1. Groundwater ecosystems offer vast and complex habitats for diverse microbial communities. Here we review the current status of groundwater microbial biodiversity research with a focus on Bacteria ...and Archaea and on the prospects of modern techniques for enhancing our understanding of microbial biodiversity patterns and their relation to environmental conditions. 2. The enormous volume of the saturated terrestrial underground forms the largest habitat for microorganisms on earth. Up to 40% of prokaryotic biomass on earth is hidden within this terrestrial subsurface. Besides representing a globally important pool of carbon and nutrients in organisms, these communities harbour a degree of microbial diversity only marginally explored to date. 3. Although first observations of groundwater microbiota date back to Antonie van Leeuwenhoek in 1677, the systematic investigation of groundwater microbial biodiversity has gained momentum only within the last few decades. These investigations were initiated by an increasing awareness of the importance of aquifer microbiota for ecosystem services and functioning, including the provision of drinking water and the degradation of contaminants. 4. The development of sampling techniques suitable for microbiological investigations as well as the application of both cultivation-based and molecular methods has yielded substantial insights into microbial communities in contaminated aquifers, whereas knowledge of microbial biodiversity in pristine habitats is still poor at present. 5. Several novel phylogenetic lineages have been described from groundwater habitats, but to date no clearly 'endemic' subsurface microbial phyla have been identified. The future will show if the rather low diversity generally found in pristine oligotrophic aquifers is a fact or just a result of low abundances and insufficient resolution of today's methods. Refined approaches complemented by statistically rigorous applications of biodiversity estimates are urgently needed. 6. Factors identified to control microbial diversity in aquifers include spatial heterogeneity, temporal variability and disturbances such as pollution with chemical anthropogenic contaminants. Although first insights into the importance of individual biogeochemical processes may be obtained from surveys of microbial diversity within functional groups, direct links to groundwater ecosystem functioning have rarely been established so far.

Understanding residents' perceptions of ecosystem services (ESs) is important for modern ecosystem management. However, these perceptions are often overlooked in managing nature reserves, leading to decreased residents' participation in policy implementation. This study proposes to investigate the perceptions and ecological concepts contained in ESs among residents using a questionnaire survey. The results showed that: (1) Residents prioritize supporting services and they value “leisure and recreation” the most, followed by “air purification” and “habitat for animals and plants”. (2) Perceptions of different ESs have significant spatial differences, and distance significantly affects residents' perceptions. (3) Most types of ESs are significantly correlated with each other, and indigenous ecological concept has a profound impact on their perceptions. (4) Education and livelihood play a positive effect on the perceptions of ESs, while nationality, gender, age, distance, and relief show a negative influence. Improving education levels, establishing community rules and regulations, strengthening humans and nature connections, using ecological indigenous concepts in environmental management, and integrating residents' perceptions into regional development planning are some suggested solutions. This research study provides valuable insights into incorporating residents' perceptions and indigenous knowledge into ecological management and policy development at local and regional levels.
Robust ecological paradigms and theories should, ideally, hold across several ecosystems. Yet, limited testing of generalities has occurred in some habitats despite these habitats offering unique ...features to make them good model systems for experiments. We contend this is the case for the ocean-exposed sandy beaches. Beaches have several distinctive traits, including extreme malleability of habitats, strong environmental control of biota, intense cross-boundary exchanges, and food webs highly reliant on imported subsidies. Here we sketch broad topical themes and theoretical concepts of general ecology that are particularly well-suited for ecological studies on sandy shores. These span a broad range: the historical legacies and species traits that determine community assemblages; food-web architectures; novel ecosystems; landscape and spatial ecology and animal movements; invasive species dynamics; ecology of disturbances; ecological thresholds and ecosystem resilience; and habitat restoration and recovery. Collectively, these concepts have the potential to shape the outlook for beach ecology and they should also encourage marine ecologists to embrace, via cross-disciplinary ecological research, exposed sandy beach systems that link the oceans with the land.
•Longitudinal study of children’s understandings of ecological concepts of energy and materials.•Understandings developed in a non-linear process of conceptual change.•Development was partially ...moderated by participation in earth education programs.
This paper focuses on the development of understandings of the ecological concepts of energy flow and materials cycling of middle school students. It is based on a qualitative analysis of individual interviews with 6 students in an urban area of the southern US conducted every year over a 5-year period in 2004–2008, starting in grade 4 and finishing in grade 8. In addition to their formal education, all of the students participated in three outdoor earth education programs (Earthkeepers, Sunship Earth & Sunship III) over a 4-year period. Specifically, the study analyzed what misconceptions connected with energy and matter emerged and how students’ conceptual understanding developed over time. In addition, it discusses the possible effects of educational programs on participating students. The study demonstrates the non-linear process of conceptual change, constrained by a few persistent students’ misconceptions. The study also discusses potential implications for the practice of outdoor educational programs.
The concept of ecosystem‐based fisheries management (EBFM) has been subjected to debate since it was introduced in the late 1990s. The development of the concept seems to follow two separate but ...simultaneous trajectories of increased popularity but also sustained critique. This paper offers an analysis of potential mechanisms behind these disparate trajectories by drawing on a theoretical framework from science and technology studies (STS) centred around "black box" and actor‐network theory. To support our analysis, we perform an exploratory literature review of how the EBFM concept has been used in a selection of high impact fisheries research papers. We find that the popularity of EBFM does not guarantee its integrity, usefulness or analytical insight, but also that persistent critique of how the concept is used seems to be driving some change. We think that a continued trajectory of increased understanding, contextualization and discernibility of EBFM can help overcome the considerable ambiguity associated with the concept and make it increasingly useful to fisheries management. This means moving away from routine use of the term towards a practicable and tangible approach to improve fisheries sustainability.
Scientific knowledge is a primary resource that scientists use to shape their activities to make sense of natural phenomena. Support for students’ adaptation of scientific knowledge can enhance their ...ability to make sense of the natural world. This study aims to examine how ecological concepts are used when students plan field-based modeling of ecological phenomena and to identify teachers’ support for students’ use of ecological concepts. This study adapts the categorization of ecological concepts as natural, functional, and integrative according to how they are used in ecological research. With this foundation, we examine a field-based modeling activity that was implemented in a middle school science club. The goal of this activity was to develop models that make sense of ecological phenomena through processes that involve field investigations. Video recordings and transcriptions of the activities were analyzed as the main data sources. The analysis results reveal how different types of ecological concepts are used in modeling and illustrate how teachers support students’ use of different ecological concepts. Based on these findings, we discuss instructional supports to expand the resources that students can use in field-based modeling of ecological phenomena and the importance of domain-specific knowledge in making sense of the natural world.
•Concepts for sustainable land use and management-orientated ecosystem research.•Knowledge development driven by conflicts in human–environmental interactions.•Ore Mountains as ...‘model-region’-subjected to aggravating environmental problems.•Future ecosystem adaptation to changing impacts.
Principles of sustainability were mentioned for the very first time in the Ore Mountains in Central Europe some 300 years ago, triggered by the shortage of timber. Always new problems and challenges occurred throughout history caused by changes in ecosystems, which influenced sustainability aspects. This region was marked by drastic environmental impacts, particularly strong SO2 immissions in the second half of the 20th century. Since the political transformation of 1989, both air quality and the functioning and integrity of ecosystems have improved and the rehabilitation of the destroyed forests and degraded peatbogs has begun. The ups and downs of landscape development, in particular the crises in the human–environment relationship in the region, were not only associated with changes in the ecosystem, but also with a process of gaining and structuring knowledge, concept development, and communications. In this paper, we provide a framework for assessing sustainable land use management, and to demonstrate it by way of examples of successful implementation in the Ore Mountains region. In this context we will focus on such important ecological approaches as the concepts of ecosystem research, ecological indicators, ecological integrity, and ecosystem services. Thus, we describe the demand for integrating available knowledge into conceptual approaches, and moving into implementation procedures by means of integrated land management.
Developing a practical tool in ecology that addresses the challenge of transferring the ecologicalconcept systematically has become an essential factor in achieving a better understanding of the ...teaching process. Three-layer Observation Framework (TlOF) is one of the best methods that can be adopted in designing practical work in ecology since its power in providing a step-by-step concept reconstruction. This research aimed to develop a sample of practical work in ecological teaching and learning based on the TlOF. This research followed the ADDIE method in developing the product with some modifications. The research focus was set to gain product’s appropriateness from validators and users.
