Other taxa identified with low dispersal capacity will be more sensitive to longitudinal connectivity in the watershed. Therefore, we echo the recent call on the importance of considering both cross-ecosystem (lateral) and longitudinal connectivity as targets for conservation planning.

bottom-line 1: Despite nuances and a call for further investigations, those results suggest that shredders and predators could be key transmission belts in the propagation of cross-ecosystem perturbations because of their strong associations with variations in terrestrial subsidy quality.

b) dispersal traits: Taxa with high dispersal capacity were more abundant in lakes with lower connectivity compared to taxa with low dispersal capacity. BUT no associations with resource quality! Thus no site selection based on resource quality, whether directly or by proxy.

a) feeding traits: we were surprised that predators (R2=0.5) association with quality (t-POM phosphorus) was much stronger than shredders (R2=0.01). But then, predators are prone to stoichiometric imbalance, and shredders might be limited by other metrics of quality (fungal biomass, toughness etc.).

Identifying key traits associated with cross-ecosystem resource inputs is an essential step toward developing a general understanding of how perturbations can propagate across ecosystems. We thought a) feeding traits and b) capacity to move and track resource quality were good starting points.

3. Main local drivers of prevalence mainly involved abiotic factors but most interestingly to me we found strong evidence for a biotic dilution effect (community with more none-host species tend to have some protecting effects on host species). To know more - look at the paper - :-)

....to the fact that they interact with fish "personality" and movement range and thus they overall simply sample different parts of the community (and location in the waterbody). Interestingly though, in terms of prevalence estimation, they tend to converge with sampling effort to similar values!👇

Main findings are: 1. Because of spatial aggregation in infection prevalence, small sampling effort led to an important overestimation of prevalence. Fortunately the threshold to reach a good estimate is not very high. 2. Fishing methods do influence results owing probably...👇

Important : an english version of the ad will be posted very soon !

Would love to join if possible thanks

Merci Nicolas - must admit I have no clue how those starter package works - but happy to be on the list :-) - thanks!

Merci Julie !...this was a true "slow-science" project that started in 2017 following a discussion with Shawn Leroux, and it would have never seen the day without stellar works from Anne McLeod...was well worth the wait ! ;-)
