Micronuclei induction in Rana catesbeiana tadpoles by the pyrethroid insecticide lambda-cyhalothrin
Genetics and Molecular Biology, 2003 Pyrethroid lambda-cyhalothrin genotoxicity was evaluated using the micronucleus test in Rana catesbeiana tadpoles. The effects of concentration and exposure time on the micronuclei frequency were studied in blood smears obtained from tadpoles exposed to ...

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.

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.

Moduli Stabilization from Fluxes in a Simple IIB Orientifold [PDF]
, 2002 We study novel type IIB compactifications on the T^6/Z_2 orientifold. This geometry arises in the T-dual description of Type I theory on T^6, and one normally introduces 16 space-filling D3-branes to cancel the RR tadpoles.

The spread of non‐native species
Biological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Radio fiber bursts and fast magnetoacoustic wave trains
, 2012 We present a model for dm-fiber bursts that is based on assuming fast sausage magnetoacoustic wave trains that propagate along a dense vertical filament or current sheet.

Anomalies, RG-flows and Open/Closed String Duality [PDF]
, 2001 We discuss the interplay between IR and UV divergences in vacuum configurations with open and unoriented strings. We establish a general one-to-one correspondence between anomalies and R-R tadpoles associated to sectors with non-trivial Witten index. The

The impacts of biological invasions
Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
