Factors Influencing the Stocking of Juvenile Pikeperch (Sander lucioperca)

open access: yesFisheries Management and Ecology, Volume 33, Issue 3, Page 425-437, June 2026.
ABSTRACT Predator species of fish play crucial roles in ecosystem balance through top‐down control, a mechanism frequently exploited in biomanipulation to stock predator species. Juvenile pikeperch (Sander lucioperca) were stocked (n = 52,887) in spring 2023 and 2024 and autumn 2023 to compare stocking efficiency between Recirculation Aquaculture ...

Rotifers as models for the biology of aging [PDF]

open access: yesInternational Review of Hydrobiology, 2014
It has been two decades since 1993 when research on the biology of rotifer aging was last reviewed by Enesco. Much has transpired during this time as rotifer biologists have adapted to the “omics” revolution and incorporated these techniques into the experimental analysis of rotifers.

Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

open access: yesDevelopmental Dynamics, Volume 255, Issue 5, Page 503-521, May 2026.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Efecto de la estructuración por macrófitas y por recursos alimentarios en la distribución horizontal de tecamebas y rotíferos en un lago andino patagónico Effect of macrophytes and food resources on the horizontal distribution of testate amoebae and rotifers in an Andean-Patagonian lake

open access: yesRevista Chilena de Historia Natural, 2007
La presencia de macrófitas en la zona litoral lacustre trae aparejada condiciones diferentes con respecto a la zona pelágica, en particular en la disponibilidad de recursos. Por esta razón, las zonas litorales pueden presentar una mayor biodiversidad. En

Rotifera of the Peruvian Andes: New Records and Insights

open access: yesDiversity
The Rotifera fauna of the Peruvian Andes remains significantly understudied, as evidenced by our findings from a limited sampling effort of 18 locations (15 samples from the Cusco region and three samples from Lake Titicaca). We identified 12 Monogononta

Zooplankton biodiversity and community structure vary along spatiotemporal environmental gradients in restored peridunal ponds

open access: yesJournal of Limnology, 2015
Zooplankton assemblages in neighboring ponds can show important spatial and temporal heterogeneity. Disentangling the influence of regional versus local factors, and of deterministic versus stochastic processes has been recently highlighted in the ...

Environmental Changes Produced by Cold-Water Outlets from Three Arkansas Reservoirs [PDF]

open access: yes, 1971
Water qualities of two natural streams (Buffalo and Kings Rivers), one new coId-tailwater (Beaver), and two old coId-tailwaters (Norfork and Bull Shoals) in northwestern Arkansas were studied from July 1965 through October 1968.

Direction and Progression of Thermal Acclimation Effects on Ciliated Protist Populations Both Depend on Direction of Thermal Change

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Previous research has demonstrated that acclimation can have positive or negative effects on population growth rates in variable thermal environments, depending on the amount of time acclimation takes. A clear picture of the timescale of acclimation may help identify the consequences of various frequencies of thermal fluctuations for population ...

UV-irradiated rotifers for the maintenance of gnotobiotic zebrafish larvae

open access: yesmSphere
Host-associated microbial communities profoundly impact the health of humans and other animals. Zebrafish have proven to be a useful model for uncovering mechanisms of host-microbe interactions, but the difficulty of maintaining germ-free or gnotobiotic ...
