Effects of season length and uniparental care efficacy on the evolution of parental care

open access: yesJournal of Animal Ecology, Volume 92, Issue 9, Page 1719-1729, September 2023., 2023
This theoretical study shows that individual (within‐sex) variation of parental care strategies readily evolves, leading to the coexistence of different care patterns in the same population. Depending on season length and uniparental care efficacy, alternative equilibria often exist, explaining variation across populations and the evolutionary lability

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Plant economics traits predict plant carbon allocation and responsiveness to arbuscular mycorrhizal fungi under varying precipitation

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1921-1932, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Most terrestrial plant species form symbioses with arbuscular mycorrhizal fungi (AMF). However, the below‐ground carbon (C) allocation of plants and the nutritional and growth benefits provided by AMF within this symbiosis vary greatly across species and environments ...

Profiling EFL Students’ Motivation and Anxiety in Collaborative Learning: Associations With Teachers’ Support, Self‐Regulated Learning, and Achievement

open access: yesInternational Journal of Applied Linguistics, Volume 36, Issue 2, Page 979-994, May 2026.
ABSTRACT Previous research has established the relationships between motivation, anxiety, teachers’ support, and self‐regulated learning (SRL) in English‐as‐a‐foreign‐language (EFL) learning. Most of the studies, however, have taken a variable‐centered approach in addressing the variable correlations, while learners’ characteristics and variable links ...

The Inclusion Trade‐Off: Comparing the Design and Functionality of Collaborative Governance Forums

open access: yesPolicy Studies Journal, Volume 54, Issue 2, May 2026.
ABSTRACT Environmental challenges require collaboration across jurisdictions, often through forums or intermediary spaces for repeated interaction. A persistent forum design question concerns inclusion criteria, or which actors should be included.

Assessing the Effect of Deservingness Cues on Tolerance for Administrative Burdens

open access: yesPolicy Studies Journal, Volume 54, Issue 1, February 2026.
ABSTRACT Beneficiaries of public programs must overcome several administrative challenges. Given what we know about the politics of the welfare state, it seems likely that the public's willingness to support reductions in burdens may be associated with the characteristics of potential policy targets including their life circumstances and their race ...

四环素类抗菌素碱性降解荧光增敏作用研究 [PDF]

open access: yes, 1997
四环素类抗菌素的碱性溶液(kOH)在沸水浴中加热一定时间而发生降解,其降解物的荧光激发光谱和发射光谱均发生改变,且荧光强度较四环素类抗菌素本身的天然荧光增强5~190倍,认为发生了分子内亲核断环反应,生成具有内酯结构的降解物,此降解物内酯结构中氧原子上孤对电子与共轭π电子相互作用.使分子中共轭电子体系的离域性增大,荧光增强.国家自然科学基金 ...

UV/K2S2O8耦合降解四环素研究

open access: yesGongye shui chuli, 2017
研究了UV/K2S2O8体系对水中四环素的降解效果。首先对比了该反应体系与UV氧化、单独K2S2O8氧化对四环素的处理效果,结果表明UV能有效活化分解K2S2O8,能有效去除水中的四环素。同时探讨了四环素初始浓度、K2S2O8投量、反应时间、溶液初始pH对降解效果的影响,结果表明,在最佳条件下四环素的降解率达100%。同时实验结果表明,UV/K2S2O8体系对四环素的降解过程符合一级动力学规律。最后探讨了UV/K2S2O8技术降解四环素的机理。

Development of a Four‐Language Questionnaire to Investigate Environmental Risk Factors for the Development of Canine Atopic Dermatitis and to Monitor Disease Course and Progression

open access: yesVeterinary Dermatology, Volume 37, Issue 1, Page 34-44, February 2026.
Background: The chronic and multifactorial character of canine atopic dermatitis (cAD) often leads to poor disease control and treatment dissatisfaction. Environmental factors are likely to contribute to the disease development and may play a more important role than assumed previously.

Nitrogen Anchoring Effect Triggering Improved Reversible Hydrogen Storage of Mg(BH4)2

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT This research uncovered the influence of nitrogen‐doped MXene Ti3CN on the reversible hydrogen storage properties of Mg(BH4)2. The Mg(BH4)2‐20Ti3CN composite began releasing hydrogen at a temperature of 80°C. In addition, the composite discharged over 8.8 wt% hydrogen at a comparatively lower temperature of 270°C, whereas the pure Mg(BH4)2 ...
