To assess whether the annual killifish Nothobranchius wattersi responds plastically to a desiccation risk and whether this response is life stage dependent, life-history traits such as maturation time, fecundity and life span were experimentally measured in N. wattersi that were subjected to a drop in water level either as juveniles, as adults or both as juveniles and adults. Fish that were exposed to simulated pool drying as juveniles did not show changes in reproductive output or life span. Adults reacted by doubling short term egg deposition at the cost of a shorter lifespan. Overall, these results suggest that annual fish species can use phenotypic plasticity to maximize their reproductive output when faced with early pond drying, but this response appears to be life-stage specific. In addition to frogs and aquatic insects, phenotypic plasticity induced by forthcoming drought is now also confirmed in annual fishes and could well be a common feature of the limited number of fish taxa that manage to survive in this extreme environment.

Stakeholder Analysis on Ecosystem Services of Lake Manyara Sub-basin (Tanzania): How to Overcome Confounding Factors

Luc Janssens de Bisthoven, Maarten Vanhove, Anne-Julie Rochette, Jean Huge, Luc Brendonck

Summary: Ecosystem services are important for discussing natural resource management with stakeholders. A stakeholder analysis in the Lake Manyara sub-basin in Tanzania identified different groups with varying levels of influence and interest. An improved stakeholder analysis framework can contribute to better decision support systems in water basins.

Temporal dynamics of a subtropical floodplain pool after 2 years of supra-seasonal drought: a mesocosm study

Lizaan de Necker, Ruan Gerber, Johan van Vuren, Victor Wepener, Nico J. Smit, Luc Brendonck

Summary: South Africa experienced a severe drought that dried up waterbodies, but the study found that the drought did not affect the natural colonization and succession of aquatic invertebrates. However, if the drought persists, it could lead to local extinction of aquatic populations and loss of biodiversity.

Egg banks in dryland wetlands provide information on the diversity and vulnerability of branchiopod communities along a longitudinal aridity gradient

Elizabeth Meyer-Milne, Luc Brendonck, Tom Pinceel

Summary: Due to the continued degradation of wetlands and the rapid decline of freshwater biodiversity, it is necessary to identify vulnerable species for conservation and management efforts. In this study, we assessed the vulnerability of branchiopod communities in dryland landscapes using egg bank abundance and morpho-species richness as indicators. Our results showed that the branchiopod communities became more vulnerable along an aridity gradient and that egg bank abundance decreased with alkalinity.

Microalgal cultivation on grass juice as a novel process for a green biorefinery

Floris Schoeters, Eli S. J. Thore, Audrey De Cuyper, Isabelle Noyens, Sarah Goossens, Sander Lybaert, Erik Meers, Sabine Van Miert, Marcella Fernandes de Souza

Summary: Green biorefineries aim to sustainably produce chemicals, materials, proteins and energy by processing green biomass, such as grass, into a solid fraction (fibers) and a liquid fraction (green juice) for further refining. In this study, microalgae cultivation was incorporated in the green biorefinery concept to obtain a higher protein production from green juice obtained from grass.

Large branchiopod occurrence and community structure in relation to land-use types in temporary ponds of northern Tanzania

Summary: Large branchiopods are crucial for temporary ponds' ecosystems and their disappearance in Tanzania due to human activities is a concern. In this study, we compared temporary ponds in protected areas with those in communal lands, and found that land-use types affect the structure of large branchiopod community. We found six large branchiopod species, including one new species, and identified the most abundant and widely occurring species. The variation in community structure was influenced by the presence of Nothobranchius killifish and orthophosphate concentration. Understanding the relationship between land-use types and large branchiopod communities can guide the management of temporary pond ecosystems.

Playing Peekaboo with a Master Manipulator: Metagenetic Detection and Phylogenetic Analysis of Wolbachia Supergroups in Freshwater Invertebrates

Summary: In this study, a new metagenetic method was developed for detecting the co-occurrence of different Wolbachia strains in freshwater invertebrate host species. Three supergroups of Wolbachia were identified: a new supergroup V in Crustacea and Bivalvia hosts, supergroup A in Crustacea, Bivalvia, and Eutardigrada hosts, and supergroup E infection in the Crustacea host microbiome community.

Chronic handling stress in zebrafish Danio rerio husbandry

Charlotte Philippe, Lucia Vergauwen, Kato Huyghe, Gudrun De Boeck, Dries Knapen

Summary: The zebrafish is an important fish model species in scientific research. Handling the fish can cause stress, impacting fish welfare and experimental outcomes. The study found that even short handling routines can induce stress responses in zebrafish, and researchers should consider this when conducting measurements or behavioral trials within an hour after handling.

Substrate colour guides turquoise killifish's (Nothobranchius furzeri) choice of preferred spawning habitat

Eli S. J. Thore, Wouter Merckx

Summary: A laboratory experiment showed that turquoise killifish have a preference for black sand for spawning, depositing significantly more eggs compared to white or orange sand. This finding contributes to our understanding of the species' biology and can guide optimal husbandry and experimental conditions.

Elevated dissolved carbon dioxide and associated acidification delays maturation and decreases calcification and survival in the freshwater crustacean Daphnia magna

Lana Ramaekers, Bram Vanschoenwinkel, Luc Brendonck, Tom Pinceel

Summary: Increasing pCO(2) in freshwater environments may lead to acidification, which could negatively affect the survival, growth, and calcification of freshwater organisms. In this study, elevated pCO(2) and associated acidification were found to reduce the survival and calcium content of Daphnia magna, as well as slow down their growth and delay maturity. This is likely due to interference with the calcification process under elevated pCO(2) and low pH conditions.

Environmental risks of a commonly used pyrethroid: Insights from temporary pond species of the Lake Manyara Basin, Tanzania

Summary: Environmental risks posed by widespread pesticide application have attracted global attention. Chemical risk assessments in aquatic environments typically rely on toxicity data from classic model species, but complementary data based on local species are needed for unusual living environments. This study conducted an environmental risk assessment of cypermethrin using local temporary pond species, and compared the results to those obtained using classic model species.

Long-term exposure to a pharmaceutical pollutant affects geotaxic behaviour in the adult but not juvenile life stage of killifish

Eli S. J. Thore, Birgit Vanden Berghen, Luc Brendonck, Tom Pinceel

Summary: Ecosystems worldwide are being polluted by pharmaceutical compounds, which can disrupt wildlife behaviour. Despite a large body of literature, there is a lack of long-term studies across different life stages to accurately estimate the ecological outcomes of pharmaceutical pollution. In this experiment, fish exposed to the antidepressant fluoxetine showed smaller body size and changes in their position in the water column during adulthood, highlighting the importance of considering ecologically relevant timescales when studying the ecotoxicology of pharmaceuticals.

Summary: This article presents 22 marine species of Dalytyphloplanida from Cuba, Panama, and Lanzarote, of which 16 are new to science. Phylogenetic analysis and detailed morphology were used to classify and describe new taxa. The study also proposes new species synonyms and the establishment of a new family. Additionally, the classification of thalassotyphloplanid families was revised based on morphological and molecular data.
