Predator-Prey Covariance with predator aggregative responses

, 2010
The spatial covariance between prey and predator densities is closely related to the rate of encounters, and thus to predation rates. To include the effect of covariance in dynamic predator–prey models it is useful to express the spatial covariance

Reduced size of larvae and small fish linked to warming and reduced prey density

Ecography, EarlyView.
Body size is an integrative trait that has declined across many ecological assemblages in the last decades. Changes in body size of early life stages and small‐bodied fish are driven by complex interactions between size‐dependent mortality, and temperature‐ and food‐dependent growth, and can have consequences for recruitment to the adult stock and food

Disentangling functional spaces: a multidimensional framework for ecology and conservation

Ecography, EarlyView.
Trait‐based ecology often relies on a single functional space, where diverse traits are combined into one multivariate framework. While convenient, this approach risks masking ecological strategies because variance is often dominated by a few traits, such as body size.

Species traits mediate terrestrial mammal density responses to human impacts

Ecography, EarlyView.
Human activities are reshaping ecosystems, but their effects on species population density remain poorly understood. Most studies focus on species presence–absence, thus limiting insight into how anthropogenic pressures affect population density. Emerging evidence suggests that responses of natural populations to human disturbance are highly variable ...

Decoupling environmental suitability from realized recruitment through ontogenetic environmental filtering in a long‐lived Mediterranean palm species

Ecography, EarlyView.
Long‐lived plants facing anthropogenic disturbance often exhibit recruitment failure despite persistent reproductive adults, generating extinction debt masked by longevity. However, whether adult presence reliably reflects environmental suitability for recruitment remains unclear.

Techno‐Economic Assessment of Large‐Scale Renewable Energy Systems: A Case Study in the Gulf Cooperation Council

Energy Science &Engineering, EarlyView.
A consistent 3 GW hybrid solar–wind configuration was assessed across five GCC locations, revealing substantial regional differences in energy yield and economic performance. Saudi Arabia and Oman achieved the highest generation and lowest LCOE, while the systems delivered substantial CO2 emission reductions across the region.
