Mexican Journal of Medical Research ICSA, 2013 The health of an ecosystem can be examined through the use of bioindicators (BI), while the health of a human being can be determined using some molecules such as biomarkers (BM). BI are complete organisms or part of them that can be measured to detect changes in the environment, the presence of pollution and its effect on the ecosystem, as well as the

Boreas, EarlyView.Understanding the temperature variability of past interglacial cycles is essential to predict future climates. We present a new summer temperature reconstruction, based on the subfossil chironomid record from a small palaeolake adjacent to the Middle Palaeolithic site of Lichtenberg, northern Germany. The record spans from the Saalian late glacial over

Boreas, EarlyView.Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Fly me to the canopy: Diptera communities in oak forest crowns as bioindicators of stand decline
Insect Conservation and Diversity, EarlyView.Diptera diversity: Oak decline increases the overall Diptera diversity, particularly in saproxylic and floricolous guilds, likely due to more open canopies and greater deadwood and floral resource availability. Family responses: Dolichopodidae, Empididae, Hybotidae and Anthomyiidae thrive in declining stands, whereas Mycetophilidae and other fungus ...

Journal of Fish Biology, EarlyView.Abstract Hydropeaking is considered an important stressor for salmonids and other species in rivers affected by hydropower. In this study, we investigated the in situ effects of hydropeaking on the survival of eggs and larvae of fall spawning brown trout as well as spring spawning Danube salmon.

Freshwater Biodiversity Research in Brazil: Trends from a Systematic Review and Topic Modeling
International Review of Hydrobiology, Volume 111, Issue 2, December 2026.ABSTRACT Brazil is a megadiverse country that hosts six major biomes and a vast freshwater network. Despite this richness, research on freshwater biodiversity has been heterogeneous across regions, communities, and time, leaving significant knowledge gaps.

Dwarf shrubs as bioindicators. [PDF]
Silva Fennica, 1981 Several studies of air polluted forest environments have shown that dwarf shrubs suffer from air pollution. In many cases the disturbances have been attributed to the susceptibility of the dwarf shrubs, while in some cases the vegetational competition factor has been discussed.

Diversity and Distributions, Volume 32, Issue 7, July 2026.ABSTRACT Aim Our research aimed to assess the beta diversity of Chironomidae (Diptera) and faunal connections across springs, streams, and rivers within the Skadar Lake basin, a Mediterranean biodiversity hotspot, using DNA barcoding. Location Skadar Lake basin—a Mediterranean biodiversity hotspot. Methods We analysed mitochondrial cytochrome c oxidase
