Fish Assemblage Shift Following Abrupt Seagrass Loss in a Southwest Florida Tidal CreekNARA Subscribed
Phase shifts can occur in ecosystems because of external stressors. Such transitions from one state (e.g., clear water, seagrass) to another (e.g., phytoplankton blooms, bare substrate) continue to be documented worldwide. In estuaries, stressors related to urban and suburban development are often implicated in phase shifts, including altered hydrology and eutrophication. Tidal creeks may be especially prone to phase shifts as...
Regulation of PDGF-BB signaling in placental pericytes by soluble PDGFRβ isoforms: implications for fetoplacental vascular developmentNARA Subscribed
Vascular remodeling within the developing fetus and placenta is essential for supporting the growth and function of emerging tissues and organs. Pericytes (PCs) play a central role in stabilizing and maturing microvascular networks by extending along endothelial cells (ECs) and reinforcing vessel integrity. In the placenta, as in other organs, PC–EC communication is mediated in part by platelet-derived growth factor-BB (PDGF‑B...
Multi‐Omic Assessment of Microbial Communities and Their Polyketide Biosynthetic Potential Across Abyssal SedimentsNARA Subscribed
Microbially‐derived polyketides include some of today's most valuable medicines, yet their discovery has focused on a narrow subset of Earth's microbial biodiversity. Although understudied biomes such as marine sediments have been targeted, these efforts have focused on samples collected from shallow waters. In contrast, abyssal marine sediments (4000–6000 m), which comprise > 80% of the ocean floor, remain poorly explored. Th...
Whole blood transcriptional signatures of age and survival identified in long life family and integrative longevity omics studiesNARA Subscribed
Although aging is a universal event, some individuals are able to achieve extreme longevity. The Long-Life Family Study (LLFS) enrolls participants from families enriched with long-lived individuals, serves as a valuable dataset for studying ageing phenotypes and identify potential intervention targets. We analyzed the association between age at blood draw and 16,284 RNAseq-based blood transcriptomic data from 2,167 LLFS parti...
Exploring the data demands and global opportunities for reconstructing morphological responses to climate changeNARA Subscribed
There is growing evidence that morphological change is a widespread response to the warming climate. The empirical basis for understanding this process has, to date, largely been correlative analyses of morphological time series. However, it is not clear what constitutes sufficient temporal sampling for assessing long-term morphological change. We analyzed two long-term high-quality morphological datasets, one including 33 spe...
The relationship between nutrient supply from resident fishes and the growth, condition, and thermal tolerance of coralsNARA Subscribed
Coral reefs are in decline and face mounting stressors such as increasing sea temperatures, making it crucial to understand natural mechanisms that support coral health. Planktivorous damselfishes share tight associations with live corals and excrete inorganic forms of nitrogen and phosphorus that are typically limited in oligotrophic coral reef systems. Although these nutrient types are often beneficial to coral growth and ov...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Synchrony and Tail‐Dependent Synchrony Have Different Effects on Stability of Terrestrial and Freshwater CommunitiesNARA Subscribed
Aim Global change can impact the stability of biological communities by affecting species richness and synchrony. While most studies focus on terrestrial ecosystems, our research includes both terrestrial and aquatic realms. Previous works measure overall community synchrony as co‐variation among co‐occurring species, ignoring the tail dependence—when species fluctuate together at extreme abundance levels. We used community ti...
LandFrag : A Dataset to Investigate the Effects of Forest Loss and Fragmentation on BiodiversityNARA Subscribed
Motivation The accelerated and widespread conversion of once continuous ecosystems into fragmented landscapes has driven ecological research to understand the response of biodiversity to local (fragment size) and landscape (forest cover and fragmentation) changes. This information has important theoretical and applied implications, but is still far from complete. We compiled the most comprehensive and updated database to inves...
Secondary contact erodes Pleistocene diversification in a wide‐ranging freshwater mussel (Quadrula )NARA Subscribed
The isolated river drainages of eastern North America serve as a natural laboratory to investigate the roles of allopatry and secondary contact in the evolutionary trajectories of recently diverged lineages. Drainage divides facilitate allopatric speciation, but due to their sensitivity to climatic and geomorphological changes, neighboring rivers frequently coalesce, creating recurrent opportunities of isolation and contact th...
AVOTREX : A Global Dataset of Extinct Birds and Their TraitsNARA Subscribed
Motivation Human activities have been reshaping the natural world for tens of thousands of years, leading to the extinction of hundreds of bird species. Past research has provided evidence of extinction selectivity towards certain groups of species, but trait information is lacking for the majority of clades, especially for prehistoric extinctions identified only through subfossil remains. This incomplete knowledge potentially...
