The Role Of Red Leaf Coloration In Prey Capture For Pinguicula Planifolia, Jenna Annis, Janice Coons, Charles Helm, Brenda Molano-Flores
The Role Of Red Leaf Coloration In Prey Capture For Pinguicula Planifolia, Jenna Annis, Janice Coons, Charles Helm, Brenda Molano-Flores
Faculty Research & Creative Activity
Anthocyanins in the leaves of carnivorous plants are suggested to play a role inprey capture. In this study, we investigated the role of red leaf coloration (an indicator of anthocyanins)on prey capture using Pinguicula planifolia (Chapman’s Butterwort). Overall,red leaves had less prey (i.e., Collembola) than green leaves, suggesting that red colorationdoes not enhance prey capture for Chapman’s Butterwort. However, the frequent presenceof Collembola on leaves suggests that this plant species could be relying on other cues toattract prey (e.g., olfactory cues).

Succession, Scott J. Meiners, Steward Pickett
Succession, Scott J. Meiners, Steward Pickett
Faculty Research & Creative Activity
Succession in a strict sense refers to the recovery and revegetation of an area following a disturbance such as the cessation of agriculture, the retreat of a glacier, or an intense forest fi re. Succession is a special case of vegetation dynamics, although many early ecologists referred to all vegetation change as succession. Succession includes a series of compositional and structural changes, often in a directional manner. The common occurrence of natural disturbances coupled with the extent of human activity on the planet makes succession one of the most ubiquitous ecological processes. Because invasion is a crucial feature of succession, …

Domain And Propositions Of Succession Theory, Steward Pickett, Scott J. Meiners, Mary L. Cadenasso
Faculty Research & Creative Activity
Succession is perhaps the oldest of ecological concepts, having arisen when ecology was emerging as a self-conscious discipline (Mcintosh 1985). Yet it continues to address many fundamental issues in ecology, to support important applications, and to synthesize the insights and perspectives of other theories. Thus, it fulfills two functions key in assessing the utility of a contemporary ecological theory. First, it exhibits the attributes of a mature, welldeveloped, and intensively tested theory (Glenn-Lewin et al. 1992; Pickett and Cadenasso 2005). Second, it provides a linkage among theories and applications that have usually been considered separately (Walker et al. 2007). For …

Faculty Research & Creative Activity
ABSTRACT.—Macrofungi from two old-growth prairie grove remnants in the Midwestern United States (Brownfield and Trelease Woods. Champaign Co., IL ) were surveyed over two summer and fall fruiting periods. Communities of Ascomycetes, Basidiomycetes and Myxomycètes were sampled and compared using multivariate statistical analyses. Standard estimations of species richness were calculated for comparison with other studies of fungal diversity. Environmental factors (rainfall, humidity, air temperature and soil temperature at 10 cm depth) as well as leaf litter composition, and woody plant communities were surveyed to assess their impact on fungal communities. Fungal community structure was found to differ significandy both between …

Allelopathic Effects Of Goldenrod Species On Turnover In Successional Communities, Nikki Pisula, Scott Meiners
Allelopathic Effects Of Goldenrod Species On Turnover In Successional Communities, Nikki Pisula, Scott Meiners
Faculty Research & Creative Activity
While goldenrod species are often found to be allelopathic in laboratory settings, its importance in controlling plant community dynamics has been much more difficult to assess. We designed a study to determine whether allelopathy is related to the success of goldenrods in abandoned agricultural land. To accomplish this, we conducted laboratory bioassays for six co-occurring goldenrod species and compared these results to the cover and impacts of these species in the field. We determined the germination responses of two target species to a gradient of leaf extract concentrations to assess the allelopathic potential of these goldenrods. We also used long-term …
Liana Host Preference And Implications For Deciduous Forest Regeneration, Laura Ladwig, Scott Meiners
Liana Host Preference And Implications For Deciduous Forest Regeneration, Laura Ladwig, Scott Meiners
Faculty Research & Creative Activity
Lianas have the potential to shape forest communities and alter forest regeneration. However, impacts of lianas on forest regeneration, particularly in temperate forests, are largely unstudied. To understand potential liana impacts on the community we need to first know the location and intensity of liana burdens on host trees. We examined liana-tree host references within a series of young regenerating deciduous forests in the Piedmont region of New Jersey, USA. Established trees ($ 5 cm dbh) and the lianas associated with each tree were surveyed in 2008. The five most abundant liana species were Celastrus orbiculatus, Lonicera japonica, Parthenocissus quinquefolia, …
Relative Allelopathic Potential Of Invasive Plant Species In A Young Disturbed Woodland, Nikki Pisula, Scott Meiners
Relative Allelopathic Potential Of Invasive Plant Species In A Young Disturbed Woodland, Nikki Pisula, Scott Meiners
Faculty Research & Creative Activity
Invasive plant species are often more successful within introduced areas when compared to their natural ranges. Allelopathy has been suggested as a potential mechanism for this success because invasive plants frequently establish monocultures and may produce allelochemicals evolutionarily novel to the recipient community. However, species are typically tested in isolation making the relative strength of allelopathy difficult to assess. We conducted laboratory bioassays for 10 co-occurring non-native species to determine the relative strength of their allelopathic potential. These species represented a suite of successful invaders within a young forest and were from a variety of plant life forms: trees, lianas, …
Spatiotemporal Dynamics Of Lianas During 50 Years Of Succession To Temperate Forest, Laura Ladwig, Scott Meiners
Spatiotemporal Dynamics Of Lianas During 50 Years Of Succession To Temperate Forest, Laura Ladwig, Scott Meiners
Faculty Research & Creative Activity
Although they are important components of forest communities, the general ecology and spatiotemporal patterns of temperate lianas during forest regeneration are largely unknown. The dependence of lianas on other plants for physical support makes them a potentially important driver of community dynamics. We examined 50 years of vegetation data from an old-field succession study to determine the dynamics and community controls on liana expansion within the Piedmont region of New Jersey, USA. Four lianas, Lonicera japonica, Parthenocissus quinquefolia, Toxicodendron radicans, and Vitis spp., occurred in enough abundance for detailed analyses. In general, liana cover peaked during mid-succession (20–30 years post-abandonment) …

Eastern Illinois University was established in 1899, and from its beginning recognized the importance of the botanical sciences. Two terms of botany were required for the four year program. Otis W. Caldwell, a botanist, was one of the original faculty members. He taught all of the biology courses and initiated the acquisition of a greenhouse. Caldwell was the first of a series of talented and dedicated botany professors including Edgar N. Transeau, Ernest L. Stover, Hiram F. Thut and John E. Ebinger. These and many other professors incorporated a field component into almost all classes. This dedication to the study …
Native And Exotic Plant Species Exhibit Similar Population Dynamics During Succession, Scott J. Meiners
Native And Exotic Plant Species Exhibit Similar Population Dynamics During Succession, Scott J. Meiners
Faculty Research & Creative Activity
A growing body of literature has led to the debate in invasion biology whether exotic species perform within communities differently than native taxa due to inherent advantages. To address this issue, the population dynamics of native and exotic plant species were assessed from a 48-year record of permanent plot data from the Hutcheson Memorial Forest Center (New Jersey, USA) to determine rate of increase, lag time, maximum frequency, and the year of peak frequency. Overall, native and exotic species exhibited very similar population dynamics. Rates of increase and length of lag times were similar between native and exotic taxa but …

Additions To The Flora Of Connecticut, Gordon C. Tucker
Faculty Research & Creative Activity
Since the publication of the Connecticut checklist by Dowhan (1979), new state records have continued to appear. These were summarized by Mehrhoff (1995), including some made by Tucker ( 1987, 1991 ). Although geographically distant, the flora of Connecticut has continued to hold my attention since the publication of a flora of the southeastern part of the state (Tucker 1995). Over the past decade, I have made several collections that are new records for the state flora. These new records are reported in this paper, as well as a 1970 collection of Coronilla scorpio ides that was never added to …

Fungal Spore Dispersal By The Eastern Box Turtle (Terrapene Carolina Carolina), S. Jones, W. Jordan, Scott Meiners, A. Miller, A. Methven
Faculty Research & Creative Activity
Although spores from most macrofungi are wind- or water-dispersed, dispersal may also occur via biotic vectors. The Eastern box turtle (Terrapene carolina carolina) is a facultative mycovore that may play an important role in fungal spore dispersal although, to date, no information exists on fungi occurring in fecal samples of box turtles or on the ecological significance of box turtles as spore dispersal vectors. Consequently, a study of the potential for Eastern box turtles to act as vectors for spore dispersal was initiated by capturing wild turtles and collecting fecal samples. Serial dilutions from fecal samples were made to enumerate …

Seed And Seedling Ecology Of Acer Saccharum And Acer Platanoides: A Contrast Between Native And Exotic Congeners, Scott J. Meiners
Seed And Seedling Ecology Of Acer Saccharum And Acer Platanoides: A Contrast Between Native And Exotic Congeners, Scott J. Meiners
Faculty Research & Creative Activity
The exotic tree, Acer platanoides, is increasing in forests of northeastern North America, largely within the range of its native congener, Acer saccharum. A combination of field and controlled experiments was used on seeds and seedlings of these congeners to determine species characteristics that may be contributing to these floristic changes. Acer platanoides experienced lower rates of seed predation than A. saccharum in field experiments. Differences in the dispersal and allocation characteristics of the two species were small and not likely to explain the relative success of A. platanoides. Greenhouse- grown seedlings of A. platanoides were much larger than those …

The Relationship Between Community Diversity And Exotic Plants: Cause Or Consequence Of Invasion?, Scott J. Meiners, Mary L. Cadenasso
Faculty Research & Creative Activity
Invasion ecology has suffered from the artificial separation of invasibility and impact processes in understanding the ationship between diversity and plant invasion. By studying these independently functioning stages of invasion in concert, we can gain great insight into the biological causes and consequences of invasions, and develop crucial information for the generation of adequate management strategies. Our conceptual framework provides a structure to synthesize the current body of research, suggests research needed to fill the gaps in understanding and to organize results from future research. The framework is a powerful tool to guide ecological understanding of the relationship between invasion …

Faculty Research & Creative Activity
Forest edges are known to affect plant community composition and habitat use by animals. However, the direct influence of edges in determining patterns of tree regeneration is poorly understood. Survival of and herbivore damage to Quercus ruln-a seedlings were experimentally determined for seedlings planted across a forest--old-field edge gradient. Seedling survival was lowest inside the forest ( 1%), intermediate at the edge (25%) and highest within the old-field portion of the gradient (49%). Deer herbivory decreased with increasing distance into the old field. Seedling survival increased under Rosa multiflora and decreased in plots with mammalian herbivory. Seedling height was significantly …
