Toward accurate species‐level metabarcoding of arthropod communities from the tropical forest canopy

open access: yesEcology and Evolution, 2019
Metabarcoding of arthropod communities can be used for assessing species diversity in tropical forests but the methodology requires validation for accurate and repeatable species occurrences in complex mixtures.

Development of a recombinase polymerase amplification (RPA) fluorescence assay for the detection of Schistosoma haematobium

open access: yesParasites & Vectors, 2019
Background Accurate diagnosis of urogenital schistosomiasis is vital for surveillance and control programmes. While a number of diagnostic techniques are available there is a need for simple, rapid and highly sensitive point-of-need (PON) tests in areas ...

Mitochondrial Molecular Adaptations and Life History Strategies Coevolve in Plants [PDF]

open access: yes, 2008
Messenger RNA secondary structure prevents mutations at functionally important sites. Mutations at exposed sites would cause micro-adaptations, niche-specialization, and therefore, can be thought to promote K-strategists. Exposing, rather than protecting,

Annual changes in the Biodiversity Intactness Index in tropical and subtropical forest biomes, 2001–2012

open access: yesScientific Reports, 2021
Few biodiversity indicators are available that reflect the state of broad-sense biodiversity—rather than of particular taxa—at fine spatial and temporal resolution.

A Comparative demography of plants based upon elasticities of vital rates [PDF]

open access: yes, 2004
Elasticities of matrix elements from population projection matrices are commonly used to analyze the relative contributions of different life history transitions (birth, survival, growth) to the finite rate of increase (lambda).

Convergent evolution in toothed whale cochleae

open access: yesBMC Evolutionary Biology, 2019
Background Odontocetes (toothed whales) are the most species-rich marine mammal lineage. The catalyst for their evolutionary success is echolocation - a form of biological sonar that uses high-frequency sound, produced in the forehead and ultimately ...

Holcophora Staudinger, 1871, a senior synonym of Aponoea Walsingham, 1905, syn. n., (Lepidoptera, Gelechioidea, Gelechiidae): with Holcophora inderskella (Caradja, 1920), comb. n., transferred from Blastobasis Zeller, 1855 (Blastobasidae) [PDF]

open access: yesNota Lepidopterologica, 2019
Blastobasis inderskella Caradja, 1920, is transferred from Blastobasidae to Gelechiidae and placed in the Palaearctic genus Holcophora Staudinger, 1871. The genus Aponoea Walsingham, 1905, syn.

Synthetic and Semi-Synthetic Microplastic Ingestion by Mesopelagic Fishes From Tristan da Cunha and St Helena, South Atlantic

open access: yesFrontiers in Marine Science, 2021
Mesopelagic fishes were sampled around Tristan da Cunha and St Helena in the South Atlantic from the RRS Discovery at depths down to 1000 m. Sampling was part of the Blue Belt Programme, a marine survey of British Overseas Territories funded by the ...

Environmental conditions during early life accelerate the rate of senescence in a short-lived passerine bird [PDF]

open access: yes, 2015
Environmental conditions experienced in early life may shape subsequent phenotypic traits including life history. We investigated how predation risk caused by domestic cats (Felis silvestris catus) and local breeding density affected patterns of ...

Development of novel multiplex microsatellite polymerase chain reactions to enable high-throughput population genetic studies of Schistosoma haematobium

open access: yesParasites & Vectors, 2015
Background Human urogenital schistosomiasis caused by Schistosoma haematobium is widely distributed across Africa and is increasingly targeted for control and regional elimination.
