Leaf C:P ratio as a universal indicator of photosynthesis in subtropical woody species: Stoichiometric thresholds and metabolic trade‐offs

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization.

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

open access: yesConservation Biology, EarlyView.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Drivers of bat researchers’ intent to adopt field hygiene practices

open access: yesConservation Biology, EarlyView.
Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Advancing conservation breeding programs for marine invertebrates

open access: yesConservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Regulatory compliance and support for altered management of the exotic pet trade

open access: yesConservation Biology, EarlyView.
Abstract Globally, the exotic pet trade has contributed to species invasion, disease, and animal welfare risks. Although scientists have advocated for increased trade regulation, the success of management and regulatory efforts depends on compliance by participants in the exotic pet trade. We used a regulatory compliance framework to investigate exotic

Emerging applications of large language models in ecology and conservation science

open access: yesConservation Biology, EarlyView.
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

从应用力学到工程科学

open access: yes, 2020
工程科学起源于20世纪初德国以普朗特为代表的应用力学学派;20世纪30年代应用力学研究中心转移到美国以冯·卡门为代表的古根海姆空气动力学实验室,钱学森先生师从冯·卡门,在这一领域做出了杰出贡献,并明确提出、系统阐述了工程科学的思想。国内外航空、航天工程的实践已经证明,工程科学可以加速科学革命、经济发展、社会进步。未来工程科学研究领域将从自然现象扩展到生命体乃至人文科学,如:工程管理、工程伦理和工程哲学,并引领交叉学科领域的前沿研究。为适应这一发展趋势,我们将通过强基础、阔领域、重实践、促创新 ...
