Density-dependent effect on reproductive behaviour of Lysmata amboinensis and L. boggessi (Decapoda: Caridea: Hippolytidae) [PDF]
, 2007 We compared the reproductive behaviours of two protandric simultaneous hermaphroditic species (Lysmata amboinensis and L. boggessi) that belong to two groups of Lysmata shrimp with different morphology, geographical distribution, and density.

Drivers of intrapopulation variation in resource use in a generalist predator, the macaroni penguin [PDF]
Intrapopulation variation in resource use occurs in many populations of generalist predators with important community and evolutionary implications. One of the hypothesised mechanisms for such widespread variation is ecological opportunity, i.e. resource

A typology of schools across the four nations of the United Kingdom: Class, race and geography
British Educational Research Journal, EarlyView.Abstract In this paper we analyse the hierarchical field of schools across the United Kingdom during the transition to university and suggest that there are five socially distinct clusters of schools. Our five‐cluster typology of UK schools is composed of an established group of elite private and state schools, schools for the white rural and suburban ...

Dynamics of multiple sexual signals in relation to climatic conditions [PDF]
, 2007 Question: Can trait-specific phenotypic plasticity in response to annual environmental variation lead to changes in the strength of sexual selection through the relative expression of sexual ornaments at the population level?

Convolved Substructure: Analytically Decorrelating Jet Substructure Observables
, 2018 A number of recent applications of jet substructure, in particular searches for light new particles, require substructure observables that are decorrelated with the jet mass.

Extraordinary morphological changes in valve morphology during the ontogeny of several species of the Australian ostracod genus Bennelongia (Crustacea, Ostracoda) [PDF]
, 2013 Ostracods belonging to the genus Bennelongia differ much in valve morphology between adults and juveniles. Adult valves are asymmetrical, characterised by a beak-like feature in the anteroventral region of the left valve, and, with some notable ...

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 ...

moult : An R Package to Analyze Moult in Birds
Journal of Statistical Software, 2013 Moult is the process by which birds replace their feathers. It is a costly process in terms of energy and reduced flight ability but necessary for the maintenance of the plumage and its functions. Because birds generally avoid to moult while engaged with

Journal of Avian BiologyWhile there is ample evidence supporting genetic control of migratory behaviour in short‐lived passerines, long‐lived social species have been assumed to rely solely on cultural inheritance of migratory routes.
