Patterns of second‐to‐fourth digit length ratios (2D:4D) in two species of frogs and two species of lizards at La Selva, Costa Rica 

DiRenzo, Graziella Vittoria; Stynoski, Jennifer Lynn (2012)
It is now well documented that androgen and estrogen signaling dur- ing early development cause a sexual dimorphism in second-to-fourth digit length ratio (2D:4D). It is also well documented that males of mam- malian ...

The management of Typha domingensis (Typhaceae) affects macroinvertebrate assemblages in the Palo Verde Wetland, Guanacaste, Costa Rica 

Trama, Florencia A.; Rizo Patron Viale, Federico L. S.; Kumar, Anjali S.; Stynoski, Jennifer Lynn; McCoy Colton, Michael B.; Springer Springer, Monika (2017)
The Palo Verde wetland, one of the most important places for aquatic organisms in Costa Rica, is currently recovering from an invasive expansion of Typha domingensis (cattail). A monitoring program was designed to understand ...

Discrimination of offspring by indirect recognition in an egg-feeding dendrobatid frog, Oophaga pumilio 

Stynoski, Jennifer Lynn (2009)
Offspring discrimination, the differential treatment of offspring and unrelated young, functions in numerous animal taxa to ensure that vital and costly parental care behaviours are appropriately directed. Discrimination ...

Ground Anoles (Anolis humilis) Discriminate between Aposematic and Cryptic Model Insects 

Baruch, Ethan M.; Manger, Morgan A.; Stynoski, Jennifer Lynn (2016)
Aposematic coloration allows predators to use visual cues to avoid eating potentially toxic or distasteful prey. Predators across many animal taxa actively avoid aposematically colored prey and remember distasteful brightly ...

Prolonged development of the middle ear in Rhinella horribilis 

Womack, Molly C.; Stynoski, Jennifer Lynn; Voyles, Meredith K.; Coloma Román, Luis A.; Hoke, Kim L. (2018)
Despite the benefit of the tympanic middle ear to airborne hearing sensitivity, anurans range in how soon they develop functional middle ears after transitioning to life on land. Previous evi- dence suggested that bufonids ...

Differences in escape behavior between a cryptic and an aposematic litter frog 

Ozel, L. Deniz; Stynoski, Jennifer Lynn (2011)
Clay models have been used to investigate the relative antipredator effectiveness of cryptic and of aposematic coloration in litter frogs, but such studies do not account for possible differences in prey escape behavior. ...

Cannibalism by large tadpoles of Rhinophrynus dorsalis (Anura: Rhinophrynidae) 

Stynoski, Jennifer Lynn; Sasa Marín, Mahmood (2018)
In June 2014, we captured approximately 100 R. dorsalis tadpoles in a net from a seasonal wetland in Palo Verde National Park (10.3428 N, 85.3375 W) in N, 85.3375 W) in northwestern Costa Rica. While rearing the tadpoles ...

Larval aggression is independent of food limitation in nurseries of a poison frog 

Dugas, Matthew B.; Stynoski, Jennifer Lynn; Strickler, Stephanie (2016)
Aggression between nurserymates is common in animals and often hypothesized to result from proximate resource limita- tion. In numerous terrestrial frogs, larvae develop in phytotelmata, tiny water bodies where resources ...

Rhinella yunga. Predation 

Tortorelli, Claire M.; Gannon, Dustin G.; Stynoski, Jennifer Lynn; Trama, Florencia A. (2016)
Rhinella yunga, a recently described toad species of the Rhinella margaritifera group (Moravec et al. 2014. Zookeys 37:35–56), is known from the tropical mountains of the Cordillera Yanachaga, Junin Province, Peru. Rhinella ...

Empirical evidence for multiple costs of begging in poison frog tadpoles 

Stynoski, Jennifer Lynn; Stynoski, Peter B.; Noble, Virginia R. (2018)
In recent decades, theoretical and empirical work has investigated the relative roles of costs and benefits in inhibiting excessive displays of begging to parents. Whether costs are important in maintaining reliability of ...
