ON THE LIFE-HISTORY OF ASCARIS LUMBRICOIDES [PDF]
BMJ, 1916 I. In the following three experiments it will be shown that ripe eggs of Ascaris suilla can hatch in the intestine of the pig, that the larvae issuing from these eggs enter the body of the pig and pursue the same course through the body as in the rat and mouse.

From Cosmos to Intelligent Life: The Four Ages of Astrobiology [PDF]
, 2012 The history of life on Earth and in other potential life-bearing planetary platforms is deeply linked to the history of the universe. Since life as we know it relies on chemical elements forged in dying heavy stars, the universe needs to be old enough for stars to form and evolve. Current cosmological theory indicates that the universe is 13.7$\pm 0.13$

Size, microhabitat, and loss of larval feeding drive cranial diversification in frogs
Nature Communications, 2021 The evolution of metamorphic species may be constrained by different ecologies of the larval and adult stages. Here, Bardua et al. show that in frogs, adult ecology is more important than larval ecology for skull evolution, but species that don’t feed as

Current Biology, 2014 In his book on behavioural endocrinology, Randy Nelson describes 'stress' as a 'notoriously ethereal concept'. Yet, despite this lack of clarity, studies of the consequences of stress across different time scales, life history stages, taxa and levels of biological enquiry form a large part of modern biology and biomedicine.

Benthic megafauna of the western Clarion-Clipperton Zone, Pacific Ocean [PDF]
ZooKeys, 2022 There is a growing interest in the exploitation of deep-sea mineral deposits, particularly on the abyssal seafloor of the central Pacific Clarion-Clipperton Zone (CCZ), which is rich in polymetallic nodules.

Using natural history collections to investigate changes in pangolin (Pholidota: Manidae) geographic ranges through time [PDF]
PeerJ, 2021 Pangolins, often considered the world’s most trafficked wild mammals, have continued to experience rapid declines across Asia and Africa. All eight species are classed as either Vulnerable, Endangered or Critically Endangered by the International Union ...

Do human ‘life history strategies’ exist?
Evolution and human behavior, 2020 Interest in incorporating life history research from evolutionary biology into the human sciences has grown rapidly in recent years. Two core features of this research have the potential to prove valuable in strengthening theoretical frameworks in the ...

Macroparasite Life Histories [PDF]
Current Biology, 2011 Parasites and parasitism is common. Worm macroparasites have evolved life-history traits that allow them to successfully transmit between spatially and temporally separated patches of host resource and to survive within these environments. Macroparasites have common life-history strategies to achieve this, but these general themes are modified in a ...
