Do wider riparian zones alter benthic macroinvertebrate assemblages’ diversity and taxonomic composition in neotropical headwater streams?

open access: yesActa Limnologica Brasiliensia, 2021
: Aim The maintenance and condition of riparian vegetation are important factors for conserving headwater streams and their species diversity. Thus, variations in the width of a riparian zone can have dramatic effects in the structure and functioning of

Habitat expansion of a tropical chironomid by seasonal alternation in use of littoral and profundal zones

open access: yesJournal of Limnology, 2022
The consistent warming of tropical lakes at all depths causes rapid development and long persistence of seasonal hypoxia in the hypolimnion, which greatly reduces the biodiversity of hypolimnetic benthic invertebrates. Full mixing of the water column in

Response of Benthic Fauna to Habitat Heterogeneity in a Shallow Temperate Lake

open access: yesAnimals, 2021
We investigated the response of benthic macroinvertebrates in the eulittoral, infralittoral, and sublittoral zones, in two segments of the freshwater Lake Wicko on the coast of the Baltic Sea.

Biostratigraphy and paleoenvironment of Maastrichtian foraminiferal assemblages from a succession located NW of Tuxtla Gutiérrez, Chiapas (SE Mexico)

open access: yesRevista Mexicana de Ciencias Geológicas, 2021
During the Maastrichtian, two lithostratigraphic units were deposited in the central Chiapas region; the Ocozocoautla and Angostura formations. The first unit crops out northwest of the city of Tuxtla Gutiérrez in central Chiapas.

Marine invertebrate and seaweed biodiversity of continental coastal Ecuador [PDF]

open access: yesBiodiversity Data Journal, 2020
This study summarises the diversity of living macroinvertebrates and seaweeds from the intertidal and subtidal rocky shores along Ecuadorian continental coast. Benthic macroinvertebrate communities and seaweeds were quantified over quadrants (50 × 50 cm)

Spatial heterogeneity of coral reef benthic communities in Kenya.

open access: yesPLoS ONE, 2020
Spatial patterns of coral reef benthic communities vary across a range of broad-scale biogeographical levels to fine-scale local habitat conditions. This study described spatial patterns of coral reef benthic communities spanning across the 536-km coast ...
