Mississippi River Baton Rouge water quality
<p>We investigated how physical and chemical factors affect Chlorophyll a concentrations in the Mississippi River, the largest river in North America, by sampling 878 times from February 1997 to December 2018 near its terminus at Baton Rouge, Louisiana. Measured values included temperature, light (secchi disk), suspended sediments, and nutrients (nitrate+nitrite, phosphate, TP, TN, ammonium, silicate) that may affect phytoplankton communities. The data are available for unrestricted use.</p>
Nipponaclerda biwakoensis infestation of Phragmites australis in the Mississippi River Delta, USA: Do fungal microbiomes play a role?
<p>Recently, significant die-back of nonnative common reed, <i>Phragmites australis,</i> has been reported in the Mississippi River Delta (MRD), Louisiana, USA. This dieback has been attributed to an invasive scale insect, <i>Nipponaclerda biwakoensis</i>. We test whether fungi are involved in the recent infestation by this insect and subsequent die-offs of <i>Phragmites australis</i>. Several haplotypes of <i>P. australis</i> occur in the MRD, and the European (M) and Delta (M1) haplotypes appear to experience differing levels of <i>N. biwakoensis </i>infestation. We tested whether these haplotypes differed in their fungal microbiomes in both their leaf and stem tissues, and whether differences in fungal community composition were linked to the level of infestation using a metabarcoding Internal Transcribed Spacer (ITS) amplicon sequencing approach. Our analyses showed differences in fungal community composition and diversity between haplotypes and tissue types, but none of these differences were directly correlated with <i>N. biwakoensis</i> infestation severity. However, we did find that the European haplotype hosted higher putative pathogen loads in stem tissues compared to the Delta haplotype, which may confer resistance to herbivory, though it is possible that differences in infestation between haplotypes are due to morphology.</p>

FIGURE 23 in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 23. Possible specimen of Desmognathus pascagoula (AUM 10543) from near Tensaw, Baldwin Co., Alabama in dorsal (a) and ventral (b) views. Key features suggesting conspecificity with the Pascagoula populations are a relatively blunt or brachycephalic snout; distinct postocular stripe (faded in preservative, but of an apparently bright color in life); distinct dorsal color pattern; jagged but noticeable ventrolateral and lateral "portholes" on the trunk and tail(appearing as light areas devoid of melanin); ventral melanophores in the "stellate" condition; and heavily keeled, "fin-like" or "blade-like" tail with distinct dorsal coloration.
FIGURE 21 in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 21. Larger specimen (MMNS 19993/RAP1112) of Desmognathus valentinei from headwaters of West Creek, Harrison Co., Mississippi, beginning to showing typical adult coloration of "dark auriculatus" sensu Valentine (1963) more typical of southeastern Mississippi populations. Note the more uniform and darker dorsal coloration and more brightly contrasting "portholes" in all three rows on the trunk.
FIGURE 22 in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 22. Large specimen (MMNS 19994/RAP1113) of Desmognathus valentinei from headwaters of West Creek, Harrison Co., Mississippi, showing typical adult coloration of "dark auriculatus" sensu Valentine (1963). Note the uniform melanistic dorsal coloration and brightly contrasting ventrolateral "portholes" on the trunk, nearly indistinguishable postocular stripe, and strongly keeled "fin-like" or "blade-like" tail, with lateral row of "portholes" barely visible.
FIGURE 19 in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 19. Small specimen (MMNS 19990/RAP1109) of Desmognathus valentinei from Thompson Creek, Wayne Co., Mississippi, showing typical juvenile form and color of "pale auriculatus" sensu Valentine (1963), notably a blunt snout; indistinct postocular stripe; indistinct dorsal color pattern; distinct ventrolateral and lateral "portholes" on the trunk and tail; and distinctly keeled, "fin-like" or "blade-like" tail (partially regrown).
FIGURE 20 in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 20. Large adult specimen (MMNS 19991/RAP1110) of Desmognathus valentinei from Thompson Creek, Wayne Co., Mississippi, showing typical adult coloration of "pale auriculatus" sensu Valentine (1963). Note overall distinctiveness in body form and coloration from D. pascagoula, including muted coloration of the postocular stripe, girth of the trunk and tail, distinctiveness of all three rows of "portholes" on the trunk, and lack of distinct dorsal color pattern.
FIGURE 16 in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 16. Ventral view of the Ward Bayou paratype (MMNS 19623/JYL78) of Desmognathus pascagoula in life. Note the darkened "stellate" condition of the ventral melanophores, as in nearby populations of D. valentinei (see Means et al. 2017). The jagged but prominent ventrolateral line of portholes is clearly visible here on the body, as is the lateral row of "portholes" on the tail.
FIGURE 14 in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 14. The holotype (USNM 596040/RAP1106) of Desmognathus pascagoula in preservative in dorsal (a) and ventral (b) views. Tick marks on ruler are in mm.
FIGURE 15 in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 15. The Ward Bayou paratype (MMNS 19623/JYL78) of Desmognathus pascagoula in life. Note distinct dorsal color pattern, the irregular lateral "portholes" on the trunk and tail, and the larger ventrolateral "portholes."
FIGURE 17. A in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 17. A Grand Bay paratype (AUM 45885/RAP1107) of Desmognathus pascagoula in life on isolated (a) and naturalistic (b) backgrounds. Note the bright orange postocular stripe shared by all adult specimens, and the resemblance to the Ward Bayou paratype in terms of the distinct coloration on the dorsal surface of the tail, dark overall coloration, and visibility of the ventrolateral portholes on the body and lateral row of "portholes" on the tail.
FIGURE 18 in A new, narrowly endemic species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Gulf Coastal Plain of Mississippi and Alabama
FIGURE 18. Additional specimen (DAB11479) of Desmognathus pascagoula from the Grand Bay locality, showing variation in color pattern. Note overall lighter coloration compared to the paratypes, though still exhibiting a bright orange postocular stripe, relatively indistinct dorsolateral "portholes," two-toned lateral coloration and jagged ventrolateral row of "portholes," reddish-orange stripe on the dorsal surface of the tail, and increased prominence of lateral "portholes" on the tail, which is fat, keeled, and blade-like towards the tip (partially regenerated).
