Reintroduction of an Endangered Butterfly, the Mottled Duskywing (Erynnis martialis)

Animal Conservation, EarlyView.
We reintroduced Mottled Duskywing (Erynnis martialis), an endangered skipper butterfly, at different life‐stages to restored oak savanna habitat in Ontario, Canada and then performed intensive post‐release monitoring. Our results show that, at one of three sites, a population was established within two years of initiating releases and that pupae and ...

Behavior of Long‐Slotted Perforated Steel Plate Fuses in Timber Brace End Connections

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1247-1269, May 2026.
ABSTRACT Steel perforated plate fuses have emerged as a promising solution for mass timber seismic force‐resisting systems, offering tunable energy dissipation mechanisms, such as flexural and shear yielding, through geometric adjustments. This study examines the cyclic performance of perforated steel plate fuses employed in timber braced frames, with ...

Surgical correction of closed simple metatarsal fractures in a pet rabbit (Oryctolagus cuniculus) with intramedullary pins

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract A 4‐month‐old pet rabbit was presented with intermittent left pelvic limb lameness, painful and swollen left metatarsal region. Radiographs revealed complete simple fractures of the left metatarsal bones II, III and IV. Open reduction and internal fixation were performed using intramedullary pins.

A Within Canopy Deposition Model Capturing the Influence of Microplastic Size, Biological Cohesion, and Vegetation‐Generated Turbulence

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Laboratory experiments investigated how the presence of biofilm and particle size influenced deposition in both bare and vegetated channels. Both abiotic and biotic sediment beds were considered, with the biotic beds containing Extracellular Polymeric Substances (EPS). As current magnitude and turbulent kinetic energy increased, particles were

Material and geometric nonlinear analysis of reinforced concrete frame structures considering the influence of shear strength complementary mechanisms

Latin American Journal of Solids and Structures
A mechanical model for the analysis of reinforced concrete frame structures based on the Finite Element Method (FEM) is proposed in this paper. The nonlinear behavior of the steel and concrete is modeled by plasticity and damage models, respectively.
