Marine intrusions drive short-term and long lasting changes on limnological dynamics along the water column of a tropical coastal lagoon Limnologica (IF 1.7) Pub Date : 2023-11-02 Jorge Gabriel Fernandes Genovez, Théo Dias Arueira, Luís Alfredo dos Santos Prado, Giovanna Figueiredo Lima da Silva, Claudio Cardoso Marinho, André Luiz dos Santos Fonseca, Murilo Minello, Daniel Basílio Zandonadi, Rodrigo Lemes Martins, Francisco de Assis Esteves, Anderson da Rocha Gripp
Non-tidal coastal lagoons are widespread aquatic ecosystems distributed along coastlines. They exhibit complex limnological dynamics influenced by geomorphology, land use, atmospheric processes, and oceanic exchange. Although such shallow ecosystems are described as vertically homogeneous, sandbar breaching events can quickly modify the water column by promoting seawater intrusion, which is the primary

Streams and rivers are the most threatened and exploited freshwater ecosystems worldwide. Land-use changes, particularly the conversion of forests to agricultural, residential, and industrial areas, have greatly impacted them, leading to declining water body quality and biodiversity loss. Thus, evaluating rivers and identifying threats is crucial to protect and rehabilitate them adequately. A combination

Can osmotrophy in Gonyostomum semen explain why lake browning drives an expansion of the alga in parts of Europe? Limnologica (IF 1.7) Pub Date : 2023-07-14
Gonyostomum semen experiences a remarkable expansion in parts of Europe, partially driven by rising levels of dissolved organic matter (DOM), also called lake browning. One way to explain the stimulating effect of browning is to assume that G. semen combines photosynthesis with osmotrophy, the ability to utilize DOM as source of nutrients or energy. The present work tested this idea on a nearly unialgal

Foraging morphology and diet divergence of European whitefish (Coregonus lavaretus) in water courses of Murmansk region Limnologica (IF 1.7) Pub Date : 2023-01-07 E.M. Zubova, N.A. Kashulin, P.M. Terentyev, D.B. Denisov, S.A. Valkova, A.A. Cherepanov, S.V. Postnova, A.V. Melekhin
European whitefish (Coregonus lavaretus) is a highly polymorphic species. In general, it is assumed that the divergence in whitefish is a form of a specialization in the use of the resources (including food) of the main limnological zones – pelagic (plankton), littoral (benthos, plankton), profundal (benthos) – and the morphological adaptations of the shape of the body and head simultaneously determine

Central America and the Caribbean, at the northern limit of the Neotropical region, is made up of a narrow strip of land and numerous islands, with a complex geological history, represents an important biogeographic connection between North and South America and contains diverse freshwater environments, including high mountain and lowlands lakes and wetlands. We examined literature reports and databases

Communication with local community and stakeholders as a key activity to protect oligotrophic streams with freshwater pearl mussel Limnologica (IF 1.7) Pub Date : 2023-01-02 Ivana Tycova, Robert Ourednik, Ondrej Spisar
A complex approach in nature and species conservation is crucial for a real and persisting success of the costly work and effort. A combination of both direct support of the endangered species together with habitat restoration, and cooperation with community members and authorities, present and active within the species’ habitat, is a must. Nevertheless, the latter is often missing in nature conservation

Using machine learning models to assess the population dynamic of the freshwater invasive snail Physa acuta Draparnaud, 1805 (Gastropoda: Physidae) in a tropical urban polluted streams-system Limnologica (IF 1.7) Pub Date : 2023-01-03 Siméon Tchakonte, Paul-Alain Nana, Antoine Arfao Tamsa, Nectaire Lié Nyamsi Tchatcho, Ernest Koji, Fils Mamert Onana, Gideon Aghaindum Ajeagah
The poor understanding of the spread conditions and the geographical patterns of the exotic freshwater snail Physa acuta in sub-Saharan Africa urban streams makes it difficult to design and implement sustainable management tools, especially in deteriorating global and local environments. This study aimed to determine the ecological preferences and the major environmental variables associated with P

High-throughput sequencing and marker pigment analysis of freshwater phytoplankton: A direct comparison with microscopic count data in the tropical crater lakes of Western Uganda Limnologica (IF 1.7) Pub Date : 2023-01-05 Heidi Tanttu, Dirk Verschuren, Wannes De Crop, Angela Nankabirwa, Christine Cocquyt, Bjorn Tytgat, Elie Verleyen
High-throughput DNA sequencing (HTS) and photosynthetic marker-pigment analysis can provide cost-and time-efficient alternatives for morphology-based microscopic identification and counting of lacustrine phytoplankton. However, application of particularly HTS in tropical lakes is still uncommon. We analyzed the community composition of cyanobacterial and eukaryotic phytoplankton in relation to trophic

Community-level physiological profiles in biofilms from streams differently affected by a volcanic eruption Limnologica (IF 1.7) Pub Date : 2023-01-05 Verónica Díaz Villanueva, Uara Carrillo, Beatriz Modenutti
Volcanic eruptions are catastrophic events that allow testing different impacts on the ecosystems. Inputs of volcanic sediments into stream water may lead to drastic changes in the biota; however, the effects on biofilm functional traits remain poorly understood. This field study aimed to evaluate differences in structural and functional traits in the biofilm of streams differentially affected by the
