\begin{abstract}
Seagrasses and mangroves are crucial sources of atmospheric methane
(CH\textsubscript{4}) from coastal areas. To study the dynamics of
CH\textsubscript{4} cycling at subtropical seagrass and mangrove, we
studied diurnal CH\textsubscript{4} emissions at the sea-air and
sediment-water interfaces and related environmental parameters in August
2019 at lagoonal estuaries of southern Texas, USA, northwest coast of
the Gulf of Mexico. Although seagrass meadows and mangroves locate at
closely connected subtropical estuaries, they displayed distinct
mechanisms in CH\textsubscript{4} cycling. Dissolved CH\textsubscript{4}
concentration at the seagrass meadow decreased in the daytime and
increased overnight, expressing a tight relationship with photosynthesis
and respiration of seagrass. Plant mediation of seagrass played a
crucial role in CH\textsubscript{4} production, oxidation, and transport
from sediment to water column. In comparison, the diel variation of
dissolved CH\textsubscript{4} concentration at the mangrove creek was
controlled by tidal progression. The maximum CH\textsubscript{4} level
occurred during ebb due to the export of CH\textsubscript{4} from inside
the mangrove to the outside bay. Tidal pumping and tidal inundation were
essential conduits for dissolved CH\textsubscript{4} exchange between
water and porewater. In both areas, sea-air CH\textsubscript{4} fluxes
were significantly affected by wind speeds, which hid related diurnal
variations caused by physiological or tidal cycles. Our study also
revealed a more significant contribution from seagrass to the local
CH\textsubscript{4} budget than from mangroves, indicating
CH\textsubscript{4} released from subtropical seagrass needs further
investigation.%
