Dynamic social interactions and keystone species shape the diversity and stability of mixed-species biofilms – an example from dairy isolates - Dataset
<p>We previously reported a bacterial four-species biofilm model comprising <i>Stenotrophomonas rhizophila </i>(SR), <i>Bacillus licheniformis </i>(BL), <i>Microbacterium lacticum </i>(ML), and <i>Calidifontibacter indicus</i> (CI) that were isolated from the surface of a dairy pasteuriser after cleaning and disinfection. These bacteria produced 3.13-fold more biofilm mass compared to the sum of biofilm masses in monoculture (<a href="https://doi.org/10.3389/fmicb.2023.1159434">https://doi.org/10.3389/fmicb.2023.1159434</a>). In a subsequent experiment we confirmed that the observed community synergy resulted from dynamic social interactions among various species pairs, encompassing commensalism, exploitation, and amensalism. <i>M. lacticum</i> appeared to be the keystone species as it increased the growth of all other species that led to the synergy in biofilm mass. Interactions among the other three species (in the absence of <i>M. lacticum</i>) also contributed towards the synergy in biofilm mass. Bacterial cell-free-supernatants were also investigated to assess the nature of the observed synergy. The first four sheets of the Excel file contain raw cell count data for the four species (SR, BL, ML, and CI), recorded every 4 h over a 24 h period on the surface of stainless steel (SS) in the presence of brain-heart-infusion (BHI) medium and skim-milk (SM). Data related to individual bacterial cell counts in various mixed-species biofilms are also presented. These biofilms were developed on SS in BHI for h. Data related to bacterial biofilm masses in different mixed-species biofilm combinations are also presented, showcasing the effect of replacing one strain with its CFS. Species written in red indicate that their CFS was used, not their viable form. </p>
Dispersal limitation predicts the spatial and temporal filtering of tropical bird communities in isolated forest fragments
<p>The link between dispersal traits and patterns of community assembly remains a frontier in understanding how vertebrate communities persist in fragmented landscapes. Using experimental release trials and intensive field surveys of bird communities in fragmented forests of the Peruvian and Colombian Andes, we demonstrate that morphological traits related to movement (1) predict experimental flight performance and (2) exhibit dispersal-mediated environmental filtering at the community scale. After correcting for body size, four traits hypothesized to influence flight ability (wing length, wing pointedness, wing loading, and eye size) predicted distance flown across a hostile experimental landscape, with successful species having significantly longer pointed wings, carrying less mass per unit wing area (i.e., lower wing loading), and having smaller eyes. Species with larger eyes also displayed increased flight latency, potentially due to disability glare. At the community scale we detected a gradient of dispersal-mediated environmental filtering in fragments compared to reference forest within the same landscape, with relative differences in trait values explained by the temporal and spatial extent of patch isolation. In the Colombian landscape where fragments had been isolated for > 60 years, communities were filtered for species with long and narrow wings and small eyes, especially within the most spatially isolated fragments. We observed the opposite pattern in the more recently fragmented Peruvian landscape (15-30 years): communities within fragments tended to have shorter and more rounded wings compared to those in nearby contiguous forests, suggesting that dispersal-limited species accumulate in the initial years following patch isolation due to "restricted dispersal" and represent an extinction debt yet to be paid. Our results (1) experimentally validate the use of morphological traits as proxies for movement ability in fragmented landscapes, (2) demonstrate that visual acuity functions as a novel dimension of dispersal limitation, and (3) quantify how the spatial and temporal components of patch isolation produce a gradient in dispersal-mediated environmental filtering and extinction debt for communities inhabiting fragments.</p>
