Nest Predation in the Canarian Houbara Bustard (Chlamydotis undulata fuertaventurae): An Experimental Study Using Artificial Nests

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
We investigated nest predation in the endangered Canarian houbara bustard using 229 artificial nests and camera traps. Ravens were identified as the main predators, and predation rates were influenced by raven density, vegetation cover, stone cover, and road density.

Demography and dispersal influence the relationship between habitat suitability and population density

open access: yesEcography, Volume 2026, Issue 3, March 2026.
A central goal of ecology is to understand spatial patterns of species densities. Habitat suitability estimates from species distribution models (SDMs) could be used to represent species density and overcome the scarcity of density data. However, there is mixed evidence that habitat suitability is a reliable descriptor of density, and it is suggested ...

Social influences on sculpted Romanesque corbels in the eleventh and twelfth centuries

open access: yes, 2012
Sculpted corbels of the Romanesque period are often categorized as obscene or grotesque, and frequently dismissed as medieval humor or an individual artist’s imagination.

Integrating Multiple‐Covariate Distance Sampling and Habitat Modeling to Inform Conservation of the Asian Houbara in Central Iran

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We combined multiple‐covariate distance sampling (MCDS) with habitat modeling to estimate the abundance and habitat associations of the vulnerable Asian houbara (Chlamydotis macqueenii) in central Iran. Line‐transect surveys in spring 2022 yielded an estimated density of 0.53 individuals/km2 (~5293 birds), with nearly identical results from ...

Shear Bearing Capacity Prediction of Steel-Fiber-Reinforced High-Strength Concrete Corbels on Modified Compression Field Theory

open access: yesBuildings
In order to analyze the shear mechanism of the steel-fiber high-strength concrete corbels, a calculation model for the shear bearing capacity of steel-fiber-reinforced high-strength concrete corbels was proposed based on the modified compression field ...

Structural Behavior of Reinforced Concrete Deep Beams: Comparative Analysis of Experimental and Finite Element Methods

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Reinforced concrete (RC) deep beams are increasingly used in structural applications such as offshore platforms, high‐rise buildings, foundations, and nuclear facilities. However, the absence of a universally accepted strut‐and‐tie method (STM) for their design remains a critical challenge.
