“…These studies focused on a large variety of taxonomic groups (from bacteria and fungi to mammals and trees) and differed greatly in their sampling grain (from guts of individual chironomid larvae [Lemes‐Silva et al. ] to blocks of roughly 25 km 2 [von Gagern et al. ]).…”

“…We obtained data on analysis grain from 60 studies published between 2004 and 2017 (Appendix S1: Table S1). These studies focused on a large variety of taxonomic groups (from bacteria and fungi to mammals and trees) and differed greatly in their sampling grain (from guts of individual chironomid larvae [Lemes-Silva et al 2014] to blocks of roughly 25 km 2 [von Gagern et al 2015]). We did not find a single study besides McNickle et al (2017) that quantified co-occurrence patterns across multiple sampling grains within a single spatial hierarchical level (e.g., a landscape), though a few studies analyzed co-occurrence patterns at more than one hierarchical level.…”

Tree species co‐occurrence patterns change across grains: insights from a subtropical forest

et al. 2018

Co‐occurrence is a basic measure of spatial relationships between species. This commonly used measure has many benefits and limitations, yet a basic property that can strongly affect it has been overlooked. Co‐occurrence analysis is based on discrete sampling in space, and therefore, its grain size may affect the results and their interpretation, because species interactions and their environmental responses are scale‐dependent. We utilized a large dataset on tree species from a full‐stem mapped forest plot in China as a template for testing the effects of grain on species co‐occurrence patterns. We quantified co‐occurrence patterns for large trees and saplings in nested sampling plots with increasing radii and analyzed the effect of plot size on co‐occurrence. Co‐occurrence patterns varied greatly across grains. More than half of the species in large trees we analyzed had significantly non‐random co‐occurrence patterns at some grain. In contrast, saplings exhibited much fewer non‐random co‐occurrences. The proportion of segregated species pairs of large trees had a unimodal relationship with grain, whereas the proportion of aggregated species was positively related to grain. These patterns disappeared in saplings, suggesting that spatial interactions among trees are more prominent among larger individuals. Therefore, co‐occurrence patterns are scale‐dependent, and this scale dependency reflects a mixture of ecological (interspecific interactions, environmental responses) and statistical (sampling effects) processes. Our results suggest that insights from single‐grained studies cannot be generalized.

“…These include Dytiscidae, Simuliidae, Notonectidae, Hirudinea and Planariidae. Further, Chironomidae larvae were not considered in the analysis of functional feeding groups because of their wide range of feeding habits (Lemes‐Silva, Pagliosa, & Petrucio, ). Each taxon was assigned to a functional feeding group based on Merritt and Cummins ().…”

Macroinvertebrate‐based bioassessment of rivers in Addis Ababa, Ethiopia

Chemical-based studies have shown pollution of rivers in Addis Ababa, Ethiopia.However, as bioassessment is not a component of the river assessment and monitoring programmes, information on the ecological status of the rivers is limited. The study assessed the ecological status of the Little and Greater Akaki Rivers using macroinvertebrates. Macroinvertebrates were collected from twelve sites twice in the dry and wet seasons. There was abundance of few tolerant, collector-gatherer taxa with a loss of most sensitive taxa that used to be part of the river systems. Macroinvertebrate communities from upper and lower reaches showed complete differentiation on the nonmetric multidimensional scaling (NMS) ordination graph with upstream reaches composed of relatively sensitive taxa while the lower reaches dominated by tolerant taxa. Multiresponse permutation procedure (MRPP) showed significant difference between the two reaches. Macroinvertebrate communities from the dry and wet seasons did not show differentiation on the NMS ordination graph and MRPP did not show significant difference. Both rivers scored low in the South African Scoring System (SASS 5) and ETHbios, indicating ecological degradation. The results suggest that several decades of environmental degradation might have led to impoverished regional species pool, consisting mainly tolerant and generalist taxa constant throughout the year.

Larval chironomids feed on algae, diatomae, detritus, decaying plant and animal fragments. The larvae in turn are food for other carnivore and omnivore animals. Thus, larval chironomids have a very important role in the aquatic food cycle. In this study, the algal flora in the stomachs of Tanypus punctipennis, which is known as a very common species in Turkish Thrace, was examined in terms of qualitative and quantitative factors. It was found that Bacillariophyta was the dominant group with 42 taxa in the stomach of T. punctipennis. It was followed by Cyanophyta with 3 taxa, Euglenophyta with 6 taxa, Chlorophyta with 4 taxa, Carophyta with 2 taxa, and Rhodophyta with 1 taxa.
