Functional diversity and trait filtering of insectivorous bats on forest islands created by an Amazonian mega dam

Guthieri T. Colombo, Raffaello Di Ponzio, Maíra Benchimol, Carlos A. Peres & Paulo Estefano D. Bobrowiec
1. Mega dams in lowland tropical forests often create large archipelagos, leading to biodiversity decay and disruption of ecosystem functioning in remnant habitat islands. 2. We investigated the functional diversity and functional trait filtering of aerial insectivorous bats in both insular forest patches created by a vast ~30-yr-old hydropower reservoir and the adjacent mainland continuous forest in Central Amazonia. 3. Bats were surveyed using passive bat recorders across 34 forest sites. Based on a set...

Effects of pair migratory behaviour on breeding phenology and success in a partially migratory shorebird population

Verónica Méndez, Jose Alves, Jennifer Gill, Böðvar Þórisson, Camilio Carneiro, Aldís Pálsdóttir, Sölvi Vignisson & Tomas Gunnarsson
In migratory systems, variation in individual phenology can arise through differences in individual migratory behaviours, and this may be particularly apparent in partial migrant systems, where migrant and resident individuals are present within the same population. Links between breeding phenology and migratory behaviour or success are generally investigated at the individual level. However, for breeding phenology in particular, the migratory behaviours of each member of the pair may need to be considered simultaneously, as breeding...

Vanuatu Water Quality Dataset - CTD Profiles - 2016-2018

CTD depth profiles from a dataset supporting a baseline assessment of marine water quality around Vanuatu, South Pacific. As part of the Commonwealth Marine Economies Programme, water quality measurements were collected over three years in the coastal waters around the island of Efate, and on one occasion around the island of Tanna. Observations focus on Port Vila (Efate), which is the main urbanised area on the Island. Parameters included are: salinity, temperature, turbidity, light attenuation,...

Genomic changes underlying repeated niche shifts in an adaptive radiation

David A. Marques, Felicity C. Jones, Federica Di Palma, David M. Kingsley & Thomas E. Reimchen
In adaptive radiations, single lineages rapidly diversify by adapting to many new niches. Little is known yet about the genomic mechanisms involved, i.e. the source of genetic variation or genomic architecture facilitating or constraining adaptive radiation. Here, we investigate genomic changes associated with repeated invasion of many different freshwater niches by threespine stickleback in the Haida Gwaii archipelago, Canada, by re-sequencing single genomes from one marine and 28 freshwater populations. We find 89 likely targets...

Raw data for: Plastic responses of males and females interact to determine mating behaviour

Tracey Chapman
Individuals can respond plastically to variation in their social environment. However, each sex may respond to different cues and contrasting aspects of competition. Theory suggests that the plastic phenotype expressed by one sex can influence evolutionary dynamics in the other, and that plasticity simultaneously expressed by both sexes can exert sex-specific effects on fitness. However, data are needed to test this theory base. Here, we examined whether the simultaneous expression of adaptive plasticity by both...

Extracting abundance information from DNA-based data

Mingjie Luo, Yinqiu Ji, David Warton & Douglas Yu
The accurate extraction of species-abundance information from DNA-based data (metabarcoding, metagenomics) could contribute usefully to the reconstruction of diets and quantitative foodwebs, the inference of species interactions, the modelling of population dynamics and species distributions, the biomonitoring of environmental state and change, and the inference of false positives and negatives. However, capture bias, capture noise, species pipeline biases, and pipeline noise all combine to inject error into DNA-based datasets. This review focuses on methods for...

Individual repeatability of avian migration phenology: a systematic review and meta-analysis

Kirsty Franklin, Malcolm Nicoll, Simon Butler, Ken Norris, Norman Ratcliffe, Shinichi Nakagawa & Jennifer Gill
Changes in phenology and distribution are being widely reported for many migratory species in response to shifting environmental conditions. Understanding these changes and the situations in which they occur can be aided by understanding consistent individual differences in phenology and distribution and the situations in which consistency varies in strength or detectability. Studies tracking the same individuals over consecutive years are increasingly reporting migratory timings to be a repeatable trait, suggesting that flexible individual responses...

Cross-scale drivers of woody plant species commonness and rarity in the Brazilian drylands

Bruno X. Pinho, Diego Trindade, Carlos Peres, Davi Jamelli, Renato A. F. De Lima, Elâine M.S. Ribeiro, Inara R. Leal & Marcelo Tabarelli
Aim: Locally abundant species are typically widespread, while locally scarce species are geographically restricted – the so-called abundance-occupancy relationships (AORs). AORs help explain the drivers of species rarity and community assembly, but little is known about how variation around such relationships is driven by species traits and niche-based processes, particularly in tropical woody plants. We tested the hypothesis that AORs in tropical dryland woody plants are positive and mediated by niche and functional traits along...

Seychelles warblers with silver spoons: juvenile body mass is a lifelong predictor of annual survival, but not annual reproduction or senescence

Thomas Brown, Hannah Dugdale, Martijn Hammers, Jan Komdeur & David Richardson
The environment experienced during development, and its impact on intrinsic condition, can have lasting outcomes for individual phenotypes and could contribute to variation in adult senescence trajectories. However, the nature of this relationship in wild populations remains uncertain, owing to the difficulties in summarizing natal condition and in long-term monitoring of individuals from free-roaming long-lived species. Utilizing a closely monitored, closed population of Seychelles warblers (Acrocephalus sechellensis), we determine whether juvenile body mass is associated...

Jethro George Gauld, João P. Silva, Philip W. Atkinson, Paul Record, Marta Acácio, Volen Arkumarev, Julio Blas, Willem Bouten, Niall Burton, Inês Catry, Jocelyn Champagnon, Elizabeth A. Masden, Gary D. Clewley, Mindaugas Dagys, Olivier Duriez, Klaus‐Michael Exo, Wolfgang Fiedler, Andrea Flack, Guilad Friedemann, Johannes Fritz, Clara García-Ripollés, Stefan Garthe, Dimitri Giunchi, Atanas Grozdanov, Roi Harel … & Victoria Saravia
1. Wind turbines and power lines can cause bird mortality due to collision or electrocution. The biodiversity impacts of energy infrastructure (EI) can be minimised through effective landscape-scale planning and mitigation. The identification of high-vulnerability areas is urgently needed to assess potential cumulative impacts of EI while supporting the transition to zero-carbon energy. 2. We collected GPS location data from 1,454 birds from 27 species susceptible to collision within Europe and North Africa and identified...

Subarctic afforestation: effects of forest plantations on ground-nesting birds in lowland Iceland

Aldís E. Pálsdóttir, Jennifer Gill, Jose Alves, Snaebjörn Palsson, Verónica Méndez, Harry Ewing & Tómas Gunnarsson
Planting forests is a commonly suggested measure to mitigate climate change. The resulting changes in habitat structure can greatly influence the diversity and abundance of pre-existing wildlife. Understanding these consequences is key for avoiding unintended impacts of afforestation on habitats and populations of conservation concern. Afforestation in lowland Iceland has been gaining momentum in recent years and further increases are planned. Iceland supports internationally important breeding populations of several ground-nesting, migratory bird species that mostly...

Sousa, Juliana Schietti, Luiz De Souza Coelho, José Ferreira Ramos, Diogenes De Andrade Lima Filho, Iêda Leão Amaral, Francisca Dionízia De Almeida Matos, Lorena M. Rincón, Juan David Cardenas Revilla, Marcelo Petratti Pansonato, Rogerio Gribel, Edelcilio Marques Barbosa, Ires Paula De Andrade Miranda, Luiz Carlos De Matos Bonates, Juan Ernesto Guevara, Rafael P. Salomão, Leandro Valle Ferreira, Dário Dantas Do Amaral, Nigel C.A. Pitman, Corine Vriesendorp, Tim R. Baker, Roel Brienen, Marcelo De Jesus Veiga Carim … & Flávia R.C. Costa
Tree diversity and composition in Amazonia are known to be strongly determined by the water supplied by precipitation. Nevertheless, within the same climatic regime, water availability is modulated by local topography and soil characteristics (hereafter referred to as local hydrological conditions), varying from saturated and poorly drained to well-drained and potentially dry areas. While these conditions may be expected to influence species distribution, the impacts of local hydrological conditions on tree diversity and composition remain...

Supplementary data, code, and information for ‘Global surface temperature over the past two millennia’

M. Mann & P. Jones
We present reconstructions of Northern and Southern Hemisphere mean surface temperature over the past two millennia based on high-resolution ‘proxy’ temperature data which retain millennial-scale variability. These reconstructions indicate that late 20th century warmth is unprecedented for at least roughly the past two millennia for the Northern Hemisphere. Conclusions for the Southern Hemisphere and global mean temperature are limited by the sparseness of available proxy data in the Southern Hemisphere at present.

Supplementary data, code, and information for ‘Climate over Past Millennia’

P. Jones & M. Mann
We review evidence for climate change over the past several millennia from instrumental and high-resolution climate ‘‘proxy’’ data sources and climate modeling studies. We focus on changes over the past 1 to 2 millennia. We assess reconstructions and modeling studies analyzing a number of different climate fields, including atmospheric circulation diagnostics, precipitation, and drought. We devote particular attention to proxy-based reconstructions of temperature patterns in past centuries, which place recent large-scale warming in an appropriate...

Genomic associations with poxvirus across divergent island populations in Berthelot’s pipit

Eleanor C. Sheppard, Claudia A. Martin, Claire Armstrong, Catalina González-Quevedo, Juan Carlos Illera, Alexander Suh, Lewis G. Spurgin & David S. Richardson
Understanding the mechanisms and genes that enable animal populations to adapt to pathogens is important from an evolutionary, health and conservation perspective. Berthelot’s pipit (Anthus berthelotii) experiences extensive and consistent spatial heterogeneity in avian pox infection pressure across its range of island populations, thus providing an excellent system with which to examine how pathogen-mediated selection drives spatial variation in immunogenetic diversity. Here we test for evidence of genetic variation associated with avian pox at both...

Frequency-dependent viscosity of salmon ovarian fluid has biophysical implications for sperm-egg interactions

Marco Graziano
Gamete-level sexual selection of externally fertilising species is usually achieved by modifying sperm behaviour with mechanisms thought to alter the chemical environment in which gametes perform. In fish this can be accomplished through the ovarian fluid, a substance released with the eggs at spawning. While its biochemical effects in relation to sperm energetics have been investigated, the influence of the physical environment in which sperm compete remains poorly explored. Our objective was therefore to gain...
