Frontiers in Marine Science, 2021 Black carbon (BC) is believed to be refractory and thus affects the timescale of organic carbon conversion into CO2 and the magnitude of the sink of CO2. However, the fate of BC in the oceans remains poorly understood. Here, 210Po and 210Pb were measured

It’s All about the Zone: Spider Assemblages in Different Ecological Zones of Levantine Caves
Diversity, 2021 Caves possess a continuum of ecological zones that differ in their microhabitat conditions, resulting in a gradient of nutrients, climate, and illumination.

Frontiers in Marine Science, 2022 Coastal acidification has been widely investigated in terms of its rationale and ecological effects in the last decade. However, the driving mechanism for acidification in open seawater, especially in mesopelagic water, is still poorly understood.

Upper-ocean flux of biogenic calcite produced by the Arctic planktonic foraminifera Neogloboquadrina pachyderma [PDF]
Biogeosciences, 2022 With ongoing warming and sea ice loss, the Arctic Ocean and its marginal seas as a habitat for pelagic calcifiers are changing, possibly resulting in modifications of the regional carbonate cycle and the composition of the seafloor sediment.

Identifying zooplankton community changes between shallow and upper-mesophotic reefs on the Mesoamerican Barrier Reef, Caribbean [PDF]
PeerJ, 2017 Mesophotic coral ecosystems (MCEs, reefs 30–150 m) are understudied, yet the limited research conducted has been biased towards large sessile taxa, such as scleractinian corals and sponges, or mobile taxa such as fishes.

In an immunological twilight zone
Proceedings of the National Academy of Sciences, 1998 Early in their evolution, perhaps during their transition from Agnatha (jawless fish) to Gnathostomata (jawed animals), vertebrates committed as much as 1% of their protein-encoding genome to a new system of defense against parasites (1). Central to this anticipatory (adaptive) immune system (2) are three types of antigen receptor—immunoglobulin (Ig ...

Graph Theory-Based Sequence Descriptors as Remote Homology Predictors
Biomolecules, 2019 Alignment-free (AF) methodologies have increased in popularity in the last decades as alternative tools to alignment-based (AB) algorithms for performing comparative sequence analyses. They have been especially useful to detect remote homologs within the
