Data from: Density regulation in Northeast Atlantic fish populations: density dependence is stronger in recruitment than in somatic growth

Fabian Zimmermann, Daniel Ricard & Mikko Heino
1. Population regulation is a central concept in ecology, yet in many cases its presence and the underlying mechanisms are difficult to demonstrate. The current paradigm maintains that marine fish populations are predominantly regulated by density-dependent recruitment. 2. While it is known that density-dependent somatic growth can be present too, its general importance is unknown and most practical applications neglect it. This study aimed to close this gap by for the first time quantifying and...

Data from: Seasonal and spatial dynamics of gas ebullition in a temperate water-storage reservoir

Michal Tušer, Tomáš Picek, Zuzana Sajdlová, Tomáš Jůza, Milan Muška & Jaroslava Frouzova
Gas ebullition of river impoundments plays an increasingly significant role, particularly in transporting methane CH4 from their sediments to the atmosphere, and contributing to the global carbon budget and global warming. Quantifying stochastic and episodic nature of gas ebullition is complicated especially when conventionally conducted by using coverage-limited gas traps. Current knowledge of seasonality in a reservoir’s gas ebullition is lacking in the literature. For this reason, advanced acoustic surveying was intensively applied to determine...

Data from: Highly divergent 16S rRNA sequences in ribosomal operons of Scytonema hyalinum (Cyanobacteria)

Jeffrey R. Johansen, Jan Mareš, Nicole Pietrasiak, Markéta Bohunická, , Lenka Štenclová & Tomáš Hauer
A highly divergent 16S rRNA gene was found in one of the five ribosomal operons present in a species complex currently circumscribed as Scytonema hyalinum (Nostocales, Cyanobacteria) using clone libraries. If 16S rRNA sequence macroheterogeneity among ribosomal operons due to insertions, deletions or truncation is excluded, the sequence heterogeneity observed in S. hyalinum was the highest observed in any prokaryotic species thus far (7.3–9.0%). The secondary structure of the 16S rRNA molecules encoded by the...
