“…However, only air temperature was used for analysis in this study, due to its high correlation with water temperature measured in situ and scientific support from previous research. Among the articles we examined, 6 publications reported water temperatures measured in situ (Lee et al 2005, 2006, Park et al 2011, Zhang et al 2015, Kim et al 2016, Suonan et al 2017. When on-site water measurements were compared with extracted air and water temperatures, half of the sites showed higher correlations with extracted air temperatures while the other half showed higher correlations with extracted water temperatures (data not shown).…”

“…However, high spatial and temporal variation within the group were observed. Peak biomass timing from the same site but from a different tidal zonation could differ as much as 87 to 95 d (Kim et al 2016, Suonan et al 2017). Even at the same location, observations from 2 consecutive years resulted in peak timing differences of 57 d in an undisturbed condition (Kaldy 2006) and up to 192 d when disturbed; biomass peaked in March− April in an undisturbed year and in late October in the year disturbed by clamming activity (Park et al 2011).…”

Large-scale analysis along latitude or temperature gradients can be an effective method for exploring the potential roles of light and temperature in controlling seagrass phenology. In this study, we investigated effects of latitude and temperature on seagrass biomass and reproductive seasonality. Zostera japonica is an intertidal seagrass with a wide latitudinal distribution expanding from tropical to temperate zones in its native range in Asia, with an additional non-native distribution in North America. We collated available data on phenological traits (timings of peak biomass or reproduction, durations of biomass growth and reproductive season, and maximum biomass or reproductive ratio) from publications and our own observations. Traits were compared among geographic groups: Asia-tropical, Asia-temperate, and North America-temperate. We further examined relationships between traits and latitude and temperature for 3 population groups: Asian, North American, and all populations. Our analysis revealed significant variation among geographic groups in maximum biomass, peak reproductive timing, and maximum reproductive ratio, but not in other traits. Maximum biomass and peak reproductive timing for Asian and all populations were significantly correlated with latitude and temperature. Maximum biomass was highest at mid-latitudes or intermediate temperatures and decreased toward distribution range limits, and peak reproductive timing occurred later in the year at higher latitudes or cooler sites. North American populations showed shorter growth durations and greater reproductive ratios at higher latitude. Different responses observed for North American populations may reflect effects of introduction. Our study demonstrates potential variation among geographic regions and between native and non-native populations.

“…Berdasarkan hasil uji nilai b (kemiringan), menunjukkan bahwa tegakan spesies lamun C. rotundata memiliki pertumbuhan daun yang lebih cepat pada zona intertidal bagian atas dan bagian tengah, dibandingkan pada tegakan lamun spesies yang sama pada zona intertidal bagian bawah (Tabel 7). Pertumbuhan yang lebih cepat pada zona intertidal di bagian atas dan tengah juga telah dilaporkan oleh Kim et al (2016) pada spesies lamun Zostera japonica. Pertumbuhan yang cepat pada zona intertidal bagian atas dan tengah, sangat berkaitan dengan kemampuan adaptasi dan kondisi lingkungan yang mendukung.…”

Cymodocea rotundata is a seagrass species that occupy habitats in the intertidal zone. The ability of this species to occupy the intertidal zone is thought to be related to its particular morphological adaptations in response to fluctuations in local aquatic environmental conditions. This study aims to describe habitat conditions, distribution related to density, morphological differences, and growth among C. rotundata seagrass stands in the upper, middle, and lower intertidal zones of Yankarwar Beach, Manokwari, West Papua. Transects and quadrats methods were used to collect seagrass samples, so information on their distribution and density could be obtained. The seagrass samples collected were also analyzed (counted and measured) for their morphological characters including the number of leaves, leaf length, leaf width, horizontal sheath internode length, root length, stand weight, leaf weight, rhizome weight, and root weight. Seagrass growth was obtained by marking the leaves and observing them for 10 days. The results of this study indicate that the conditions of the physicochemical parameters of the intertidal waters are still suitable for the growth of this seagrass species. The highest density was found in the upper intertidal zone (3,161.73 stands.m-2) and followed by the middle intertidal zone (962.04 stands.m-2). Although most of the morphological characters of seagrasses and seagrass parts were relatively the same between the three intertidal zones, larger leaf widths and lengths of horizontal rhizome internodes were found in stands in the two upper intertidal zones. Differences in growth as reflected by the increase in leaf length and dry leaf weight also showed greater values in the upper and middle intertidal zones. This condition shows the adaptability of this seagrass species to variations in environmental parameter conditions in the middle and upper intertidal zone. In addition, the results of this study indicate the presence of C. rotundata, especially in the intertidal aquatic environment which has an important ecological role, including as a substrate stabilizer. Therefore, this vegetation conservation effort is very important. Keywords: intertidal zone, morphological adaptation, seagrass growth

“…Several studies have shown the sensitivity of seagrasses to desiccation stress (van der Heide et al 2010, Kim et al 2016, Suykerbuy, Govers, et al 2016 and, even though Z. noltei possesses physiological adaptations to reduce tissue water loss and keep appropriate photosynthesis levels during emersion periods (Larkum et al 2006, Folmer et al 2016, desiccation stress might still be a limit to its colonization of higher intertidal levels (van der Heide et al 2010, Folmer et al 2016. Additionally, in higher exposed bed levels, Z. noltei is submitted to longer and wider range of temperature changes, another relevant factor for the seagrass performance (Marba et al 1996).…”

Ecosystem engineering effects of dominant species on habitats and consequently on other species are likely to propagate through time at longer distance than the close neighbourhood. Such effects are important to disentangle from short-term biotic effects, especially in biological invasions, as engineering can explain changes in invasion rates over the course of the invasion. We assessed the contribution and spatial dynamics of ecosystem engineering effects of a strong invader, the cordgrass Spartina anglica, on Zostera noltei, a foundation seagrass species of muddy intertidal systems in Europe. Z. noltei transplants were grown at different positions along transects crossing intact S. anglica patches, cut patches and nearby bare sediment on tidal flats in the Bay of Arcachon (France), in order to separate ecosystem engineering effects from short-term biotic effects and evaluate their likely spatial propagation. Bed altimetry, sediment redox potential and granulometry were measured in all treatments. Within Spartina patches, we found strong negative ecosystem engineering effects of the cordgrass on the seagrass associated with increased sediment elevation and relative fine sediment content. Up to 2 m outside the patch, we found significant negative ecosystem engineering effects and positive short-term biotic effects, but they were weak and counterbalanced each other. We conclude that S. anglica can transform a marine muddy intertidal habitat into a drier and more oxidized terrestrial habitat, no longer suitable for the seagrass. Although these effects may propagate at several metres from a patch, they appeared to be too weak to likely affect the seagrass at the scale of a whole bay.
