Aims Potassium (K) nutrition is essential in grasslands, but soil K buffering capacity is highly soil-specific, making generic fertiliser recommendations challenging. Highly K-buffered soils have a greater capacity to store and resupply exchangeable K, often resulting in minimal observable changes in soil test K (STK) in response to applications of mineral fertiliser K (MNK). Conversely, low K-buffered soils typically show gre...

Lettuce is a cool-season leafy green commonly grown in hydroponics. Romaine lettuce is economically expensive, yet it has more desirable health benefits and market demand than other lettuce types. However, high electrical conductivity (> 2.0 dS m −1 ) of water impacts nutrient supply and growth, thus affecting its economic viability. Despite negative impact of salt stress on hydroponically grown lettuce, its effects on the pla...

Aim The role of ecological specialisation in shaping biogeographic and evolutionary patterns remains unresolved. To date, few studies have quantitatively examined consumer niche breadth at a global scale. We describe global biogeographic and diversification patterns of specialisation, measured using trophic and thermal niches, for a highly diverse assemblage of consumers: reef fishes. First, we investigated the confluence of s...

Harbor seal ( Phoca vitulina ) numbers in the United States rebounded after the implementation of conservation measures associated with the Marine Mammal Protection Act of 1972 (MMPA). Stock estimates are a critical tool for assessing species status and management options under the MMPA and for modeling efforts designed to evaluate the role of pinnipeds in marine ecosystems. We conducted aerial surveys of harbor seal haul‐out...

Increase of collagen content and reorganization characterizes fibrosis but quantifying the latter remains challenging. Spatially complex structures are often analyzed via the fractal dimension; however, established methods for calculating this quantity either provide a single dimension for an entire object or a spatially distributed dimension that only considers binary images. These neglect valuable information related to coll...

Understanding how human infrastructure and other landscape attributes affect genetic differentiation in animals is an important step for identifying and maintaining dispersal corridors for these species. We built upon recent advances in the field of landscape genetics by using an individual‐based and multiscale approach to predict landscape‐level genetic connectivity for grizzly bears ( Ursus arctos ) across ~100,000 km 2 in C...

Data capturing multiple axes of tree size and shape, such as a tree's stem diameter, height and crown size, underpin a wide range of ecological research—from developing and testing theory on forest structure and dynamics, to estimating forest carbon stocks and their uncertainties, and integrating remote sensing imagery into forest monitoring programmes. However, these data can be surprisingly hard to come by, particularly for...
