Individual variation in perceived density of conspecifics and its impacts on the realization of ecological niches

Oikos, Volume 2026, Issue 5, May 2026.
Animals gather information about their surroundings, including their social environment, using a wide range of sensory modalities. Variation in reception, processing and interpretation of information (cues or signals) can lead to differences in how individuals perceive their local environment. Yet, how individual differences in environmental perception

Effects of Joint Configurations on Shear Behavior of Prefabricated Segmental Cap Beams

Buildings
The joint configurations of prefabricated segmental cap beams exhibit considerable diversity in engineering applications. In recent years, combined shear key corbel connections have been increasingly adopted due to their advantages in prefabrication ...

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

Ecological 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

Ecography, 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 ...

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

Ecology 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 ...

A MODIFIED FORMULA TO PREDICT THE ULTIMATE LOAD CAPACITY OF REINFORCED CONCRETE CORBELS

Journal of Engineering and Sustainable Development, 2019
Various methods are used in designing reinforced concrete corbels. The aim of the present research is to provide a modified formula to predict the ultimate strength of reinforced concrete corbels using nonlinear regression analysis of experimental data ...

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

Advances 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.

A Calculation Method for the Shear Strength of Steel Fiber-Reinforced High-Strength Concrete Corbels Based on the Softened Strut-and-Tie Model

Buildings
To investigate the shear performance of steel fiber-reinforced high-strength concrete (SFRHSC) corbels subjected to concentrated loading, an experimental program was executed on six specimens featuring welded anchorage for the upper longitudinal ...

L’imaginaire utopique dans la Comédie ancienne, entre eutopie et dystopie (l’exemple des Oiseaux d’Aristophane)

Kentron, 2010
The aim of this paper is to study the mechanism of utopia in Aristophanes’ Birds. This comedy reveals a number of formal patterns typical of utopian fantasy such as the journey to faraway countries, the restoration of a golden age,
