Heavy Metals in Soils: An Investigation of the Contaminated Floodplains Around the Sinu River, Colombia. [PDF]

Geohealth
Abstract Heavy metal contamination in rivers mostly originates from anthropogenic sources such as industrial activities, mining, agriculture, and urban runoff. These metals accumulate in river sediments and impact living organisms and the surrounding ecosystem. Historically, some rivers in Colombia have faced issues related to heavy metal contamination,

Harnessing the benefits of herbarium specimen digitisation for inferring recent and ongoing plant extinctions. [PDF]

New Phytol
Summary Evidence for the ongoing biodiversity crisis rests on assessment of a small fraction of described species, with major knowledge gaps for most organisms, including plants. Here, we highlight how digitised herbarium specimens can be used to accelerate and improve estimates of recent and ongoing plant extinctions.

Kinematics and Convergent Tectonics of the Northwestern South American Plate During the Cenozoic

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 7, July 2023., 2023
Abstract The interaction of the northern Nazca and southwestern Caribbean oceanic plates with northwestern South America (NWSA) and the collision of the Panama‐Choco arc (PCA) have significant implications on the evolution of the northern Andes. Based on a quantitative kinematic reconstruction of the Caribbean and Farallon/Farallon‐derived plates, we ...

The best of two worlds: ecology and evolution of ambophilous plants

Biological Reviews, Volume 98, Issue 2, Page 391-420, April 2023., 2023
ABSTRACT Ambophily, the mixed mode of wind and insect pollination is still poorly understood, even though it has been known to science for over 130 years. While its presence has been repeatedly inferred, experimental data remain regrettably rare. No specific suite of morphological or ecological characteristics has yet been identified for ambophilous ...

Preliminary rain rate statistics with one‐minute integration time for radio propagation uses in Venezuela

Electronics Letters, Volume 59, Issue 6, March 2023., 2023
Rain rate statistics for radio propagation applications collected with a 1‐min integration time in three locations of Venezuela are presented and analyzed for the first time in the country. Specifically, the WM and the annual cumulative distribution of rain rate were examined.

Behavioural responses by a bumble bee to competition with a niche‐constructing congener

Journal of Animal Ecology, Volume 91, Issue 3, Page 580-592, March 2022., 2022
Nectar robbing by flower‐biting bumble bees constitutes ecological niche construction if robbing holes persist and intensify nectar competition experienced by non‐biting, bystander flower visitors. In response, bystanders can tolerate robbing, switch plant species or adopt robbing, perhaps partially compensating for exploitative competition associated ...

SARS‐CoV‐2 infection and venous thromboembolism after surgery: an international prospective cohort study

Anaesthesia, Volume 77, Issue 1, Page 28-39, January 2022., 2022
Summary SARS‐CoV‐2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri‐operative or prior SARS‐CoV‐2 were at further increased risk of venous ...

Timing of surgery following SARS‐CoV‐2 infection: an international prospective cohort study

Anaesthesia, Volume 76, Issue 6, Page 748-758, June 2021., 2021
Summary Peri‐operative SARS‐CoV‐2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS‐CoV‐2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020.

Habitat-dependent occupancy and movement in a migrant songbird highlights the importance of mangroves and forested lagoons in Panama and Colombia. [PDF]

Ecol Evol, 2019
We found that overwintering occupancy and movement are habitat‐dependent in a nonterritorial overwintering migrant bird. Warblers in mangroves and other wet habitats are least likely to experience local extinction as dry season progresses, and warbler abundance was highest in mature mangroves forests.
