“…Regarding Culicoides, its presence across a larger area across this high-energy shore is notable since immatures usually inhabit low energy environments, such as tidal pools [68][69][70]. Most of the macrobenthic species recorded in this study are commonly found in other areas of the Brazilian coast [16,60,71]. However, the prevalence of larvae of Culicoides sp.…”

Rainfall Influences the Patterns of Diversity and Species Distribution in Sandy Beaches of the Amazon Coast

et al. 2023

The Amazon region is one of the Earth’s hotspots of biodiversity and has a pivotal role in climate regulation. Yet, little is known about its coastal biodiversity. Here, we performed the first assessment of macrobenthic diversity and ecological patterns of sandy beaches north of the Amazon River delta, the world’s largest freshwater input into the oceans. By assessing spatial and temporal changes in the soft-bottom biodiversity and environmental variables of three beaches (Goiabal, Nazaré, and Sumaúma) in the northernmost stretch of the Brazilian coast, we found low richness (14 taxa, overall; Goiabal: 3.27 ± 1.78; Nazaré: 2.34 ± 1.29; Sumaúma: 2 ± 0.67) and diversity (Goiabal: 0.72 ± 0.52; Nazaré: 0.62 ± 0.46; Sumaúma: 0.55 ± 0.39) across 2949 individuals with great dominance of estuarine species (notably Nephthys fluviatis and Sphaeromopsis mourei). Abundance was higher during rainy periods, and the same pattern was observed for richness and diversity in comparison to transitional periods, at least on Nazaré Beach. Environmental heterogeneity was reduced during rainy periods, resulting in a higher abundance of dominant species and lower beta diversity. Most species presented aggregated distribution at the upper intertidal zone, and changes in macrobenthic assemblages were linked to variations in rainfall and organic matter content in the sediment. Given the ecological uniqueness and the severe erosional process affecting the northern coast of the Amazon region, our results provide essential baseline knowledge to better understand the patterns and processes influencing its understudied biodiversity. We advocate that further studies expand our findings to support the conservation of this region.

“…Indeed, this species is a dominant taxa in the benthic assemblages of estuarine systems of the Amazon [18,57]. Similarly, other dominant species on Nazaré, Goiabal, and Samaúma Beaches, such as the isopod, Sphaeromopsis mourei, and larvae of midges, Culicoides sp., are also with estuarine areas and freshwater environments [58][59][60].…”

“…From an ocean perspective, there are expected changes in oceanic-climatic drivers affecting the coastline by increasing wave energy, erosion, sediment transport and sea level rise, including a reduction in the intertidal range of some shores (Herring and others, 2018). From an inland perspective, increasing rainfall will disturb sediment transport and increase the input of nutrients, contaminants and pollutants from terrestrial and freshwater environments to coastal habitats (Lana and others, 2018) The cumulative effects of climate change and other anthropogenic influences will continue to affect biodiversity, ecosystem services and environmental health. Those continuous multiple stressors, according to the One Health concept of the World Health Organization, will influence human well-being and health (Fleming and others, 2019).…”

“…Changes in wave dynamics and the increasing frequency of extreme weather events also change sediment composition (Masselink and others, 2016) and larval transport to the shore (Mazzuco and others, 2015). In addition, increasing extreme rainfall events in the tropical and subtropical areas influence near-coast salinity and sediment transport as well as the input of nutrients, pollutants and contaminants from terrestrial and freshwater environments (Lana and others, 2018). The cumulative impacts and influence of such stressors can be seen from organisms to communities, leading to the loss of biodiversity and changes in ecosystem functioning in coastal areas (O' Gorman and others, 2012;Ellis and others, 2017), with impacts on ecosystem services, as well as commercial, recreational and aesthetic values.…”

The Second World Ocean Assessment

2021

The past year has presented unprecedented challenges. The coronavirus disease (COVID-19) pandemic has disrupted lives and livelihoods and exposed our societies' fragility. Sadly, the pandemic is not the only crisis that humanity faces. Climate change and biodiversity loss continue unabated, threatening sustainable development and our viability as a species. These challenges are particularly evident when we look at the state of our planet's life support system, the ocean.In 2015, the first World Ocean Assessment warned that many areas of the ocean had been seriously degraded, the greatest threat to the ocean being the failure to deal with the many pressures caused by human activities. The message in the second World Ocean Assessment is that the situation has not improved, with the many benefits that the ocean provides at risk. The Assessment advises that, to ensure sustainability, we must work together to improve integrated ocean management, including through joint research, capacity development and the sharing of data, information and technology.The ocean plays a crucial role in the achievement of the Sustainable Development Goals and the livelihoods of billions of people. We urgently need to change how we interact with it. The forthcoming United Nations Decade of Ocean Science for Sustainable Development and the United Nations Decade on Ecosystem Restoration provide opportunities for us to understand more and to reverse the damage that has already been done. The information in the second Assessment can assist in this process, as well as inform relevant intergovernmental conferences scheduled for 2021.I urge leaders and all stakeholders to heed the warnings in the Assessment as we work to conserve and sustainably manage our planet's marine environment. Let us foster not only a green but also a blue recovery from the COVID-19 pandemic.

In this study, we examined the relationship between sea surface temperature (SST) and phytoplankton abundance in coastal regions of the Brazilian South Atlantic: São Paulo, Paraná, and Santa Catarina, and the Protection Area of Southern right whales (Eubalaena australis) in Santa Catarina (APA), a conservation zone established along 130 km of coastline. Using SST and chlorophyll‐a (Chl‐a) data from 2002 to 2023, we found significant differences in SST between the regions, with São Paulo having the highest SST, followed by Paraná and Santa Catarina. All locations showed a consistent increase in SST over the years, with North Santa Catarina, APA and São Paulo experiencing the lowest rate of increase. Correlation analyses between SST and Chl‐a revealed a stronger inverse relationship in North Santa Catarina and APA, indicating an increased response of Chl‐a to SST variations in this region. The presence of protected area appears to play an essential role in reducing the negative impacts of increasing SST. Specifically, while there is a wealth of research on the consequences of global warming on diverse coastal and oceanic areas, heterogeneity among different settings persists and the causes for this necessitating attention. Our findings have implications for both localized scientific approaches and broader climate policies, emphasizing the importance of considering coastal ecosystem resilience to climate change in future conservation and adaptation strategies.
