ORIGIN AND PREVALENCE OF HUMAN T-LYMPHOTROPIC VIRUS TYPE 1 (HTLV-1) AND TYPE 2 (HTLV-2) AMONG INDIGENOUS POPULATIONS IN THE AMERICAS

open access: yesRevista do Instituto de Medicina Tropical de São Paulo, 2015
Human T-lymphotropic virus type 1 (HTLV-1) is found in indigenous peoples of the Pacific Islands and the Americas, whereas type 2 (HTLV-2) is widely distributed among the indigenous peoples of the Americas, where it appears to be more prevalent than HTLV-

Bering Strait throughflow and the thermohaline circulation [PDF]

open access: yesGeophysical Research Letters, 2005
In this study, we employ a global coupled climate model to show that the Bering Strait is important to the variations of the thermohaline circulation. Three experiments are analyzed, a present day control run, and two freshwater hosing runs. Results show that as the thermohaline circulation weakens due to freshwater forcing in the northern North ...

The Contrasting Role of Fire in Shaping Landscape Genetic Patterns of Small Mammals Across Two Islands

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We evaluated how landscape features, including fire, influence genetic connectivity for three small mammal species in northern Australian savannas. Using resistance surface modelling across two islands with contrasting disturbance regimes, we found that fire, rainfall, and topography affected gene flow in species‐ and scale‐specific ways.

The Pacific‐Atlantic seesaw and the Bering Strait [PDF]

open access: yesGeophysical Research Letters, 2012
Paleo proxy data and previous modeling studies both indicate that the massive discharge of icebergs into the North Atlantic may have led to a (nearly) collapsed Atlantic meridional overturning circulation (AMOC), resulting in a seesaw‐like climate change between the North Pacific and North Atlantic, with a warming in the former and a cooling in the ...

Modelling the Sensitivity of Yukon River Biogeochemical Dynamics to Environmental and Chemical Drivers: Implications for Dissolved Organic Carbon

open access: yesHydrological Processes, Volume 40, Issue 4, April 2026.
We present a novel, process‐based, river model that effectively captures the interplay among hydrological, chemical, and soil parameters shaping riverine DOC transformations and reproduces observed DOC concentrations in the Yukon River. Sensitivity analysis highlights the importance of understanding the variability in DOC entering the headwater from ...

From barrier to gateway: Climate‐facilitated expansion of thaliaceans in the Arctic Ocean

open access: yesLimnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Thaliaceans (doliolids, pyrosomes, salps) play fundamental roles in global carbon cycling and pelagic food webs through high filtration rates and rapid reproduction. Despite their prevalence, they are virtually absent from the Arctic Ocean. This paper explores the ecological, physiological, and historical factors that may have contributed to ...

Phylogeny, species delimitation and machine learning bridge the gap between DNA sequences and morphology in the lichen genus Arctomia (Arctomiaceae, Ascomycota)

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract This study investigates species boundaries in the lichen genus Arctomia (Arctomiaceae, Ascomycota) using an integrative approach combining molecular phylogenetics, full Bayesian population delimitation, heuristic and model‐based species delimitation, and supervised machine learning applied to morphological data.

Comparison of environmental conditions in the Bering Sea and Davis Strait and the effects on microwave signature returns; March and April, 1979 [PDF]

open access: yes
Aircraft data collected in the Bering Sea in March, 1979 using a 6.6 GH sub z (C Band) microwave radiometer and a 13.9 GH sub z (Ku Band) scatterometer, reinforce the difficulties in interpreting first year ice types found near the ice edge in a marginal

Incidental Catch of Marine Mammals by Foreign and Joint Venture Trawl Vessels in the U.S. EEZ of the North Pacific, 1973-88 [PDF]

open access: yes, 1991
During 1973-88, 3,661 marine mammals of 17 species were reported as incidental catch by U.S. fishery observers aboard foreign and joint venture trawl vessels in the U.S. Exclusive Economic Zone in the North Pacific Ocean and the Bering Sea. Northern sea
