New insights into the karyotype evolution of the free-living flatworm Macrostomum lignano (Platyhelminthes, Turbellaria) [PDF]

Scientific Reports, 2017
The free-living flatworm Macrostomum lignano is a model organism for evolutionary and developmental biology studies. Recently, an unusual karyotypic diversity was revealed in this species.

Seasonal Dynamics of Benthic Macroinvertebrate Community Assembly in a Subtropical Monsoon-Driven Mountain Stream. [PDF]

Ecol Evol
This study examines how seasonal hydrological variations influence macroinvertebrate community assembly in the Huishui River using the EMS framework and variation partitioning analysis. The findings reveal that dispersal processes dominate during high‐flow monsoon periods, environmental filtering prevails in drought phases, and both processes ...

Responses of Freshwater Planarian Girardia tigrina to Fipronil-Based Insecticide: Survival, Behavioral and Physiological Endpoints

Diversity, 2022
Fipronil is a pyrazole insecticide used to control undesirable insect populations. Due to its large-scale application, there is the potential for surface waters’ contamination, with toxic action for non-target organisms, and consequent impacts on aquatic

Species composition and abundance of free-living turbellarians in three different wetlands in Southern Brazil

Anais da Academia Brasileira de Ciências, 2022
Free-living turbellarians mostly live in marine and freshwater environments, but they have been little considered in ecological studies. The coastal plain in southern Brazil harbors a diverse fauna and flora, but only a few studies have related ...

Recovery and Degradation Drive Changes in the Dispersal Capacity of Stream Macroinvertebrate Communities. [PDF]

Glob Chang Biol
Freshwater ecosystems across Europe are recovering unevenly despite restoration efforts, partly due to the limited ability of many species to disperse. Using a dataset of over 1300 time series, we found that improved ecological quality often leads to gains in macroinvertebrate species with strong dispersal capacities, while degrading sites lose these ...

The Influence of Native Deer on Forest Fauna-A Systematic Map. [PDF]

Ecol Evol
Deer are key drivers of faunal communities in temperate and boreal forest ecosystems. In this systematic map, we review the current literature assessing the effects of native deer on abundance, species richness, and diversity of forest‐dwelling faunal taxa.

TURBELLARIA FROM SOMALIA [PDF]

Monitore Zoologico Italiano. Supplemento, 1987
SUMMARY The genus Pseudomonocelis Meixner, 1943 is treated in a monographic way, with the provisory re-introduction of P. agilis (Schulze, 1851). A comprehensive description of all representatives of the genus is given, including two new species from the neighbourhood of Mogadiscio, Somalia, P. pardii and P. cavernicola.

The Core of the Matter-Importance of Identification Method and Biological Replication for Benthic Marine Monitoring. [PDF]

Ecol Evol
Benthic macrofauna are important and widely used biological indicators of marine ecosystems as they have limited mobility and therefore integrate the effects of local environmental stressors over time. We here compare environmental DNA metabarcoding obtained from sediments with conventional morphological identification of benthic macrofauna.
