Resource level modifies heatwave responses in the freshwater snail Lymnaea stagnalis Freshwater Biol. (IF 2.7) Pub Date : 2024-03-16 Otto Seppälä, Georgios Katsianis, Veronika Stabauer, Katri Seppälä, Tiina Salo
Predicting climate change‐mediated environmental effects on organisms is difficult because their direction and strength may depend on multiple ecological factors that vary in nature. This is because the effects of environmental factors often interact. One potentially important factor modifying organisms' thermal performance is their resource level. We experimentally examined the dependence of phenotypic

Trophic impact of an invasive mysid shrimp depends on zooplankton community composition: A mesocosm experiment Freshwater Biol. (IF 2.7) Pub Date : 2024-03-16 Katalin Patonai, Anett Endrédi, Zsófia Horváth, Péter Borza, Károly Pálffy, Péter Dobosy, Csaba F. Vad
Invasive species are a major threat to the structure and functioning of freshwater ecosystems, yet their functional roles in the invaded habitats are often poorly understood, especially in omnivores. Their impact on the invaded ecosystems may be strongly dependent on local species composition, but so far there is little evidence to support this. We ran a mesocosm experiment to test whether the top‐down

Long‐term droughts change the hatching patterns of zooplankton resting eggs from permanent and temporary lakes Freshwater Biol. (IF 2.7) Pub Date : 2024-03-13 Anderson L. Vargas, Thamires Brazil, Jayme M. Santangelo, Reinaldo L. Bozelli
Resting eggs are commonly produced by zooplankton inhabiting permanent and temporary lakes. Although resting eggs are acknowledged to survive varying harsh conditions, the effects of desiccation on the viability and hatching patterns of resting eggs are not fully understood and might be context‐dependent. This study simulated one long‐term (1 year) dry‐out episode in wet sediments originating from

Seasonal differences in amounts of oviposition habitat and egg‐laying by caddisflies in rivers with regulated versus unregulated flows Freshwater Biol. (IF 2.7) Pub Date : 2024-03-10 Handoko Wahjudi, William D. Bovill, Andrew J. Brooks, Barbara J. Downes
Few studies consider spatio‐temporal variation in egg‐laying for benthic insects in streams. However, such variation can have lasting effects on the numbers and distribution of offspring and subsquent life‐cycle stages. For species that require specific egg‐laying habitats, such as rocks that protrude from the water surface (emergent rocks, ER), densities of egg‐laying habitat can affect densities

Temporal dynamics of invertebrate community assembly in Lake Victoria since the late Pleistocene based on chitinous remains Freshwater Biol. (IF 2.7) Pub Date : 2024-03-06 Leighton King, Colin Courtney‐Mustaphi, Maria Cuenca‐Cambronero, Giulia Wienhues, Nare Ngoepe, Moritz Muschick, Yunuen Temoltzin‐Loranca, Hendrik Vogel, Martin Grosjean, Willy Tinner, Andrew Cohen, Mary Kishe, Oliver Heiri, Ole Seehausen, Blake Matthews
Preserved assemblages of invertebrate remains in lacustrine sediment reveal temporal variations of community composition and environmental conditions. However, records for large tropical lakes are scarce. Lake Victoria, the largest tropical lake, has a dynamic history of changes in water level, biogeochemistry and fish community composition over the past ~17,000 cal yr BP. In order to quantify changes

Evaluating effectiveness of restoration to address current stressors to riverine fish Freshwater Biol. (IF 2.7) Pub Date : 2024-03-06 Jane S. Rogosch, Hadley I. A. Boehm, Ralph W. Tingley, Kiah D. Wright, Elisabeth B. Webb, Craig P. Paukert
River restoration programmes with the goal of conserving and rehabilitating inland fishes have a multi‐decadal history, but evaluation and synthesis of past restoration actions have been limited by a lack of monitoring and reporting. Given that calls for both monitoring and systematic reviews of restoration have increased, we were interested in the influence that restoration has had on improving conditions

Long-term differences in population structure, body size and distribution patterns of amphipods and isopods in wetlands with declining hydroperiods Freshwater Biol. (IF 2.7) Pub Date : 2024-03-05 H. E. Emery-Butcher, S. J. Beatty, B. J. Robson
1 INTRODUCTION Changes in climate and land-use are some of the greatest threats to biodiversity across freshwater, marine and terrestrial biomes (Sala et al., 2000). Impacts in drying climates include increased evaporation (e.g., McFarlane et al., 2020), shorter hydroperiods (e.g., Sim et al., 2013) and increased air and water temperatures (Andrys et al., 2017; Barron et al., 2012).

1 INTRODUCTION Since the 1960s, streams have become among the most threatened habitats on earth because of human impacts (Dudgeon et al., 2006; Reid et al., 2019). Land-use and climate change, introduced species, overfishing, construction of dams and channelisation, and pollution by contaminants and microplastics, are all major threats to stream ecosystems (Allan, 2004; Hester & Gooseff, 2010; Reid

1 INTRODUCTION Aquatic macrophytes are important components of freshwater shallow lakes and are involved in many trophic interactions and other ecological processes (Søndergaard & Moss, 1998). Dense macrophyte cover can heavily influence lake ecosystem dynamics by stabilising clear water conditions and structuring biological assemblages (Scheffer et al., 1993; Thomaz et al., 2008).

1 INTRODUCTION Trait-based approaches have received growing interest from freshwater researchers in recent decades (Litchman & Klausmeier, 2008; Martini et al., 2021; Townsend & Hildrew, 1994).

1 INTRODUCTION Dissolved organic matter (DOM) plays a fundamental role in freshwater ecosystem structure and function through regulation at the base of the food web (Creed et al., 2018; Prairie, 2008; Williamson et al., 1999).

What determines mate choices? Heterospecific mating in Sympetrum dragonflies Freshwater Biol. (IF 2.7) Pub Date : 2024-02-09 Veronika Kornová, Eva Bílková, Petr Pyszko, Aleš Dolný, Stanislav Ožana
1 INTRODUCTION Epigamous behaviour in dragonflies is associated with visual stimuli (Corbet, 1999; Svensson et al., 2007). When species with similar mating signals reproduce simultaneously at the same site, heterospecific sexual interactions may occur (McPeek & Gavrilets, 2006; Verzijden & Svensson, 2016). This behaviour can be more frequent between species that are closely related or have diverged

They are, however, exposed to substantial and ever-increasing anthropogenic pressure across the globe (Dudgeon, 2014; Dudgeon et al., 2006; Reid et al., 2019).

1 INTRODUCTION Lakes are a dominant freshwater habitat in Arctic landscapes (Pienitz et al., 2004; Rautio et al., 2011). They are biodiversity hotspots, key sites for biogeochemical cycling and nutrient processing (Vincent et al., 2013), and a resource for Arctic Peoples (Lento, Goedkoop, Christoffersen, et al., 2019; Lento, Goedkoop, Culp, et al., 2019).

1 INTRODUCTION Predation is a near-constant threat for most organisms (Lima & Dill, 1990). Predators serve an important role in ecological systems, regulating the populations of many other species through direct consumption (Murdoch & Oaten, 1975) and fear-based non-consumptive effects (“NCEs;” Wirsing et al., 2021), which can elicit strong responses from prey (Creel, 2018; Shea et al., 2020; Wirsing

1 INTRODUCTION Freshwater ecosystems are particularly vulnerable to anthropogenic global change with higher rates of extinction and population decline compared to other realms (Almond et al., 2020). As low points in the landscape, fresh waters act as sinks where a high diversity of physical, chemical and biological stressors can co-occur.

1. Integral to many ecological models is the notion that dispersal connects populations and communities in disparate locations.
