Cryptic species in tropic sands--interactive 3D anatomy, molecular phylogeny and evolution of meiofaunal Pseudunelidae (Gastropoda, Acochlidia) [PDF]

open access: yes, 2011
Towards realistic estimations of the diversity of marine animals, tiny meiofaunal species usually are underrepresented. Since the biological species concept is hardly applicable on exotic and elusive animals, it is even more important to apply a ...

Karst spring microbial diversity differs across an oxygen-sulphide ecocline and reveals potential for novel taxa discovery

open access: yesActa Carsologica, 2019
Strong geochemical gradients of dissolved oxygen and sulphide establish habitats where specialized bacterial and archaeal taxonomic groups occupy specific redox-sensitive niches, primarily based on metabolic and ecological requirements.

Evaluation of Yellow Mealworm (Tenebrio molitor) Larvae Meal as a Carbon Source in Biofloc System for Dwarf Crayfish (Cambarellus montezumae) Culture [PDF]

open access: yesAquaculture nutrition.
The aim of this study was to evaluate the use of Tenebrio molitor larvae meal as a carbon source in a biofloc system (BFT) to optimize the culture of C. montezumae. A trial was conducted for 24 weeks, 500 T. molitor larvae were reared with wheat bran as substrate, and hydration once a week; at the end, 9000 T.

Evaluation of sampling methods for periphytic fauna in macrophytes at the Espinhaço Mountain Range Biosphere Reserve, Minas Gerais State, Brazil = Avaliação dos métodos de amostragem para fauna perifítica em macrófitas na Reserva da Biosfera, Serra do Espinhaço, Estado de Minas Gerais, Brasil

open access: yesActa Scientiarum: Biological Sciences, 2008
The methods “Jar”, “Manual Removal” and “modified Ekman Dredge” wereevaluated for sampling periphyton fauna associated with aquatic macrophytes. Sixty-three samples were collected from five lentic and three lotic water bodies at the Espinhaço Mountain ...

Gastrotricha – not only in sediments: new epiphytic species of Chaetonotida from the Jubilee Greenhouse of the Botanical Garden in Kraków

open access: yesEuropean Journal of Taxonomy, 2019
Although Gastrotricha have previously been recorded in bottom sediments of greenhouses as well as in micro-reservoirs of Bromeliaceae, palm houses provide a more specific microhabitat for these animals that often originate from different regions of the ...

The Structuring Role of Rhodolith Beds on Meiobenthic Communities in the Mediterranean Sea

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 2, February 2025.
ABSTRACT Rhodolith beds are globally distributed structurally complex habitats formed by the aggregation of unattached forms of non‐geniculate coralline red algae. They provide key ecosystem functions and services, supporting feeding, settlement and nursery provision for several species.

Bending the curve of global freshwater biodiversity loss: what are the prospects?

open access: yesBiological Reviews, Volume 100, Issue 1, Page 205-226, February 2025.
ABSTRACT Freshwater biodiversity conservation has received substantial attention in the scientific literature and is finally being recognized in policy frameworks such as the Global Biodiversity Framework and its associated targets for 2030. This is important progress.
