“…Mesocosm experiments performed at constant hydrodynamic stress showed that the effect of individual bioturbation activity on sediment resuspension can be scaled to the population level (Cozzoli, et al, 2018a). This concept is also supported by the recent work of Wrede et al (Wrede, et al, 2018), demonstrating that size scaling rules of metabolic rates can provide a base to predict the intensity of bioirrigation at community level.…”

“…Beyond coastal morphology, sediment resuspension is related to the oxygenation and the transfer of particles and nutrients within the sediment layers and from the sediment surface to the water column (Ubertini, et al, 2012). For this reason, bioturbation may have a broad influence on biogeochemical cycles Quintana, et al, 2015;Thomsen, et al, 2017;Zhang, et al, 2017;Wrede, et al, 2018), pollutants diffusion (Kupryianchyk, et al, 2013) species coexistence (Mermillod-Blondin & Lemoine, 2010;…”

“…Species-specific trait-based models proved to have good performance in the quantitative prediction of the intensity of sediment reworking Queirós, et al, 2013;Queirós, et al, 2015) and of closely related processes as bioirrigation (Wrede, et al, 2018). However, formulating a general mechanistic framework to quantify bioturbation processes based on species-specific functional traits remains difficult due to the high variation in bioturbators' species distribution and functional behaviour, that is hardly predictable in detail (Queirós, et al, 2013).…”

Macrozoobenthos may affect sediment stability and erodibility via their bioturbating activities, thereby impacting both the short-and long-term development of coastal morphology. Process-based models accounting for the effect of bioturbation are needed for the modelling of erosion dynamics. With this work, we explore whether the fundamental allometric principles of metabolic activity scaling with individual and population size may provide a framework to derive general patterns of bioturbation effect on cohesive sediment resuspension. Experimental flumes were used to test this scaling approach across different species of marine, soft-sediment bioturbators. The collected dataset encompasses a range of bioturbators functional diversity, individual densities, body sizes and overall population metabolic rates. Measurements were collected on a range of hydrodynamic stress from 0.02 to 0.25 Pa. Overall, we observed that bioturbators are able to slightly reduce the sediment resuspension at low hydrodynamic stress, whereas they noticeably enhance it at higher levels of stress. Along the whole hydrodynamic stress gradient, the quantitative effect of bioturbators on sediment resuspension can be efficiently described by the overall metabolic rate of the bioturbating benthic communities, with significant variations across the bioturbators' taxonomic and functional diversity. One of the tested species (the gallery-builder Polychaeta Hediste diversicolor) had an effect that was partially deviating from the general trend, being able to markedly reduce sediment resuspension at low hydrodynamic stress compared to other species. By combining this trend with hydrodynamic forces, we were able to produce a process-based model of biota-mediated sediment resuspension.

“…This implies that the simplified BPs demands at least the taxonomic experience to assess whether a given fauna assemblage is sufficiently diverse, and whether the general lifestyle mode does not indicate against BP s application, for example a purely sessile community from a hard substrate. Our conclusions should be verified with additional datasets. The analyses should also include the similar community bioirrigation potential (IP c ), which was derived from the BPc (Wrede et al 2018), and is different in details. A potential consequence could be that diverse benthos communities could have a similar ratio of bioirrigation potential and bioturbation potential although this is not necessarily true for the actual rates of bioirrigation and bioturbation.…”

The mobility of particles and solutes within aquatic sediment is substantially impacted by faunal bioturbation activities such as bioirrigation and sediment reworking. The non-quantitative community bioturbation potential (BPc) aims to estimate the potential of a given benthic community for bioturbation activities, based on the functional traits of the species within that community. We argue that in sufficiently diverse communities, the characteristics of individual species, expressed as traits scores, average each other out, and approach a universal constant. This enables to derive a simpler community bioturbation potential (BPs), which may be applied in cases when taxonomic expertise or trait data are not available. As a proof of concept, we evaluated a dataset of 84 benthos assemblages, and found a high degree of agreement of full BPc and simplified BPs.

The unprecedented loss of biological diversity has negative impacts on ecosystems and the associated benefits which they provide to humans. Bromeliads have high diversity throughout the Neotropics, but they have been negatively affected by habitat loss and fragmentation, climate change, invasive species, and commercialization for ornamental purpose. These plants provide direct benefits to the human society, and they also form microecosystems in which accumulated water and nutrients support the communities of aquatic and terrestrial species, thus maintaining local diversity. We performed a systematic review of the contribution of bromeliads to ecosystem services across their native geographical distribution. We showed that bromeliads provide a range of ecosystem services such as maintenance of biodiversity, community structure, nutrient cycling, and the provisioning of food and water. Moreover, bromeliads can regulate the spread of diseases, and water and carbon cycling, and they have the potential to become important sources of chemical and pharmaceutical products. The majority of this research was performed in Brazil, but future research from other Neotropical countries with a high diversity of bromeliads would fill the current knowledge gaps and increase the generality of these findings. This systematic review identified that future research should focus on provisioning, regulating, and cultural services that have been currently overlooked. This would enhance our understanding of how bromeliad diversity contributes to human welfare, and the negative consequences that loss of bromeliad plants can have on communities of other species and the healthy functioning of the entire ecosystems.
