Tame affairs: domesticated transposase and domestic pigs [PDF]
EMBO reports, 2010 Long thought to be genomic junk, domesticated transposons have turned out to be an incredible source of new genes. Two studies—one this issue of EMBO reports—show that a domesticated hAT transposase is a transcriptional repressor of IGF2 that regulates muscle growth and has over 1,200 additional putative targets in the mammalian genome.

Long‐term trends in parasite diversity and infection levels: approaches and patterns
Biological Reviews, EarlyView.ABSTRACT Parasites exist in every ecosystem, affecting nearly all organisms and playing a complex role in human societies. On the one hand, they contribute substantially to biodiversity and support ecosystem stability by performing essential ecological functions.

The impacts of biological invasions
Biological Reviews, EarlyView.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

Animals domestication and agriculture as outcomes of collusion [PDF]
Although it is known that there are circumstances where the competitive situation does not promote social welfare maximization, collusion is usually associated with firms’ strategies that decrease welfare.

Biological Reviews, EarlyView.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 ...

Biological Reviews, EarlyView.ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

A neuro‐behavioural model of neophobia
Biological Reviews, EarlyView.ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome
Biological Reviews, EarlyView.ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...
