Trace metals in microcrustaceans and Brazilian waterweed from a contaminated Chilean wetland using total reflection X-ray fluorescence spectrometry [PDF]
, 2012 The trace element content of individual copepod specimens and of the Brazilian water weed (Egeria densa) from a metal-contaminated wetland in Southern Chile were determined using total reflection X-ray fluorescence spectrometry. Sampling of the water and

First study on parasites of Hemibrycon surinamensis (Characidae), a host from the eastern Amazon region. [PDF]
, 2019 This study was the first investigation of communities and infracommunities of parasites of Hemibrycon surinamensis. All the fish collected in a tributary of the Amazon river were parasitized by one or more parasite species. The Brillouin diversity index (

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.ABSTRACT This study aimed to evaluate the antitumor activity of fractions rich in indole alkaloids extracted from the leaves of the species Tabernaemontana catharinensis. The chemical composition was analyzed using high‐resolution mass spectrometry (HRMS), which identified nine known indole alkaloids, including voacangine, voacangine hydroxyindolenine,

The use of a portable total reflection X-ray fluorescence spectrometer for trace element determination in freshwater microcrustaceans (Daphnia) [PDF]
, 2012 The suitability of a newly developed, portable total reflection X-ray fluorescence (TXRF) spectrometer (PicoTAX, Roentec, Berlin, Germany) to analyze trace elements in biological material was tested and compared with a stationary instrument (Spectrometer

Ecology and Evolution, Volume 16, Issue 4, April 2026.We evaluated the effects of the 2019 Brumadinho tailings‐dam collapse on neotropical otters (Lontra longicaudis) in Brazil's Paraopeba river using multi‐season occupancy models. Six years post‐collapse, otters showed high occupancy across impacted reaches.

Waterborne transmission largely contributes to the epidemiology of a plankton parasite
Ecology, Volume 107, Issue 3, March 2026.Abstract Understanding how parasites spread is crucial for preventing infections and predicting epidemic dynamics. These efforts are challenging for environment‐borne parasites because transmission is host density‐independent. We monitored the dynamics of Pasteuria ramosa, a common bacterial parasite of Daphnia magna with prolonged free‐living ...
