Effective application of functional trait approaches to ecological questions requires understanding the patterns of trait variation within species as well as between them. However, few studies address the potential for intraspecific variation to occur on a temporal basis and, thus, for trait-based findings to be contingent upon sampling year. To quantify annual variation in the functional traits of grassland plant species, we measured specific leaf area, leaf dry matter content, plant height, and chlorophyll content in 12 shortgrass prairie plant species. We repeated these measurements across 4 years, both in long-term nitrogen addition plots and in corresponding control plots. Three …
First Reproductive Evidence For The Slender Glass Lizard (Ophisaurus Attenuatus) In Nebraska, Keith Geluso
First Reproductive Evidence For The Slender Glass Lizard (Ophisaurus Attenuatus) In Nebraska, Keith Geluso
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
The Slender Glass Lizard (Ophisaurus attenuatus) reproduces across parts of northern and central Kansas, but its distribution extends into southern Nebraska. In Nebraska, not a single aspect of reproductive activity has been reported for this species in the state. Herein, we report on the first documentation of reproduction in Nebraska. On 22 September 2021, we captured two hatchling Slender Glass Lizards at the Ash Grove Wildlife Management Area in Franklin County, Nebraska. We calculated that those individuals likely hatched around the first week of September. Presence and reproduction of Slender Glass Lizards at the study site likely was …
