Coexisting ant species differ in ability to meet their intrinsic nutritional needs

Oikos, EarlyView.
Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

Measures of Prices and Price Competitiveness in International Trade in Manufactured Goods [PDF]

The purpose of this paper is to present, and to explain the construction of, a set of price indexes relating to international trade in manufactured goods. These include: 1. Indexes of export prices for the U.S., Germany, and Japan, based on their weights,

Trait‐mediated thermal responses and multi‐axis spatiotemporal niche partitioning between coexisting top predators in ponds

Oikos, EarlyView.
Understanding how physiological constraints scale up to realized niche differences remains a central challenge in functional ecology. Temperature strongly influences metabolic performance, activity, and habitat selection in ectotherms, yet few field studies quantify how thermal responses interact with diel and habitat structure to shape predator ...

Do good neighbours compensate for bad climate? The case of sessile oak Quercus petraea in phylogenetically distant neighbourhoods

Oikos, EarlyView.
Stressful climates threaten the performance of individuals and the survival of species, but individual performance also depends on biotic interactions with neighbours, so that ‘good' neighbours might in theory compensate for ‘bad' climates. However, what makes a good neighbour, and why, has been little studied.

Is there a Difference? The Performance Characteristics of SRI Equity Indexes [PDF]

Investments in socially responsible investments (SRI) are still a small, but growing segment of international capital markets. This study analyses whether a SRI screening process applied to equities results in a different performance outcome compared to ...

Breeding for multi‐stress resilience in crops: Myth or possibility?

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change threatens millions of farmers worldwide by exposing crops to multiple concurrent or sequential environmental stresses such as drought, heat, waterlogging, and diseases. Although crops have long been selected under naturally occurring multi‐stress conditions, breeding pipelines largely focus on optimal or single‐stress environments ...
