西双版纳地区小型哺乳动物群落结构及其季节变动

2008年10月—2009年6月,选择云南西双版纳地区7个不同类型生境,分别在旱季、雾凉季和雨季,采用铗夜法对小型哺乳动物群落展开调查。共布2100铗日,捕得小型哺乳动物3科10种127只,其中啮齿目(Rodentia)鼠科(Muridae)8种,食虫目(Instectivo-ra)鼩鼱科(Soricidae)和猬科(Erinaceidae)各1种,平均捕获率为6%。社鼠(Niviventer con-fucianus)是该地区小型哺乳动物群落中的优势种,其捕获率在季节之间的差异达到显著水平(P=0.023),在生境之间的差异不显著(P0.05)。在所调查的7个生境中,以生境最原始的热带雨林中的小型哺乳动物物种多样性指数最高(1.91);热带山地常绿阔叶林物种均匀度最高(0.95);热带季节性湿润林物种优势度最高(0.94)。人工橡胶林中未捕获到小型哺乳动物。3个季节中以旱季捕获小型哺乳动物数量最多。对不同生境内群落相似性指数进行聚类分析,6个生境在相似性指数0.21处全部聚合在一起。本研究结果表明,不同生境中小型哺乳动物物种多样性的丰富度与人类干扰程度有关,在人类干扰越小的生境中,小型哺乳动物种类越丰富,生物多样性指数越高;人为干扰频繁的生境物种多样性较低。     

陕西子午岭植物群落演替过程中物种多样性变化与环境解释

采用空间代替时间的方法研究了黄土高原子午岭植物群落自然演替过程中不同层α物种多样性的变化规律,并通过CCA分析了物种多样性与环境间的关系。结果表明:(1)随演替的进展,草本层物种丰富度、均匀度及物种多样性均逐渐降低(P0.05);灌木层物种的丰富度与物种多样性均呈现相似的"J"形变化趋势,而均匀度(虎榛子(Ostryopsis davidiana)群落除外)差异不显著(P0.05);乔木层物种丰富度、均匀度以及物种多样性差异均不显著(P0.05);群落总体物种丰富度随演替进展呈现明显的单峰模型,与中期物种丰富度假说一致。(2)林冠郁闭度是影响草本层和灌木层物种组成的主要环境因子(P0.01),其次为土壤养分和坡位;而坡位对乔木层物种组成的影响极显著(P0.01),这可能与乔木树种的更新差异有关。(3)群落演替是物种扩散和环境筛综合作用的过程,物种对演替过程中变化光照资源的响应差异可能是该区不同层物种多样性变化的主要原因。     

区域变动尺度上不同生境类型及环境因子对西双版纳蝴蝶多样性的影响

【目的】生境类型和环境因子对物种分布和维持具有重要的影响。本研究通过分析不同生境类型对蝴蝶群落多样性及其群落结构影响的差异,以及环境因子对蝴蝶物种丰富度和多度的影响,为区域变动尺度蝴蝶多样性维持机制的研究奠定基础。【方法】于2019年8月和10月,在西双版纳地区采用样线法,调查了天然林、次生林、复合生境、人工林和农田5种生境中蝴蝶的物种,分析了蝴蝶群落多样性、群落结构相似性及物种丰富度和多度与环境因子的关系。【结果】2019年从西双版纳共采集蝴蝶2 226头,隶属于11科98属175种,在西双版纳州级尺度上蝴蝶物种丰富度高于县域尺度。在西双版纳州级尺度上,蝴蝶的物种丰富度和多度在5种生境间存在显著差异,而在县域尺度上,物种丰富度、多度和Chao 1物种丰富度估计值没有一致性规律。群落结构相似性结果显示,在西双版纳州级尺度上,蝴蝶群落结构在不同生境类型间存在极显著差异,在县域尺度上,仅勐腊区域蝴蝶群落结构在不同生境类型间存在显著差异。蝴蝶物种丰富度和多度不仅受到生境类型的影响,还受到温度、年均降水和海拔的影响。【结论】本研究结果表明,在区域变动尺度上,生境类型对西双版纳蝴蝶的多样性的影响较大,而温度、年均降水和海拔是维持蝴蝶物种多样性的重要因素。这些发现对当前人类导致的生境丧失和气候变化时代生物多样性的保护具有重要意义。     

坝上地区农田及两种恢复生境中蜘蛛多样性与群落特征

蜘蛛是农田生态系统中重要的自然天敌,其生物多样性及群落特征直接决定了农田的害虫控制等生态系统服务功能质量。农田及其周边的恢复生境是蜘蛛重要的栖息地。本研究采用陷阱法,对河北省张家口市崇礼区871、1360、1635 m 3个海拔农田、自然恢复草地及人工修复林地的蜘蛛群落的物种组成、物种多样性和功能特征进行研究,分析不同恢复生境中蜘蛛群落特征。结果表明: 不同生境蜘蛛的物种多样性指数差异明显,人工修复林地蜘蛛的多度为124.3只,显著高于自然恢复草地(70.1)及农田(38.6)的蜘蛛多度;人工修复林地(16.3)与自然恢复草地(21.4)的物种丰富度没有显著差别,但均显著高于农田(8.9);人工修复林地(2.04)及自然恢复草地(2.05)的Shannon多样性指数差异不显著,且均显著高于农田(1.55)。3种生境的蜘蛛群落组成均具有显著差异;蜘蛛体长与蜘蛛捕猎类型呈正相关,大型蜘蛛倾向于通过捕猎获取食物;自然恢复草地与农田蜘蛛以游猎型为主,而人工修复林地倾向于拥有更多的结网型蜘蛛,高海拔地区的蜘蛛体积通常较小。自然恢复草地与人工修复林地均可以提升蜘蛛群落多样性,在区域生物多样性保护中起重要作用;不同生境蜘蛛群落组成出现了显著分化,即蜘蛛群落总体的功能特征发生改变和保留了部分生境特有种。2种恢复生境蜘蛛多样性指标优于农田生境,且2种恢复生境物种组成存在差异,均具有保护特有种的功能,研究结果对农田及区域尺度蜘蛛生物多样性保护与恢复具有指导意义。

新疆农田系统瓢虫资源调查与多样性研究

为全面了解新疆农田系统瓢虫资源组成以及多样性结构差异,本研究采用网捕法于2018年、2019年连续两年对新疆11个地州50个县/市/区15种农作物生境的406个采集点开展了瓢虫资源系统调查.结果表明:共获7001号瓢虫标本,隶属3亚科13属26种,其中多异瓢虫Hippodamia variegata为绝对优势种类,其个体数量占比达55.11％,深点食螨瓢虫Stethorus punctillum、龟纹瓢虫Propylea japonica等10种为常见种;不同生境瓢虫群落多样性分析显示,苜蓿田和麦田的丰富度指数(5.598150、7.546581)、多样性指数(0.874884、0.708508)、均匀度指数(0.661678、0.544575)都较高,但优势度指数则分别仅为0.224261、0.342884;大豆田和西瓜田的多样性指数、丰富度指数以及均匀度指数均显著低于其他生境类型(P<0.05),但优势度指数远高于其他生境,为0.663091、0.658502,可见苜蓿田、麦田等生境瓢虫物种数和个体数量丰富,且分布均匀,而大豆田和西瓜田种类相对贫乏,且分布不均匀;不同地州的瓢虫群落多样性分析显示,伊犁州的丰富度指数(7.363638)、多样性指数(0.970345)、均匀度指数(0.712583)都较高,但优势度指数仅为0.135821;阿克苏地区的多样性指数、丰富度指数以及均匀度指数都显著低于其他地州,但优势度指数远高于其他地州,为0.663477,可见伊犁州的瓢虫物种数和个体数量丰富,且分布均匀,而阿克苏地区种类相对贫乏,且分布不均匀;不同海拔带瓢虫群落多样性分析则显示,300 m～1300 m海拔区间农田瓢虫群落多样性指数和丰富度指数显著高于其它海拔区间,且低海拔(-130 m～300 m)或高海拔(1600 m～2800 m)区间的瓢虫群落丰富度和多样性指数较低,但优势度较高,这表明300 m～1300 m海拔区间内瓢虫种类比较丰富,而在低海拔或高海拔区间农田生境内的瓢虫物种贫乏,个体数量也比较少.本研究基本明确了新疆农田系统瓢虫资源组成及多样性,揭示了其生态系统和生物多样性保护中的重要价值,同时为生物防治提供了丰富捕食性天敌瓢虫资源.     

枸杞岛潮下带沙地生境鱼类群落结构和季节变化

为了解岛礁水域沙地生境的鱼类群落结构特征,评估该生境对鱼类资源养护的潜在作用,于2009年采用多网目组合刺网对枸杞岛潮下带沙质区域进行了逐月采样,同步设置岩礁为对照生境.应用α和β多样性指数结合相对重要性指数、相对渔获率、ABC曲线和聚类排序方法对两种生境中的鱼类组成、多样性变化和群落格局与变化进行了全面探讨.全年在沙地和岩礁生境共采集鱼类63种,隶属11目38科56属,2种生境各自出现的鱼类皆为46种.受暖水种频繁出现在沙地生境的影响,潮下带沙质区域鱼类区系比岩礁生境略显丰富,且春夏季的渔获量普遍高于岩礁生境;由于种类组成均匀度较低,沙地生境各季节的α多样性普遍较低,夏季显著低于岩礁生境.日本须鳎是沙地生境的指示种,为早春、夏末和秋冬季沙地底层优势鱼种.5-7月鳀、多数月份鲻和10月份鳗鲇等种类对沙地生境的阶段性利用,使其形成了区别于以趋礁性鱼类为优势类群的岩礁生境的群落格局和季节动态.沙地是多种鱼类幼鱼阶段的庇护所和饵料场,是鲆鲽类的良好栖息地.沙地生境在维持鱼类区系和养护鱼类资源方面具有重要作用.     

黄土丘陵沟壑区不同植被恢复类型昆虫群落结构及多样性的研究

为探讨黄土高原植被恢复过程中植物与昆虫群落的关系,评价人工植被和自然恢复植被种类搭配的合理性,为退化生态系统的植被恢复提供依据。采用样地调查法,在黄土丘陵沟壑区纸坊沟流域研究比较了不同植被恢复类型昆虫群落组成、结构及多样性的变化。结果表明,2种不同植被恢复类型区昆虫有189种(含蜱螨目),分别隶属13目84科。而不同植被恢复类型昆虫群落的物种数、丰富度、多样性、均匀度及优势度指数值均有明显差异。以20a自然封育植被恢复区昆虫群落的物种数、丰富度、多样性、均匀度指数值均较高,其值分别为160、21.17、1.4914和0.6918。优势度则以人工治理区(0.7251)>自然封育区(0.5845)。说明从人工治理区到自然封育区,随着植被种类增加,昆虫种类相应增加,优势种由突出降至不明显,昆虫群落稳定性提高。     

人工固沙植被恢复对地表节肢动物群落组成及多样性的影响

人工绿洲是干旱区主要的自然景观之一,为了维护绿洲稳定而营建的防护林强烈改变地表生态水文过程,进而影响着地上和地下生物多样性。然而,以往的研究对地上植被关注较多,而对土壤动物研究较少。以张掖绿洲外围人工固沙植被群落和天然固沙植被群落为研究对象,探讨人工固沙植被恢复对荒漠地表节肢动物群落组成及多样性的影响及不同动物类群对植被变化的响应模式。研究表明,天然固沙植被群落转变为人工固沙植被群落显著降低了地表节肢动物数量,但提高了地表节肢动物类群丰富度和多样性,这在5月份表现尤为明显。植被类型对地表节肢动物群落的影响不同,8月人工柽柳林群落地表节肢动物活动密度、类群丰富度和多样性均显著高于人工梭梭林群落。人工固沙植被恢复显著降低了适应荒漠环境的拟步甲科甲虫,而蚁科和部分蜘蛛的数量显著增加,它们对人工固沙植被恢复的响应模式不同决定了群落结构及多样性的变化规律。此外,研究还发现一些地表节肢动物类群对不同生境具有强烈的指示作用,如拟步甲科等可指示荒漠生境,潮虫科等可指示梭梭林生境,而蠼螋科和狼蛛科等可指示柽柳林生境。综上所述,人工栽植固沙灌木形成的固沙植被群落导致了一些适应荒漠环境的地表节肢动物类群的数量降低,但也为更多的地表节肢动物类群提供了适应栖居环境和充足的食物资源等,从而提高了地表节肢动物的多样性。     

Reef fish assemblages in north-western Sri Lanka: distribution patterns and influences of fishing practises

The distribution and abundance of reef fishes in relation to habitat structure were studied within Bar Reef Marine Sanctuary (BRMS) and on an adjacent reef, disturbed by destructive fishing techniques, in north-western Sri Lanka, by visually censusing 135 species groups using fifty metre belt-transects. Two types of continental shelf patch-reefs are found in the study area: coral reefs and sandstone reefs, which are divided into distinct habitats, four for the coral reef (shallow reef flat, shallow patch reef, deep reef flat and Porites domes) and two for the sandstone reef (structured sandstone-reef and flat sandstone-reef). Fish assemblages varied in structure between reef types and among habitats within reef types. Functional aspects of habitat structure and composition, such as available food and shelter, seemed to be important factors influencing distribution patterns. The strongest separation in the organisation of fish assemblages in BRMS was between reef types: 19% of all species were confined to the coral-reef patches while 22% were restricted to the sandstone reef patches and 59% were represented on both reef types. In terms of distribution among habitats, 21% of all species were restricted to one habitat while only 1.5% were present in all. The highest density of fish was in the coral reef habitats while highest species diversity was found in the most structurally complex habitat: the structured sandstone-reef. This habitat also had the highest proportion of species with restricted distribution. Planktivores were the most abundant trophic group in BRMS, and the species composition of the group varied among habitats. The comparison of the disturbed reef with BRMS suggested that habitat alteration caused by destructive fishing methods has strongly influenced the fish community. Within the fished area the structure of the fish assemblages was more heterogeneous, fish abundance was lower by an order of magnitude and species numbers were lower than in BRMS.     

Fish Assemblages on Estuarine Artificial Reefs: Natural Rocky-Reef Mimics or Discrete Assemblages?

If the primary goal of artificial reef construction is the creation of additional reef habitat that is comparable to adjacent natural rocky-reef, then performance should be evaluated using simultaneous comparisons with adjacent natural habitats. Using baited remote underwater video (BRUV) fish assemblages on purpose-built estuarine artificial reefs and adjacent natural rocky-reef and sand-flat were assessed 18 months post-deployment in three south-east Australian estuaries. Fish abundance, species richness and diversity were found to be greater on the artificial reefs than on either naturally occurring reef or sand-flat in all estuaries. Comparisons within each estuary identified significant differences in the species composition between the artificial and natural rocky-reefs. The artificial reef assemblage was dominated by sparid species including Acanthopagrus australis and Rhabdosargus sarba. The preference for a range of habitats by theses sparid species is evident by their detection on sand-flat, natural rocky reef and artificial reef habitats. The fish assemblage identified on the artificial reefs remained distinct from the adjacent rocky-reef, comprising a range of species drawn from naturally occurring rocky-reef and sand-flat. In addition, some mid-water schooling species including Trachurus novaezelandiae and Pseudocaranx georgianus were only identified on the artificial reef community; presumably as result of the reef''s isolated location in open-water. We concluded that estuarine artificial reef assemblages are likely to differ significantly from adjacent rocky-reef, potentially as a result of physical factors such as reef isolation, coupled with species specific behavioural traits such as the ability of some species to traverse large sand flats in order to locate reef structure, and feeding preferences. Artificial reefs should not be viewed as direct surrogates for natural reef. The assemblages are likely to remain distinct from naturally occurring habitat comprised of species that reside on a range of adjacent natural habitats.     

荣成俚岛人工鱼礁区游泳动物群落特征及其与主要环境因子的关系

根据2009年5月份至2010年2月份于山东荣成俚岛人工鱼礁区和对照区4个季度月的游泳动物及同步的环境调查数据,采用Margalef种类丰富度指数,Shannon-Wiener多样性指数,Pielou均匀度指数分析了鱼礁区游泳动物群落组成和物种多样性的时空分布特征,运用梯度分析法对调查区域游泳动物群落格局与环境因子进行排序分析,结合蒙特卡罗检验确定影响鱼礁区游泳动物群落结构的控制因子。调查期间共捕获游泳动物18种,隶属于8目15科,优势种为许氏平鲉(Sebastes schlegeli)、大泷六线鱼(Hexagrammos otakii)和斑头六线鱼(Hexagrammos agrammus),其中许氏平鲉在渔获量组成中占绝对优势(41%)。鱼礁区游泳动物的渔获种类数和渔获量高于各自对照区,但差异不显著(P>0.05), 季度月平均CPUE最高值出现在近岸礁区,达到830.24 g ·网^-1·d^-1。群落组成特征值上,春秋季的参数值最大,鱼礁区与对照区间并无显著差异(P>0.05)。聚类分析表明,春季、夏季和冬季均是季度月内不同区域的样方相似性较高,而秋季的远岸礁区及其对照区样方与春季各区域样方的相似性高于秋季近岸礁区及其对照区。RDA分析表明,水温对游泳动物群落组成变化的解释量为37.1%,是主要的解释因子(P=0.002)。水温和水深等环境因子主导了俚岛人工鱼礁区游泳动物群落结构的时空变化。     

Fish assemblages associated with urban structures and natural reefs in Sydney,Australia

Abstract Fish ecology in urban estuaries is poorly understood. As coastal landscapes are transformed, recognizing the impact that urban structures, such as marinas, seawalls and wharfs, have on local fish populations is becoming increasingly important. The extent to which fish are able to maintain natural ecological assemblages can be measured, to a certain extent, by how closely they mimic natural habitats. In Sydney Harbour, assemblages of fish associated with artificial structures were compared with those associated with natural rocky reefs. Sampling was carried out in five locations, each with a marina, swimming enclosure and natural reef. In each location, different habitats supported different assemblages, but differences between habitats were not consistent among locations. Subsequent sampling compared artificial and natural sites in three different areas in each of three different estuaries. Results indicated that differences in fish assemblages between artificial and natural sites were greater than differences between sites within each habitat, but there were no patterns among different positions in an estuary or from estuary to estuary. This study provides initial evidence that, although artificial habitats generally support the same species as found on natural reefs, assemblages usually differed between natural and artificial habitats. In addition, without knowing if these habitats do, in fact, sustain viable populations of fish, it would be premature to label artificial structures as effective habitat for fish.     

南沙群岛美济礁海域夏季浮游动物群落特征

浮游动物是珊瑚礁生态系统中的重要组成部分,但国内相关研究相对较少。利用2012年7月在南沙群岛美济礁海域开展的13个站次的海洋生物调查数据,对美济礁浮游动物的群落特征进行研究,表明:(1)美济礁浮游动物种类组成丰富,共出现15个类群138种(类)浮游动物;(2)优势种组成复杂、区域变化明显,单一种的优势度不高;(3)浮游动物平均密度和湿重生物量分别为117.70个/m3、69.01 mg/m3,浮游幼虫在总密度中所占比例最大;(4)浮游动物非常丰富,多样性程度较高。平均丰富度、多样性指数和均匀度分别为4.93、3.33和0.67;(5)浮游动物可划分为2个群落,分别为潟湖-礁坪区群落和向海坡群落;(6)受珊瑚礁不同生物地貌带的空间异质性和水动力条件的影响,美济礁浮游动物群落区域差异明显。潟湖区浮游动物多样性较高,生物量最低;礁坪区浮游动物数量大,但分布不均匀,且多样性水平最低;向海坡区浮游动物种类最多、多样性非常丰富,但栖息密度最低。     

The effects of substratum material and surface orientation on the developing epibenthic community on a designed artificial reef

Artificial reefs provide shelter and can be an important source of food for fish depending on the epibenthic community on the structure. The growth and diversity of this community is influenced by the substratum material and the surface orientation of the reef. Settlement plates of four materials (Perspex, sandstone, wood and steel) were deployed in three orientations (upwards, downwards and vertical) at a depth of 33 m on a designed artificial reef (DAR) off the coast of Sydney, Australia. After three months, the steel surfaces had lower invertebrate species richness, total abundance and diversity compared to other surfaces. Steel was not an ideal material for the initial recruitment and growth of epibenthic invertebrates. A longer duration would be required to develop a mature epibenthic community. Surface orientation had species-specific impacts. Surface material and orientation are important factors for developing epibenthic assemblages, and are thus likely to affect the broader artificial reef assemblage, including fish.     

青岛崂山湾人工鱼礁区底层游泳动物群落结构特征

基于2015年5月至2016年1月在青岛崂山湾人工鱼礁区的调查数据, 采用Margalef种类丰富度指数(d)、Shannon-Wiener多样性指数(H')、Pielou均匀度指数(J)、丰度/生物量曲线、等级聚类分析、SIMPER相似性百分比分析和非度量多维尺度排序(NMDS)分析, 对底层游泳动物群落结构和多样性进行研究。调查期间共捕获游泳动物61种, 隶属34科, 其中鱼类36种, 甲壳类22种, 头足类3种。优势种为日本蟳(Charybdis japonica)、许氏平鲉(Sebastes schlegelii)、大泷六线鱼(Hexagrammus otakii)、斑头鱼(H. agrammus)和星康吉鳗(Conger myriaster), 其中日本蟳(26.91%)和许氏平鲉(26.74%)的生物量占绝对优势。礁区游泳动物的渔获量和渔获种类数均多于对照区, 月平均单位捕捞努力量渔获量(CPUE)最高值出现在5月, 达到735.74 ± 316.59 g·net^-1·d^-1。游泳动物群落组成的特征值上, 7、8月的多样性指数较高, 但鱼礁区和对照区无显著差异(P>0.05)。丰度/生物量曲线表明, 5、6月游泳动物群落处于严重受干扰状态, 11月和次年1月群落处于相对稳定状态。聚类分析表明, 除1月外, 各月份不同区域的样方相似性都较高, 5、6月三亩前礁区的相似性最高, 达到86.21%。     

Herbivore abundance and grazing intensity on a Caribbean coral reef

Herbivory is a primary factor in determining the structure of coral reef communities. Spatial variation among reef habitats in the intensity of herbivory has been documented, but underlying variation in species composition and abundance within the herbivore guild has received little attention. The distribution and relative abundances of herbivorous fishes and sea urchins across several habitats were studied on the Belizean barrier reef off the Caribbean coast of Central America. Marked variation in total herbivore density as well as major changes in the composition of the herbivore guild were found across reef habitats. Acanthurids (surgeonfishes) predominated in shallow areas (< 5 m) while scarids (parrotfishes) were dominant in deeper habitats. Significant differences among habitats in an experimental assay of grazing intensity were strongly correlated with herbivore abundance. The spatial distribution of herbivorous fishes across reef habitats does not appear to be simply explained by differences in reef topography, but may depend on complex interactions among proximity to nearby shelter, predator abundance, density of territorial competitors, and local availability of food resources.     

The influence of various reef sounds on coral‐fish larvae behaviour

The swimming behaviour of coral‐reef fish larvae from 20 species of 10 different families was tested under natural and artificial sound conditions. Underwater sounds from reef habitats (barrier reef, fringing reef and mangrove) as well as a white noise were broadcasted in a choice chamber experiment. Sixteen of the 20 species tested significantly reacted to at least one of the habitat playback conditions, and a range of responses was observed: fishes were (1) attracted by a single sound but repelled by none (e.g. white‐banded triggerfish Rhinecanthus aculeatus was attracted by the barrier‐reef sound), (2) repelled by one or more sounds but attracted by none (e.g. bridled cardinalfish Pristiapogon fraenatus was repelled by the mangrove and the bay sounds), (3) attracted by all sounds (e.g. striated surgeonfish Ctenochaetus striatus), (4) attracted and repelled by several sounds (e.g. whitetail dascyllus Dascyllus aruanus was attracted by the barrier‐reef sound and repelled by the mangrove sound) and (5) not influenced by any sound (e.g. convict surgeonfish Acanthurus triostegus). Overall, these results highlight two settlement strategies: a direct selection of habitats using sound (45% of the species), or a by‐default selection by avoidance of certain sound habitats (35%). These results also clearly demonstrated the need to analyse the influence of sounds at the species‐specific level since congeneric and confamilial species can express different behaviours when exposed to the same sounds.
