Supernumerary teeth observed in a live True’s beaked whale in the Bay of Biscay [PDF]

open access: yesPeerJ, 2019
Mesoplodont beaked whales are one of the most enigmatic mammalian genera. We document a pod of four beaked whales in the Bay of Biscay breaching and tail slapping alongside a large passenger ferry.

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.

Metabolic rate evolves rapidly and in parallel with the pace of life history

open access: yesNature Communications, 2018
Metabolic rates and life history strategies are both thought to set the “pace of life”, but whether they evolve in tandem is not well understood. Here, using a common garden experiment that compares replicate paired populations, we show that Trinidadian ...

Hyperthermophiles in the history of life [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2006
Today, hyperthermophilic (‘superheat-loving’) bacteria and archaea are found within high-temperature environments, representing the upper temperature border of life. They grow optimally above 80°C and exhibit an upper temperature border of growth up to 113°C.

To remain or leave: Dispersal variation and its genetic consequences in benthic freshwater invertebrates

open access: yesEcology and Evolution, 2019
Variation in dispersal capacity may influence population genetic variation and relatedness of freshwater animals thus demonstrating how life‐history traits influence patterns and processes that in turn influence biodiversity. The majority of studies have

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 ...

Life History Strategies

open access: yes, 2016
Life history theory posits organisms face tradeoffs in how they allocate resources to reproduction, parenting, and growth. These patterns of resource allocation can be classified more broadly into life history strategies, which vary on a continuum from fast to slow.

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.

Genetic and life-history traits associated with the distribution of prophages in bacteria

open access: yesThe ISME Journal, 2016
Nearly half of the sequenced bacteria are lysogens and many of their prophages encode adaptive traits. Yet, the variables driving prophage distribution remain undetermined.

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.
