Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Seasonal variation and implications of the concentration of different phosphorus species and phosphate oxygen isotope composition in Jiulong River estuary [PDF]
, 2015 磷是生物生长所必须的营养元素，在天然水体环境中，磷的浓度比较低，可能会限制生物的生长。而若环境中的磷浓度过高，就会造成富营养化，甚至引发赤潮。磷在自然界中一般以磷酸盐的形式存在，主要分为溶解态磷和颗粒态磷，溶解态磷分为溶解无机磷和溶解有机磷，颗粒态磷又分为颗粒无机磷和颗粒有机磷。 磷是一种颗粒活性元素，它只有一种稳定同位素（31P），因此无法利用稳定同位素技术研究磷循环。研究发现磷酸盐氧同位素在生物或酶的作用下会与水发生氧交换，而非生物作用磷酸盐和水间不会发生氧交换。因此一些研究用磷酸盐氧同位素 ...

Conservation Biology, EarlyView.Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.

Seasonal and intra-seasonal dynamics of sea surface pCO2 on the mid-shelf of the East China Sea: buoy-based time series observations [PDF]
, 2015 近岸水体在全球海洋碳循环中扮演重要角色，但由于其地处海陆交界以及受人为活动的扰动，近岸水体的碳循环过程复杂且多变，这种复杂的变化过程也反映在海水二氧化碳分压（pCO2）随时间的剧烈波动上。鉴于近岸水体海表pCO2的时间变异性，特别需要长期高频的时间序列观测，以甄别其在不同时间尺度的变化规律和调控机制，并且为一些难以通过船载观测捕捉到的短期剧烈变化事件（如台风）提供研究的机会。 本研究主要基于浮标观测，该浮标观测点位于东海中部陆架（124.5°E31°N），水深约60m ...

Veterinary Dermatology, Volume 37, Issue 2, Page 293-305, April 2026.Background: Canine atopic dermatitis (cAD) is a common, chronic skin condition characterised by epidermal barrier dysfunction, immune dysregulation and cutaneous dysbiosis. While “emollient plus” formulations are widely used in human atopic dermatitis, their role in cAD remains underexplored. Hypothesis/Objectives: To evaluate the clinical efficacy and

Ecology and Evolution, Volume 15, Issue 10, October 2025.This paper proposes a ‘relaxed’ point‐count survey method to enhance accessibility and expand geographic coverage by easing these constraints. Surveys can be conducted in diverse locations, including urban areas and travel routes, within flexible timeframes (e.g., 6 h after sunrise or during the evening) and with adaptable spacing between survey points,

, 2009 荒漠对气候变化具有高度敏感性,深刻认识和量化非生物因子对荒漠生态系统土壤呼吸的影响具有重要意义。采用自动CO2通量系统(Li-8100)监测了梭梭(Haloxylon ammodendron)、假木贼(Anabasis aphylla)和盐穗木(Halostachys caspica)群落生长季土壤呼吸及温度、土壤含水量等,深入分析了水热因子对土壤呼吸的影响。土壤呼吸具有不对称的日格局,最小值出现在8:00,最大值在12:00～14:00。土壤呼吸的季节格局与气温变化基本同步,最小值在生长季末期(10月)

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the

On the normative roles of biodiversity and naturalness in conservation
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Nature is an opaque concept. Consequently, the term biodiversity conservation has replaced nature conservation in most conservation contexts. We review the conceptual indeterminacies that plague the terms nature and natural but then show that comparable difficulties plague biodiversity.
