The phototrophic epipelon has been suggested to play an important role in ecosystems, especially those with shallow depths; however, only a few studies have investigated this function. Nutrient availability has been shown to be a determining factor for autotrophic interactions and can potentially interfere with the food web, as eutrophication. Thus...

Physical space, defined by its volume and shape, is considered a resource for plant growth, as a plant can be limited by physical space even when other resources (e.g., light, water and nutrients) are unlimited. However, the effect of physical space limitation on intraspecific competition of plants, especially floating plants, is not well understoo...

Few studies have assessed whether patterns of resource partitioning among sympatric marine predators vary between different habitats. This type of data is important for understanding food web functioning as well as for supporting an ecosystem-based fisheries management plan. In this study, we used δ13C and δ15N stable isotope analysis to assess the...

Although several studies explain the trophic cascade in water systems, we lack knowledge about top-down–bottom-up effects on phytoplankton from eutrophic lakes. In this study, we tested the importance of trophic cascades on phytoplankton structure, predicting that environmental variations are the main drivers. We performed a monthly sampling during...

The existence of a temperature gradient across latitudes is crucial to explain the patterns presented in the early life-history characteristics of marine fish species over large geographical areas. Hence, the aim of the present work was to analyse the temperature-related pattern in the early life-history events and characteristics of the common sol...

Brackish lagoons are vulnerable aquatic environments that host specifically adapted fish species, as well as marine species on a temporary basis. We used long-term passive fishing gear data, to investigate how meteorological factors (i.e., wind and rain) affected resident and marine fish movement between inner and outer habitats in a Northern Medit...

Cryoconite holes (water-filled reservoirs) are considered ecologically simple ecosystems but represent biological hotspots of biodiversity on glaciers. In order to check for fine-scale spatial distribution of metazoans on the bottom of the holes, in this study, we analysed three groups of grazing invertebrates as a model: tardigrades, rotifers, and...

Functional-approach studies are currently increasing in ecology. However, for zooplankton communities, studies are mostly concentrated in marine environments. This study provides a systematic review to reveal the trends and gaps in scientific literature regarding zooplankton functional-approach in continental aquatic environments, including its mai...

Parasites potentially have important roles in aquatic ecosystems, although relatively little is known about their contributions to the complexity of food web structure. In this study, stable carbon and nitrogen isotope analyses (δ13C and δ15N) were applied for fish host–parasite systems in a shallow swamp–lake ecosystem to assess the validity of st...

The snail Nereina punctulata has been observed performing amphidromous migrations (salt to freshwater migration, post-larval settlement) in the Caribbean, with small- and medium-sized snails achieving maximum fitness at the mid- and high altitudes, but they may be restricted by energy stores. Large snails show no difference in fitness across altitu...
