ABSTRACT The main driver of biodiversity loss and subsequent decreases in ecosystem functionality is undeniably human interference, destruction and encroachment. The creation and establishment of protected areas serve as tools for guaranteeing biodiversity conservation. In this study, we examined the diversity of medium- and large-sized mammals and flightless walking birds that are supported by a protected area system, the Ischigualasto–Talampaya system, and its area of influence. We set up 106 camera traps and analysed all data with rank–abundance curves and Hill numbers as a measure of diversity. Species richness was lower in protected areas, unlike in the buffer zone, due to the absence of domestic species. Native species were present all over the area, but with variations in their abundances, showing that the presence of domestic species in low densities would not negatively affect the richness of native species, but would indeed affect their abundance.
摘要生物多样性丧失和随后生态系统功能下降的主要驱动因素无疑是人类的干扰、破坏和侵占。建立和建立保护区是保障生物多样性保护的工具。在这项研究中,我们检查了受保护区系统Ischigualasto–Talampaya系统及其影响区域支持的中型和大型哺乳动物和不会飞的鸟类的多样性。我们设置了106个相机陷阱,并用秩-丰度曲线和Hill数分析了所有数据,作为多样性的衡量标准。与缓冲区不同,由于没有国内物种,保护区的物种丰富度较低。本地物种遍布该地区,但其丰度存在差异,这表明低密度的本地物种的存在不会对本地物种的丰富度产生负面影响,但确实会影响其丰度。

ABSTRACT The downstream migration of young-of-the-year (YoY) of four sturgeon species (Acipenser ruthenus, A. stellatus, A. gueldenstaedtii and Huso huso) was monitored in the Danube at river km 396 in 8 continuous years (2014–2021). A total of 713 YoY specimens were registered for the whole period. The most frequent migrant on an annual basis was A. ruthenus, observed in 6 out of 8 years. The most abundant young sturgeons during the first downstream migration were A. ruthenus with 599 specimens, followed by A. stellatus. For the species H. huso, only 7 specimens were registered for the entire period. The natural hybrids A. ruthenus × A. stellatus were quite frequent. One YoY specimen of A. gueldenstaedtii was registered after 10 years with no detections in the Lower Danube River. The catch per unit effort (CPUE/10 ha) was 0.346 for the whole period for all sturgeon species. This paper suggests a method for calculating the CPUE taking into account the studied area, with the goal of ensuring comparability of monitoring data between the countries of the Lower Danube. Recommendations are also made for better protection of the identified nursery site.
摘要:2014年至2021年,在多瑙河396公里处连续8年监测了四种鲟鱼(白鲟、星鲟、盖尔登斯泰迪鲟和胡索鲟)的年度幼鱼下游迁徙情况。在整个期间,共登记了713个同比标本。每年最频繁的移民是A.ruthenus,在8年中有6年被观察到。在第一次下游迁徙期间,数量最多的年轻鲟鱼是A.ruthenus,共有599个标本,其次是A.stellatus。在整个时期,胡索物种只有7个标本被登记。天然杂交种A.ruthenus×A.stellatus的发生频率较高。一个A.gueldenstaedtii的年环比标本在多瑙河下游10年后被登记,但没有检测到。所有鲟鱼物种在整个时期的单位努力渔获量(CPUE/10公顷)为0.346。本文提出了一种考虑研究区域的CPUE计算方法,目的是确保多瑙河下游国家之间监测数据的可比性。还提出了更好地保护已确定的苗圃场地的建议。

As I write, a Russian invasion into Ukraine is imminent. My father is next door in the kitchen, watching the evening news. I had planned on a swift kitchen entrance and exit: make a cup of tea, gobble down some bara brith (Welsh fruit cake made with black tea) and return to my editing without getting distracted. But tonight’s evening broadcast pulls me in with a kind of unwilling commitment; my eyes are glued to the screen. As – what seem like – hundreds of Russian tanks approach the Ukraine border in a desolate, muddy, barren landscape, I play a series of questions over and over in my mind: ‘where are all the birds? where are the trees and how can there be so many shades of grey in one landscape? how have the earthworms, beetles and bugs fared amongst the bombs, shells, the shrapnel and the deafening artillery?’ My guess is, probably not well. This experience led me to research the impact of warfare on biodiversity: something vastly overlooked and rarely documented, it turns out. According to The Conflict and Environment Observatory (2022), fighting on 24 February, close to Kherson in Ukraine, resulted in fires in the Black Sea Biosphere Reserve. These fires were detectable from space and may have destroyed trees and unique habitats for birds in the largest nature reserve in Ukraine. In times of crises and war we (understandably) put our human needs above anything else, forgetting the toll that war takes on our – already compromised – natural world. Armed conflict affects millions of people across the globe, with one in ten children living in areas impacted by conflict. Whilst the devastation that war brings for humans is well documented, its impact on biodiversity is less so (The Climatarian Blog 2017). According to the United Nation’s Environment Program, for over six decades, armed conflicts have occurred in more than two-thirds of the world’s biodiversity hotspots, thus posing critical threats to conservation efforts. The UN General Assembly declared 6 November the ‘International Day for Preventing the Exploitation of the Environment in War and Armed Conflict’. War preparations alone utilize up to 15 million square kilometres (km) of land, account for 6% of all raw material consumption, and produce as much as 10% of global carbon emissions annually (Bidlack 1996; Biswas 2000; Majeed 2004). Warfare can also impact local species populations and interaction. Following World War II, for example, the brown tree snake (Boiga irregularis) was introduced via former US bases on Guam Island, which led to the extirpation of more than 10 native bird and reptile species. Until now, ecologists have focused on the environmental consequences of specific war-related activities, such as nuclear testing, operational training, battlefield contamination and postwar refugee movements (Homer-Dixon 2001). This does not consider the whole picture. ‘Warfare Ecology’ is an emerging field however, which attempts to document the full impacts of war on ecology, rather th
在我写这篇文章的时候,俄罗斯入侵乌克兰迫在眉睫。我爸爸正在隔壁的厨房里看晚间新闻。我本来计划快速进出厨房:泡一杯茶,狼吞虎咽地吃点bara brith(用红茶制成的威尔士水果蛋糕),然后继续我的编辑工作,不要分心。但今晚的晚间广播带着一种不情愿的承诺把我拉了进去;我目不转睛地盯着屏幕。当数百辆俄罗斯坦克驶近乌克兰边境时,这片荒凉、泥泞、贫瘠的土地上,我的脑海里反复出现了一系列问题:“鸟儿都到哪里去了?”树在哪里?一处风景怎么会有这么多深浅不一的灰色?蚯蚓、甲虫和虫子在炸弹、炮弹、弹片和震耳欲聋的炮火中是如何生存的呢?我的猜测是,可能不太好。这段经历让我开始研究战争对生物多样性的影响:事实证明,战争对生物多样性的影响被广泛忽视,也很少有文献记载。根据冲突与环境观察站(2022),2月24日在乌克兰Kherson附近发生的战斗导致黑海生物圈保护区发生火灾。这些火灾可以从太空中探测到,可能已经摧毁了乌克兰最大的自然保护区的树木和鸟类的独特栖息地。在危机和战争时期,我们(可以理解的)把人类的需求放在第一位,忘记了战争对我们已经受到损害的自然世界造成的损失。武装冲突影响着全球数百万人,十分之一的儿童生活在受冲突影响的地区。虽然战争给人类带来的破坏有目可睹,但它对生物多样性的影响却不那么明显(the Climatarian Blog 2017)。根据联合国环境规划署的数据,60多年来,世界上超过三分之二的生物多样性热点地区发生了武装冲突,从而对保护工作构成了严重威胁。联合国大会宣布11月6日为“防止战争和武装冲突糟蹋环境国际日”。仅战争准备就占用了多达1500万平方公里的土地,占所有原材料消耗的6%,每年产生的碳排放量占全球的10% (Bidlack 1996;Biswas 2000;马吉德2004)。战争也会影响当地物种的数量和相互作用。例如,第二次世界大战后,棕树蛇(Boiga irregularis)是通过美国在关岛的前基地引入的,这导致了10多种本地鸟类和爬行动物的灭绝。到目前为止,生态学家一直关注特定战争相关活动的环境后果,如核试验、作战训练、战场污染和战后难民流动(Homer-Dixon 2001)。这并没有考虑到整体情况。然而,“战争生态学”是一个新兴领域,它试图记录战争对生态的全部影响,而不是具体的组成部分。它考察了战争的三个阶段:准备、战争和战后活动,并将生物物理系统和社会经济系统视为耦合系统(Machlis和Hanson 2008)。鸟瞰全局,保护平民的第一步最终是保护他们赖以生存的环境,我想知道战争生态学是否能从一个有用的角度来做到这一点。如果我们的读者中有战争生态学家,请务必与我们联系。从更乐观的角度来看,我很高兴地与大家分享,2022年将出版一本以森林为主题的《生物多样性》主题杂志。热带、温带和北方森林是世界上生物最丰富的陆地系统之一,为植物、动物和微生物提供了多种栖息地,并庇护着世界上绝大多数陆地物种。然而,根据《生物多样性公约》(CBD),在过去8000年里,地球上大约45%的原始森林覆盖已经消失,其中大部分是在上个世纪被砍伐的。探讨的一些主题将是森林及其生物多样性的治疗、精神、平静和培育作用。1,1 - 2 https://doi.org/10.1080/14888386.2022.2062447

ABSTRACT This study was carried out to assess crop diversity among smallholder farmers in Kogi State, Northern Nigeria. A multistage sampling technique was used to choose 302 crop farmers, and a well-structured questionnaire was used to generate the data. The information gathered was analysed using the Shannon and Simpson indices and the Poisson and Tobit regression models. The results show that crop production was dominated by male farmers on plots averaging 1.8 ha in size, with an average number of three crops grown per plot. The average values for the Shannon index and Simpson index are 0.34 and 0.85, respectively. The socio-economic factors explaining crop diversity in the area were the farmers’ age, level of education, household size, farm size and income. This study indicates policy strategies are needed that enhance technical knowledge and raise awareness of agro-crop biodiversity management. It also reveals a need for an increase in rural farm household incomes and greater investment in land reforms at both local and national levels in Nigeria.

ABSTRACT Citizen and community science is an important approach for advancing research, education, and conservation, and currently, various projects are being implemented and trialled worldwide. We conducted surveys of participants in the City Nature Challenge, an international event in which participants engaged in monitoring wildlife and plants in their neighbourhoods. We received responses from 361 participants representing 12 countries including the United States, Japan, the United Kingdom, and Malaysia. There were significant differences in terms of socio-demographic attributes and participants’ perceptions of citizen/community science activities. Regression analysis revealed that the more participants learned about the animals and plants in their areas, the more they self-reported their intention to participate in similar activities in the future in both the United States and Japan. This suggests that managers of citizen/community science projects could tailor the message and contents of the activities to enhance participants’ learning about local biodiversity to increase their continued involvement in future events. Key policy insights In both the United States and Japan, the more participants learned about the animals and plants in their local area through citizen/community science activities, the more they were willing to participate in similar activities in the future. Cross-cultural comparison of participants in citizen/community science activities revealed significant differences in terms of socio-demographic attributes (e.g. participants in Japan and Malaysia were younger than those in the United States and the United Kingdom). Survey results revealed differences in participants’ perceptions of the citizen/community science activities (e.g. participants from Malaysia were more likely to be aware of the threats to animals and plants in their neighbourhood than those in the United States, Japan, and the United Kingdom).
公民和社区科学是推进研究、教育和保护的重要途径,目前,世界各地正在实施和试验各种项目。我们对“城市自然挑战”(City Nature Challenge)的参与者进行了调查,这是一项国际活动,参与者参与监测他们社区的野生动植物。我们收到了来自美国、日本、英国和马来西亚等12个国家的361名参与者的回复。在社会人口统计学属性和参与者对公民/社区科学活动的看法方面存在显著差异。回归分析显示,参与者对他们所在地区的动植物了解得越多,他们就越愿意在美国和日本参加类似的活动。这表明公民/社区科学项目的管理者可以定制活动的信息和内容,以增强参与者对当地生物多样性的了解,从而增加他们对未来活动的持续参与。在美国和日本,参与者越多地通过公民/社区科学活动了解当地的动植物,他们就越愿意在未来参与类似的活动。公民/社区科学活动参与者的跨文化比较显示,在社会人口统计学属性方面存在显著差异(例如,日本和马来西亚的参与者比美国和英国的参与者年轻)。调查结果揭示了参与者对公民/社区科学活动的看法存在差异(例如,马来西亚的参与者比美国、日本和英国的参与者更有可能意识到他们附近的动植物面临的威胁)。

We received responses from 361 participants representing 12 countries including the United States, Japan, the United Kingdom, and Malaysia. There were significant differences in terms of socio-demographic attributes and participants’ perceptions of citizen/community science activities. Regression analysis revealed that the more participants learned about the animals and plants in their areas, the more they self-reported their intention to participate in similar activities in the future in both the United States and Japan. This suggests that managers of citizen/community science projects could tailor the message and contents of the activities to enhance participants’ learning about local biodiversity to increase their continued involvement in future events. Key policy insights In both the United States and Japan, the more participants learned about the animals and plants in their local area through citizen/community science activities, the more they were willing to participate in similar activities in the future. Cross-cultural comparison of participants in citizen/community science activities revealed significant differences in terms of socio-demographic attributes (e.g. participants in Japan and Malaysia were younger than those in the United States and the United Kingdom).

ABSTRACT Bhutan has an extensive protected area network and people living inside are integral partners with the conservation landscape. Despite this, little is known on local people’s traditional knowledge, cultural beliefs, and perceptions on wildlife. We investigated drivers of local knowledge, threats and cultural significance of the red panda (Ailurus fulgens) through semi-structured questionnaire surveys (N= 664 participants) on local residents in Jigme Dorji and Phrumsengla National Parks. A conditional inference tree analysis explained that knowledge of the red panda and encounters with the species varied by demography, occupation and locality. Although the majority of respondents were not knowledgeable of the species, residents living within the elevational range of red pandas exhibited greater knowledge. Civil servants, farmers, foresters, park staff, and teachers also had significantly greater knowledge of red pandas than monks, road workers, and students. Informally educated older (≥41 years) respondents placed higher cultural significance on the red panda relative to much younger respondents. Although past studies in Jigme Dorji National Park have identified habitat destruction and fragmentation due to linear infrastructural development – such as the construction of new power transmission lines – as significant anthropogenic threats to the red panda, respondents listed only non-timber forest products collection, forest fires, timber and firewood harvesting, climate change, livestock grazing, and kills by domestic dogs as some of the most prevailing threats to the red panda in our study area. Recognizing and incorporating the intrinsic value of wildlife within the protected area–people framework and utilizing traditional cultural perceptions of threatened species like the red panda, can be a valuable tool in strengthening public support for species conservation. This study further advocates an urgent need for educational programs to promote ecological and cultural values of the red panda in schools and the wider public.
摘要:不丹拥有广泛的保护区网络,居住在保护区内的人们是保护区不可或缺的合作伙伴。尽管如此,人们对当地人的传统知识、文化信仰和对野生动物的看法知之甚少。我们通过对Jigme Dorji和Phrumsengla国家公园当地居民的半结构化问卷调查(N=664名参与者),调查了红熊猫(Ailurus fulgens)当地知识、威胁和文化意义的驱动因素。条件推理树分析解释说,对大熊猫的了解以及与该物种的接触因人口、职业和地点而异。尽管大多数受访者对该物种并不了解,但生活在大熊猫海拔范围内的居民表现出了更多的了解。公务员、农民、林业工作者、公园工作人员和教师对大熊猫的了解也明显高于僧侣、道路工人和学生。与年轻得多的受访者相比,受过正规教育的年长(≥41岁)受访者对红熊猫的文化意义更高。尽管Jigme Dorji国家公园过去的研究已经将线性基础设施发展(如新输电线路的建设)导致的栖息地破坏和碎片化确定为对大熊猫的重大人为威胁,但受访者只列出了非木材森林产品收集、森林火灾、木材和木柴采伐、气候变化,在我们的研究区域,牲畜放牧和被家养狗杀死是对大熊猫最常见的威胁。在保护区-人的框架内认识和融入野生动物的内在价值,并利用对红熊猫等受威胁物种的传统文化认知,可以成为加强公众对物种保护支持的宝贵工具。这项研究进一步表明,迫切需要在学校和广大公众中开展教育项目,宣传大熊猫的生态和文化价值观。
