生态学

Author suggest that established system of Eco-toxicology in Paleoecology, to prevent toxicant into body for us, to against foreign living intrude , to study Eco-toxicology and that established principles of law to protect from ecological safety, living things safety and food safety for our country and people.

作者就研究恐龙灭绝对我们今天的意义提出了一些新的见解，认为"中毒说"丰富了古生态学，为建立古生态毒理系统提供了依据；启示我们谨防生活中的毒物，严防境外有毒有害生物入侵，加强生态毒理学研究，进一步健全法律保障体系，确保生态安全，生物安全和食品安全。

Paleoecology The investigation of prehistoric ecology as revealed by studying fossils and ancient human artifacts, pollen samples, and the mineral deposits in which such structures occur.

古生态学：指对史前生态研究的学科。主要通过研究远古形成的化石以及古人类遗迹，花粉(参见 palynology)标本以及矿质沉淀以描述当时生态环境。

Some of the regional changes analyzed are Baltimore-Washington urbanization, Great Lakes landscape change, Upper Mississippi River vegetation, Greater Yellowstone biodiversity, Southwestern US paleoecology, Palouse bioregion land use history, Northeastern forest dynamics, and land use history of the Colorado Plateau.

分析了一些区域变化，如：Baltimore-华盛顿城市化、大湖区景观变化、密西西比河上游植被、大黄石地区的生物多样性、美国西南地区古生态学、Palouse生物区土地利用历史、东北地区森林动力学、以及科罗拉多高原的土地利用历史。

Dr. Campbell trained in the U.S. including as a post-doc at the NASA Ames Research Center, in the fields of paleontology, paleoecology, paleoenvironmental analysis, sedimentology, stratigraphy, geochemistry, and astrobiology.

Dr。 Campbell 一直在美国从事着古生物学、古生态学、古环境研究、沉积学、地层学、地球化学和天体生物学方面的学习和研究工作，曾在 NASA Ames Research Center (美国宇航局艾姆斯研究中心)进行博士后研究。

The Diatom Paleolimnology Data Cooperative is a database of diatom and associated ecological and paleolimnological data useful in studying global change.

硅藻古湖沼学数据库为全球变化研究提供了有关硅藻植物数据、古湖沼学和其它生态学数据和记录等。

The concept of metacommunities and the paleontological notion of chronofauna show much promise for synthesis of paleontology and ecology.

集合群落的概念以及地质时期动物群的古生物学认识显示，将古生物学和生态学结合在一起是大有希望的。

At leaf scale, TJ photosynthesis model was selected and Gao stomatal conductance model was proved suitable for semi-arid region after comparing with BBL model through the parameter regression and analysis of model sensitivity. Plant physio-ecological characteristics were analyzed based on the parameters gained from the nonlinear regression using TJ model and Gao model with field experimental data. As C4 photosynthesis types Zea mays and Panicum miliaceum 's carboxylation coefficient are bigger than the others.

在叶片尺度上，选择TJ模型作为叶片尺度所使用的光合模型，并对景观模拟中经常用到的Ball-Berry模型和Gao模型进行比较，通过参数拟合和模型的敏感性分析，选择Gao模型作为叶片尺度的气孔导度模型，应用模型模拟的结果，分析了研究区主要植物种的生理生态学特性。C4光合型的玉米和糜子，羧化速率系数大，光合能力强。

Second, from the point of view of ecology, vegetarianism has egoistic and altruistic advantage if we believe paragenesis is inevitable.

第二部份：是以生态学的观点为著眼，它分别从自然生态、生物互助的共生伦理，来强调素食利己与利他的优点。

The larval parasitism of DBM by this parasitoid in the field usually ranges from 40 % to 70 %, with the highest parasitism rates of more than 90%, indicating high practical potential of this parasitoid to be integrated in the management of DBM....
