Summary: Research on the large branchiopod crustacean fauna in the Neotropical Bioregion is still incomplete, with new taxa regularly being discovered and described. This study provides an assortment of notes and records on various Neotropical taxa, along with a checklist listing reported species and new distributional records. The information presented here will aid in future studies, surveys, and conservation efforts in the region.

Summary: The study revealed that taxonomic relatedness is a better predictor of thermal preference and critical thermal limits for large branchiopods in thermally dynamic wetland ecosystems, rather than the environment of origin. Spinicaudatans showed higher tolerance to high temperatures and preferred higher temperatures compared to anostracans, indicating a potential difference in thermal adaptation strategies between the two taxonomic groups.

Summary: Palaeoecology is playing an increasingly important role in conservation biology and restoration ecology by extending ecological observations to centennial and millennial time scales. One potential application is uncovering hidden species in subfossil records, as demonstrated in the case of Riella in southwest Asia. This study highlights the importance of taxonomic identification to reveal hidden biodiversity and improve conservation strategies for vulnerable ecosystems.

Summary: This study measures the methane concentration in the Llanos de Moxos wetlands in northern Bolivia and finds that the daily methane flux in this area is very high, potentially contributing up to 8% of annual methane emissions in the Amazon Basin.

Summary: Temporary Mediterranean wetlands exhibit both intra and interannual variations in environmental conditions, impacting the structure and dynamics of aquatic communities. Chlorophyll-a concentration, Secchi depth, total nitrogen concentration, wetland area, and depth were found to have significant influences on zooplankton community, leading to species replacement patterns. Optima and tolerance of zooplankton species were identified based on their positions within a CCA diagram, enabling the grouping of species along the hydroperiod. Monitoring of zooplankton community and environmental conditions is crucial to assess the potential impacts of anthropogenic activities on these unique and endangered aquatic ecosystems in the future.

Summary: Understanding the diet of the endangered Southern Resident killer whales is crucial for conservation efforts, with findings showing that Chinook salmon is a key prey item year-round, particularly in winter and spring. Other salmon species and non-salmonid fishes also contribute significantly to their diet in winter, highlighting a relatively high species diversity. Increasing the abundance of Chinook salmon stocks in the whales' winter range could be an effective conservation strategy for this population.

Summary: The seasonal flood pulse in Amazonia plays a crucial role in structuring community diversity in floodplain environments. This study examined the impact of seasonal flooding on fruit-feeding butterfly assemblages in different forest types and strata. The results showed that butterfly abundance decreased during the high-water season, especially in várzea forests, but species richness remained similar between seasons in all forest types. The flood pulse only affected butterfly assemblages in várzea forests, highlighting the idiosyncratic responses of butterfly communities to flooding in different forest types.

Summary: Horizontal levees are a nature-based solution for removing nitrogen from municipal wastewater effluent and provide additional benefits. The study found that nitrogen removal was primarily achieved through the consumption of labile organic carbon by heterotrophic denitrifiers. A model was developed to predict long-term nitrogen removal, showing that labile organic carbon can sustain nitrogen removal for several decades.

Summary: Methane emissions from small freshwater ecosystems are a major uncertainty in the global methane budget. The study found that inundation extent and duration, as well as the direction of water level change, are major drivers of methane emissions in seasonally inundated forested wetlands. Modeling the hydrologic regime of these wetlands can lead to more accurate estimation of methane emissions.

Summary: This study compares the waterbird assemblages in natural wetlands and artificial wetlands in Sindh Province, Pakistan. The results show that natural wetlands attract a greater diversity of waterbirds, while artificial wetlands harbor a wider range of resident waterbird species.

Summary: The rediscovery of the moss Drepanocladus lycopodioides in an abandoned sandstone quarry in the Czech Republic may provide potential refugia for endangered fen species. The abandoned waterlogged quarries mimic the key environmental conditions that determine the natural occurrence of D. lycopodioides, which are no longer present in current central-European agricultural landscapes.

Summary: iPSCs from three endangered avian species were developed and characterized as a potential resource for their conservation. These iPSCs showed pluripotency markers, expressed pluripotency-related genes, and differentiated into three germ layers. Despite using the same reprogramming factors, the iPSCs from Japanese ptarmigan displayed different cellular characteristics and contributed to chimeras in chicken embryos. This study provides the first evidence of the potential value of iPSCs as a resource for endangered avian species conservation.

Summary: The trophic niche width of arboreal rats is influenced by temporal variation of food resources, between-individual differences in food-resource rank preferences, and competition. During the wet season, the rats have a wider isotopic niche due to individual specialization, while in the dry season, individual niche widths contract. The population trophic niche width expands via individual specialization in response to ecological opportunity and increased competition in the warm-wet season.

Summary: Environmental productivity and biodiversity are interconnected, with biodiversity often peaking at intermediate levels of productivity. Nutrient enrichment can lead to eutrophication, impacting invertebrates in habitats like California vernal pools. This study showed changes in mesocosm turbidity, chlorophyll-a, and phosphorus levels due to nutrient addition, with increases in small crustacean abundance but no effects on taxonomic richness. Further research is needed on long-term nutrient inputs and their interactions with human activities.

Summary: Plant community assembly is influenced by environmental factors such as hydro-regime, nutrient levels, and thatch accumulation. This study evaluated the responses of algae and plant functional groups to variation in hydro-regime, nutrient addition, and thatch. The results showed that unstable hydroperiods and nutrient addition increased algal cover, while aquatic plant cover was negatively associated with algae and positively associated with terrestrial plant cover. Stable hydro-regime promoted aquatic plant growth, while thatch accumulation promoted terrestrial plant growth. These findings are crucial for wetland conservation and management.
