Diversity of the strongly rheophilous tadpoles of Malagasy tree frogs, genus Boophis (Anura, Mantellidae), and identification of new candidate species via larval DNA sequence and morphology

ZooKeys, 2012
This study provides detailed morphological descriptions of previously unknown tadpoles of the treefrog genus Boophis Tschudi and analyses of habitat preferences of several of these tadpoles in Ranomafana National Park.

Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Evaluating a structured expert elicitation approach for adaptive conservation management based on lessons from five years in practice

Conservation Biology, EarlyView.
Abstract Adaptive management of threatened species relies on having ex ante estimates of species’ responses to different interventions. Structured expert elicitation is often used to generate these estimates, but comparisons of these expert‐predicted outcomes with observed results are rare.

Tadpoles of Three Species of the Rhinella granulosa Group with a Reinterpretation of Larval Characters

, 2020
The Rhinella granulosa group currently comprises 14 species of Neotropical toadswhose monophyly is strongly supported by several synapomorphies, including adistinctive set of larval characters.

Cyanosis by methemoglobinemia in tadpoles of Cochranella granulosa (Anura: Centrolenidae)

Revista de Biología Tropical, 2010
Tadpoles inhabit generally well oxygenated rivers and streams, nevertheless they were found in areas with limited oxygen availability inside the rivers.

Environmental DNA succeeds in detecting a low‐density population of endangered harlequin frogs

Conservation Science and Practice, EarlyView.
This work evaluates the use of environmental DNA (eDNA) to detect the Critically Endangered Jambato Harlequin Frog (Atelopus ignescens)—an iconic species once thought extinct and now known only from a single locality in the Ecuadorian Andes. Our study demonstrates the effectiveness of eDNA in detecting the Jambato in a low‐density amphibian population,

High chytrid prevalence and infection intensities in tadpoles of Mixophyes fleayi

Context The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) has caused catastrophic biodiversity loss globally, but species and life stages within species respond differently to the pathogen.

tadpoles

, 2002
1. Conditions experienced during the early stages of development may have carry-over effects on performance during later life. The egg laying period and embryonic development of temperate and boreal zone amphibians often coincides with peak acidity ...

Prolactin and Tadpole Growth.

Experimental Biology and Medicine, 1967
SummaryMammalian prolactin inhibits thyroxin-induced resorption of the tail in Rana catesbeiana tadpoles. Mammalian growth hormone does not show this effect. The possible importance of prolactin as a larval growth hormone in amphibians is emphasized.

Characterization of dermatan sulfate and chondroitin sulfate profiles during brain regeneration in Styela plicata

The FEBS Journal, EarlyView.
Adult ascidians are capable of regenerating their entire brains following injury, and glycosaminoglycans have been shown to either promote or inhibit neuritogenesis. In this study, dermatan 2,6‐disulfate (D2,6S) was identified as the predominant complex carbohydrate in the ascidian brain.
