Symbiotic Germination Technique of an Endangered Epiphytic Orchid Dendrobium sinominutiflorum: A Promising Conservation Application 濒危附生兰科植物勐海石斛 (Dendrobium sinominutiflorum) 的共生萌发技术:一种具有应用前景的保护策略

open access: yesIntegrative Conservation, EarlyView.
We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique. The Symbiotic germination with Tulasnella sp. significantly promotes seed germination and seedling growth.

Land use overrides climatic controls on soil organic nitrogen transformations: Contrasting responsiveness between forest and cropland ecosystems

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil organic nitrogen (SON) transformation is critical for global nutrient cycling and ecosystem productivity, yet how its responsiveness to climate change differs across diverse land use types remains poorly resolved.

Comprehensive framework for assessing and optimizing existing research networks

open access: yesConservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

源荷储多类型灵活性资源协调的高比例可再生能源电源规划 [PDF]

open access: yes全球能源互联网, 2019
未来高比例可再生能源电力系统愿景下,具有波动性和不确定性的风/光等可再生能源作为主要能源供应者,给电力系统带来了巨大的灵活性需求,考虑单一类型灵活性资源提供调节能力的规划模型和以净负荷包络线为基础的电源规划方法将不再适用。引入灵活性指标量化评估源荷储多类型灵活性资源的调节潜力并作为优化决策变量纳入到规划模型中,从而建立以全周期投资成本最小化为目标的高比例可再生能源电源规划模型。通过电源投资决策、生产模拟和灵活性评估3个流程模块,实现单位投资改善灵活性指标最优的电源规划方案求解。最后 ...

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

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

Reconceptualising Motivation as Material‐Semiotic Entanglements: Translanguaging in Graduate TESOL Education

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Multilingual students in Anglophone universities often operate in survival mode. While translanguaging supports learning, critical gaps remain in understanding how translanguaging pedagogies transform and sustain motivation in English‐dominant contexts.

Marketization in Public Purchasing as a Route to Business Corporations' Institutional Power: The Case of Outsourcing Social Services in Israel

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT What are the conditions under which business corporations expand their institutional power? This paper argues that institutional power is affected by the architecture of the “acquisition regime”—the set of formal (and informal) rules that govern how states purchase public services.

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.
