Graphical Abstract
Different microbial functioning in natural versus man-made Mediterranean coastal lagoons in relation to season
Coastal marsh lagoons are of high ecological relevance playing a key role in the carbon cycle but are threatened to disappear due to global change effects. Restoration practices can counteract this process.

Metacommunity resilience against simulated gradients of wildfire: disturbance intensity and species dispersal ability determine landscape recover capacity
Disturbances, such as wildfires, are one of the main drivers of biodiversity dynamics, and their frequency and intensity are expected to increase due to global change.

Cladocerans - Font: Wikipedia
Diel changes in vertical and horizontal distribution of cladocerans in two deep lakes during early and late summer
Temporal and spatial heterogeneity in the distribution of cladocerans in lakes could be caused by abiotic (wind, water currents) and biotic factors (reproduction, food resources, predation).

Effects of high nitrate input in the denitrification-DNRA activities in the sediment of a constructed wetland under varying C/N ratios
In constructed wetlands (CW), denitrification usually accounts for >60% of nitrogen removal and is supposedly affected by the inflow water and the wetland management practices.

Limited effect of radial oxygen loss on ammonia oxidizers in Typha angustifolia root hairs
The benefits of plant–microbe interactions have been exploited extensively for nutrient removal. Radial oxygen loss in aquatic macrophytes potentially promotes nitrification and accelerates nitrogen removal through coupled nitrification–denitrification process.

Antioxidant system status in threatened native fish Barbus meridionalis from the Osor River (Iberian Peninsula): I. Characterization and II. In vitro Zn assays
The evaluation of antioxidant system capacity is important in aquatic toxicology. It was aimed to characterize the liver antioxidant enzymes (SOD, CAT, GPX, GR, and GST) and to test the in vitro Zn effect (200 and 400 ZnSO4 μg/L) in native fish Barbus meridionalis obtained from the Osor River (NE, Spain) influenced by Zn contamination.

Alien fish in Neotropical reservoirs: Assessing multiple hypotheses in invasion biology
Invasive alien species (IAS) are one of the main components of global ecological change, the second known cause of animal extinctions, and very costly in terms of ecosystem services. IAS and damming are two of the most impacting alterations in freshwater ecosystems. Understanding the processes that govern biological invasions in these habitats is of enormous conceptual and practical importance.

When a freshwater invader meets the estuary: the peacock bass and fish assemblages in the São João River, Brazil
Peacock basses (Cichla spp.) are native to the Amazon basin but introduced to different parts of the world. Almost thirty years ago, Cichla kelberi was introduced in an impoundment of the São João River, a coastal system in southeastern Brazil.

The role of connectivity in the interplay between climate change and the spread of alien fish in a large Mediterranean river
Understanding how global change and connectivity will jointly modify the distribution of riverine species is crucial for conservation biology and environmental management. However, little is known about the interaction between climate change and fragmentation and how movement barriers might impede native species from adjusting their distributions vs. limit the further spread of alien species.

Addressing trait selection patterns in temporary ponds in response to wildfire disturbance and seasonal succession
Mediterranean ecosystems are increasingly threatened by disturbances such as wildfires. These disturbances are expected to shift the selective pressures that determine trait‐dependent community assembly.

Captive breeding conditions decrease metabolic rates and alter morphological traits in the endangered Spanish toothcarp Aphanius iberus
Physiological features of species can determine the resilience and adaptation of organisms to the environment. Swimming capacity and metabolic traits are key factors for fish survival, mating and predator‐prey interactions.

Organization of Squamata (Reptilia) assemblages in Mediterranean archipelagos
Mediterranean islands have complex reptile assemblages, but little is known about the factors that determine their organization. In this study, the structure of assemblages of Squamata was evaluated based on their species richness and two measures of phylogenetic diversity (variability and clustering).
