Possible covariates that could be predictors of abundance were depth of the measurements, date, site effect (UPJP versus UPR), type of collection gear or net effect (quadrat, aquarium net, small plankton net
, and large plankton net
Amoebae testate associated with aquatic macrophytes samples were obtained by dragging graduate bucket (13 L) in the rooted marginal vegetation (five times), totaling 65 L, and then filtered in a 20 [micro]m-mesh plankton net
Ctenophores collected by gentle plankton net
tows were transported to the laboratory within 12 hours.
We filtered 50 L of water per sample through a plankton net
To compare the microcrustacean diversity in different freshwater environments, five ponds were chosen and plankton samples were taken with a plankton net
(500 mL of fresh water, and 25 g of sediment collected from each site).
5-m mouth diameter, conical plankton net
(see Peebles et al.
Plankton samples were collected the d of each feeding from a local pond with a student plankton net
(2 mm mesh, BioQuip), and consisted primarily of cladocerans.
A standard plankton net
with 40 um mesh size was used and the samples were preserved in a 4% neutral formaldehyde solution.
The larvae of Culex quinquefasciatus Say 1823 (Diptera: Culicidae) were collected using plankton net
(200 [micro]m mesh size) from sewage drains in and around Ballygunge Science College, Kolkata.
25t plankton net
below the surface 1 to 3 feet deep.
Under the guidance of Fucile and three volunteers from the National Oceanic and Atmospheric Administration, each boy researched and wrote an essay on an oceanographic topic, made a plankton net
, and collected water samples from a nearby lake.
While walking the length of the dock four times (a total of 133 m), we towed a plankton net
with an opening diameter of 32 cm and a mesh size of 80 [micro]m.
