The role of UV in crab spider signals: effects on perception by prey and predators [PDF]
, 2005 Australian crab spiders Thomisus spectabilis sit on the petals of flowers and ambush prey such as honeybees. White-coloured T. spectabilis reflect in the UV (UV+ spiders) and previous research has shown that their presence, curiously, attracts honeybees ...

Marine silicon for biomedical sustainability
BMEMat, EarlyView.Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

Biological Reviews, EarlyView.ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Shank Color and Barred Plumage in Columbian-Colored Chickens
Poultry Science, 1955 Abstract MANY females produced from crosses of barred columbian, (B S e), males and red, e, females develop a greenish shank coloration by the broiler age of 8 to 12 weeks after hatching. This greenish shank coloration, often designated as “willow,” may vary in incidence from 12 to 80% of the females at the broiler age.

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces
