Seascape Context as a Driver of the Fish Community Structure of Posidonia oceanica Meadows in the Adriatic Sea

open access: yesCroatian Journal of Fisheries, 2021
Marine underwater habitats dominated by seagrass Posidonia oceanica play an essential role in fish community assembly, affecting taxonomic and functional diversity, abundance and fish behavior.

Determining the relative importance of catchment- and site-scale factors in structuring fish assemblages in small coastal streams

open access: yesKnowledge and Management of Aquatic Ecosystems, 2017
Coastal streams provide important habitat for many diadromous fish species, which migrate between freshwater and the sea during their life cycle. However, coastal systems are poorly studied in comparison to large, continental river systems.

The structure of eusocial bee assemblages in Brazil [PDF]

open access: yesApidologie, 2006
Les relations abeilles sociales-plantes alimentaires ont ete abondamment etudiees, en particulier dans les neotropiques. Il s'agit pourtant de la premiere comparaison quantitative et d'une synthese d'un large ensemble d'etudes (28) remarquablement similaires s'interessant aux plantes alimentaires des abeilles eusociales au Bresil (Tab. I, Fig. 1).

Change and recovery of coastal mesozooplankton community structure during the Deepwater Horizon oil spill

open access: yesEnvironmental Research Letters, 2014
The response of mesozooplankton community structure to the Deepwater Horizon oil spill in the northern Gulf of Mexico was investigated using data from a long-term plankton survey off the coast of Alabama (USA).

Drivers of phylogenetic structure in Amazonian freshwater fish assemblages [PDF]

open access: yesJournal of Biogeography, 2021
ABSTRACT Aim Community phylogenetics provides important information about the evolutionary and ecological factors help structure regional species assemblages. Here, we analyze phylogenetic diversity (phylodiversity) patterns among fish species in 97 sub-drainages of the Amazon basin, to evaluate the ...

Population structure of graptolite assemblages [PDF]

open access: yesLethaia, 1998
Graptolite rhabdosomes display a diverse suite of morphologies. The range of morphotypes present within most moderate to high diversity assemblages from the Ordovician and Silurian is similar, despite the different taxonomic composition of the faunas at different times.

Comparing lacustrine environments: the importance of the kind of habitat on the structure of fishes

open access: yesActa Limnologica Brasiliensia, 2018
Aim Fish diversity in two lentic environments: a lake connected (Barbosa lake) to a river and an artificial reservoir (Ninfeias reservoir) were determined in the dry and rainy periods in 2015. We expected to find more diversity in the connected lake and

Ground beetle assemblages (Coleoptera, Carabidae) of the Krasiborska Kępa reserve

open access: yesActa Biologica, 2016
The study was carried out from the beginning of June to the end of July 2005 in the Krasiborska Kępa reserve (UTM VV56; 53.848°N, 14.370°E). Three research plots were established, representing various types of use of reedy areas: an unused reedy ...

Temporal and spatial changes in macrozoobenthos diversity in Poyang Lake Basin, China

open access: yesEcology and Evolution, 2019
Poyang Lake plays a significant role in maintaining and replenishing the macrozoobenthos biodiversity in the middle Yangtze River. However, due to human activities and natural factors, the habitat of Poyang Lake has been seriously degraded, resulting in ...

Co-occurrence between macrophytes and macroinvertebrates: towards a new approach for the running waters quality evaluation?

open access: yesJournal of Limnology, 2014
Several studies on concordance between macrophyte and macroinvertebrate communities were carried out for decades while any investigation on co-occurrence of single pair of taxa of these two groups was never addressed.
