    地球同时面临生物多样性和气候危机。气候变化避难所-受气候变化相对缓冲的地区-可以通过在周围景观不再能够维持生物多样性的组成部分来帮助解决这两个问题。然而,这种支持生物多样性的能力往往容易受到严重的气候变化和其他压力因素的影响。因此,管理行动需要考虑避难所的复杂性和多维性。我们概述了一种方法来了解避难所促进过程并评估避难所能力以确定合适的管理措施。我们的框架将气候变化避难所作为工具,以促进现代保护规划中的阻力。这种以避难所为重点的管理可以减少物种灭绝,并在气候变化下保持生物多样性。
    Earth is facing simultaneous biodiversity and climate crises. Climate-change refugia - areas that are relatively buffered from climate change - can help address both of these problems by maintaining biodiversity components when the surrounding landscape no longer can. However, this capacity to support biodiversity is often vulnerable to severe climate change and other stressors. Thus, management actions need to consider the complex and multidimensional nature of refugia. We outline an approach to understand refugia-promoting processes and to evaluate refugial capacity to determine suitable management actions. Our framework applies climate-change refugia as tools to facilitate resistance in modern conservation planning. Such refugia-focused management can reduce extinctions and maintain biodiversity under climate change.

    人为干扰正在导致广泛的,野生动物分布和密度的全球变化。这些对野生动物的人为影响来自多个自下而上和自上而下的途径,包括栖息地的丧失,资源调配,气候变化,污染,基础设施建设,狩猎和我们的直接存在。动物行为是将这些干扰与种群结果联系起来的重要机制,尽管这些行为途径通常很复杂,并且在相互隔离研究行为的不同方面时可能仍然模糊。空间-社会界面提供了一个镜头,用于理解动物的空间和社会环境如何相互作用,以确定其空间和社会表型(即个体的可测量特征),以及这些表型如何相互作用和反馈来重塑环境。这里,我们在空间-社会界面上回顾动物行为的研究,以理解和预测人类干扰如何影响动物运动,分布和种内相互作用,对人口和生态系统的保护产生了影响。通过了解将人类干扰与保护结果联系起来的空间社会机制,我们可以更好地设计管理干预措施,以减轻干扰的不良后果。本文是主题问题“空间-社会界面:理论和实证整合”的一部分。
    Human disturbance is contributing to widespread, global changes in the distributions and densities of wild animals. These anthropogenic impacts on wildlife arise from multiple bottom-up and top-down pathways, including habitat loss, resource provisioning, climate change, pollution, infrastructure development, hunting and our direct presence. Animal behaviour is an important mechanism linking these disturbances to population outcomes, although these behavioural pathways are often complex and can remain obscured when different aspects of behaviour are studied in isolation from one another. The spatial-social interface provides a lens for understanding how an animal\'s spatial and social environments interact to determine its spatial and social phenotype (i.e. measurable characteristics of an individual), and how these phenotypes interact and feed back to reshape environments. Here, we review studies of animal behaviour at the spatial-social interface to understand and predict how human disturbance affects animal movement, distribution and intraspecific interactions, with consequences for the conservation of populations and ecosystems. By understanding the spatial-social mechanisms linking human disturbance to conservation outcomes, we can better design management interventions to mitigate undesired consequences of disturbance.This article is part of the theme issue \'The spatial-social interface: a theoretical and empirical integration\'.

    血液喂养,这是大多数雌性蚊子繁殖所必需的,提供了病原体传播的机会。采血受光照等外部因素的影响,温度,湿度以及种内和种间相互作用。生理学上,采血周期与营养条件有关,并受保守的激素信号通路控制,这些信号通路使蚊子感觉系统能够定位和评估宿主.人类活动还通过杀虫剂使用等选择压力改变蚊子的采血行为,栖息地和生态系统的改变,和气候变化。值得注意的是,在蚊子的寿命内,采血行为会发生变化,从流行病学的角度来看,这是一个开发不足的现象。对文献的回顾表明,我们对蚊子生物学和采血行为的理解主要基于对少数主要热带物种的研究。这种关注可能会扭曲我们对采血行为关键驱动因素多样性的理解,特别是在苛刻条件的约束下。我们发现证据表明,在血液喂养方面具有显着的适应性,并且在宿主使用决定因素方面存在显着的知识差距。具体来说,流行病学分析假设宿主的使用受到外部因素的影响,而忽视内部生理学。整合所有重要因素对于在快速变化的世界中开发有效的蚊媒疾病传播模型至关重要。
    Blood-feeding, which is necessary for most female mosquitoes to reproduce, provides an opportunity for pathogen transmission. Blood-feeding is influenced by external factors such as light, temperature, humidity and intra- and inter-specific interactions. Physiologically, blood-feeding cycles are linked to nutritional conditions and governed by conserved hormonal signalling pathways that prepare mosquito sensory systems to locate and evaluate hosts. Human activities also alter mosquito blood-feeding behaviour through selection pressures such as insecticide usage, habitat and ecosystem alterations, and climate change. Notably, blood-feeding behaviour changes within a mosquito\'s lifespan, an underexplored phenomenon from an epidemiological standpoint. A review of the literature indicates that our understanding of mosquito biology and blood-feeding behaviour is predominantly based on studies of a handful of primarily tropical species. This focus likely skews our comprehension of the diversity of critical drivers of blood-feeding behaviour, especially under constraints imposed by harsh conditions. We found evidence of remarkable adaptability in blood-feeding and significant knowledge gaps regarding the determinants of host use. Specifically, epidemiological analyses assume host use is modified by external factors, while neglecting internal physiology. Integrating all significant factors is essential for developing effective models of mosquito-borne disease transmission in a rapidly changing world.

    本文试图重新评估从沉积学到地层学的传统地质分类以及全新世/人类世时代的概念,在塑料广泛融入沉积环境的推动下。本文提出了一系列有关合成材料与自然地质过程之间相互作用的新颖见解。我们说明了塑料如何不仅破坏沉积动力学并改变岩石和土壤的成分,造成新形式的污染,但也通过改变侵蚀对海洋生物多样性构成升级的威胁,运输,和沉积模式。我们强调塑料作为独特的地层标志的新兴作用,为人类环境影响提供不同的视角。这种分析挑战了传统的岩石纯粹是自然的看法,无机地层,并强调了融合地质学的跨学科方法的迫切需要,化学,和环境科学。该文件呼吁加强研究,以制定有效的战略来管理这些影响,促进解决塑料污染症状和来源的创新保护技术。
    This paper attempts to reevaluate traditional geological classifications from sedimentology to stratigraphy as well as the concept of the Holocene/Anthropocene epochs, characterized by the widespread integration of plastics into sedimentary environments. This paper presents a set of novel insights into the interactions between synthetic materials and natural geological processes. We illustrate how plastics not only disrupt sedimentary dynamics and alter the composition of rocks and soils, creating new forms of pollution and also pose escalated threats to marine biodiversity through altered erosion, transport, and deposition patterns. We highlight the emerging role of plastics as distinctive stratigraphic markers, providing a different perspective on human environmental impacts. This analysis challenges the traditional perception of rocks as solely natural, inorganic formations and highlights the critical need for interdisciplinary approaches that meld geology, chemistry, and environmental science. The document calls for intensified research to develop effective strategies for managing these impacts and promotes innovative conservation techniques that address both the symptoms and sources of plastic pollution.

    人类世推动了一个变革性的时代,人类活动对地球的生物圈产生了前所未有的影响。因此,同食生物,善于在人为改变的环境中茁壮成长,出现了。虽然在陆地生态系统中进行了很好的研究,在水生生态系统中存在和生态重要性,特别是在蓝细菌中,不太了解。蓝细菌水华,因其对生态系统和人类健康的有害影响而臭名昭著,在全球范围内频率和强度都在增加。从这个角度来看,我们探索支持蓝藻水华上升的证据,强调人类引起的富营养化和气候变化对某些蓝藻属的作用。蓝细菌不是一个整体,某些属在人为改变的环境中显示出可观察到的增加。我们建议建立一个新的植物学分支,该分支明确研究了同食蓝细菌的生态学和生理学。了解同人类物种和人类种群之间复杂的相互作用对于管理人类改变的生态系统和保护淡水资源至关重要。特别是在全球水资源不安全的情况下。实践要点:蓝藻水华的增加是由一小部分适应人类的同人系蓝藻引起的。需要研究来表征向食蓝细菌,这将有助于开发量身定制的管理方法。从驯化到“野化”景观的范式转变以及修改行为以促进同居是降低风险的解决方案。
    The Anthropocene has driven a transformative era where human activities exert unprecedented influence on Earth\'s biosphere. Consequently, synanthropic organisms, adept at thriving in human-modified environments, have emerged. While well studied in terrestrial ecosystems, the presence and ecological importance of synanthropic species in aquatic ecosystems, specifically among cyanobacteria, are less understood. Cyanobacteria blooms, notorious for their detrimental effects on ecosystems and human health, are increasing in frequency and intensity globally. In this perspective, we explore the evidence supporting this rise of cyanobacteria blooms, emphasizing the roles of human-induced eutrophication and climate change on select cyanobacteria genera. Cyanobacteria are not a monolith, with certain genera showing an observable increase within anthropogenically modified environments. We propose the establishment of a new sub-branch of phycology that explicitly investigates the ecology and physiology of synanthropic cyanobacteria. Understanding the intricate interactions between synanthropic species and human populations is imperative for managing human-altered ecosystems and conserving freshwater resources, particularly in the face of increasing global water insecurity. PRACTITIONER POINTS: The rise in cyanobacteria blooms is driven by a small subset of human-adapted genera-synanthropic cyanobacteria. Research is needed to characterize synanthropic cyanobacteria, which will aid in developing tailored management approaches. A paradigm shift from domesticating to \"rewilding\" landscapes and modifying behaviors to facilitate cohabitation are solutions to reducing risks.

    受栖息地丧失和碎片化的驱动,大型食肉动物越来越多地在人类主导的景观中航行,他们的活动受到限制,行为改变。这个运动,然而,对居住在附近的人们提出了重大的担忧和成本。虽然错综复杂,研究经常隔离人类和食肉动物的影响,阻碍有效的管理努力。因此,在这项研究中,我们把这两个纳入一个共同的框架,重点关注印度中部保护区的关键老虎栖息地与人类主导的多用途缓冲区之间的界面区域。
    我们采用了精细比例的相机陷阱调查,并辅以GPS项圈运动数据,以了解时空活动模式和老虎响应人为压力的调整。我们使用了占用框架来评估空间使用情况,贝叶斯循环GLM对时间活动进行建模,以及家庭范围和步长分析,以评估老虎的运动模式。Further,我们使用捕食-风险模型将冲突模式理解为老虎存在和其他栖息地变量的函数.
    尽管受到干扰,大部分采样面积被17只独特的老虎占据(Φ=0.76;CI[0.73-0.92])。到村庄的距离(β±SE=0.63±0.21)和大型野生猎物的相对丰度(β±SE=0.72±0.37)成为老虎空间使用概率的关键预测因子,表明老虎对野生猎物的偏好,而人类的影响限制了他们的栖息地利用。到村庄的距离也被确定为老虎时间活动的最重要预测因子(μ±σ=3.03±0.06rad),在村庄附近表现出较高的夜空率。总共有11%的老虎家范围在村庄边界内,伴随着这些地区更快的运动(位移增加40-82%)。随着靠近村庄(P=0.002)和高速公路(P=0.003),老虎掠夺牲畜的概率增加。尽管老虎空间使用概率(P=0.056)和野生猎物丰度(P=0.134)在0.05阈值处不显著,它们在最适合的捕食风险模型中的存在表明了它们与理解冲突风险的背景相关性.结果强调了适当管理人类基础设施附近的牲畜以有效缓解冲突的重要性。
    食肉动物和人类的共享空间需要以循证决策为基础的动态特定地点行动。这项研究强调了同时解决人类和大型食肉动物之间复杂相互作用的重要性,特别是后者的行为适应和在冲突动态中的作用。这种综合方法对于解开因果关系并促进以人为主导的景观中的有效界面管理至关重要。
    UNASSIGNED: Driven by habitat loss and fragmentation, large carnivores are increasingly navigating human-dominated landscapes, where their activity is restricted and their behaviour altered. This movement, however, raises significant concerns and costs for people living nearby. While intricately linked, studies often isolate human and carnivore impacts, hindering effective management efforts. Hence, in this study, we brought these two into a common framework, focusing on an interface area between the critical tiger habitat and the human-dominated multiple-use buffer area of a central Indian protected area.
    UNASSIGNED: We employed a fine-scale camera trap survey complemented by GPS-collar movement data to understand spatio-temporal activity patterns and adjustments of tigers in response to anthropogenic pressures. We used an occupancy framework to evaluate space use, Bayesian circular GLMs to model temporal activity, and home range and step length analyses to assess the movement patterns of tigers. Further, we used predation-risk models to understand conflict patterns as a function of tiger presence and other habitat variables.
    UNASSIGNED: Despite disturbance, a high proportion of the sampled area was occupied by 17 unique tigers (ψ = 0.76; CI [0.73-0.92]). The distance to villages (β ± SE = 0.63 ± 0.21) and the relative abundance of large-bodied wild prey (β ± SE = 0.72 ± 0.37) emerged as key predictors of tiger space use probability, indicating a preference for wild prey by tigers, while human influences constrained their habitat utilisation. Distance to villages was also identified as the most significant predictor of the tigers\' temporal activity (μ ± σ = 3.03 ± 0.06 rad) that exhibited higher nocturnality near villages. A total of 11% of tiger home ranges were within village boundaries, accompanied by faster movement in these areas (displacement 40-82% higher). Livestock depredation probability by tigers increased with proximity to villages (P = 0.002) and highway (P = 0.003). Although tiger space use probability (P = 0.056) and wild prey abundance (P = 0.134) were non-significant at the 0.05 threshold, their presence in the best-fit predation-risk model suggests their contextual relevance for understanding conflict risk. The results highlight the importance of appropriately managing livestock near human infrastructures to effectively mitigate conflict.
    UNASSIGNED: Shared space of carnivores and humans requires dynamic site-specific actions grounded in evidence-based decision-making. This study emphasises the importance of concurrently addressing the intricate interactions between humans and large carnivores, particularly the latter\'s behavioural adaptations and role in conflict dynamics. Such an integrated approach is essential to unravel cause-effect relationships and promote effective interface management in human-dominated landscapes.

    河口,重要的沿海生态系统,面临工业化日益增长的威胁。为了了解韩国人为改变和工业化的Nakdong河口的沉积变化和重金属污染的速度,我们利用沉积物取芯来重建环境变化。1934年的河口大坝建设将沉积系统从沙子转变为泥浆,与1930年代后由于燃煤而导致的汞增加相吻合。韩国其他地区的汞浓度在1970年代激增,表明与排放源的接近程度。然而,大多数重金属水平(铜,Cd,Zn,Ag)在1960年代和1970年代随着区域工业化而急剧上升。现代重金属浓度是工业化前水平的两倍,强调人类活动是Nakdong河口环境变化的主要驱动力。这强调需要对发展和环境保护采取平衡的方法。
    Estuaries, vital coastal ecosystems, face growing threats from industrialization. To understand the pace of sedimentary changes and heavy metal pollution at the anthropogenically altered and industrialized Nakdong River Estuary in South Korea, we used sediment coring to reconstruct environmental change. Estuarine dam construction in 1934 shifted the sedimentary system from sand to mud, coinciding with a post-1930s mercury increase due to coal burning. Mercury concentrations in other South Korean regions surged in the 1970s, indicating proximity to emission sources matters. However, most heavy metal levels (Cu, Cd, Zn, Ag) sharply rose in the 1960s and 1970s with regional industrialization. Modern heavy metal concentrations doubled pre-industrial levels, underscoring human activities as the primary driver of Nakdong Estuary environmental changes. This emphasizes the need for a balanced approach to development and environmental preservation.

    塑料污染现在在环境中无处不在,对野生动物的威胁越来越大,谁会把塑料误认为食物并摄入它。解决这个问题需要可靠,监测海鸟和其他海洋动物摄入的塑料污染的一致方法,包括识别不同类型塑料的方法。本研究提出了一种快速,使用红外和拉曼光谱对1-50mm尺寸范围内的摄入塑料进行可靠的化学表征。我们分析了来自豪勋爵岛的肉体足剪力机(Ardennacarneipes)摄入的246个物体,澳大利亚,并比较了每种技术产生的数据:通过光谱学确认了92%的摄入物体在视觉上被识别为塑料,其中98%是低密度聚合物,如聚乙烯,聚丙烯,或它们的共聚物。与其他报告相比,摄入的塑料显示出生物污染的重要光谱证据,这阻碍了传统图书馆搜索的识别。机器学习可用于通过振动光谱识别摄入的塑料,准确率高达93%。总的来说,我们发现红外线是识别这个尺寸范围内摄入的塑料的更有效的技术,并且适当训练的机器学习模型可以优于用于识别塑料的常规库搜索方法。
    Plastic pollution is now ubiquitous in the environment and represents a growing threat to wildlife, who can mistake plastic for food and ingest it. Tackling this problem requires reliable, consistent methods for monitoring plastic pollution ingested by seabirds and other marine fauna, including methods for identifying different types of plastic. This study presents a robust method for the rapid, reliable chemical characterisation of ingested plastics in the 1-50 mm size range using infrared and Raman spectroscopy. We analysed 246 objects ingested by Flesh-footed Shearwaters (Ardenna carneipes) from Lord Howe Island, Australia, and compared the data yielded by each technique: 92 % of ingested objects visually identified as plastic were confirmed by spectroscopy, 98 % of those were low density polymers such as polyethylene, polypropylene, or their copolymers. Ingested plastics exhibit significant spectral evidence of biological contamination compared to other reports, which hinders identification by conventional library searching. Machine learning can be used to identify ingested plastics by their vibrational spectra with up to 93 % accuracy. Overall, we find that infrared is the more effective technique for identifying ingested plastics in this size range, and that appropriately trained machine learning models can be superior to conventional library searching methods for identifying plastics.
