Summary: The northwestern corner of South America is a highly complex geodynamic zone, where the convergence of South America, Nazca, and Caribbean plates leads to heterogeneity and complexity in the lithospheric structure. This study presents depth-migrated profiles of teleseismic receiver function analysis, providing better understanding of the lithospheric discontinuities and intracrustal features. The results show an updated crustal thickness map, differences in the northernmost part of the cordilleran system, and support the segmentation of the subduction system with multiple slab segments.

Summary: The dynamics of terrestrial water storage play a crucial role in various natural and social phenomena, including water security and environmental sustainability. Using GRACE data, this study focused on the Magdalena-Cauca river basin in northwestern South America and found a gradual depletion of both terrestrial water storage and groundwater storage in the basin since the end of 2010. The spatial patterns of water depletion within the basin correspond closely to the periods between La Nina and El Nino extreme phases of ENSO.

Summary: The Tampanchi Ultramafic-Mafic Complex (TUMC) in Ecuador is an oval-shaped intrusive body composed of wehrlite and olivine-hornblende clinopyroxenite, crosscut by hornblende gabbros, diorite, and granite. Geochemical and isotopic data indicate subduction-related parental liquids and a mantle source metasomatized by subducted crustal components. The emplacement and crystallization of the complex occurred at intermediate to shallow crust levels and around 75-76 million years ago. These findings support the existence of magmatic arc activity and double subduction at the continental margin of South America during the late Cretaceous.

Summary: Hoverflies in paramo ecosystems are important in providing ecosystem services and can serve as bioindicator species for montane habitats. Conservation efforts for these habitats are crucial to protect the biodiversity and ecological services provided by hoverflies in the face of threats from global warming and anthropogenic activities.

Summary: This study describes a new genus and species of March fly, Protopenthetria skartveiti gen. et sp. nov., from mid-Cretaceous Burmese amber. The well-preserved male specimen provides evidence of the morphology of Bibionidae in the Mesozoic, highlighting the high diversity of the Burmese amber biota. A key to all known genera and species of Bibionidae from Burmese amber is also provided.

Summary: A large amount of research has focused on commercializing carotenoids produced by Haematococcus, but without a proper phylogenetic assessment. The existence of cryptic diversity in the genus can complicate pigment studies. By analyzing molecular markers and conducting morphological studies, we identified a new species, H. privus, exclusively found in North America. Our findings also suggest that certain morphological traits can be helpful in distinguishing different Haematococcus lineages.

Summary: This study presents a new multigene phylogenetic analysis to support the concept and monophyly of a new genus, containing eight species, seven of them being described as new to science. The phylogenetic analysis reveals that the new genus is the sister group of Claustropyga based on four gene fragments (28S, 18S, 16S and COI).

Summary: The first named species of Scatopsidae, Hoploscatopse prisca gen. et sp. nov., is described and illustrated in this study. The fossil specimen was found in mid-Cretaceous amber from northern Myanmar. The systematic placement of the new genus is briefly discussed and it is tentatively placed in Scatopsidae incertae sedis, pending the discovery of additional similar taxa in the Cretaceous.

Summary: Tropical forests are known for their high biodiversity, but quantifying the abundance and species richness of insects in these forests is a challenge. This study examined the variability of insect fauna across a vertical canopy gradient in a tropical forest in the Amazon. The researchers collected insect samples using traps set at different heights and found that certain insect orders were more abundant at the ground level, while others were more abundant in the upper levels of the canopy. They also identified a large number of species that were not sampled at the ground level, suggesting the need for a more comprehensive understanding of the three-dimensional distribution of insect diversity in tropical forests for effective conservation strategies.
