Rays of the family Rhinopteridae Jordan & Evermann, 1896 are highly migratory and widely distributed in warm tropical and temperate waters. Along the Brazilian coast, the presence of two species has been recorded: Rhinoptera bonasus Mitchill, 1815 and Rhinoptera brasiliensis Müller, 1836. These stingrays are commonly caught as bycatch in trawl fisheries, however, the two species lack distinctive external morphological features...

Aim By moving beyond traditional biome‐centric approaches to sample continuously across a massive ecotone, we investigate how species richness, community composition, and dominance of woody plants change across a strong longitudinal precipitation gradient and identify thresholds in water availability that drive shifts in community assembly between tropical dry forests and rainforests. Location A longitudinal precipitation grad...

Island regions are particularly susceptible to the impacts of climate change, which affect key sectors such as agriculture, water resources, and human activities. The observed trends of rising temperatures, decreasing precipitation, altered evapotranspiration patterns, and increasing pressure on water resources contribute to shifts in the aridity levels of various territories. This study focuses on the Canary Islands as a case...

Reverse osmosis is widely applied as an advanced treatment technology due to its high efficiency in removing organic micropollutants from wastewater. However, this process inevitably produces a residue with a high contaminant load, posing environmental challenges and requiring effective post-treatment strategies. In this study, the photoperoxidation process was investigated for the degradation of six pharmaceuticals (acetamino...

Introduction Male hypogonadism, including age-related and functional forms, is characterized by insufficient testosterone production often associated with obesity and metabolic comorbidities. Testosterone replacement therapy (TRT) increases serum testosterone but suppresses spermatogenesis and may cause adverse effects. Selective estrogen receptor modulators (SERMs), such as clomiphene citrate, have emerged as an alternative a...

To date, research on heat extremes has primarily focused on acute events such as heatwaves. However, many regions of the globe currently face a heat hazard that can persist for months at a time. We call this hazard ‘chronic heat’ and define it here as potentially dangerous heat that lasts for 90 days or more per year. Analyzing 30 years (1993–2023) of global weather station data using three complementary metrics, this study re...

Due to the poor solubility of iron (III) and strong regional differences in terrestrial, riverine or airborne input, iron is a limiting micronutrient in much of the world ocean. Because of increasing living standards and climate change, rainfall is becoming more intermittent, which exacerbates drought conditions. As a result, seawater desalination has a vital and growing role in providing drinking water in many hot and arid re...

This article is a celebration of the life and work of Carl J. Carrano who, from a childhood in Long Island, New York, built a career in bioinorganic chemistry, especially in the context of metal uptake and halogen metabolism in microbes and marine organisms.
