Leptodactylus fuscus

open access: yes, 1992
Leptodactylus fuscus (Schnhder, 1799) Citada como L. sibilatrix (Wied, 1824) por Gallardo (1964a: 45) en base a un ejemplar (MACN 2012) proveniente de “ Uruguay, costa del río Uruguay ”. Langguth (1976:30) la citó como L. sibilator, acotando: "Existe un sólo registro de esta especie. Su presencia en Uruguay debe ser confirmada”. Heyer (1978: 50) colocó

Guild‐Specific Frog Responses to Natural Habitat Structure Gradients in an Atlantic Forest Mosaic

open access: yesEcological Research, Volume 41, Issue 5, September 2026.
This study investigated how habitat structure gradients are associated with frog species richness and occupancy in a naturally heterogeneous Atlantic Forest mosaic. We found that frog richness and occupancy patterns varied among ecological guilds and were highest in sites associated with lower values of the habitat structure gradient, which also ...

OCCURRENCE OF NATIVE AND INTRODUCED CRAYFISH IN NORTHEASTERN GERMANY AND NORTHWESTERN POLAND.

open access: yesKnowledge and Management of Aquatic Ecosystems, 2001
On the basis of monitoring undertaken in 300 lakes since 1994, the recent stocking situation for freshwater crayfish in northeastern Germany (Uckermark) and northwestern Poland (Szczecin area) is described. The two native species Astacus astacus (L.) and

The annual cycle of spermatozoa content in the vas deferens and some reproductive parameters in the narrow-clawed crayfish Pontastacus leptodactylus (Eschscholtz, 1823)

open access: yesAquaculture Reports, 2019
Understanding the annual dynamic of gametes in crayfish is useful for successful management of crayfish population. The annual variations in spermatozoa content of vas deferens, gonado-somatic index (GSI), hepatosomatic index (HSI), vas deferens index ...

The consumption of the White-lipped Frog (Leptodactylus macrosternum Leptodactylidae: Anura) in the state of Rondônia in the Brazilian Amazon

open access: yesBiotemas, 2021
The consumption of anurans by subsistence hunters in the Brazilian Amazon is unrecorded. Given this scenario, the objective of this study is to present the first record of White-lipped Frog consumption by subsistence hunters in the Amazon region of ...

Antipredatory Strategies of Anurans: An Updated Conceptual Review

open access: yesEthology, Volume 132, Issue 9, Page 662-708, September 2026.
To unravel the evolutionary dynamics of predator–prey interactions, we propose an updated, three‐tiered classification of anuran antipredatory strategies. By mapping non‐behavioral, individual, and group defenses across five functional phases, this integrative framework introduces the concept of synergetic coupling.

Astacus leptodactylus

open access: yes, 2020
Narrow-clawed crayfish Astacus leptodactylus (Eschscholtz, 1823) The distribution of narrow-clawed crayfish is mainly linked with the south-eastern region of the country and more rarely in the rest of Latvia (Bērziņš 1936, Mazītis 1955, 1967, 1971). Earlier evaluations of the distribution of this species have been quite inconsistent.

A Generalizable Tool for Predicting Developmental Phenology for Wild Ecotherms

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Custom hatch timing models developed for four North American Lithobates frog species. Models are parameterized from Moore (1939). Panels (A, B) shows differential developmental rates under varying thermal regimes and G × E interactions. ABSTRACT Development in poikilothermic organisms is strongly temperature‐dependent, particularly during early life ...
