Advancing conservation breeding programs for marine invertebrates

open access: yesConservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Informing elephant management through demographic snapshots

open access: yesConservation Science and Practice, EarlyView.
Understanding demography is vital for managing species successfully; however, for elephants, traditional surveys are both costly and labor‐intensive. This study presents a cost‐effective method for estimating age structures of savannah elephants in southern Africa, revealing how water provisioning, density dependence, and fertility control influence ...

Against the odds: Nesting specialization and foraging ecology provide insights into climate change responses in a mountain bee

open access: yesInsect Conservation and Diversity, EarlyView.
A unique high‐elevation Exoneura bee defies typical elevation‐driven declines in bee activity, nesting exclusively in dead branches of snow gums near the alpine tree line. Nesting and foraging are tightly linked to snow gum presence, with most activity occurring within 30 m of these trees. Biophysical modelling indicates the bee's thermally constrained

Does ulnar curvature covary with locomotion and substrate use in cercopithecids?

open access: yesJournal of Anatomy, EarlyView.
This study investigates ulnar curvature in cercopithecids in relation to locomotor behaviors, introducing an analysis of anteroposterior and mediolateral curvature, using geometric morphometric on 167 specimens (23 species). Although the two curvatures distinguish arboreal and terrestrial quadrupeds, their moderate covariation suggests that they ...

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

open access: yesJournal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Locating regions of interest prior to X-ray imaging using stereo-photogrammetry

open access: yes, 2011
The research project aims at locating regions of interest (ROIs) on human subjects prior to X-ray imaging on the Lodox Statscan whole body imaging ...

Obtaining full‐arch implant scan with smartphone video and deep learning: An in vitro investigation on trueness and precision

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the accuracy of complete‐arch implant scans generated by a smartphone camera and a deep learning model. Materials and Methods A deep learning model was trained to generate 3D scans from smartphone videos using a maxillary edentulous model with 6 implants and scan bodies (SBs).

Effect of angulation between multi‐unit abutments on trueness of photogrammetry systems

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To compare the trueness between conventional impressions (CI) and photogrammetry for full‐arch implant‐supported prosthesis and to evaluate the effect of increased inter‐abutment angulation on trueness. Materials and Methods Three edentulous reference models containing four multiunit abutment (MUA) replicas with different inter ...

Use of open‐source software and photogrammetry in the fabrication of 3D‐printed custom trays for edentulous patients: A technical guide

open access: yesJournal of Prosthodontics, EarlyView.
Abstract A technique is described to obtain a 3D‐printed custom tray for complete dentures through open‐source, free software and additive manufacturing. This approach enables the production of custom trays in a cost‐effective and optimized manner. A three‐dimensional (3D) digital cast is obtained by photogrammetry and later used to design a digital ...
