Understanding the effects of human–inducedperturbations, “disruptions”, on ecosystemfunctions is essential to be able to designsustainable environmental practices for theprotection of biodiversity. It has been well-documented on all continents that Euro-American cultures have had severe anddeleterious effects upon biodiversity during thelast three centuries (Deloria 1996). Humanimpacts since New World colonisation haveaccelerated species extinctions and thedisruption and degradation of ecosystemsprocesses and services, many of which havealready been reduced to isolated fragments, andnumerous species and genetically distinctpopulations have been lost in the process. Infact, between one-third to one half of the landsurface have been transformed by human action(Vitousek et al. 1997) and is currently composedof what Brown et al. (2003) call “semi-naturalmatrix” or “...land neither intensively used forcities or agriculture nor set aside as naturalreserves.” Perhaps more disturbing are the lesswell-known and more subtle disruptions tofundamental ecosystem processes: theconsequences of which are yet to be seen.During this new millennium, the tragedy ofthe commons is likely to become morecommon, particularly in developing countrieswhere the pressures are both global and local.Under these circumstances, environmentalscientists face the challenge of providing theinformation upon which future social andenvironmental policy needs to be based. Thischallenge requires a careful scrutiny andexamination of scientific data, models andother available empirical evidence within aninterdisciplinary setting. Other critical tasksinclude: (1) the explicit consideration of theinteraction between science and society indeveloping sustainable initiatives (Bradshaw B namely the comparison ofNorth and South Americas.North and South American ecosystemsshare a long history of cultural and ecologicalinteractions and have sustained similartransformations and disruptions through humanimpacts.

了解人为干扰(“破坏”)对生态系统功能的影响,对于设计保护生物多样性的可持续环境实践至关重要。在过去的三个世纪里,欧美文化对生物多样性产生了严重而有害的影响,这在各大洲都有充分的证据。自新大陆殖民以来,人类的影响加速了物种灭绝,破坏和退化了生态系统过程和服务,其中许多已经减少到孤立的碎片,许多物种和遗传上独特的种群在此过程中消失了。事实上,三分之一到二分之一的陆地表面已经被人类活动所改变(Vitousek et al. 1997),目前由Brown et al.(2003)所称的“半自然矩阵”或“……土地既没有集中用于城市或农业,也没有作为自然保护区。”也许更令人不安的是对基本生态系统过程的不太为人所知和更微妙的破坏:其后果尚待观察。在这个新的千年里,公地悲剧可能会变得更加普遍,特别是在发展中国家,那里的压力是全球性和地方性的。在这种情况下,环境科学家面临的挑战是为未来的社会和环境政策提供所需的信息。这一挑战需要在跨学科的背景下仔细审查和检查科学数据、模型和其他可用的经验证据。其他关键任务包括:(1)明确考虑科学与社会在发展可持续举措中的相互作用(Bradshaw B,即南北美洲的比较)。北美和南美的生态系统有着悠久的文化和生态相互作用的历史,并在人类影响下经历了类似的转变和破坏。两个大陆都受到诸如enso现象等大规模气候驱动因素的影响。在某种程度上,北美和南美在气候和生物模式上互为镜像。在北美和南美的西部地区尤其如此,那里主要的生态系统类型分别沿着相似的地理和地质环境发展。北美和南美的温带地区有着惊人的气候相似之处,尽管它们在生物地理、文化和社会经济方面存在差异。例如,对全球环流模式的分析(Lauenroth et al. 2004)预测,在CO的效应加倍的情景下

BackgroundBehavior and activity patterns largely determine animal’s fitness and their ecological roles. Those patterns depend on many factors, being body mass, sex and age the most relevant in mammals. Particularly, those factors altogether with environmental conditions could influence movement behavior of mammals that hibernate, such as the Monito del monte (Dromiciops gliroides).MethodsTo evaluate its movement behavior and activity we radio-tracked D. gliroides 12 individuals (8 females and 4 males, corresponding to 5 adults and 7 sub-adults) during the austral summer. With the estimated locations we estimated home ranges, core areas and their relationship with body mass. We also assessed movement speed during early (19:00 to 01:00 h), peak (01:00 to 03:00 h) and late (03:00 to 07:00 h) activity periods. This study was conducted at the San Martín experimental forest (Valdivia, southern Chile).ResultsEstimated home range areas were 1.04 ± 0.20 ha, and core areas were 0.27 ± 0.06 ha; we found no significant differences between males and females, nor between adults and sub-adults. Home range and core areas were independent of body mass in females but showed positive relationships in males. Core area overlap was larger between sub-adult and adult individuals (35%) than between adult males and females (13%). Average movement D. gliroides speed was 1.45 m/min, reaching its lowest value during the peak activity period (01:00 to 03:00 h), but being faster during early and late activity periods. Those speed differences may be related to travelling and foraging activities.ConclusionHome range and core areas estimated here showed a large variability, which can be related to environmental factors. Home range size was positively correlated with body mass on males but not on females. Also, lower movement speeds at the peak activity period suggest that D. gliroides concentrates feeding activities at this time. As D. gliroides disperses the seeds of at least 16 native plant species, its movement behavior also has important consequences at the community level.
行为和活动模式在很大程度上决定了动物的适应性及其生态作用。这些模式取决于许多因素,其中体重、性别和年龄与哺乳动物最相关。特别是,这些因素与环境条件一起可能影响冬眠的哺乳动物的运动行为,例如Monito del monte (Dromiciops gliroides)。方法在南方夏季对12只黄颡鱼(雌雄各8只,成虫5只,亚成虫7只)进行无线电跟踪,以评价黄颡鱼的运动行为和活动。根据估计的位置,我们估计出了运动范围,核心区域以及它们与体重的关系。我们还评估了活动早期(19:00至01:00 h)、高峰(01:00至03:00 h)和后期(03:00至07:00 h)的运动速度。这项研究是在San Martín实验森林(智利南部瓦尔迪维亚)进行的。结果家庭活动范围面积为1.04±0.20 ha,核心区面积为0.27±0.06 ha;我们发现雄性和雌性之间没有显著差异,成年和亚成年之间也没有显著差异。家庭范围和核心区域与女性体重无关,但与男性呈正相关。亚成虫和成虫之间的核心区重叠面积(35%)大于成年雄雌之间的核心区重叠面积(13%)。平均移动速度为1.45 m/min,在活动高峰期(01:00 ~ 03:00 h)达到最低,活动前期和后期移动速度较快。这些速度差异可能与旅行和觅食活动有关。结论本区和核心区具有较大的变异性,可能与环境因素有关。家庭范围大小与男性体重呈正相关,但与女性体重无关。此外,在活动高峰期,移动速度较低,表明油纹姬鼠在此时集中了摄食活动。在传播至少16种本地植物种子的同时,它的移动行为在群落水平上也具有重要的影响。

BackgroundDensity in inter and intraspecific plant-plant interactions affects the action modes of allelopathy (autotoxicity, negative and positive allelopathy). Some seeds exude compounds that inhibit the germination of others. Ipomoea murucoides and I. pauciflora are sympatric tree species that form patches at the local scale where one or the other dominates, possibly due to allelopathy in the seeds. The objective of this study was to determine the possible density-dependence of the allelopathic effect among seeds of these species through the measure of seed germination and seedling emergence.MethodsIn both species, allelopathy was measured as: a) germination in mixed sowing of both species at different proportions, b) germination in single-species trials at different densities after adding seed extracts of both species, and c) seedling emergence in seed mixtures of both species sown at different proportions beneath canopies of the two Ipomoea species.ResultsSeed germination of I. murucoides was increased by the presence of I. pauciflora and diminished at higher densities of its own seeds; however, seed germination of I. pauciflora was not affected by the presence of I. murucoides seeds. The addition of extracts (either from conspecifics or congeneric) diminished the germination of both species and at higher seed densities the germination was lower. Seedling emergence did not depend on the species under which the seeds were sown nor on the density of the seeds.ConclusionsThe germination experiments evidenced positive allelopathy and/or autotoxicity, while there was no evidence of allelopathic effects in seedling emergence. The allelopathic activity is reported in the seeds of these species for the first time.

BackgroundHuman activities are permanently threatening wildlife. Wildlife Rescue and Rehabilitation Centers (WRRC) have served for the rescue, rehabilitation and reinsertion of affected and recovered animals.MethodsWe reviewed the casuistry of five wildlife rescue and rehabilitation centers in Chile over 5 years, and described the main causes of admission, most affected taxonomic groups and final outcomes of the admitted individuals, shedding light into general patterns and relevant factors currently affecting wildlife in Chile. To understand the current work and status of WRRC system in Chile, we also conducted a qualitative survey to WRRC personnel and Agricultural and Livestock Service (SAG) regional offices regarding their operation.ResultsA total of 3418 cases of animals admitted to WRRC were obtained; 95.3% corresponded to native species. Of native animal cases, 86.0% corresponded to birds, 12.3% were mammals and 1.7% reptiles. Trauma was the most frequently observed cause of admission in all three native fauna groups (35.8% in birds, 23.2% in mammals, 27.8% in reptiles).ConclusionsWRRC are a tool for conservation and education of wild animal species in Chile, however WRRC and SAG regional office personnel highlighted several deficiencies in the current system and suggested opportunities for improvement. The current WRRC system needs modernization and financial support from the Chilean state to fulfil their relevant mission.
