Social Learning Through Associative Processes: A Computational Theory, Johan Lind, Stefano Ghirlanda, Magnus Enquist

Publications and Research

Social transmission of information is a key phenomenon in the evolution of behaviour and in the establishment of traditions and culture. The diversity of social learning phenomena has engendered a diverse terminology and numerous ideas about underlying learning mechanisms, at the same time that some researchers have called for a unitary analysis of social learning in terms of associative processes. Leveraging previous attempts and a recent computational formulation of associative learning, we analyse the following learning scenarios in some generality: learning responses to social stimuli, including learning to imitate; learning responses to non-social stimuli; learning sequences of actions; learning to …

Dung Beetle Functional Traits Related To Restoration Management Practices In Tallgrass Prairie, Sheryl C. Hosler

Graduate Research Theses & Dissertations

The restoration of degraded ecosystems often focuses on reestablishing species richness and diversity of native organisms, especially plants. However, functional trait descriptions of communities are emerging as a more comprehensive approach to evaluating restorations, including consumer communities. I examined the species composition and functional traits of dung beetle (Coleoptera: Scarabeidae) communities across a chronosequence of restored tallgrass prairie in Illinois, in which sites varied in the presence of bison and the application of prescribed fire during the study. Data were collected on behavioral guild and body measurements, and functional diversity metrics (functional richness, evenness, divergence, and dispersion) were analyzed using …

A Rapid And Accurate Minion-Based Workflow For Tracking Species Biodiversity In The Field, Hendrik Freitag, Simone Maestri, Emanuela Cosentino, Marta Paterno, Jhoana M. Garces, Luca Marcolungo, Massimiliano Alfano, Iva Njunjić, Menno Schilthuizen, Ferry Slik, Michele Menegon, Marzia Rossato, Massimo Delledonne

Biology Faculty Publications

Genetic markers (DNA barcodes) are often used to support and confirm species identification. Barcode sequences can be generated in the field using portable systems based on the Oxford Nanopore Technologies (ONT) MinION sequencer. However, to achieve a broader application, current proof-of-principle workflows for on-site barcoding analysis must be standardized to ensure a reliable and robust performance under suboptimal field conditions without increasing costs. Here, we demonstrate the implementation of a new on-site workflow for DNA extraction, PCR-based barcoding, and the generation of consensus sequences. The portable laboratory features inexpensive instruments that can be carried as hand luggage and uses standard …

Trade-Offs Shape Carotenoid-Based Color Variation In Redheaded Pine Sawfly (Neodiprion Lecontei) Larvae, Maranda Gaines

Lewis Honors College Capstone Collection

Carotenoids serve various ecological roles in animals including coloration, immune responses, and vision. Carotenoid-derived coloration is greatly emphasized in the literature, particularly relating to mate choice and aposematic warning. However, the trade-offs between the color and non-color functions of carotenoids are not thoroughly explored. In the redheaded pine sawfly (Neodiprion lecontei), some larval populations have yellow pigmentation, using carotenoids derived from their diets for aposematic warning coloration. Other larval populations are white in color, having genetically lost the ability to produce the yellow pigment. Because carotenoids are essential to life functions in both the yellow and white populations, we aim …

New Tribes, Overview And Checklist Of Neotropical Cladonotinae (Orthoptera: Caelifera: Tetrigidae), Daniela Santos Martins Silva, Oscar J. Cadena-Castañeda, Marcelo Ribeiro Pereira, Fernando Campos De Domenico, Carlos Frankl Sperber

Insecta Mundi

The Cladonotinae (Orthoptera: Caelifera: Tetrigidae) are a peculiar tetrigid taxon characterized by a relatively widened fascial carina on the frontal costa. This group currently has a doubtful taxonomic status since this is the only character shared by its members. Here, we provide an overview of the Cladonotinae reported from the Neotropical region (29 species, three of them fossils), based on the morphological examination of the specimens housed at several museums. We show that Neotropical Cladonotinae share more characteristics, which strengthen its taxonomic status, and propose two new tribes: Choriphyllini n. trib. and Mucrotettigini n. trib. We propose the new combination …

Fall Field Report, August - November 2019, W. Ross Silcock

Nebraska Bird Review

By far the most striking feature of this fall’s report is the large number of lingering migrants, a trend that is continuing and apparently increasing, especially among passerines. Editor Jan Paseka counted 17 uses of the word “tardy” and 43 of “late” or “latest”. It is tempting to relate this to the warmer environment and resulting increased availability of food items at higher latitudes and later dates than in previous years. A sad note: a startling occurrence in Gering, Scotts Bluff 20 Aug was described by Marie Smith: “We had a huge hailstorm around 10:30. The hail was probably pea …

Quantifying Signpost Usage By Captive Male White-Tailed Deer, Cassie L. Auxt, Eric S. Michel, Jonathan A. Jenks

The Prairie Naturalist

White-tailed deer (Odocoileus virginianus) use rubbing of signpost structures to communicate during the breeding season. Rubbing of signpost structures allows deer to communicate via visual and chemical cues, which allows them to establish dominance hierarchies and maintain hierarchal status throughout the breeding season (Moore and Marchinton 1974, Miller et al. 1981, Hewitt 2011). Once a living tree is rubbed, the exposed light-colored sapwood creates a stark contrast in wooded areas, increasing visibility and further enticing deer to investigate the structure (Oehler et al. 1995). Anatomically, the tubular apocrine sudoriferous glands of white-tailed deer are located at the antler …
