Gelatinous animals have been historically viewed as trophic dead-ends. However, there are increasing data showing these organisms being consumed by diverse predators and demonstrate they play an important role in ecosystem functioning. Here we document the Ocypode quadrata (Fabricius, 1787) scavenging on stranded Physalia physalis (Linnaeus, 1758) at Sergipe and Bahia, tropical Brazil (11° and 14° Lat. S), based on Instagram® posts. These findings highlight the potential of social media to complement the information provided by traditional academic sources. We also suggest that this predatory interaction is probably more common than reported in the literature, perhaps due to methodological constraints of stomach content analyses, which may overlook the consumption of gelatinous animals by ghost crabs.

The movement of species is among the most serious environmental threats of the new millennium, as the transplantation of species beyond their native or historical range has intensified in the last five decades. Traditionally, studies on bioinvasions have focused on species that have been introduced, deliberately or accidentally, to biogeographic regions where they did not previously occur. However, less attention has been given to species movement to novel areas within the same biogeographic region. Our research group, the South America Introduced Molluscs Specialists, analyzed potential cases of native South American mollusc species introduced deliberately or accidentally beyond their natural range within South America. To achieve this, it is key to differentiate between anthropogenic processes and passive responses to environmental conditions. We considered the past and current spatial distribution of species, analyzed known or putative vectors, and discuss the impacts of taxonomic and nomenclatural knowledge. Based on the evidence currently available, we propose different scenarios to explain observed changes in mollusc distributions within South America. Seventeen transplanted mollusc species (TMS) were recognized, considering marine, freshwater, and terrestrial environments. Of the 189 South American ecoregions 31 were occupied by transplanted species, but this proportion varied by environment: 10 of 28 marine ecoregions, 12 of 52 freshwater ecoregions, and 9 of 109 terrestrial ecoregions. The ecoregions with TMS are generally located in the peripheral zones of the continent. Those with the highest number of TMS were the Southern Caribbean (three species) in the marine environment, the Central Andean Pacific Slopes (three species) in the freshwater environment, and the Alto Paraná Atlantic forests (two species) in the terrestrial environment. The number of unintentionally moved TMS is greater than those moved intentionally. The transplantation process is similar to the introduction and settlement process of non-native mollusc species, and so is their impact.

In the present work, we have synthesized new molecular hybrids consisting of porphyrin ring system connected at the meso positions with phenyl groups and/or, through p-phenylene linkers, with 1,4-dihydropyridine or pyridine moieties. In general, the directed use of dihydropyridine aldehyde, under time-modified Adler–Longo procedures, gave the best overall yields of the following meso-substituted dihydropyridine-porphyrins of general formula A1B3, A2B2, or A4, where A stands for phenyl-dihydropyridine and B for phenyl substituents. The corresponding meso-substituted pyridine-porphyrin hybrids were obtained from oxidation of the dihydropyridineporphyrins with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone. The UV-vis spectra bands of the A4 dihydropyridine-porphyrin were unexpectedly red-shifted, having a rhodoporphyrin Q-bands profile. It was also found that an increased production of 1O2 correlates with a higher number of dihydropyridine or pyridine moieties in the hybrid molecule. All porphyrin hybrids were considered adequate candidates to be employed in photodynamic therapy.
