Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological 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 ...

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Modification of Insect and Arachnid Behaviours by Vertically Transmitted Endosymbionts: Infections as Drivers of Behavioural Change and Evolutionary Novelty

open access: yesInsects, 2012
Vertically acquired, endosymbiotic bacteria such as those belonging to the Rickettsiales and the Mollicutes are known to influence the biology of their arthropod hosts in order to favour their own transmission.

A spinose appendage fragment of a problematic arthropod from the Early Ordovician of Morocco [PDF]

open access: yes, 2006
A highly spinose fragment of a possibly raptorial appendage from the Arenig (Early Ordovician) of the Upper Fezouata Formation north of Zagora, southeastern Morocco is described as the arthropod Pseudoangustidontus duplospineus gen. et sp. nov.

Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

open access: yesBiological 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 ...

How Changes in Plant Community Structure Affect Terrestrial Invertebrate Food Webs [PDF]

open access: yes, 2015
We investigated how change in plant community composition and vegetative structure brought about by annual grass-specific herbicide application affects terrestrial arthropod communities, with special emphasis on the potential mutualists and predators of ...

Scalable Greedy Algorithms for Transfer Learning

open access: yes, 2016
In this paper we consider the binary transfer learning problem, focusing on how to select and combine sources from a large pool to yield a good performance on a target task.

A neuro‐behavioural model of neophobia

open access: yesBiological 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.

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...
