Dynamic of epigeous macrofauna under organic soil management in the Brazilian semi-arid region
Dinâmica da macrofauna epígea sob manejo orgânico do solo no semi-árido brasileiro

open access: yesSemina: Ciências Agrárias, 2012
Soil macrofauna is responsible for soil fertility through cycling of nutrients, tillage and fragmentation of organic matter, as well as through the association between groups of fauna with conserved and/or degraded pedoenvironments.

Investigating soil mesofauna cryptic diversity: Current challenges and perspectives

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 8, Page 1587-1598, August 2025.
Abstract Cryptic species lacking distinct morphological features are widespread among soil fauna, including such functionally significant groups as springtails, mites and enchytraeids. Their presence, diversity and biomass may impact ecosystem services provided by belowground ecosystems.

Trophic ecology of the freshwater prawn, Pseudopalaemon bouvieri (Decapoda: Palaemonidae) in Northeastern Argentina: with remarks on population structure

open access: yesRevista de Biología Tropical, 2012
Freshwater decapod crustaceans are important components of food webs in these environments, but little is known about the diet of species that live in tropical waters. We studied the feeding ecology of the prawn Pseudopalaemon bouvieri and its population

The Role of Earthworms in Mediating Environmental Impacts on Mountain Ecosystem Functioning

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 8, August 2025.
ABSTRACT Aim Soils host a quarter of all terrestrial species, and the pivotal role played by earthworms in soil ecosystem functioning is thought to be paramount. Here, we aimed to quantify the causal influence of changing environments, especially climate, soil conditions, and vegetation type and structure, on earthworm diversity and the subsequent ...

Acute toxicity of birch tar oil on aquatic organisms

open access: yesAgricultural and Food Science, 2008
Birch tar oil (BTO) is a by-product of processing birch wood in a pyrolysis system. Accumulating evidence suggests the suitability of BTO as a biocide or repellent in terrestrial environments for the control of weeds, insects, molluscs and rodents.

Technical challenges in the implementation of macroinvertebrate DNA metabarcoding in river biomonitoring: A case study from peninsular Spain—Advantages, limitations and roadmap

open access: yesEcological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
This study evaluates the opportunities and challenges of using DNA metabarcoding of river macroinvertebrates for routine ecological status assessment under the EU Water Framework Directive. By reanalysing data from rivers in north‐west Spain, it identifies key sources of false positives and negatives, compares bulk and eDNA sampling with traditional ...

Ecological studies on some lakes of the Amazon valley

open access: yes, 1967
Of the three types of lakes studied, clear water, white water, and brown water, the white water lakes are the only ones to have a reasonable autochtonous production of organic matter. Owing probably to the lack of mineral salts, the primary production is
