The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds
Journal of Anatomy, EarlyView.The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Journal of Systematics and Evolution, EarlyView.Our ancestral state reconstruction in tree crickets reveals multiple independent and irreversible losses of sound‐producing and ‐receiving structures, supporting the convergent evolution of the silent phenotype. We demonstrate strong evolutionary integration between forewings and tympana, although the discovery of ‘silent listeners′ and ‘deaf singers ...

WHAT ONCE WAS SHALL BE AGAIN: PALAEOLITHIC BIFACES AT THE NEOLITHIC SITE OF GIV'AT RABI EAST
Oxford Journal of Archaeology, EarlyView.Summary Giv'at Rabi East is a Pre‐Pottery Neolithic B site located in northern Israel, interpreted as a flint workshop. One area has been spatially identified as a ‘biface locality’; it is characterized by the presence of finished axes and preforms alongside débitage. Interestingly, Acheulean bifaces have also been recovered from this area.

Physiological Entomology, EarlyView.Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

Microclimate-Adaptive Morphological Parametric Design of Streets and Alleys in Traditional Villages
BuildingsMicroclimate is a reflection of the climatic conditions within the scope of human daily activities, so it is closely related to human activities. This paper uses Qingshui Village in Hancheng as the research object and the purpose of this paper was to ...

Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs
Physiological Entomology, EarlyView.In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

, 1920 Patent for a toy grasshopper that is able to jump on surfaces once it is set down to simulate the propelled jumping of a grasshopper. Because of its design, primarily of rubber bands and levers, the movement is unique.

Philosophy and Phenomenological Research, EarlyView.ABSTRACT It is widely assumed that all games essentially have rules. This paper challenges this apparent truism. We argue that rules are merely one means for generating obstacles: features that make success more difficult. We propose that obstacles, not rules, are essential to games. This shift comes with several theoretical benefits.
