Mapping the structure of mixed seagrass meadows in the Mexican Caribbean
Frontiers in Marine Science, 2022 The physical and ecological importance of seagrass meadows in coastal processes is widely recognized, and the development of tools facilitating characterization of their structure and distribution is important for improving our understanding of these ...

Global Ecology and Biogeography, Volume 32, Issue 6, Page 976-986, June 2023., 2023 Abstract Aim The global vertical depth distribution of seagrass species remains poorly understood. Locally, the abundance and distribution of seagrasses is determined by light penetration, but at global levels each seagrass species has very distinct maximum distributional depth ranges, indicating that plant‐associated traits must also influence their ...

Seagrass ecosystem multifunctionality under the rise of a flagship marine megaherbivore
Global Change Biology, Volume 29, Issue 1, Page 215-230, January 2023., 2023 Three scenarios of megaherbivore grazing intensity can be observed in tropical seagrass ecosystems with green turtles as megaherbivores across the world (Figure a). The turtle's ecological role is rapidly unfolding in numerous foraging areas where populations are recovering through conservation after centuries of decline, with an increase in recorded ...

Ecosphere, Volume 13, Issue 11, November 2022., 2022 Abstract Populations of green turtles (Chelonia mydas), a megaherbivore that consumes seagrasses via cultivation grazing, are recovering worldwide. Information on plant‐mediated effects on herbivore foraging behavior is critical to understanding plant–herbivore interactions and sustainability of grazing as ecosystems continue to change.

Potential role of submerged macrophytes for oxic methane production in aquatic ecosystems
Limnology and Oceanography, Volume 67, Issue S2, Page S76-S88, November 2022., 2022 Abstract Methane (CH4) from aquatic ecosystems contributes to about half of total global CH4 emissions to the atmosphere. Until recently, aquatic biogenic CH4 production was exclusively attributed to methanogenic archaea living under anoxic or suboxic conditions in sediments, bottom waters, and wetlands.

Ecological Indicators, 2023 Seagrasses are long-lived, clonal plants that can integrate fluctuations in environmental conditions over a range of temporal scales, from days to years, and can act as barometers of coastal change.

Two temperate seagrass meadows are negligible sources of methane and nitrous oxide
Limnology and Oceanography, Volume 67, Issue S2, Page S193-S207, November 2022., 2022 Abstract Seagrasses are globally important ecosystems that can help mitigate climate change by sequestering carbon (C). The net impact seagrass meadows have on the climate, however, also depends on methane (CH4) and nitrous oxide (N2O) fluxes. By not accounting for CH4 and N2O fluxes, we may be overestimating or underestimating the true C sequestration

Diversity and Distributions, Volume 28, Issue 11, Page 2272-2285, November 2022., 2022 Abstract Aim Conservation efforts have traditionally addressed the threat of biodiversity loss by prioritizing regions and habitats with high endemic species richness. However, species‐poor habitats often harbour distinct, valuable and/or functionally unique species that contribute to regional diversity.

Species Traits and Geomorphic Setting as Drivers of Global Soil Carbon Stocks in Seagrass Meadows
Global Biogeochemical Cycles, Volume 36, Issue 10, October 2022., 2022 Abstract Our knowledge of the factors that can influence the stock of organic carbon (OC) that is stored in the soil of seagrass meadows is evolving, and several causal effects have been used to explain the variation of stocks observed at local to national scales. To gain a global‐scale appreciation of the drivers that cause variation in soil OC stocks,
