Anthropogenic impact has largely altered the estuarine environment. Today, Nature-based solutions (NbS) are required to respond challenges such as flooding that affect both human population and ecosystems. Estuarine ecosystems saltmarshes floodplain forests provide valuable services, wetland restoration for flood control is suggested. Recently, flow velocities attenuating effects of juvenile wi...

Coastal habitats are interlinked by ecological connectivity, defined as the exchange of organic matter or organisms between habitats. The degree this connectivity will depend in particular on geometric properties landscape. increasing anthropogenic alterations estuaries therefore raises need to understand how their morphological characteristics influence fluxes We used stable isotopes investiga...

The estuarine wetland buffer zone of the Fuhe river plays an important role in terms improving water quality Baiyangdian lake. In this study, purification effect and microbial community composition during a low-temperature period were investigated (March, 2021). results indicated that pre-sedimentation ecological pond (Pep), subsurface flow (Sfw), aquatic plant (App) exhibited good removal effe...

In closed aquatic environments like ponds or lakes, water bloom caused by eutrophication has severely damaged aquatic ecosystems. Some previous studies suggested that submerged macrophytes contribute to the development of aquatic ecosystems and water purification. Although water purification and lake ecosystem restoration using submerged macrophytes have been greatly studied, their specific mec...

Estuarine ecosystems interconnect freshwater and marine environments, comprise multiple highly dynamic complex microhabitats. The resident microbiota in estuary is influenced by contrasting microenvironmental heterogeneity. However, the bacterial patterns assembly processes different microhabitats of estuarine ecosystem are not well studied. Here, we investigated diversity, functions community ...

در کار اول یک حسگر نوری جدید، بسیار انتخاب پذیر و حساس جهت اندازه گیری یون های نقره در آب بر پایه 2(4-هیدروکسی پنت-3-ان-2-ایلدنامین)فنول (hpyap) ساخته شد. hpyap یک رفتار انتخاب پذیر در مورد یون های نقره دارد، بدین صورت که رنگ زرد کمرنگ محلول hpyap با یون های نقره تغییر رنگی به سمت رنگ زرد-سبز بسیار پررنگ می دهد، که به راحتی با چشم قابل تشخیص می باشد. این حسگر نوری پس از کمپلکس با یون های نقره، ...
