Data from: Lights out: the evolution of bacterial bioluminescence in Loliginidae

Frank E. Anderson, Alexis Bergman, Samantha H. Cheng, M. Sabrina Pankey & Tooraj Valinassab
Representatives of several metazoan clades engage in symbiotic interactions with bioluminescent bacteria, but the evolution and maintenance of these interactions remain poorly understood. Uroteuthis is a genus of loliginid squid (Cephalopoda: Loliginidae) characterized by paired ventral photophores (light organs) housing bioluminescent bacteria. While previous phylogenetic studies have suggested that Uroteuthis is closely related to Loliolus, a genus of non-bioluminescent species, this relationship remains unresolved. To illuminate Uroteuthis and Loliolus phylogeny and its implications for the...

Data from: No effect of seed source on multiple aspects of ecosystem functioning during ecological restoration: cultivars compared to local ecotypes of dominant grasses

Genetic principles underlie recommendations to use local seed, but a paucity of information exists on the genetic distinction and ecological consequences of using different seed sources in restorations. We established a field experiment to test whether cultivars and local ecotypes of dominant prairie grasses were genetically distinct and differentially influenced ecosystem functioning. Whole plots were assigned to cultivar and local ecotype grass sources. Three subplots within each whole plot were seeded to unique pools of...

Data from: Intraspecific variation among clones of a naïve rare grass affects competition with an invasive forb

David J. Gibson, Justin Dewey, Hélène Goossens & Misty M. Dodd
Intraspecific variation can have a major impact on plant community composition yet there is little information available on the extent that such variation by an already established species affects interspecific interactions of an invading species. The current research examined the competitiveness of clones of a globally rare but locally common native grass, Calamagrostis porteri ssp. insperata to invasion by Alliaria petiolata, a non-native invasive species. A greenhouse experiment was conducted twice over consecutive years in...
