Most insect communities are composed of evolutionarily diverse lineages, but detailed phylogenetic analyses of whole communities are lacking, in particular in species-rich tropical faunas.

Morphological evolution and modularity of the caecilian skull
Background Caecilians (Gymnophiona) are the least speciose extant lissamphibian order, yet living forms capture approximately 250 million years of evolution since their earliest divergences.

Toward a metabolic theory of life history
Significance Data and theory reveal how organisms allocate metabolic energy to components of the life history that determine fitness. In each generation, animals take up biomass energy from the environment and expend it on survival, growth, and ...

History of life on Earth [PDF]
All of you will be familiar with those educational graphics that put into stark perspective how tiny is our place in the Universe, how on a clock that began ticking with the origin of life, humans evolved less than a minute before midnight. And the time since Current Biology began, 25 years ago, would be the merest fraction of a second.

We present a novel perspective on life‐history evolution that combines recent theoretical advances in fluctuating density‐dependent selection with the notion of pace‐of‐life syndromes (POLSs) in behavioural ecology.

Background Tapeworms are agents of neglected tropical diseases responsible for significant health problems and economic loss. They also exhibit adaptations to a parasitic lifestyle that confound comparisons of their development with other animals ...

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

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

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