Modelling invasion potential of Bighead Carp under climate change: effects of seasonal temperatures on a recruitment bottleneckNARA Subscribed
Because young-of-year (YOY; age-0) are vulnerable to overwinter mortality, fishes invading higher latitudes could encounter colder conditions that impose population bottlenecks, but warming under climate change could reduce such restrictions. To examine how populations might respond to anticipated warming and whether they could establish, we developed a life-history model, integrating four published empirical relationships (da...
Preservation of plant‐wax biomarkers in deserts: implications for Quaternary environment and human evolutionary studiesNARA Subscribed
Analysis of plant‐wax biomarkers from sedimentary sequences can enable past environmental and hydrological reconstruction and provide insights into past hominin adaptations. However, biomarker preservation in desert contexts has been considered unlikely given the sparse nature of the vegetation within the landscape. Here we evaluate the preservation of n ‐alkanes and fatty acids collected from four depositional sequences assoc...
Non-linear effects on the population performance of Bighead Carp under different maturation schedulesNARA Subscribed
Bighead Carp currently threatens to invade the Laurentian Great Lakes from the Mississippi River, but the novel climatic conditions it will encounter by expanding northwards could affect its population performance. Bighead Carp in colder climates exhibits slower growth and matures later, with later maturation typically leading to larger adult size and increased fecundity and survival. Accordingly, the life-history strategies o...
The global abundance of tree palmsNARA Subscribed
Aim Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms are evolutionarily, morphologically and physiologically distinct from other trees, and these differences have important consequences for ecosystem services (e.g., carbon sequestration and storage) and in terms of responses to climate change. We quantified global patterns of tree...
A primary goal of ecosystem‐based fishery management is to reduce non‐target stock impacts, such as incidental harvest, during targeted fisheries. Quantifying incidental harvest has generally incorporated fishery‐dependent catch data, yet such data may be biased by gear non‐retention, observation difficulties, and non‐random harvest patterns that collectively lead to an impartial understanding of non‐target stock capture. To a...
