Data from: Linking radial growth patterns and moderate-severity disturbance dynamics in boreal old-growth forests driven by recurrent insect outbreaks: a tale of opportunities, successes, and failures

Maxence Martin, Cornélia Krause & Hubert Morin
In boreal landscapes, emphasis is currently placed on close-to-nature management strategies, which aim to maintain the biodiversity and ecosystem services related to old-growth forests. The success of these strategies, however, depends on an accurate understanding of the dynamics within these forests. This study aims to reconstruct the disturbance and post-disturbance dynamics in boreal old-growth forests that are driven by recurrent moderate-severity disturbances. We studied eight old-growth forests in Québec, Canada, that has recorded recurrent and...

The BenBioDen database, a global database for meio-, macro- and megabenthic biomass and densities

Tanja Stratmann, Dick Van Oevelen, Pedro Martínez Arbizu, Chih-Lin Wei, Jian-Xiang Liao, Mathieu Cusson, Ricardo A. Scrosati, Philippe Archambault, Paul V. R. Snelgrove, Patricia A. Ramey-Balci, Brenda J. Burd, Ellen Kenchington, Kent Gilkinson, Rénald Belley & Karline Soetaert
Benthic fauna refers to all fauna that live in or on the seafloor, which researchers typically divide into size classes meiobenthos (32/ 64 µm – 0.5/ 1 mm), macrobenthos (250 µm – 1 cm), and megabenthos (> 1 cm). Benthic fauna play important roles in bioturbation activity, mineralization of organic matter, and in marine food webs. Evaluating their role in these ecosystem functions requires knowledge of their global distribution and biomass. We therefore established the...

Deciphering lifelong thermal niche using otolith δ18O thermometry within supplemented lake trout (Salvelinus namaycush) populations

Olivier Morissette, Louis Bernatchez, Michael Wiendenbeck & Pascal Sirois
1. The selection of thermal habitat by fish is strongly regulated by physiology and behaviour. However, delineation of a species lifelong thermal niche remains technically challenging. Lake trout (Salvelinus namaycush) survival and productivity are recognised as being tightly linked to a somewhat restricted thermal habitat. The factors guiding temperature selection during each life stage remain poorly understood. 2. In this study, we tested the significant factors controlling the realised thermal niche of lake trout from...

Temperature drives caste-specific morphological clines in ants

Jean-Philippe Lessard, François Brassard, André Francoeur & Jean-Philippe Lessard
The morphology of organisms relates to most aspects of their life history and autecology. In particular, morphology can reflect adaptation to the abiotic environment in which species occur. As such, elucidating the drivers of morphological variation along environmental gradients might give insight into processes limiting species distributions. In eusocial organisms, the concept of morphology is more complex than in solitary organisms. Eusocial insects such as ants exhibit drastic morphological differences between reproductive and worker castes....
