“…Anthropogenic habitat modification is, and will continue to be, one of the most significant drivers of biodiversity declines (Barlow et al, 2016; Matuoka et al, 2020; Pereira et al, 2010). Of the various anthropogenic stressors, urbanization is one of the most widespread near‐term threats to biodiversity assemblages (McDonald et al, 2019).…”

Urban expansion poses a serious threat to biodiversity. Given that the expected area of urban land cover is predicted to increase by 2–3 million km2 by 2050, urban environments are one of the most widespread human‐dominated land‐uses affecting biodiversity. Responses to urbanization differ greatly among species. Some species are unable to tolerate urban environments (i.e., urban avoiders), others are able to adapt and use areas with moderate levels of urbanization (i.e., urban adapters), and yet others are able to colonize and even thrive in urban environments (i.e., urban exploiters). Quantifying species‐specific responses to urbanization remains an important goal, but our current understanding of urban tolerance is heavily biased toward traditionally well‐studied taxa (e.g., mammals and birds). We integrated a continuous measure of urbanization—night‐time lights—with over 900,000 species' observations from the Global Biodiversity Information Facility to derive a comprehensive analysis of species‐specific (N = 158 species) responses of butterflies to urbanization across Europe. The majority of butterfly species included in our analysis avoided urban areas, regardless of whether species' urban affinities were quantified as a mean score of urban affinity across all occurrences (79%) or as a species' response curve to the whole urbanization gradient (55%). We then used species‐specific responses to urbanization to assess which life history strategies promote urban affinity in butterflies. These trait‐based analyses found strong evidence that the average number of flight months, likely associated with thermal niche breath, and number of adult food types were positively associated with urban affinity, while hostplant specialism was negatively associated with urban affinity. Overall, our results demonstrate that specialist butterflies, both in terms of thermal and diet preferences, are most at risk from increasing urbanization, and should thus be considered in urban planning and prioritized for conservation.

“…Passive acoustic monitoring and long-term studies remain promising approaches for capturing relative abundance data to estimate population dynamics with respect to global change (Pérez-Granados et al, 2019;Pérez-Granados & Schuchmann, 2020;Sugai et al, 2020). Trait databases are gaining momentum as sources of functional diversity to test hypotheses under the Hutchinsonian niche concept (Gallagher et al, 2020;Leclerc et al, 2020;Matuoka et al, 2020). In particular, exploring how functional roles of species change across abiotic gradients can dramatically improve our understanding of abiotic tolerances to more accurately predict range dynamics.…”

Global change creates an urgent need to predict spatial responses of biota to support the conservation of sufficient habitat to maintain biodiversity. We present species distribution model theory and a synthesis of avian literature on approaches to collecting occurrence data, selecting explanatory variables and analytical processes currently in use to predict future distributions. We find that interpreting the validity of current predictive distributions is hindered by variation in spatio-temporal resolution of data sets that force hypothesis testing under the Grinnellian niche concept. Broadly, the capacity of species to shift their geographic ranges under land use and climate change is expected to be limited by both large scale (i.e., the physiological or fundamental niche) and small scale (i.e., the realized or tolerance niche) factors. We highlight the strengths and weaknesses of widely used explanatory variables and analytical approaches tailored to macrohabitat characteristics and the Grinnellian niche concept. This synthesis addresses if and how current approaches align with theory and makes recommendations for future directions to improve the accuracy of predictive distribution modelling.

“…Most agricultural expansion in the tropics happens at the expense of forests and leads to an increase in forest fragmentation (Hansen et al 2020). This expansion affects all aspects of biodiversity: research has documented losses in species richness (Scales and Marsden 2008), shifts in species composition (Newbold et al 2016), reductions of functional diversity (Matuoka et al 2020), and erosion of phylogenetic diversity (Li et al 2020). Importantly, the response of biodiversity to land-use change differs among species groups (Newbold et al 2014) and world regions (Williams and Newbold 2020), but certain groups and regions are understudied compared to others.…”

Large expanses of tropical rainforest have been converted into agricultural landscapes cultivated by smallholder farmers. This is also the case in north-eastern Madagascar; a region that retains a significant proportions of forest cover despite shifting hill rice cultivation and vanilla agroforestry. The region is also a global hotspot for herpetofauna diversity, but how this diversity is affected by land-use change remains largely unknown. Using a space-for-time study design to uncover land-use effects, we compared species diversity and community composition in seven prevalent land uses: unburned (old-growth forest, forest fragment, and forest-derived vanilla agroforest) and burned (fallow-derived vanilla agroforest, woody fallow, herbaceous fallow) land-use types, and rice paddy. We conducted six comprehensives, time-standardized searches across at least ten replicates of each land-use type and applied genetic barcoding to confirm species identification. We documented an outstanding diversity of endemic herpetofauna (119 species): amphibian species richness at the plot level was highest in old-growth forest and significantly lower in all other land-use types. Plot-level reptile species richness was significantly higher in the unburned land-use types than burned land-use types. For both amphibians and reptiles, the less-disturbed land-use types showed more uneven communities and particularly in old-growth forest, the species composition differed significantly from all other land-use types. Amphibians showed a higher level of forest dependency compared to reptiles (38% versus 28% of species exclusively occurred in old-growth forest). Our analyses thus revealed that the two groups respond differently to land-use change: we found less pronounced losses of reptile species richness especially in unburned agricultural habitats, suggesting that reptiles are less susceptible to land-use change than amphibians. Overall, old-growth forest harboured a unique diversity, but some species also thrived in agroforestry systems, especially if these were forest-derived. This highlights the importance of conserving old-growth forests and non-burned land-use types within the agricultural landscape.
