Accuracy of Short-Interval Trap-Nesting of the Fowl

open access: yesPoultry Science, 1941
Abstract DAILY trap-nesting of fowls is one of the most costly operations of a poultry breeding plant. Any reduction in the labor required in obtaining trap-nest records would obviously reduce the costs of operation. Many short-cut methods for obtaining satisfactory egg records of hens have been proposed and a complete review of the literature was ...

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

open access: yesAdvanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

open access: yesAngewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

open access: yesAdvanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

A Nest Trap for Snowy Plovers [PDF]

open access: yes, 2000
A nest trap designed for ground nesting birds, specifically Snowy Plovers (Charadrius alexandrinus), is described. The trap is inexpensive to construct, easy to operate, and lightweight for ease of use under field conditions.

Senolytic Therapy as a Preventive Strategy for Spine Degeneration and Pain

open access: yesAdvanced Science, EarlyView.
Cellular senescence promotes inflammation, tissue degeneration, and chronic back pain. In sparc‐null mice, early oral administration of the senolytic agents o‐vanillin and RG‐7112 reduced senescent cell burden and pro‐inflammatory SASP signaling across intervertebral discs, endplates, vertebral bone, and spinal cord.

Trap nests for bees and wasps to analyse trophic interactions in changing environments—A systematic overview and user guide

open access: yesMethods in Ecology and Evolution, 2018
Trap nests are artificially made nesting resources for solitary cavity‐nesting bees and wasps and allow easy quantification of multiple trophic interactions between bees, wasps, their food objects and natural enemies. We synthesized all trap nest studies

Effect of Feathers as Nest Insulation on Incubation Behavior and Reproductive Performance of Tree Swallows (\u3cem\u3eTachycineta bicolor\u3c/em\u3e) [PDF]

open access: yes, 1995
Many species of birds line their nests with feathers, presumably because of the insulative qualities of feathers and because feathers may act as a barrier between nest parasites and nestlings.
