Bird community data from Wallacea biogeographic region collected 2018-2020

S.L. Mitchell, D.P. Edwards, R.W. Martin, A. Kastanya, A. Karja, P.G. Akbar, K. Jordan, T. Martin, J. Supriatna, N. Winarni, Z.G. Davies & M.J. Struebig
Bird community data from fixed point count stations generated by experienced ornithologists in Borneo and the Wallacean islands of Sulawesi (Buton), Seram, Buru, Talaud and Sangihe. Bird surveys were undertaken between 2016 and 2020, with work on any given island lasting ~3 months, except for Borneo where surveys were undertaken across 3 years (2014 – 2016). Surveys were repeated four times at each site on Sulawesi (Buton), Seram, Buru and once each on Talaud and...

A patch-dynamic metacommunity perspective on the persistence of mutualistic and antagonistic bipartite networks

Jinbao Liao, Daniel Bearup & Giovanni Strona
The structure of interactions between species within a community plays a key role in maintaining biodiversity. Previous studies have found that the effects of these structures might substantially differ depending on interaction type, for example, a highly connected and nested architecture stabilizes mutualistic communities, while the stability of antagonistic communities is enhanced in modular and weakly connected structures. Here we show that, when network dynamics are modelled using a patch-dynamic metacommunity framework, the qualitative differences...

Microclimate-driven trends in spring-emergence phenology in a temperate reptile (Vipera berus): Evidence for a potential 'climate trap'?

Rebecca Turner & Ilya Maclean
Climate change will increase the exposure of organisms to higher temperatures, but can also drive phenological shifts that alter their susceptibility to conditions at the onset of breeding cycles. Organisms rely on climatic cues to time annual life-cycle events, but the extent to which climate change has altered cue reliability remains unclear. Here, we examine the risk of a ‘climate trap’ – a climatically-driven desynchronisation of the cues that determine life-cycle events and fitness later...

Edge effects and vertical stratification of aerial insectivorous bats across the interface of primary-secondary Amazonian rainforest

Natalie Yoh, James Clarke, Adrià López-Baucells, Maria Mas, Paulo E.D. Bobrowiec, Ricardo Rocha & Christoph F.J. Meyer
Edge effects - abiotic and biotic changes associated with habitat boundaries - are key drivers of community change in fragmented landscapes. Their influence is heavily modulated by matrix composition. With over half of the world’s tropical forests predicted to become forest edge by the end of the century, it is paramount that conservationists gain a better understanding of how tropical biota is impacted by edge gradients. Bats comprise a large fraction of tropical mammalian fauna...

Transformed crane data from: Balancing structural complexity with ecological insight in spatio-temporal species distribution models

Megan Laxton, Óscar Rodríguez De Rivera, Andrea Soriano-Redondo & Janine Illian
The potential for statistical complexity in species distribution models (SDMs) has greatly increased with advances in computational power. Structurally complex models provide the flexibility to analyse intricate ecological systems and realistically messy data, but can be difficult to interpret, reducing their practical impact. Founding model complexity in ecological theory can improve insight gained from SDMs. Here, we evaluate a marked point process approach, which uses multiple Gaussian random fields to represent population dynamics of the...

The minimum land area requiring conservation attention to safeguard biodiversity

James Allan, Hugh Possingham, Scott Atkinson, Anthony Waldron, Moreno Di Marco, Stuart Butchart, Vanessa Adams, Daniel Kissling, Thomas Worsdell, Chris Sandbrook, Gwili Gibbon, Kundan Kumar, Piyush Mehta, Martine Maron, Brooke Williams, Kendall Jones, Brendan Wintle, April Reside & James Watson
Ambitious conservation efforts are needed to stop the global biodiversity crisis. Here, we estimate the minimum land area to secure important biodiversity areas, ecologically intact areas, and optimal locations for representation of species ranges and ecoregions. We discover that at least 64 million km2 (44% of terrestrial area) would require conservation attention (ranging from protected areas to land-use policies) to meet this goal. Over 1.8 billion people live on these lands, so responses that promote...
