Is quinoa‐farming sustainable in marginal environments? Social, economical and environmental aspects
Journal of the Science of Food and Agriculture, EarlyView.Abstract Quinoa (Chenopodium quinoa Willd.) is an Andean grain crop introduced as a novel crop to many parts of the world in recent years. Recognized for nutritious seeds and high abiotic stress tolerance, it has been promoted as an element of climate‐resilient agriculture, particularly in marginal environments.

BMC Plant Biology, 2012 Background Plants are sessile and therefore have to perceive and adjust to changes in their environment. The presence of neighbours leads to a competitive situation where resources and space will be limited.

Spatial and temporal variation in survival of female wild turkeys
The Journal of Wildlife Management, EarlyView.We monitored 370 female wild turkeys across North Carolina's 3 ecoregions from 2020‐2022 to understand factors influencing their survival. Female survival varied by ecoregion and behavior state, with the incubation period having the lowest survival rates. None of the land cover variables affected survival.

Natural Selection on Hydroid Colony Morphology by Intraspecific Competition [PDF]
Evolution, 1991 Previous work on colonial hydroids in the genus Hydractinia has demonstrated that colony morphology is highly variable and determines intraspecific competitive ability. Competitive encounters are known to be common in nature, suggesting that intraspecific competition may be a major selective force acting on morphological variation.

Density‐dependent habitat selection in plains bison
The Journal of Wildlife Management, EarlyView.Using GPS collar data, we tested whether habitat selection of plains bison in Grasslands National Park, Canada, was density dependent. Bison selected for areas of high vegetation productivity far from human activity when population density was low and increased use of lower productivity habitat closer to disturbance as density increased.

Chemical Competition between Microscopic Stages of Macrocystis pyrifera and Five Native Kelp Species: Does Giant Kelp Always Lose? [PDF]
, 2018 The giant kelp Macrocystis pyrifera is often considered competitively dominant to other kelp species due to its high productivity. However, on the microscopic level, previous studies found that Macrocystis can be inferior to other kelp species through ...

Response of specific leaf area to light: comparative study of a large species set
Oikos, EarlyView.Specific leaf area (SLA) is a commonly used proxy for the leaf economy spectrum in plants, separating species with low‐cost leaves (in terms of carbon) with short lifespan and hence fast turnover from species with high‐cost and long‐lived leaves. While SLA is used mainly for interspecific comparisons, it also varies within species both ontogenetically ...
