Abstract:
Introduction: A large number of planktonic communities found in tropical lakes have not yet been recorded, limiting understanding of how these ecosystems function and of the role that organisms play within them. Objective: Add new records of previously described species and to contribute to the knowledge of the planktonic communities present in tropical mountain and lowland lakes of the northeast Colombian Andes. Methods: Planktonic samples were collected and physicochemical variables measured in nine tropical lakes. Organisms were identified and a bibliographic search was carried out in databases and research articles to the identification of the new records to Colombia. Results: We present the data corresponding to six physicochemical variables measured in tropical lakes of this region and expand the existing information on organisms present in tropical lakes with a list of 391 taxa (299 phytoplankton and 92 zooplankton). The proportion of planktonic species unique to tropical lakes and the low similarity between lake types found with a Jaccard analysis indicated high heterogeneity of ecological conditions in the studied lakes. Conclusions: The 391 taxa found and 15 new records contribute to the list of planktonic organisms present in tropical lakes located in high and low areas of the Colombian northeast Andes.

Abstract:
Much of our current knowledge about the genetic dynamics in range expansions originates from models, simulations and microcosm experiments that need to be corroborated by field data. Here, we report a neutral genetic pattern that matches the predictions of the genetic surfing theory. Genetic surfing occurs when repeated founding events and genetic drift act on the wave of advance of an expanding population, promoting strong spatial structure. In the range expansion of the tortoise Testudo graeca from North Africa to southeastern Spain, we found several genetic signatures consistent with surfing: a decrease of genetic diversity with distance from the initial founder area, clinal patterns in allele frequencies, rare African alleles which have become common at distal sites in the Spanish range, and stronger spatial differentiation in the expanded range than in the original one. Our results provide support for the theory that genetic drift can be an important force in shaping the genetic structure of expanding populations.

Abstract:
Abstract The life sciences underwent a dramatic transformation during the twentieth century, with an expansion in fundamental knowledge of the process of evolution and its molecular basis, through advances in health care that greatly extended human life, and by the combination of these advances to address the problem of conserving the many forms of life threatened by expanding human society. The essay highlights the worldwide emphasis on social welfare in the years 1945–1980 and the expanding role of international collaboration, especially in the International Biological Program and its advances in ecology and the notion of the biosphere, and in the emergence of molecular biology. This was also the era of the Cold War, yet military confrontation had fewer implications for life sciences than for the natural sciences in that era. After 1980, deregulation and neoliberalism weakened programs for social welfare, yet links among the varying strands of life sciences continued to grow, bringing the development of genomics and its many implications, expanding epidemiology to include reliance on social sciences, and deepening ecological studies as the Anthropocene became more and more prevalent. In sum, the experience of the life sciences should make it clear to world historians that scientific advance goes beyond the achievements of brilliant but isolated researchers: those same advances rely substantially on social movements, migration, and the exchange of knowledge across intellectual and physical boundaries.

Abstract:
Abstract For many species, human-induced environmental changes are important indirect drivers of range expansion into new regions. We argue that it is important to distinguish the range dynamics of such species from those that occur without, or with less clear, involvement of human-induced environmental changes. We elucidate the salient features of the rapid increase in the number of species whose range dynamics are human induced, and review the relationships and differences to both natural range expansion and biological invasions. We discuss the consequences for science, policy and management in an era of rapid global change and highlight four key challenges relating to basic gaps in knowledge, and the transfer of scientific understanding to biodiversity management and policy. We conclude that range-expanding species responding to human-induced environmental change will become an essential feature for biodiversity management and science in the Anthropocene. Finally, we propose the term neonative for these taxa.

Abstract:
The 2009 British Ecological Society's Annual Symposium entitled ‘Facilitation in Plant Communities’ was held at the University of Aberdeen, Scotland, from 20 to 22 April 2009. This was the first ever international meeting dedicated to the rapidly expanding field of facilitation. The aim of the symposium was to assess the current ‘state-of-play’ by contrasting findings from different systems and by looking outwards in an attempt to integrate this field with other related fields. It was also aimed at understanding how knowledge of facilitation can help understand community dynamics and be applied to ecosystem restoration. The symposium identified several key areas where future work is likely to be most profitable.

Abstract:
For the first time to our knowledge, we demonstrate that whole angiosperm individuals can survive gut passage through birds, and that this occurs in the field. Floating plants of the genus Wolffia are the smallest of all flowering plants. Fresh droppings of white-faced whistling duck Dendrocygna viduata ( n = 49) and coscoroba swan Coscoroba coscoroba ( n = 22) were collected from Brazilian wetlands. Intact Wolffia columbiana were recovered from 16% of D. viduata and 32% of Coscoroba samples (total = 164 plantlets). The viability of plants was tested, and asexual reproduction was confirmed. Wolffia columbiana is an expanding alien in Europe. Avian endozoochory of asexual angiosperm propagules may be an important, overlooked dispersal means for aquatic plants, and may contribute to the invasive character of alien species.

Abstract:
Scorpions are venomous synanthropic arachnids, in 2019 they were responsible for more than 37000 cases of envenomation in the state of Ceará, Northeastern Brazil. To update the knowledge about the scorpiofauna in Ceará, a distribution list of scorpions collected/received by municipal agents of the Health Surveillance Service was performed in 165 municipalities (89%) of Ceará (2018 – 2019) and deposited in the Dr. Thomaz Corrêa Aragão Entomology Laboratory scientific collection, including species distribution maps and ecological data. This study included a total of 999 scorpions from two families (Buthidae and Bothriuridae) and eleven species. The most abundant species were: Tityus stigmurus (40.1%), Jaguajir rochae (37.2%), Bothriurus asper (8.3%) and Bothriurus rochai (6.7%), mainly inhabiting municipalities in the Caatinga biome. The first record of Tityus confluens and Tityus maranhensis in the Sobral mesoregion is herein presented, expanding the distribution of these species in Brazil.

Abstract:
The article considers the process of expanding the subject and methods of research in modern environmental science. It is shown how, following the traditional biological science of ecology, new directions of ecological knowledge arise under the influence of research activities: social ecology, anthropoecology. Knowledge about a human being is achieved through the use of both natural and human sciences. A great step in expanding the subject of modern ecology was the intensive formation of human ecology in recent years, in which the need for the formation of a unity of natural science and socio-humanitarian research methods was reflected most clearly. In contrast to biological ecology, in which the main focus of research was the principles of natural science research, in social ecology, socio-humanitarian issues become dominant, and in human ecology-the synthesis of natural science and socio-humanitarian approaches. It's time to abandon the progressive illusions of the past and move on to the awareness of the specifics of sustainable civilizational development at the present stage. This sustainable development presupposes the co-evolution of society and nature, such a co-development of society and nature, in which both components of this single system do not oppose each other, do not conflict, but organically presuppose each other in their combined, harmonious development. Thus, now acting as a unified science that studies the interaction of the central coreof the system and its environment, ecology sets new guidelines for understanding the organization of scientific knowledge, the mood of the modern world picture is falling. A promising way for ecology is to grow into a modern universal organizational science. But this is a distant prospect. However, even now, such a renewed ecology can provide much for Russia’s search for its modern civilizational path, clarifying the organization of scientific knowledge, specifying the contours of the modern scientific picture of the world.

Abstract:
The nitric oxide synthases (NOS; EC 1.14.13.39) use L-arginine as a substrate to produce nitric oxide (NO) as a by-product in the tissue microenvironment. NOS1 represents the predominant NO-producing enzyme highly enriched in the brain and known to mediate multiple functions, ranging from learning and memory development to maintaining synaptic plasticity and neuronal development, Alzheimer’s disease (AD), psychiatric disorders and behavioral deficits. However, accumulating evidence indicate both canonical and non-canonical roles of NOS1-derived NO in several other tissues and chronic diseases. A better understanding of NOS1-derived NO signaling, and identification and characterization of NO-metabolites in non-neuronal tissues could become useful in diagnosis and prognosis of diseases associated with NOS1 expression. Continued investigation on the roles of NOS1, therefore, will synthesize new knowledge and aid in the discovery of small molecules which could be used to titrate the activities of NOS1-derived NO signaling and NO-metabolites. Here, we address the significance of NOS1 and its byproduct NO in modifying pathophysiological events, which could be beneficial in understanding both the disease mechanisms and therapeutics.

Abstract:
This chapter discusses the development and implementation of an interdisciplinary learning community between the departments of Dental Hygiene and Biological Sciences, correlating nutrition with oral health and oral cancer and its prevention by early screening. The goal of the project was to engage underrepresented, urban undergraduate students in civic learning, with an eye toward expanding learning capacities and civic responsibilities beyond the classroom. The project followed participation in the 2010 Summer Institute offered by the National Science Foundation’s Science Education for New Civic Engagements and Responsibilities (SENCER). Oral and Maxillofacial Pathology integrates basic science curriculum and applies this unified foundation knowledge to the clinical evaluation of disease, thereby closing the gap between didactic and applied material. Dental Hygiene students enrolled in Nutrition and Anatomy and Physiology will learn to connect this knowledge gained with practical application outside the natural sciences, which in turn will make these courses more interesting and relevant.
