While recovering 2 GPS radio transmitters in the Katy Prairie region of Southeast Texas, we excavated 2 active Plains Spotted Skunk burrows. Herein, we describe the schematics of 1 system that likely was excavated initially by a Geomys breviceps (Baird's Pocket Gopher) and the general schematics of a second burrow system frequently used by a different radio-collared individual. Both systems contained an obstructed entrance and a detritus-filled central cavity and were in locations higher in elevation than the surrounding matrix. Our observations further confirm the 3 requirements for Plains Spotted Skunk diurnal rest-location usage—protection from predation, thermoregulatory benefits, and protection from inclement weather—while providing additional insight into the intricacies of the burrow system itself. Further research into the structure of Spilogale burrows is needed to improve future conservation and management efforts of the genus.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"42 1","pages":"352 - 363"},"PeriodicalIF":0.6,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74128288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Black Spiny-tailed Iguana is considered one of the larger, heavier iguanid species, identified by its coloration and a series of enlarged whorls of spiny scales on the tail. Despite harvest rates for human consumption and the pet trade, Black Spiny-tailed Iguana is currently considered a species of least concern in their native range. There have been several introductions outside of their native range, many of which have become established due to their generalist nature. In Florida, Black Spiny-tailed Iguana was first introduced in 1979 and has been reported in 24 counties. Early removal efforts of other introduced iguanids such as Ctenosaura pectinata (Mexican Spiny-tailed Iguana) and Iguana iguana (Green Iguana) could serve as case studies to develop and implement eradication and management plans for this species. We provide a comprehensive summary of natural history findings on Black Spiny-tailed Iguana, including management methods and potential ecological impacts as an invasive species in the southeastern United States.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"5 1","pages":"292 - 314"},"PeriodicalIF":0.6,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87303667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A vegetation index (measure of the amount of vegetation) was a positive predictor of species richness for all suburban adapters and abundance for 3 species of suburban adapters (Mimus polyglottos [Northern Mockingbird], Cardinalis cardinalis [Northern Cardinal], Thryothorus ludovicianus [Carolina Wren]). Building area was a negative predictor of species richness for all suburban adapters and abundance for Northern Mockingbird.

Two exotic urban invaders (House Sparrow, European Starling) and 4 suburban adapters (Northern Mockingbird, Northern Cardinal, Carolina Wren, Zenaida macroura [Mourning Dove]) were also among the most abundant species (i.e., those whose average counts were ≥5 birds) and were resident species that nested within the plot the previous breeding season.

Nocomis leptocephalus (Bluehead Chub) is a widespread minnow (Actinopterygii: Leuciscidae) native to small- to medium-sized streams in the Atlantic slope of the southeastern United States. By constructing large gravel-mound nests in pools for spawning, Bluehead Chubs are common ecosystem engineers that transport and concentrate gravel to form unique structures on the benthoscape. These nests are occupied by a diversity of benthic taxa and can persist up to 6 months before being destroyed by winter floods. In this study, we surveyed benthic assemblages occurring on chub nests and a similar volume of paired ambient substrate, and identified individuals to the genus or family level. Mixed-effects models indicated that overall counts, taxa richness, and Shannon diversity of benthic assemblages were similar between nests and ambient substrate. However, canonical correspondence analysis revealed differences in taxonomic composition between nests and ambient substrate. Several riffle-associated taxa occurred uniquely in chub nests, while many other taxa were found only in paired samples. Understanding the temporal and spatial scales at which the chub nest –insect interaction is relevant will be important for identifying the role of ecosystem engineering by chubs for structuring benthic assemblages.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"23 1","pages":"254 - 271"},"PeriodicalIF":0.6,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83056469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During a recent study of fishes in this watershed, we observed 5 mussel species at 12 sites: Lampsilis hydiana (Louisiana Fatmucket), Sagittunio subrostratus (Pondmussel), Pyganodon grandis (Giant Floater), Toxolasma texasiense (Texas Lilliput), and Uniomerus declivis (Tapered Pondhorn).

The least abundant species was Giant Floater, with 1 individual at 1 site. There was evidence of recent recruitment in 2 species, Tapered Pondhorn (median total length [TL] = 71 mm; min–max = 28–99 mm), and Texas Lilliput (median TL = 21 mm; min–max = 13–40 mm).

Significant resources and financial investments are often directed towards invasive species management (ISM) to prevent future introductions, to remove smaller populations, and to contain expanding populations. While prevention is the most important goal of ISM, focus may shift to removal (eradication) when prevention fails. Eradication attempts are costly and have not been inclusive of all invasive populations. These efforts are inherently difficult because they require an abundance of resources, must be executed before the population expands, can be disrupted by public opposition, and often require years of monitoring to confirm success. Regardless, even failed eradication attempts provide important lessons to potentially improve future eradication efforts. This review of 20 case studies in Florida assesses successful and failed eradication attempts to identify common factors that contributed to each outcome. More than half of the detailed failed eradication attempts either lacked communication from or were outright disrupted by stakeholders. Most successful eradications targeted fish or small mammals and removed <200 individuals. Nearly half of the successful eradications occurred on islands or within isolated bodies of water. Despite the abundance of invasive herpetofauna in Florida, there has yet to be a documented successful eradication effort targeting these species. While many barriers exist to publishing eradication outcomes, future eradication efforts should prioritize documentation to provide guidance to similar efforts. Future research should address the role of media coverage and outreach efforts regarding eradication success, especially efforts targeting charismatic species.","PeriodicalId":49490,"journal":{"name":"Southeastern Naturalist","volume":"2 1","pages":"222 - 253"},"PeriodicalIF":0.6,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90673603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
