An Invisible Threat to Natural Heritage: Examples of Large Protected Areas with Hg-Enriched Freshwater Environments

open access: yesHeritage
Freshwater environments of large protected areas such as national parks and biosphere reserves concentrate a significant amount of natural heritage. An active release of mercury (Hg) to the global environment may challenge the state of this heritage. The

Phylogeography of higher Diptera in glacial and postglacial grasslands in western North America

open access: yesBMC Ecology, 2019
Background Pleistocene glaciations have had an important impact on the species distribution and community composition of the North American biota. Species survived these glacial cycles south of the ice sheets and/or in other refugia, such as Beringia. In

Does Long-Term Macrophyte Management in Lakes Affect Biotic Richness and Diversity? [PDF]

open access: yes, 2005
We hypothesize that the richness and diversity of the biota in Lake Moraine (42°50’47”N, 75°31’39”W) in New York have been negatively impacted by 60 years of macrophyte and algae management to control Eurasian watermilfoil ( Myriophyllum spicatum L.

Influence of transport and ocean ice extent on biogenic aerosol sulfur in the Arctic atmosphere [PDF]

open access: yes, 2012
The recent decline in sea ice cover in the Arctic Ocean could affect the regional radiative forcing via changes in sea ice-atmosphere exchange of dimethyl sulfide (DMS) and biogenic aerosols formed from its atmospheric oxidation, such as methanesulfonic ...

Global diversification of coastal Cafius rove beetles (Coleoptera: Staphylinidae) driven by ocean currents since the early Miocene

open access: yesCladistics, Volume 42, Issue 1, Page 79-94, February 2026.
Abstract As our understanding of abiotic factors continues to grow, along with insights into the biological traits of organisms, so too does the sophistication of studies exploring global diversification and spatio‐temporal distribution patterns. The global distribution of coastal Cafius rove beetles, combined with the endemic distribution patterns ...

A summary of the endemic beetle genera of the West Indies (Insecta: Coleoptera); bioindicators of the evolutionary richness of this Neotropical archipelago [PDF]

open access: yes, 2012
The Caribbean Islands (or the West Indies) are recognized as one of the leading global biodiversity hot spots. This is based on data on species, genus, and family diversity for vascular plants and non-marine vertebrates.
