“…Over the last 30 years, Chini Lake and its catchment have been experiencing continuing development, including logging and agricultural development that started in the 1970s (Sharip & Jusoh, ). Construction of weirs to support tourism development has its consequences in changing the natural behaviour of the river–lake, increasing eutrophication and altering macrophyte dominance (Sharip, Schooler, Hipsey, & Hobbs, ; Sharip, Zaki, & Zakaria, ). Conversion of land for logging and agriculture has continued in areas within the Chini Lake catchment (Idris, ; Sujaul, Ismail, Barzani, Ekhwan, & Sahibin, ), which are activities normally associated with ecosystem degradation, including erosion and pollution of water resources.…”

“…Ecological changes have been reported, including construction of a weir on the Chini River in 1995, infestation of a non‐native species and continuing alteration of land uses in the catchment (Idris, ; Sharip et al., ). Altering the natural flow of the river with the establishment of a weir was reported to have altered the flooding and water‐level fluctuation patterns (Sharip et al., ) and nutrient dynamics, with subsequent impacts on the ecological communities (i.e., plankton; fish; aquatic plants). The Chini Lake catchment is inhabited by aboriginal communities from the Jakun tribe (known as Orang Asli) and other local communities from eight main settlements (Figure ).…”

Despite being designated the first UNESCO Biosphere Reserve in Malaysia, the Chini Lake Basin experiences continuing management challenges attributable to existing sectoral management practices and differences in demands of multiple stakeholders.Accordingly, a socio-economic survey and stakeholder consultative process were undertaken, involving relevant stakeholders in the lake basin. The consultative process involved: (a) identification and prioritization of relevant stakeholders; (b) assessment of their socio-economic activities and perceptions; (c) organization of focus group discussions between basin stakeholders; and (d) development of management recommendations in collaboration with stakeholders. The results of this study indicated the local community's way of living has changed from traditional occupations to a wage economy. Overlapping functions and lack of communication were among the major identified challenges facing by Chini Lake. Multiple strategies were proposed to promote environmental protection and good governance of Chini Lake, including formation of special area plans and strengthening institutional arrangements to sustainably manage the Chini Lake catchment. An effective authority also is necessary to improve communication and coordination of programmes by the various basin agencies and communities.

This continued changing of land use with the catchment may affect the local communities dependent on the lake and the forest for their livelihoods, as well as altering other biological communities.Subsistence living, such as fishing and forest hunting, is important for aboriginal communities and highlights their dependence on the lake and surrounding forests remaining intact and, subsequently, the

“…It is native to tropical and subtropical South America and the West Indies (Siti-Munirah and Chew, 2010). However, at present, the plant is recorded from outside its natural range in Asia; India (Anon, 2014;Shaji, 2020), andPeninsular Malaysia (Siti-Munirah andChew, 2010;Sharip et al, 2014), indicating its potential to expand the range. However, up to date, there are no records of its occurrence in natural ecosystems in Sri Lanka.…”

Highlights• Early detection and rapid response is the most cost-effective method to minimize the damage caused by AIS.• We report the occurrence and establishment of C. furcata, as a potential AIS in the natural water bodies in the wet zone.• The percentage cover and type of population are associated with the rate of water flow.• Still to moderate flow is the most suitable condition for the establishment and growth of C. furcata.• The study highlights the risk associated with C. furcata and the importance of initiating steps to eradicate it.

“…Aquatic macrophytes have high demands for biogenic silica (Schoelynck et al, 2010), and so compete with diatoms for this silica, leading to a period of resource limitation in this autochthonous phase. The seasonal increase in macrophyte coverage (e.g., Cabomba and N. nucifera) at Tasik Chini is also decreasing light availability, leading to a decline in (benthic) diatom populations (Sharip et al, 2014). The high abundance of cryptophytes (alloxanthin) coincident with highest aquatic plant development, accounts for the switch from mostly autotrophic (fucoxanthin, lutein) to heterotrophic production during the second bloom period (Figure 2) impacting on the availability of carbon and nutrients downstream under the RCC, most clearly evidenced with increased changes in the C/N ratio and lower apparent molecular weight of humic substances (Figure 2N).…”

Inland waters are highways of carbon and nutrient flows between the land and ocean. Aquatic environments integrate multiple sources and processes over space and time that influence ecosystem functionality. The complexity of these systems and their multiple interactions with the surrounding environment are conceptualised, but often lack empirical scrutiny that allows further understanding of how inland waters mobilise, transport, and utilise carbon and nutrients. This is particularly evident in tropical waters. Here, we apply advanced geochemical analyses of dissolved organic matter (DOM) composition in conjunction with algal pigment biomarkers, to determine the seasonal variability of organic matter production, processing and export for a tropical, floodpulse wetland, Tasik Chini (Malaysia). We identify two phases in the hydrological cycle: Phase 1 signifying a transition from the wet season with high suspended sediment and dissolved organic carbon concentrations. DOM is composed of humic substances, building blocks and lower molecular weight compounds. Towards the end this phase then are periods of increased water clarity and algal productivity. This is followed by Phase 2, which has a greater contribution of autochthonous DOM, composed of proteinaceous material, concomitant with lower dissolved nutrient concentrations, increased mixotrophic algae and emergent vegetation. Based on this framework, we highlight the role of such tropical wetland lakes as hydrological “bottlenecks,” through a lentic/lotic switch that shifts aquatic transport of carbon and nutrients from lateral river continuum supply to flood pulses. We highlight the need to consider inherent biases of spatial and temporal scaling when examining freshwater ecosystems along the land-ocean aquatic continuum.
