Ecological network complexity scales with area
Galiana, Núria; Lurgi, Miguel; Bastazini, Vinicius A. G.; Bosch, Jordi; Cagnolo, Luciano; Cazelles, Kevin; Claramunt-López, Bernat; Emer, Carine [UNESP]Made available in DSpace on 2022-04-28T19:49:35Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Larger geographical areas contain more species—an observation raised to a law in ecology. Less explored is whether biodiversity changes are accompanied by a modification of interaction networks. We use data from 32 spatial interaction networks from different ecosystems to analyse how network structure c...
The geography of metapopulation synchrony in dendritic river networks
Larsen, Stefano; Comte, Lise; Filipe, Ana Filipa; Fortin, Marie-Josée; Jacquet, ClaireDendritic habitats, such as river ecosystems, promote the persistence of species by favouring spatial asynchronous dynamics among branches. Yet, our understanding of how network topology influences metapopulation synchrony in these ecosystems remains limited. Here, we introduce the concept of fluvial synchrogram to formulate and test expectations regarding the geography of metapopulation synchrony across waters...
Effects of nonnative species on the stability of riverine fish communities
Eros, Tibor; Filipe, Ana Filipa; Ruhi, Albert; Pablo, A.; Tedesco, P.A.; Brose, Ulrich; Fortin, Marie-JoséeDespite the increasing ubiquity of biological invasions worldwide, little is known about the scale-dependent effects of nonnative species on real-world ecological dynamics. Here, using an extensive time series dataset of riverine fish communities across different biogeographic regions of the world, we assessed the effects of nonnative species on the temporal variability and synchrony in abundance at different o...
