Empirical data on growth and residency of juvenile Pacific salmon in North America estuaries
<p>Dataset compiling empirical data on estuarine growth and residency of Pacific salmon in North America. We conducted a systematic literature review to create this database, starting with a literature search in <i>Web of Science Core Collection</i> through Simon Fraser University's library proxy on April 24th, 2018, using the search parameters (salmon, Oncorhynchus) AND (estuary*) AND (residen* OR growth OR survival OR mortality), which returned 681 results (these results were presented in Arbeider 2018). We updated the search on March 29th, 2020, which produced 24 additional papers published after April 2018, and again on July 7th, 2022 which yielded another 31 papers published since March 2020. From these results, we extracted papers that research Pacific salmonids and whose study estuary was in North America. From this reduced list of papers, we extracted growth and residency parameters, as well as other relevant data. For complete methods please refer to:</p><p>Arbeider, M. et al. (In press).

Fig. 3 in The first possible remingtonocetid stem whale from North America
Fig. 3. Paleogeographic reconstructions and distributions of Eocene cetaceans. A. Ypresian, reconstructed at 52 Ma. B. Lutetian, reconstructed at 45 Ma. C. Bartonian, reconstructed at 40 Ma. D. Priabonian reconstructed at 36 Ma. Data are derived from occurrences in the Paleobiology Database and includes every published occurrence of archaeocete cetaceans (Uhen 2020).
Fig. 2. A in The first possible remingtonocetid stem whale from North America
Fig. 2. A. Remingtonocetus sp. (IITR-SB 2630) from Lutetian; Kachchh, India; right P4. B.?Remingtonocetidae indet. (USNM 449550) from Lutetian– Bartonian; Martin Marietta Quarry (formerly Superior Stone Quarry), near Castle Hayne, North Carolina, USA. Shown as if it were an upper premolar for comparison, but it may also represent a lower premolar as well. Note the extreme narrowness of the tooth. In lateral (A2, B2), medial (A1, B1), and occlusal (A3, B3) views.
Fig. 1 in The first possible remingtonocetid stem whale from North America
Fig. 1. PCA ordinations of differences in tooth morphology for sampled archaeocetes. This plot includes data from both adult and deciduous premolars. The numbers next to the axis labels indicate the percentage of explained variation in morphology for that axis. The tooth shapes around each point represent the outline generated using the harmonic coefficients produced by elliptic Fourier analysis to achieve 99.9% harmonic power. See SOM: table 1 for a list of included specimens.

FIGURE 2 in Fossil snakes of the Penny Creek Local Fauna from Webster County, Nebraska, USA, and the first record of snakes from the Early Clarendonian (12.5-12 Ma) of North America
FIGURE 2. Composite time-stratigraphic chart of the Neogene of Nebraska correlated with the number of snake genera presently identified from the Central Great Plains for each North American Land Mammal Age (NALMA) substage. Abbreviations: He (Hemingfordian), Ba (Barstovian), Cl (Clarendonian), Hh (Hemphillian). Each point on the snake richness chart is summarized for each substage at that substage's midpoint, and is not necessarily correlated with a particular rock unit on the right.Species richness values include fossils from the entire Central Great Plains region, while localities from Nebraska specifically and discussed in this study are listed at each substage point and come from the rock units to the right. The star represents the data from this study, which updates the previous lack of data from Cl1 across North America (represented by the gray hashed line) with data from UNSM Wt-13B. NALMAs and substages are correlated with time based on data and figures from Tedford et al. (2004). Rock Units are adapted from Joeckel et al. (2017) and Tedford et al. (2004). Snake generic richness is modified and updated from Jacisin et al., 2015).

FIGURE 15 in Comparison of Miocene to early Pleistocene-aged Castor californicus (Rodentia: Castoridae) to extant beavers and implications for the evolution of Castor in North America
FIGURE 15. Comparison of the skull and dentary of extant Castor canadensis (MVZ 80744) and C. fiber (USNM 248154) to fossil C. californicus (USNM 26154). Note that the North American species C. canadensis and C. californicus share shorter nasals, wider occiput, and more posteriorly positioned orbits than Eurasian C. fiber; both also display more anterior placement of the anterior margin of the pterygoid insertion and greater spread of the posterior processes (coronoid, condylar, angular) than C. fiber.

FIGURE 14. Variation line graph calculated by coefficients of variation with sample size correction for Castor canadensis and C. californicus postcranial measurements. Note that C. fiber is excluded due to limited sampling. Castor canadensis and C. californicus both contains high levels of variation in postcranial elements. See Table 17 for descriptive statistics, coefficients of variation, and ANOVA results.
