Study on Seasonal Dynamics of Rodent Community Structure in Different Habitats of Dafengmen Forest Farm and Its Surrounding Areas in Zengcheng District of Guangzhou
The purpose is to investigate the seasonal dynamics of rodent community structure across different habitats within an agroforestry ecotone, enrich local rodent community ecology data, and provide a reference basis for rodent population forecasting and scientific control. Study plots were established along a habitat gradient (farmland area, farmland-forest ecotone, forest area) around Dafengmen Forest Farm in Zengcheng District, Guangzhou City. Rodent community structure and its spatiotemporal dynamics were systematically surveyed quarterly using the snap-trapping method. A total of 134 rodents were captured, belonging to 7 species, 4 genera, and 1 family, namely Bandicota indica, Leopoldamys edwardsi, Niviventer fulvescens, Rattus andamanensis, Rattus losea, Rattus norvegicus, and Rattus tanezumi. The capture rate was highest in farmland (2.00%), followed by forest, and lowest in the ecotone. Seasonal capture rates ranked as summer > autumn > winter > spring. Community species composition differed significantly among habitats and seasons. Community diversity metrics (e.g., richness, Shannon-Wiener index, Pielou index, Simpson index, Margalef Richness index) were highest in farmland, followed by the ecotone, and lowest in forest, with overall higher values in winter and spring than in summer and autumn. Under seasonal shifts, the coefficients of variation for capture rate and community diversity indices were higher in forest habitats than in farmland, with the ecotone intermediate, indicating greater community stability in farmland habitats. Significant spatiotemporal dynamics in rodent density, species composition, and community diversity were observed in the study area, related to habitat heterogeneity, food resource abundance, anthropogenic disturbance, and rodent ecological traits. The rodent community structure within the agroforestry ecotone formed by mosaic of natural forest and farmland is unique, necessitating targeted control strategies and techniques.

为了探索气候变化对鼠类灾变规律的影响,摸清黔中地区不同气候环境鼠类活动最适宜的温度与降雨区间范围,本研究通过对黔中地区息烽县1987—2017年鼠情监测数据与历年温度和降雨的关系进行分析研究,结果表明：黔中地区温度和降雨与当地鼠类种群数量关系密切,且鼠类各种群对气候因子有一定的适应性,不同气候条件（温度与降雨）与鼠类种群数量均存在线性关系。鼠类最适温度区间范围值为22.1~25.0℃,并达到种群数量高峰,而降雨最适宜区间范围值为180.1~210.0 mm,且在住宅区、稻田区、旱地区3种生境鼠类种群均达到数量高峰,当降雨高于210.1 mm时,住宅区种群数量略有下降,旱地区种群数量略有上升,稻田区却趋于平稳,鼠类种群数量随年降雨量起伏,表现为一定的相关关系。

为黑线姬鼠预测预报、防控及自然生态环境治理提供依据，探讨其种群数量、种群组成的年度、月份、季节变化规律。在稻田、旱地耕作区采用夹夜法，对贵州省凯里市1984—2022年稻田、旱地耕作区黑线姬鼠捕获率进行年度、月份、季节种群动态进行分析。结果表明：黑线姬鼠在该地区主要分布于稻田区和旱地耕作区，占总鼠数的62.36%，各年度间种群组成比例在50.69%~94.44%，为当地绝对优势鼠种，是主要的监测和防控对象。不同年度黑线姬鼠种群数量存在显著差异，各年度间平均捕获率为0.70%~6.38%，相互间存在9.11倍差异，平均捕获率为3.92%；1984—1992年捕获率较高，平均为4.86%，处于种群密度较高的波动较大状态；2011—2022年捕获率较低，平均为1.20%，处于种群密度较低的稳定状态。不同月份及季节间种群数量存在显著差异，不同月份以7月最高，2月最低，捕获率分别为3.52%、0.95%；不同季节以夏季最高，冬季最低，捕获率分别为3.05%、1.29%。该分析得出黑线姬鼠是凯里市鼠类绝对优势种，近10 a来处于种群密度较低的稳定状态，7月和夏季种群数量最高；该研究为黑线姬鼠列为凯里市主要鼠类监测、防控对象，为准确做出预测预报，制定合理的综合防控措施及自然生态环境治理提供了重要依据。

Disturbance by military maneuvers over short and long time scales may have differential effects on grassland communities. We assessed small mammals as indicators of disturbance by military maneuvers in a mixed prairie in southern Oklahoma USA. We examined sites on two soil series, Foard and Lawton, across a gradient of disturbance intensity. A MANOVA showed that abundance of small mammals was associated (p = 0.03) with short-term (cover of vehicle tracks) disturbance but was not associated (p = 0.12) with long-term (loss of soil organic carbon, SOC) disturbance intensity. At the individual species level, Sigmodon hispidus (cotton rat) and Peromyscus maniculatus (deer mouse) occurred across all levels of disturbance and in both soil types. Only P. maniculatus abundance changed (p < 0.01) with short-term disturbance and increased by about one individual per 5% of additional track-cover. Abundance of P. maniculatus also increased (p = 0.04) by about three individuals per 1% increase in soil carbon. Chaetodipus hispidus (hispid pocket mouse) and Reithrodontomys fulvescens (fulvous harvest mouse) only occurred in single soil types limiting their potential as more general indicators. Abundance of P. maniculatus was positively related to shifts in plant species composition and likely reflected changes in vegetation structure (i.e. litter depth) and forage availability resulting from disturbance. Peromyscus maniculatus may be a useful biological indicator of ecosystem change because it responded predictably to both long-term and short-term disturbance and, when coupled with soil, plant, and disturbance history variables, can reveal land condition trends.

\n Urbanization is rapidly transforming much of Southeast Asia, altering the structure and function of the landscape, as well as the frequency and intensity of the interactions between people, animals, and the environment. In this study, we explored the impact of urbanization on zoonotic disease risk by simultaneously characterizing changes in the ecology of animal reservoirs (rodents), ectoparasite vectors (ticks), and pathogens across a gradient of urbanization in Kuching, a city in Malaysian Borneo. We sampled 863 rodents across rural, developing, and urban locations and found that rodent species diversity decreased with increasing urbanization—from 10 species in the rural location to 4 in the rural location. Notably, two species appeared to thrive in urban areas, as follows: the invasive urban exploiter\n Rattus rattus\n (\n n\n = 375) and the native urban adapter\n Sundamys muelleri\n (\n n\n = 331).\n R. rattus\n was strongly associated with built infrastructure across the gradient and carried a high diversity of pathogens, including multihost zoonoses capable of environmental transmission (e.g.,\n Leptospira\n spp.). In contrast,\n S. muelleri\n was restricted to green patches where it was found at high densities and was strongly associated with the presence of ticks, including the medically important genera\n Amblyomma\n,\n Haemaphysalis\n, and\n Ixodes\n. Our analyses reveal that zoonotic disease risk is elevated and heterogeneously distributed in urban environments and highlight the potential for targeted risk reduction through pest management and public health messaging.\n

目的 研究农村城镇化后不同生境鼠类的群落结构,为开展鼠害的科学治理提供基础依据。方法 采用夹夜法调查农村城镇化后鼠类的群落结构,每个样区布放300个夹夜,夹距5 m,夹线间距50 m以上,鼠夹晚放晨收。结果 农村城镇化后,城镇与农田结合部成为鼠类最重要的栖息环境,家栖鼠类的数量和生物量大幅度增加,野栖鼠类的优势度明显下降,主要表现为:在城镇和农田结合部,褐家鼠为第一优势鼠种和危害最大的害鼠;在离开城镇500 m的农田,黄毛鼠为第一优势鼠种,其次为褐家鼠,板齿鼠、褐家鼠和黄毛鼠是危害最大的害鼠;而在离城镇2 km的农田,黄毛鼠为第一优势鼠种,其次为小家鼠,黄毛鼠和板齿鼠是危害最大的害鼠。结论 农村城镇化间接为鼠害的发生提供了有利条件,引起农田鼠类群落发生一定程度的改变,必须针对这种变化趋势加强鼠害的可持续治理工作。

目的 应用DNA条形码技术对广东省江门市新会区农田捕获的鼠类进行种类鉴定和分析，为研究鼠形动物的多样性及鼠害防治奠定基础。方法 以2017年12月在广东省江门市新会区农田捕获的45只鼠为研究对象，分别提取鼠基因组DNA，采用通用引物扩增线粒体细胞色素C氧化酶亚基Ⅰ（COⅠ）基因片段并进行测序，将测序结果在美国国立生物技术信息中心中进行BLAST序列同源性比对，采用邻接法构建分子进化树，基于双参数模型计算遗传距离。结果 45只鼠样本均能通过PCR扩增出特异性基因片段，通过BLAST比对共鉴定出4种鼠（黄毛鼠、黄胸鼠、褐家鼠和黑缘齿鼠），37只鼠样本与形态学鉴定结果一致，为黄毛鼠；8只鼠样本存在形态鉴定错误，经复核，其中5只鼠重新鉴定为黄胸鼠，2只为幼年褐家鼠，另外1只为黑缘齿鼠。对45条序列进行比对分析发现有131个变异位点，单倍型分析结果显示有12个不同的单倍型。黄毛鼠种内遗传距离为0~1.2%，不同鼠种间遗传距离为7.1%~11.6%，平均遗传距离为（10.1±0.7）%，分子进化分析结果显示，同一种鼠类的个体聚为一支，支持率均为100%，能区分不同鼠种。结论 DNA条形码技术能够有效区分形态相似的近缘种，纠正形态学鉴定中的错误。

We determined the combined impacts of habitat degradation and recurrent cyclones on a community of small mammals in a rainforest landscape in Madagascar. We used capture-release and morphometry data of 609 individuals of shrew tenrecs, rodents, and nocturnal lemurs, and vegetation surveys from 360 plots in four sites with different degradation levels for four field seasons (2021–2023) separated by two cyclone events. Combined impacts of degradation and cyclones significantly affected small mammals’ diversity and capture abundance and only the body mass of the lesser tufted-tailed rat and brown mouse lemur. Diversity, capture abundance and body mass decreased immediately after the cyclones, and bounced back 4–5 months later, except in the forest fragment. We also examined the independent effects of habitat degradation using vegetation structure as it had more impacts than cyclones on small mammals. Plant diversity, canopy cover percentage, mean diameter at breast height, and estimated height significantly impacted small mammals’ diversity, capture abundance, and body-mass with species-specific variations. Our results suggest that recurrent cyclones may act as an intermediate disturbance factor, while habitat degradation might have permanent impacts on small mammals, emphasizing the importance of long-term monitoring of wild populations to understand their spatiotemporal dynamics and their effective conservation.
