Younger Dryas to earliest Holocene mega‐landslides (>10 km2) in the eastern Fish Lake Plateau of central Utah required unusually wet conditions to drive movement. The sediment from abundant small lakes, ponds and especially fens that formed in swales between hummocks on the landslide surfaces are excellent archives of past climate. An integrated geophysical, geochemical and micro‐palaeontological investigation characterized fen deposits, determining the timing of mass movement and establishing the subsequent climate history of the region. High‐resolution P‐(compressional) wave surveys of fen deposits were conducted to image fen‐landslide contacts. Past climate states were assessed through loss on ignition, pollen and diatom abundances. Diatoms, in particular, record large variations in precipitation as the present‐day wetland switched from fen (intermittent standing water) to pond states in response to variable precipitation. One core was analysed for detailed climate proxies. A wet episode (pond) prevailed from 11.5 to 10 ka after which the climate became much drier (fen) until 6 ka due to weakening of the North American Monsoon. After 2.5–2.0 ka, reduced insolation produced cooler summers and wet winters (pond). Only recently (<500 years) has a fen re‐emerged based on direct observation and the disappearance of diatoms that require standing water. 14C ages of basal sediment from four cores show two episodes of movement: 12.8–12.5 and 10.5 ka. The earlier ages indicate that Younger Dryas high effective precipitation caused mass wasting. Later, during early Holocene times, colder winters followed by warmer summers and vigorous monsoons drove movement as rapid spring snow‐melt was followed by wet summers. In broad terms, this work highlights variable climate conditions that can drive mass movement, as well as the sensitivity of diatom records in fens to effective precipitation.

“…The algal flora of the lagoon did not have rich species variation, except some dominant species, because of the eutrophic conditions. The phytoplankton species richness in Bafa Lake [30], Homa Lagoon [34], Akyatan and Tuzla lagoons [32] were recorded in low numbers like Kamil Abduş Lagoon and the phytoplankton composition showed similarity.…”

“…In lagoons all over the world, Bacillariophyta, Dinophyta, Chlorophyta and Cyanobacteria divisions were usually found to be the most important groups [6,29]. There is still insufficient research on phytoplankton composition in lagoons located in different regions of Turkey and the whole world [2,3,[30][31][32][33][34]. Bacillariophyta was determined the richest group in terms of species numbers as Bafa [30], Chilika [29], Liman [3], Paradeniz [33], Homa [34], Lesina [6], Akyatan and Tuzla lagoons [32].…”

“…It was expressed that these dinoflagellates are presented from oligotrophic to eutrophic waters in a wide range and Prorocentrum micans and P. lima of dinoflagellates were recorded as euryhaline species and tolerated salinity changes [36,37]. Similarly P. micans had peaked in August and November in Lake Bafa [30]. In addition, P. bipes and P. micans of Dinophyta division were stated as dominant species in Küçükçekmece Lagoon by Yilmaz [2] and Caroppo et al [6] reported blooms that Prorocentrum cordatum was made in Lesina Lagoon.…”

In the present study, the water quality and pollution status of Kamil Abduş Lagoon (Tuzla Lake), which is located in Istanbul Metropolitan area, were investigated by determining the phytoplankton composition, some physicochemical parameters, and nutrient concentrations. Water samples were collected at 3 sampling sites between February 2016 and January 2017 on a monthly basis. A total of 32 taxa, belonging to Bacillariophyta (12), Charophyta (1), Chlorophyta (4), Cryptophyta (1), Cyanobacteria (5), Euglenozoa (5) and Miozoa (4) divisions were identified. Both freshwater and marine species were recorded in the study area. The presence of mesotrophic and eutrophic species of phytoplankton, high concentrations of chlorophyll-a and nutrients indicated that the trophic level of the lake is near to eutrophic. Water quality parameters studied in the current research were investigated to evaluate the input data significance using Artificial Neural Network analysis, specifically to ensure the limitation of regression analysis overfitting. Due to the fact that the lagoon is under threat by pollution it needs to be urgently protected. Therefore, detailed studies on phytoplankton including physicochemical parameters and nutrients have to be carried out in order to select appropriate management routes for improving the water quality in the lagoon.

Long‐term biodiversity monitoring is crucial for freshwater ecosystems as it enables the detection of even subtle changes and biodiversity trends, guiding conservation efforts and ensuring the sustainability of these vital habitats. Despite becoming more commonly considered in the field of freshwater ecology and biological invasions, studies using long‐term time series from Türkiye's freshwater resources have remained scarce. To assess the availability of data and ultimately present a baseline for future efforts, we combined published museum records and samples from recent field studies from the highly anthropogenically‐altered Lake Bafa in Western Anatolia covering the period 1958–2019. Lake Bafa has a very diverse aquatic ecosystem, providing habitat for both freshwater and saltwater species, and is one of the allottees in Türkiye's inland fish production. In the current study, we investigated how fish populations in Lake Bafa were affected by environmental changes and examined changes in taxonomic and functional diversity of non‐native species over time. The analyses revealed—concomitant to an increase in native marine and freshwater species richness—an increase in non‐native species richness over time. Non‐native species did not interfere with native species' niche space, whereas applied models indicate that in this highly altered ecosystem, foremost temperature and salinity shaped the fish community over time, limiting the impacts of non‐native species. These results have implications for the fishery of the lake, which includes highly valuable catadromous fish species, highlighting the value and importance of collecting long‐term data in Türkiye to better understand both invasion dynamics and changes in the naturality of Turkish ecosystems. These findings further underline the importance of long‐term data to create new management strategies for the lake and to start restoration processes, thus improving fisheries management.
