Data from: The nutritional ecology of maturation in a carnivorous insect

Ekhlas Al Shareefi & Sheena C. Cotter
Herbivores and omnivores, faced with a nutritionally complex diet, have evolved the capacity to balance the intake of specific nutrients. Recent studies have found that carnivores also have this capacity, despite their more nutritionally homogeneous diet. However, unlike herbivores and omnivores who prioritise protein intake when restricted to imbalanced foods, carnivores instead show much stricter regulation of fat intake. These choices to over- or under-consume nutrients when the intake target cannot be achieved are known...

Data from: Shorebirds as important vectors for plant dispersal in Europe

Ádám Lovas-Kiss, Marta I. Sanchez, David M. Wilkinson, Neil E. Coughlan, Jose A. Alves & Andy J. Green
Shorebirds (Charadriiformes) undergo rapid migrations with potential for long-distance dispersal (LDD) of plants. We studied the frequency of endozoochory by shorebirds in different parts of Europe covering a broad latitudinal range and different seasons. We assessed whether plants dispersed conformed to morphological dispersal syndromes. A total of 409 excreta samples (271 faeces and 138 pellets) were collected from redshank (Tringa totanus), black-winged stilt (Himantopus himantopus), pied avocet (Recurvirostra avosetta), northern lapwing (Vanellus vanellus), Eurasian curlew...

Data from: Behavioural thermoregulation via microhabitat selection of winter sleeping areas in an endangered primate: Implications for habitat conservation

Liz A.D. Campbell, Patrick J. Tkaczynski, Mohamed Mouna, Abderrahim Derrou, Lahcen Oukannou, Bonaventura Majolo, Els Van Lavieren & Liz A. D. Campbell
Strategic microhabitat selection allows animals in seasonally cold environments to reduce homeostatic energy costs, particularly overnight when thermoregulatory demands are greatest. Suitable sleeping areas may therefore represent important resources for winter survival. Knowledge of microhabitat use and potential impacts of anthropogenic habitat modification can aid species conservation through development of targeted habitat management plans. Wild, endangered Barbary macaques (Macaca sylvanus) in logged cedar-oak forest were studied to investigate 1) the hypothesis that macaques select winter...

Data from: Pelvis morphology suggests that early Mesozoic birds were too heavy to contact incubate their eggs

D. Charles Deeming & Gerald Mayr
Numerous new fossils have driven an interest in reproduction of early birds but direct evidence remains elusive. No Mesozoic avian eggs can be unambiguously assigned to a species, which hampers our understanding of the evolution of contact incubation, which is a defining feature of extant birds. Compared to living species eggs of Mesozoic birds are relatively small, but whether the eggs of Mesozoic birds could actually have borne the weight of a breeding adult has...

Data from: Unpredictable movement as an anti-predator strategy

Graham Richardson, Patrick Dickinson, Oliver H.P. Burman, Thomas W. Pike & Oliver H. P. Burman
Prey animals have evolved a wide variety of behaviours to combat the threat of predation, and these have been generally well studied. However, one of the most common and taxonomically widespread antipredator behaviours of all has, remarkably, received almost no experimental attention: so-called ‘protean’ behaviour. This is behaviour which is sufficiently unpredictable to prevent a predator anticipating in detail the future position or actions of its prey. In this study, we used human ‘predators’ participating...

Data from: Age and quality-dependent DNA methylation correlate with melanin-based colouration in a wild bird

Carl D. Soulsbury, Anssi Lipponen, Kristie Wood, Charles A. Mein, Joe I. Hoffman, Christophe Lebigre & Joseph I. Hoffman
Secondary sexual trait expression can be influenced by fixed individual factors (such as genetic quality) but also by dynamic factors (such as age and environmentally induced gene expression) that may be associated with variation in condition or quality. In particular, melanin-based traits are known to relate to condition and there is a well-characterized genetic pathway underpinning their expression. However, the mechanisms linking variable trait expression to genetic quality remain unclear. One plausible mechanism is that...

Data from: Age, condition and dominance-related sexual ornament size before and during the breeding season in the black grouse Lyrurus tetrix

Sarah Harris, Matti Kervinen, Christophe Lebigre, Thomas W. Pike & Carl D. Soulsbury
Male ornaments function as honest cues of male quality in many species and are subject to intra- and intersexual selection. These ornaments are generally studied during peak expression, however their size outside the breeding season may determine ultimate ornament size and costliness, and as such reproductive success. We investigated whether male black grouse Lyrurus tetrix eye comb size was related to age, condition and measures of male dominance before and during the breeding season. Total...

Data from: Extreme and rapid bursts of functional adaptations shape bite force in amniotes

Manabu Sakamoto, Marcello Ruta & Chris Venditti
Adaptation is the fundamental driver of functional and biomechanical evolution. Accordingly, the states of biomechanical traits (absolute or relative trait values) have long been used as proxies of adaptations in response to direct selection. However, ignoring evolutionary history, in particular ancestry, passage of time and the rate of evolution, can be misleading. Here, we apply a recently developed phylogenetic statistical approach using significant rate shifts to detect instances of exceptional rates of adaptive changes in...
