Exploring Antipredator Mechanisms: New Findings in Ceratophryid Tadpoles
(Society for the Study of Amphibians and Reptiles, 2016-06)
Previous studies found that two larvae of the family Ceratophryidae, Ceratophrys ornata (Ornate Horned Frogs) and Ceratophrys cranwelli (Cranwell's Horned Frogs), are able to produce underwater sounds as an antipredator ...
Large and in charge: cortisol levels vary with sex, diet, and body mass in an Antarctic predator, the leopard seal
(2023)
Evaluating physiological responses in the context of a species’ life history, demographics, and ecology is essential to understanding the health of individuals and populations. Here, we measured the main mammalian ...

Underwater sound emission as part of an antipredator mechanism in Ceratophrys cranwelli tadpoles
(Wiley Blackwell Publishing, Inc, 2014-07)
We report the emission of underwater sounds in the tadpoles of a second member of the family Ceratophryidae, Ceratophrys cranwelli. These tadpoles produce a short metallic-like sound, which consists of short trains of ...
Seed size variation in the palm Euterpe edulis and the effects of seed predators on germination and seedling survival
(Elsevier B.V., 2006-05-01)
Intraspecific variation in seed size is common in wild plant populations and has important consequences for the reproductive success of individual plants. Multiple, often conflicting evolutionary forces mediated by biotic ...
Caudal fin-nipping by Serrasalmus maculatus (Characiformes: Serrasalmidae) in a small water reservoir: seasonal variation and prey selection
(Soc Brasileira Zoologia, Univ Federal Parana, 2015-12-01)
We evaluated how seasonality affects the frequency and intensity of fin-nipping, as well as the fish prey preferences of Serrasalmus maculatus Kner, 1858. The study took place in a small reservoir of the Ribeirao Claro ...
Intraguild Competition of Three Noctuid Maize Pests
(Oxford Univ Press Inc, 2016-08-01)
The western bean cutworm Striacosta albicosta (Smith), the fall armyworm Spodoptera frugiperda (J. E. Smith), and the corn earworm Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) are among the major lepidopteran pests ...
