Tropicalization of the Temperate Zone: Spatiotemporal Variability of Winter Warming and Declining Freeze Days Across the United States

International Journal of Climatology, EarlyView.
Unique characteristics of winter daily minimum (Tmin) and maximum (Tmax) temperatures and freeze days across the conterminous United States from 1952 to 2024 are examined. Results show spatial heterogeneity in Tmin/Tmax warming rates across the tropical‐temperate transition zone in the southeastern United States, and that the highest temperature on the

Insights into the Movements and Habitat Use of Blue Marlins (Makaira nigricans) in the Southwestern Atlantic Ocean

Fishes
Understanding the ecology of large pelagic fishes is important for species conservation and maintaining ecosystem dynamics. The Atlantic blue marlin (Makaira nigricans) is usually targeted in recreational fisheries and occasionally captured as bycatch in

Ecoregionalisation of the Southern Ocean Using Radiolarians

Frontiers in Marine Science, 2022
The Southern Ocean is an important region for identifying ecoregions, both to assist in conservation efforts as well as for paleoecological studies. In this paper we use the Southern Ocean Radiolarian Dataset (SORAD), a compilation of surface sediment ...

Chronic oil pollution harms Magellanic penguins in the Southwest Atlantic

Marine Pollution Bulletin, 2006
Petroleum pollution is a problem for seabirds along the Southwest Atlantic coast. Twenty-five groups from Salvador, Brazil (12 degrees 58'S) to San Antonio Oeste, Argentina (40 degrees 43'S) survey or rehabilitate sick or oiled seabirds. Four groups, one each in Brazil and Uruguay, and two in Argentina, kept counts of birds found alive and in need of ...

Analysis of Climate Variability of Homogeneous Regions of Rainfall Anomalies in Southeast South America (SESA)

International Journal of Climatology, EarlyView.
We studied rainfall variability and cyclicity in six Homogeneous Regions of Rainfall Anomalies (HRRA) in Southeast South America (SESA) from 1961 to 2020 to understand the occurrence of droughts and above‐average rainfall. We use a continental analysis scale, focusing on seasonal, interannual, and interdecadal cycles, and their association with modes ...

Spatiotemporal Changes and Climate Driving Factors of Compound Precipitation‐Temperature Extreme Events Across Global Land Areas

International Journal of Climatology, EarlyView.
During the period 1901–2024, the dominant proportion of compound dry‐warm extremes in annual, June–July–August (JJA), and December–January–February (DJF) occurrences was the highest among the four types of compound precipitation and temperature extremes across global land areas, accounting for 40.1%, 50.3%, and 28.0%, respectively.
