Fig. 2 in Cephalopods From The Cretaceous/Tertiary Boundary Interval On The Atlantic Coastal Plain, With A Description Of The Highest Ammonite Zones In North America. Part 2. Northeastern Monmouth County, New Jersey

Fig. 2. Standard stratigraphic sequence of part of the Upper Cretaceous and Lower Tertiary succession in Monmouth County, New Jersey (reproduced from Olsson, 1987). In earlier interpretations (Olsson, 1963), the New Egypt Formation was also considered to be equivalent to parts of the Hornerstown and Navesink formations.

Geographic and temporal morphological stasis in the latest Cretaceous ammonoid Discoscaphites iris from the U.S. Gulf and Atlantic Coastal Plains

We examine temporal and spatial variation in morphology of the ammonoid cephalopod Discoscaphites iris using a large dataset from multiple localities in the Late Cretaceous (Maastrichtian) of the United States Gulf and Atlantic Coastal Plains, spanning a distance of 2000 km along the paleoshoreline. Our results suggest that the fossil record of D. iris is consistent with no within species net accumulation of phyletic evolutionary change across morphological traits or the lifetime of this species. Correlations between some traits and paleoenvironmental conditions as well as changes in the coefficient of variation may support limited population-scale ecophenotypic plasticity, however where stratigraphic data are available, no directional changes in morphology occur prior to the Cretaceous/Paleogene (K/Pg) boundary. This is consistent with models of 'dynamic' evolutionary stasis. Combined with knowledge of life history traits and paleoecology of scaphitid ammonoids, specifically a short planktonic phase after hatching followed by transition to a nektobenthic adult stage, these data suggest that scaphitids had significant potential for rapid morphological change in conjunction with limited dispersal capacity. It is therefore likely that evolutionary mode in the Scaphitidae (and potentially across the broader ammonoid clade) follows a model of cladogenesis wherein a dynamic morphological stasis is periodically interrupted by more substantial evolutionary change at speciation events. Finally, the lack of temporal changes in our data suggest that global environmental changes (such as those possibly related to the emplacement of the Deccan Traps Large Igneous Province) had a limited effect on the morphology of North American ammonoid faunas during the latest Cretaceous prior to the K/Pg mass extinction event.

Genomic variation in the Black-throated Green Warbler (Setophaga virens) suggests divergence in a disjunct Atlantic Coastal Plain population (S. v. waynei)

We used whole-genome resequencing to estimate genetic distinctiveness in the Black-throated Green Warbler (Setophaga virens)—including S. v. waynei—a putative subspecies that occupies a narrow disjunct breeding range along the Atlantic Coastal Plain. Despite detecting low-global differentiation (FST = 0.027) across the entire species, the principal components analysis of genome-wide differences shows the main axis of variation separates S. v. waynei from all other S. v. virens samples. We also estimated a low-migration rate for S. v. waynei, but found them to be most similar to another disjunct population from the Piedmont of North Carolina, and detected evidence of a historical north-to-south geographic dispersal among the entire species. New World wood warblers (family: Parulidae) can exhibit strong phenotypic differences among species, particularly, in song and plumage; however, within-species variation in these warblers—often designated as subspecies—is much more subtle. The existence of several isolated Black-throated Green Warbler populations across its eastern North American breeding range offers an excellent opportunity to further understand the origin, maintenance, and conservation status of subspecific populations. Our results, combined with previously documented ecological and morphological distinctiveness, support that S. v. waynei be considered a distinct and recognized subspecies worthy of targeted conservation efforts.

North American Coastal Plain PRISMA Surface Reflectance and Mixture Residual Spectra

The data available here include the training and validation spectra for creating the models for the currently unpublished manuscript “Classifying Plant Communities in the North American Coastal Plain with PRISMA Spaceborne Hyperspectral Imagery and the Spectral Mixture Residual." Spectral data contain both raw surface reflectance (SR) and spectral mixture residual spectra (MR) transformed with endmembers and code from Sousa et al.'s (2022) paper titled "The spectral mixture residual: A source of low‐variance information to enhance the explainability and accuracy of surface biology and geology retrievals." Spectra represent averaged 60 m x 60 m areas (2 x 2-pixel window) located in the Red Hills (RH), the Jones Ecological Research Center (JERC), the Ordway-Swisher Biological Station (OSBS), and the Disney Wilderness Preserve (DSNY). To maintain the confidentiality of private property information on behalf of landowners, the locations of the RH plots were intentionally obscured, considering the nature of the region. See manuscript for further details.
