Waves, rivers, and tides shape delta morphology. Recent studies have enabled predictions of their relative influence on deltas globally, but methods and associated uncertainties remain poorly known. Here, we address that gap and show how to quantify delta morphology within the Galloway ternary diagram of river, wave, and tidal sediment fluxes.

Background: The increased emphasis on reimbursement, diversity, and burnout in hip and knee arthroplasty necessitates a foundational understanding of the surgeon workforce. The purpose of the study was to cross sectionally survey a representative sample of the AAHKS surgeon membership on the subject of salary, practice patterns, and demographic factors to establish a baseline framework for future advocacy efforts and initiatives.
Methods: An online survey was sent to AAHKS members between December 20, 2022 and January 19, 2023.

Objective: To describe a method of estimating the carbon emissions resulting from 10 clinical canine surgical procedures.
Study Design: Prospective observational cohort study.
Animals: A total of 10 adult client-owned dogs presenting to two private referral centres in the UK for tibial plateau levelling osteotomy (TPLO) using either isoflurane or sevoflurane for maintenance of anaesthesia.

Hydropower is central to renewable electricity systems, but degrades ecosystems, calling for environmental flow schemes to enhance the ecological status of river systems. Environmental flow assessments need to account for climate change, since climate-driven changes in runoff affect both hydropower operation and riverine ecosystems. Here, we quantify expected changes in hydropower production and environmental benefits of introducing environmental flows in a large regulated river system in northern Sweden in a future climate.

is described from the Qiantang and Oujiang rivers in Zhejiang Province and a tributary of the Yangtze River adjacent to the Qiantang River. It is distinguished from congeners by the following combination of morphological features: no obvious anterior notch on the tip of the upper lip; 45-52 lateral-line scales; 18-21 pre-dorsal scales; two rows of pharyngeal teeth; a maxillary extending to or slightly beyond the vertical anterior margin of the orbit in adult males; a pectoral fin extending to the pelvic fin in adult males; nuptial tubercles on the cheeks and lower jaw of males, which are usually united basally to form a plate; uniform narrow pale pink cross-bars on trunk and two widening significantly on caudal peduncle. Its validity was also supported by its distinct Cyt gene sequence divergence from all congeners and its monophyly recovered in a Cyt gene-based phylogenetic analysis.
