Fins are relevant non-lethal surrogates for muscle to measure stable isotopes in amphibians

Knowledge and Management of Aquatic Ecosystems, 2019
Stable isotope analyses (SIA) are now widely used in ecology research to quantify the trophic implications of a large range of ecological processes.

Shifts in type 2 vomeronasal receptor expression during postnatal development in the lungfish olfactory organ

Journal of Anatomy, EarlyView.
Lungfish possess a lamellar OE and a primitive VNO called as a recess epithelium (RecE). Among the lungfish V2Rs expressed in both the lamellar OE and the RecE in small individuals, some became restricted to the RecE in large individuals. These results suggest functional separation between the lamellar OE and the RecE is still incomplete in juveniles ...

Feeding habits of the endangered Japanese diving beetle Hydaticus bowringii (Coleoptera: Dytiscidae) larvae in paddy fields and implications for its conservation

European Journal of Entomology, 2020
The diving beetle Hydaticus bowringii Clark, 1864 (Coleoptera: Dytiscidae) is on the Red List of Japan as 'Near Threatened'. However, there is no quantitative information on the feeding habits of its larvae, which could be used to aid its conservation ...

Beaver dam analogues increase amphibian breeding occupancy and bat activity

Restoration Ecology, EarlyView.
Abstract Introduction Beavers are ecosystem engineers that can create ponds, increase stream complexity, and enhance biodiversity. To mimic these and other effects, restoration practitioners increasingly install beaver dam analogues (BDAs) in degraded streams.

The Tadpoles of Hyla rufitela (Anura: Hylidae)

Revista de Biología Tropical, 2005
The validity of the published description of Hyla rufitela is questioned because the origin of the described tadpoles does not correspond to the distribution of this species.

Vulnerability and behavioral responses of South Chinese anuran tadpoles to native dragonfly (Pantala flavescens) naiads and introduced western mosquitofish (Gambusia affinis)

Journal of Freshwater Ecology, 2017
Anti-predator behavior is an important fitness component in most animals. Alien predator species are a serious threat to amphibian populations. We studied the vulnerability and behavioral defenses of tadpoles of six Chinese anurans in response to the ...

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Alterações histopatológicas em girinos de rã-touro alimentados com rações comerciais de diferentes níveis protéicos Histopathological alterations in bullfrog tadpoles fed commercial diets with three levels of crude protein

Revista Brasileira de Zootecnia, 2008
Realizaram-se necropsia e exame histopatológico de girinos de rã-touro (Rana catesbeiana) alimentados com rações comerciais formuladas com 32, 36, 45 ou 55% de proteína bruta (PB) visando estabelecer a relação entre o nível de proteína bruta da ração e a

Survey of mercury in boreal chorus frog (Pseudacris maculata) and wood frog (Rana sylvatica) tadpoles from wetland ponds in the Prairie Pothole Region of Canada

FACETS, 2017
Tadpoles are important prey items for many aquatic organisms and often represent the largest vertebrate biomass in many fishless wetland ecosystems. Neurotoxic mercury (Hg) can, at elevated levels, decrease growth, lower survival, and cause developmental

Numbers, neighbors, and hungry predators: What makes chemically defended aposematic prey susceptible to predation?

Ecology and Evolution, 2020
Many chemically defended aposematic species are characterized by relatively low toxin levels, which enables predators to include them in their diets under certain circumstances.
