of the microbiome of poultry houses, but some of the genera can be pathogenic for poultry and humans. An investigation was conducted on 200 duck eggs from 10 flocks to determine total fungal contamination on the eggshells.

Influence of rearing environment on development of perching and dustbathing behaviour in laying hens [PDF]
Studies have shown that perching and dustbathing behaviour in birds can be affected by how and when the behaviour develops. With the increasing trend away from cages and towards keeping laying hens in larger, more complex housing systems, it is important

Perspective: Hollow Core Optical Fibres for Ultraviolet and Visible Wavelengths
Hollow core optical fibres bypass material constraints that limit optical fibres at ultraviolet and visible wavelengths. However, their challenging fabrication has limited their development, and significant gains in performance remain possible. In this perspective we outline approaches to enable the next generation of fibres for shorter wavelengths ...

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.
