“…The numerous statistical relationships identified with canonical correlation between FFG biomass and physical and chemical variables corroborate the statements of Ryan and Curtis (2007), who suggest that physical factors control the distribution and abundance of functional groups, which determines the structure of the community. Silva and Henry (2013) also have demonstrated that the dissolved oxygen and pH have a great number of significant positive correlations with the different AMI taxa associated to Eichhornia azurea.…”

“…It has been shown through simulations that variations in DO concentrations affect the trophic structure of the AMI community in artificial wetlands and that this influence is greater for the herbivores (Spieles and Mitsch, 2003). With respect to phosphorus, Ryan and Curtis (2007) demonstrated that the Everglades are limited by this nutrient; therefore, an increase in its concentration favors groups such as Hirudinea, gastropods, dipteran, and oligochaetes, while coleopteran, heteropteran, and isopods are less influenced by phosphorus. In Jaboque, phosphorus is abundant, and it therefore does not seem to limit the development of the AMI community.…”

Aquatic macroinvertebrates (AMI) play an important role in the ecology of wetlands, either by their job as regulators of the cycles of matter, as for their energy storage function represented in their biomass, which is transferred to higher trophic levels. To answer the question of how biomass of different AMI trophic guilds is related with physicochemical variables in the wetland Jaboque (Bogotá, Colombia), four samplings were achieved between April 2009 and January 2010, according to periods of rain and drought in the region. The AMI biomass values obtained were rated as of intermediate rank. No temporal but spatial significant differences were found. Apparently these spatial differences appear to be associated with variations in anthropogenic pressure, which differs in each area of the wetland. In dry months (January and August), biomass was greater and dominated by detritivores. We observed a positive relationship between the specific conductance of water and the biomass of predators and detritivores and between water temperature and the biomass of detritivores and shredders. These relationships suggest that the physical and chemical variables influence the distribution, abundance, and biomass of functional groups. The physical and chemical conditions of water exhibited spatiotemporal fluctuations related to changes in the concentration of organic matter and nutrients, which presumably were related to the affluents discharges and the high impact of local human populations.Keywords: biomass, aquatic macroinvertebrates, urban wetlands, Jaboque, Andes. Biomassa de macroinvertebrados e características físicas e químicas da água em um pantanal urbano dos Andes na Colômbia ResumoMacroinvertebrados aquáticos (MIA) desempenham um importante papel na ecologia das zonas úmidas, quer pelo seu emprego como reguladores dos ciclos da matéria, como para a sua função de armazenamento de energia representada na sua biomassa, que é transferido para elevados níveis tróficos. Para responder à questão de como a biomassa de diferentes categorias tróficas de MIA está relacionada com as variáveis físicas e químicas da água do pantanal Jaboque (Bogotá, Colômbia), quatro amostragens foram realizadas entre abril de 2009 e janeiro de 2010, de acordo com os períodos de chuva e seca na região. Os valores de biomassa de MIA obtidos foram classificados como de grau intermediário. Nós não encontramos nenhuma diferença significativa no tempo, mas foram observadas diferenças espaciais. Aparentemente, estas diferenças parecem estar associadas com as variações espaciais na pressão antrópica, que difere em cada região do pantanal. Nos meses de menor precipitação (janeiro e agosto), a biomassa foi maior e dominado por detritívoros. Observou-se uma relação positiva entre a condutividade específica da água ena biomassa de predadores e detritívoros e entre a temperatura da água e a biomassa de detritívoros e trituradores. Estas relações sugerem que as variáveis físicas e químicas influenciam a distribuição, abundância e biomassa de grupos fu...

“…We quantified the covariation between algal and bacterial production within each stream and assessed whether this covariation was correlated across streams with several metrics of nutrient availability to periphyton. Based on evidence from other systems (i.e., King and Richardson 2007), we suspected that epilithon nutrient content would track the gradient of nutrient enrichment in surface water. In particular, we were interested in relating the degree of coupling between epilithic algal and bacterial production to the nutrient content of the epilithon itself.…”

“…The small number of applied/conservation papers that did not clearly fit at least one of the main subject headings were classified as Miscellaneous. We excluded purely faunistic or nonscientific surveillance investigations and the many studies in which results were reported for odonates but that did not explicitly target odonates (e.g., Gee et al 1997, Maxted et al 2000, King and Richardson 2007. However, we did count studies of broader issues that used odonates and other taxa as model or target groups (e.g., Siegfried 1993, Richter et al 1997, Palmer 1999, Le Viol et al 2009, Rosset et al 2013.…”

The academic study of dragonflies and damselflies (odonatology) is well established, but relatively limited attention has been given to odonates in the context of applied ecology and conservation science. We used the Web of Science ™ and Odonatological Abstract Service (ISSN 1438-0269) to capture trends in primary literature, characterize study features (habitats, life stages, etc.), identify research themes, and suggest future directions for odonatology in freshwater applied ecology and conservation science. We found no papers in this area prior to 1980, and 411 papers from 1980 through 2013. Nearly 75% of these papers were recent (since 2005) and >40% were very recent (since 2010). We identified several broad and overlapping research themes: 1) model taxa, 2) tools and indicators, 3) odonate-centered work, and 4) methodological issues and improvements (field sampling, data modeling/simulation, conservation/landscape-scale genetics). We found more reliance on fieldbased observational approaches than experiments and model-driven exercises, although the number of papers using model-driven exercises is rapidly increasing. We found a strong focus on adult stages, odonate assemblages, the Odonata as a whole, and studies of particular species. We identified research priorities in areas such as ecological valuation and management, monitoring and assessment, climate change and landscape planning, concordance with other taxa, effects of urbanization, data modeling/simulation, and rare-species ecology and conservation. To help establish an identity and facilitate communication, we suggest naming this diverse realm "applied odonatology". We think applied odonatology has a good future for a range of topics from conservation genetics and population ecology to assessments of anthropogenic impacts and the conservation of biodiversity. Key words: dragonflies, assessment, climate change, monitoring, landscape planning, freshwater health, biodiversity conservationThe academic study of dragonflies and damselflies (odonatology) is well established. However, relatively few odonatologists work outside of taxonomy and systematics, behavioral ecology, evolutionary ecology, and other prominent areas of classical research. The major books (Corbet 1999, Córdoba-Aguilar 2008), treatises (e.g., Corbet 1980, Stoks and Córdoba-Aguilar 2012), and flagship journals of odonatology reveal a productive legacy, but also relatively limited attention to matters of applied ecology and conservation science. For example, <5% of the 275 papers published during [2009][2010][2011][2012][2013] in Odonatologica and the International Journal of Odonatology are clearly relevant to applied ecology or conservation science. Nevertheless, the relatively few odonatologists working in this area and researchers based in other fields who often or sometimes use odonates as principal study subjects are making important contributions.A growing body of dragonfly-related research deals with the study or use of odonates in the context of freshwater applied ecolo...
