Описание

All 101 lakes included in the dataset are located in the Western Alps. The selection of ponds followed the criteria that they had to be from 0.1 to 147 hectares in surface, from 1.0 to 68.5 meters in maximum depth, from 5 to 10 months per year of ice cover duration, and located close to or above the treeline, from 1556 to 3049 m. Samples of zooplankton were collected over a period of 19 years (2006-2024; 1-52 samples per lake; 17-47 samples per year). Samples were collected using vertical net hauls (from the bottom to the surface) at the deepest point of each lake, with a conical plankton net (30 or 40 cm diameter, 50 μm mesh). After collection, samples were promptly fixed in the field using either 70% ethanol or Lugol’s iodine solution. Abundance estimates were back-transformed to represent the number of individuals per cubic meter of water. At the conclusion of these operations, the entire sample was examined to identify taxa present at very low-density levels, which may have passed unnoticed due to subsampling. The dataset includes 4463 records of the taxa Rotifera, Copepoda, Cladocera.

Методы сбора

Repeated samples of zooplankton were collected from 101 lakes over a period of 19 years (2006-2024; 1-52 samples per lake; 17-47 samples per year). The sampling frequency and duration varied among lakes; some lakes were sampled throughout the entire 19-year period, while others were sampled for shorter periods (ranging from 2 to 18 years), or in some cases, just for one year. Sampling was primarily conducted in late summer (August-October), to capture the late stage of seasonal succession when most zooplankton species reach their biomass peak. Many lakes were sampled multiple times during the ice-free season (2-8 times per year), including early summer, to account for the strong seasonal dynamics of zooplankton communities. Samples were collected using vertical net hauls (from the bottom to the surface) at the deepest point of each lake, with a conical plankton net (30 or 40 cm diameter, 50 μm mesh). After collection, samples were promptly fixed in the field using either 70% ethanol or Lugol’s iodine solution. Zooplankton samples were then concentrated to a known volume, and 3-5 subsamples of volumes ranging from 0.05 to 1 mL were extracted after homogenization using a wide-bore pipette for counting. Abundance estimates were back-transformed to represent the number of individuals per cubic meter of water. At the conclusion of these operations, the entire sample was examined to identify taxa present at very low-density levels, which may have passed unnoticed due to subsampling. If any were found, their density was fixed to a default value of 0.1 individuals per cubic meter of water.

Охват исследования All 101 lakes included in the dataset are located in the Western Alps.
Контроль качества All data, taxonomic identifications, and nomenclature were kept at the highest possible standards for this type of ecological research.

Описание этапа методики:

  1. Animals were sorted and isolated in the laboratory under a dissecting microscope. All isolated individuals were identified using a compound microscope to species level when possible, if not to genus or higher taxonomic level.
