Combining social information use and comfort-seeking for nest site selection in a cavity-nesting raptor
Published: 2020-09-30
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Ornithology
When selecting a breeding site, individuals can use social information to reduce the uncertainty regarding habitat quality. In particular, individuals from several bird species tend to reuse nests previously occupied by competitors. Re-occupying nests previously used by conspecifics or heterospecifics could result from exploiting social information by copying competitors’ choice (the ‘social [...]

The rapid, global spread and human health impacts of SARS-CoV-2, the agent of COVID-19 disease, demonstrates humanity’s vulnerability to zoonotic disease pandemics. Although anthropogenic land use change is known to be the major driver of zoonotic pathogen spillover from wildlife to human populations, the scientific underpinnings of land use-induced zoonotic spillover have rarely been [...]
Sexual dichromatism, size dimorphism and microscale anatomy of white wing stripe in blue tit (Cyanistes caeruleus)
Published: 2020-09-25
Subjects: Biology, Life Sciences
Achromatic patches are a common element of plumage patterns in many bird species and there is growing body of evidence that in many avian taxa they can play a signaling role in mate choice. Although the blue tit is a well-established model species in the studies on colouration, its white wing patch has never been examined in the context of sex-specific trait expression. In this exploratory study, [...]

Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Population Biology, Terrestrial and Aquatic Ecology
1. Cushion plants can have positive impacts on plant richness in severe environments and possibly across trophic levels on arthropods, an under-studied topic. 2. This study examined whether soil communities under cushions of Silene acaulis and Diapensia lapponica have higher richness and abundance of soil microarthropods (Acari, Collembola) than adjacent non-cushion vegetation; and whether [...]
GoogleTrends reflects the abundance of the Asian tiger mosquito (Aedes albopictus): a call for the web-based surveillance of invasive alien vector species
Published: 2020-09-23
Subjects: Entomology, Environmental Studies, Life Sciences, Social and Behavioral Sciences
The Asian tiger mosquito (Aedes albopictus) is becoming widespread in Europe, where it can transmit some major arboviruses, including Chikungunya and Dengue. While surveillance initiatives are being implemented and harmonized between states, the spread of A.albopictus is outrunning them and cost-effective surveillance tools are needed. In this study, we tested whether on-line searches on Google [...]

Biodiversity is a cornerstone of human health and well-being. However, while evidence of the contributions of nature to human health is rapidly building, research into how biodiversity relates to human health remains limited in important respects. In particular, a better mechanistic understanding of the range of pathways through which biodiversity can influence human health is needed. These [...]
Rumicastrum Ulbrich (Montiaceae): a beautiful name for the Australian calandrinias
Published: 2020-09-19
Subjects: Biodiversity, Life Sciences
For more than 30 years, Montiaceae specialists have agreed that Australian species classified in Calandrinia Kunth pertain to a distinct and divergent lineage whose oldest validly published name is Rumicastrum Ulbrich. In 1998, more than half of accepted species were transferred erroneously to a new genus, Parakeelya Hershk. However, taxonomists and databases have continued to classify the [...]

Meta-analysis reveals an extreme “decline effect” in the impacts of ocean acidification on fish behaviour
Published: 2020-09-14
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Ocean acidification – decreasing oceanic pH resulting from the uptake of excess atmospheric CO2 – has the potential to affect marine life in the future. Among the possible consequences, a series of studies on coral reef fishes suggested that the direct effects of acidification on fish behaviour may be extreme and have broad ecological ramifications. Recent studies documenting a lack of effect of [...]
