USGS scientists have named the two new species of bass. This important discovery adds to the biodiversity of freshwater ecosystems in the southeastern United States, one of the world’s natural biodiversity hotspots. Bud Freeman and Mary C. Freeman, both from the Odum School of Ecology at the University of Georgia, co-authored the research. It was described in detail in the scientific journal Zootaxa, shortly after official recognition of its discovery. The find provides important baseline information about their evolutionary history and conservation needs.
In the early 1980s, Bud Freeman was the first to identify the newly recognized species, Micropterus pucpuggy, or Bartram’s bass. Here’s why he thinks this research is so important. He stated, “You’re laying the baseline for the future,” emphasizing the significance of understanding these species for future ecological studies and conservation efforts.
The New Species Unveiled
Of the new species recognized, Bartram’s bass (Micropterus pucpuggy) and Altamaha bass (Micropterus calliurus). Using their new characteristics and habitats as a baseline, the study sheds light on the species’ role within the aquatic ecosystem. The Bartram’s bass pays tribute to the Floridians who crossed paths with Bartram, with “Puc Puggy” translating to “Flower Hunter” in Seminole-Creek language. This association with local history highlights the cultural importance of biodiversity.
The Altamaha bass displays shimmering pale gold scales edged in olive. Its sides are marked with dark brown blotches, and the margins of its fins are bright orange. These unique physical features further distinguish it from the other black bass species. They are of tremendous interest to anglers and researchers. Both species of fish are capable of growing over six feet long. Max length of Bartram’s bass is 14 inches, but Altamaha bass can be even bigger, up to 15 inches.
Research Methodology and Findings
To back up their claims, the researchers put together a detailed dataset combining more than 570 individuals across multiple bass species. Over 100 conspecific animals were cited in the description documentation for the two new species. This highly selective process allowed researchers to perform a much deeper analysis of genetic and morphological characteristics. In doing so, they developed a much better picture of these fish’s evolutionary tree.
Bud Freeman, director of Sonoran Institute’s Colorado Plateau program, was the study’s chief author. He is a senior public service associate emeritus at the Odum School of Ecology. His extensive knowledge of freshwater ecology was instrumental to this innovative research. Co-authors Mary C. Freeman and John P. Wares, both of the Odum School of Ecology and UGA Department of Genetics, provided important perspectives on the paper’s genetic analysis. Their critical feedback helped develop the research and sharpened the research’s findings.
Implications for Conservation
The discovery of these new species is vital for the ongoing protection of our freshwater ecosystems. As human activities increasingly threaten aquatic habitats, understanding the biodiversity within these environments becomes essential. The documentation of Bartram’s bass and Altamaha bass not only adds to the scientific community’s knowledge but emphasizes the need for protective measures to ensure their survival.
Freeman’s claim about establishing a baseline for future research preserves the value of this study, setting a precedent for shaping conservation policies. By establishing a clear understanding of these new species, ecologists can better advocate for necessary protections and resources to maintain healthy aquatic ecosystems.
