“…The patterns of the LSDR across the two floodplain channels, considering the whole dataset including all the months, were both statistically significant, with similar slopes (i.e., −0.39 and −0.33 for MOLO and PONT, respectively) that were significantly shallower than predicted by Damuth [8][9][10]. Our patterns were consistent with several studies that suggested that the relationship between body size and abundance is much shallower than the value of −0.75 for aquatic macroinvertebrate communities (e.g., [26,[50][51][52]) and other animal communities (e.g., [19,[53][54][55][56]). However, the shallower slopes found were not consistent with the EER.…”

Body size is perhaps the most fundamental property of an organism and its relationship with abundance is one of the most studied relationships in ecology. Although numerous studies have examined these relationships in local communities, few have investigated how they vary at different temporal and spatial scales. We investigated the relationship between body size and abundance of local macroinvertebrate communities in two floodplain channels of the French upper Rhone River. The two channels differ in their vegetation coverage (high vs. low vegetation) and hydrological regimes. The shapes of the size–abundance relationship were similar between channels on a yearly basis but differed when compared between months. The variation in local size–abundance relationships between months was related to variation in the functional diversity across time. Our findings suggest that local size–abundance relationships are able to quantitatively describe temporal changes in community structure, showing the importance of relating diversity with ecosystem function in a more realistic context.

“…To date, several studies of CCSRs have been carried out on diverse assemblages of plants [26], phytoplankton [27], bacteria, algae and protozoa [20,28], fish, amphibians and macroinvertebrates [29][30][31][32], birds [33], and rodents [34]. However, the focus of these studies has been chiefly on the scaling exponent and whether it matches the theoretically predicted value of −3/4.…”

A Perspective on Body Size and Abundance Relationships across Ecological Communities

Recently, several studies have reported relationships between the abundance of organisms in an ecological community and their mean body size (called cross-community scaling relationships: CCSRs) that can be described by simple power functions. A primary focus of these studies has been on the scaling exponent (slope) and whether it approximates −3/4, as predicted by Damuth’s rule and the metabolic theory in ecology. However, some CCSR studies have reported scaling exponents significantly different from the theoretical value of −3/4. Why this variation occurs is still largely unknown. The purpose of our commentary is to show the value of examining both the slopes and elevations of CCSRs and how various ecological factors may affect them. As a heuristic exercise, we reanalyzed three published data sets based on phytoplankton, rodent, and macroinvertebrate assemblages that we subdivided according to three distinctly different ecological factors (i.e., climate zone, season, and trophic level). Our analyses reveal significant variation in either or both the CCSR slopes and elevations for marine phytoplankton communities across climate zones, a desert rodent community across seasons, and saltwater lagoon macroinvertebrate communities across trophic levels. We conclude that achieving a comprehensive understanding of abundance-size relationships at the community level will require consideration of both slopes and elevations of these relationships and their possible variation in different ecological contexts.

The Panhellenic Symposium of Oceanography andFisheries was firstly launched in Athens, 35 years agosparked by the enthusiasm of the Greek aquatic scientists,massively supported by the voluntary contributionof the Hellenic Centre for Marine Research (HCMR)employees. Over the last three decades, the Symposiumestablished and flourished as the forum for a wide rangeof marine and freshwater disciplines in the country. It becamea tradition to a large audience since it has attractedresearchers, academicians, students, entrepreneurs andthe industry both from Greece and adjacent countries.The initial enthusiasm and support is growing with theinclusion of Universities and other educational/researchinstitutes in the organization scheme.The “12th Panhellenic Symposium of Oceanographyand Fisheries” 1 did not only deliver big changes in itsoperational mode but also opened new horizons to thescientific communities of Greece and adjacent areas. Ithas been a tipping point in this type of events in manyaspects.
