Abstract:
... Herbivore‐induced plant defences regulated by the phytohormones jasmonic acid (JA) and salicylic acid (SA) are predicted to influence herbivore population dynamics, in part because they can operate in a density‐dependent manner. While there is ample evidence that herbivore‐induced plant responses affect individual performance and growth of herbivores, whether they scale‐up to regulate herbivore po ...

Abstract:
... Studies on the highly pathogenic avian influenza (HPAI) H5N1 suggest that wild bird migration may facilitate its long‐distance spread, yet the role of wild bird community composition in its transmission risk remains poorly understood. Furthermore, most studies on the diversity–disease relationship focused on host species diversity without considering hosts’ phylogenetic relationships, which may le ...

Abstract:
... Helminth parasites can have wide‐ranging, detrimental effects on host reproduction and survival. These effects are best documented in humans and domestic animals, while only a few studies in wild mammals have identified both the forces that drive helminth infection risk and their costs to individual fitness. Working in a well‐studied population of wild baboons (Papio cynocephalus) in the Amboseli ...

Abstract:
... Bats are reservoirs for emerging human pathogens, including Hendra and Nipah henipaviruses and Ebola and Marburg filoviruses. These viruses demonstrate predictable patterns in seasonality and age structure across multiple systems; previous work suggests that they may circulate in Madagascar's endemic fruit bats, which are widely consumed as human food. We aimed to (a) document the extent of henipa ...

Abstract:
... Plants exhibit impressive genetic and chemical diversity, not just between species but also within species, and the importance of plant intraspecific variation for structuring ecological communities is well known. When there is variation at the local population level, this can create a spatially heterogeneous habitat for specialised herbivores potentially leading to non‐random distribution of indi ...

Abstract:
... Ungulates migrate to maximize nutritional intake when forage varies seasonally. Populations of ungulates often include both migratory and non‐migratory individuals, but the mechanisms driving individual differences in migratory behaviour are not well‐understood. We quantified associations between hypothesized drivers of partial migration and the likelihood of migration for individual ungulates tha ...

Abstract:
... Understanding factors that facilitate interspecific pathogen transmission is a central issue for conservation, agriculture, and human health. Past work showed that host phylogenetic relatedness and geographical proximity can increase cross‐species transmission, but further work is needed to examine the importance of host traits, and species interactions such as predation, in determining the degree ...

Abstract:
... Ecological theory on the trophic impacts of invasive fauna on native competitors is equivocal. Whilst increased interspecific competition can result in coexisting species having constricted and diverged trophic niches, the competing species might instead increase their niche sizes to maintain energy intakes. Empirical experiments can test invasion theory on competitive interactions and niche sizes ...

Abstract:
... Intraspecific variation in floral visitor behaviour and pollination efficiency has been much less studied than interspecific variation. Nevertheless, it is clear that large differences in these traits exist within species, and in particular between sexes within species. With the exception of a few well‐studied interactions, however, the consequences of these differences in the pollinators and visi ...

Abstract:
... Under life‐history theories of ageing, increased senescence should follow relatively high reproductive effort. This expectation has rarely been tested against senescence varying between and within the two sexes, although such an approach may clarify the origins of sex‐specific ageing in the context of a given mating system. Nazca boobies (Sula granti; a seabird) practise serial monogamy and bipare ...

Abstract:
... The recovery of piscivorous birds around the world is touted as one of the great conservation successes of the 21st century, but for some species, this success was short‐lived. Bald eagles, ospreys and great blue herons began repatriating Voyageurs National Park, USA, in the mid‐20th century. However, after 1990, only eagles continued their recovery, while osprey and heron recovery failed for unkn ...
