Methodology Series Module 7: Ecologic Studies and Natural Experiments
In this module, we will discuss study designs that have not been covered in the previous modules - ecologic studies and natural experiments. Go to: Ecologic Studies. In an ecologic study, the unit of analysis is a group or aggregate rather than the individual. It may be the characteristics of districts, states, or countries.

Ecological study
In epidemiology, ecological studies are used to understand the relationship between outcome and exposure at a population level, where 'population' represents a group of individuals with a shared characteristic such as geography, ethnicity, socio-economic status of employment. What differentiates ecological studies from other studies is that the unit analysis being studied is the group ...

From Theory to Methodology: Using Ecological Engagement to Study
However, translating his theoretical concepts in empirical studies has proved challenging. In this article, we describe a methodological approach—ecological engagement methodology (EEM)—that was designed to operationalize key elements of Bronfenbrenner's bioecological theory in studies of development in context.
Applications of structural equation modeling (SEM) in ecological
Aims This review was developed to introduce the essential components and variants of structural equation modeling (SEM), synthesize the common issues in SEM applications, and share our views on SEM's future in ecological research. Methods We searched the Web of Science on SEM applications in ecological studies from 1999 through 2016 and summarized the potential of SEMs, with a special focus ...
Four principles for improved statistical ecology

This paper has proposed guidelines to enhance statistical methodology for ecological studies suitable for use by individual researchers and research teams. While outside the scope of this work, undoubtedly there ...
Sampling and analysis frameworks for inference in ecology
Methods in Ecology and Evolution is an open access journal publishing papers across a wide range of subdisciplines, disseminating new methods in ecology and evolution. Abstract Reliable statistical inference is central to ecological research, much of which seeks to estimate population attributes and their interactions.
Ecological Research Methods: Observing, Experimenting & Modeling
Ecology is the study of the relationship between organisms and their environment on earth. Several ecological methods are used to study this relationship, including experimenting and modeling. Manipulative, natural or observational experiments may be used. Modeling helps analyze the collected data.

7.2
All variables (outcome, exposure, and covariates) are ecological. Partially Ecologic. Some, but not all, variables are ecological. Multilevel. Analyses may simultaneously include individual and ecological variables on the same construct (e.g., income). This could be called multilevel modeling, hierarchical regression, or mixed-effects modeling.
Research synthesis methods in ecology
Meta-analysis was introduced to the fields of ecology and evolution in the early 1990s, using methods borrowed largely from the social sciences, and then adapted for the questions and nature of the data in ecology and related fields such as evolutionary and conservation biology (Gurevitch et al. 2001; Lau et al. 2013).Meta-analysis is the quantitative synthesis of the results of different ...
Chapter 6. Ecological studies
In ecological studies the unit of observation is the population or community. Disease rates and exposures are measured in each of a series of populations and their relation is examined. Often the information about disease and exposure is abstracted from published statistics and therefore does not require expensive or time consuming data collection.
Ecological Research
Online publication from 2024. Ecological Research will be published in online-only format effective with the 2024 volume. This is a proactive move towards reducing the environmental impact caused by the production and distribution of printed journal copies and will allow the journal to invest in further innovation, digital development, and sustainability measures.
The design, applications, strengths and weaknesses of descriptive
Ecological studies are a useful means of performing international comparisons and studying group-level effects (for example, the correlation between deaths rates from cardiovascular disease and cigarette sales per capita). Strengths and Weaknesses. Descriptive (including ecological) studies are generally relatively quick, easy and cheap to conduct.
Methodology for Ecological Analysis
2.1 Introduction. Data, data collection, selection, and methodology play key roles in ecological analysis. Data collected by appropriate methodology, and with the proper organization are essential for good interpretation. Based on the scientific problem to answer, data collection procedures are designed for sampling.
A meta-analysis on global change drivers and the risk of infectious
Main. Emerging infectious diseases are on the rise, often originate from wildlife, and are significantly correlated with socioeconomic, environmental and ecological factors 1. As a consequence ...
Experience sampling method
The experience sampling method (ESM), also referred to as a daily diary method, or ecological momentary assessment (EMA), is an intensive longitudinal research methodology that involves asking participants to report on their thoughts, feelings, behaviors, and/or environment on multiple occasions over time. Participants report on their thoughts, feelings, behaviors, and/or environment in the ...
Convergence effect during spatiotemporal succession of lacustrine
Succession is a fundamental aspect of ecological theory, but studies on temporal succession trajectories and ecological driving mechanisms of pla. ... Detailed analysis methods of ecological assembly processes can be found in the Supplementary Materials and Methods. ... In this research, the microorganisms in the surrounding water continuously ...
Quantitative assessment of ecological risk from pollution ...
The combination of source analysis receptor model and risk assessment is an effective method to quantify source contribution. This study has quantified the ecological risks of soil heavy metals from different sources, which will provide a reliable method for the identification of primary harmfulness sources of pollution for future studies.
From isolation to linkage: Holistic insights into ecological risk
While landscape ecological risk assessment (LERA) has the potential to positively impact environmental concerns by informing land use policies, a holistic perspective has yet to be adopted in previous investigations of LERA in relation to land use change. To address this gap, our study introduces a novel research framework that applies landscape ecology principles and methodologies, utilizing ...
Frontiers
The study also revealed that the different growth processes of the two simulated phytoplankton species did not contribute positively to the increased Chla concentrations. However, further research is needed to investigate the impacts of different phytoplankton functional groups on the marine ecological environment under the influence of typhoons.

This study introduced a method for reconstructing aquatic vegetation landscapes impacted by water level fluctuations using the Qianshiliying coal mining subsidence wetland, located in the Yanzhou mining area of the eastern part of the Huanghuai River, as a case study. The findings from this research were then utilized in ecological restoration ...
