Inter‐municipal cooperation and local government perspectives on community health and wellbeing

Michelle J. Morgan, Elaine Stratford, Siobhan Harpur, Samantha Rowbotham, more

Australian Journal of Public Administration > 83 > 3 > 394 - 414

Globally, local governments face increasing service delivery demands and citizen expectations, including in relation to community health and wellbeing. Inter‐municipal cooperation is one strategy to respond to those demands. In Australia, however, there is limited empirical research about the types of inter‐municipal cooperation local governments engage in and about their perspectives on community...

Testing the links between bird diversity, alien species and disturbance within a human‐modified landscape

Fabio Marcolin, Pedro Segurado, Dan Chamberlain, Luís Reino

Ecography > 2024 > 1 > n/a - n/a

Introduced alien species are associated with lower taxonomic, functional and phylogenetic diversity of native communities and negative impacts on ecosystem functioning. This is particularly evident in habitats where human disturbance may favour alien species, posing an additional stressor on native communities. Following the community resistance hypothesis (higher diversity promotes higher resistance...

The influence of household structure and composition on the introduction of solid, semisolid and soft foods among children aged 6–8 months: An analysis based on Ethiopia Demographic and Health Surveys

Asnake Ararsa Irenso, Miaobing Zheng, Karen J. Campbell, Dan Chamberlain, more

Maternal & Child Nutrition > 19 > 1 > n/a - n/a

The early and late introduction of complementary food, both prevalent in Ethiopia, are associated with morbidities, growth faltering and developmental risks in children. The interhousehold network around the primary caregiver's intrahousehold network is critical in influencing the age of introducing complementary foods. This study examined the influence of household composition and structures on complementary...

High nest failure but better nestling quality for early breeders in an alpine population of Northern Wheatear (Oenanthe oenanthe)

Martha Maria Sander, Susanne Jähnig, Simeon Lisovski, Camille Mermillon, more

Ibis > 165 > 1 > 125 - 141

Climate change is leading to the advancement of spring conditions, resulting in an earlier snowmelt and green‐up, with highest rates of change in highly seasonal environments, including alpine habitats. Migratory birds breeding at high elevations need to time their arrival and lay dates accurately with this advancement, but also with the annually variable spring conditions at their breeding sites,...

Evidence for intraspecific phenotypic variation in songbirds along elevation gradients in central Europe

Martha Maria Sander, Dan Chamberlain

Ibis > 162 > 4 > 1355 - 1362

Studying phenotypic variations along gradients may provide insights into mechanisms that drive species distributions and thus can be useful indicators of environmental change. In mountains, the study of phenotypic variation along elevation gradients is of increasing relevance due to the impacts of climate change. We analysed European ringing data to measure the direction of phenotypic variation along...

Wealth, water and wildlife: Landscape aridity intensifies the urban luxury effect

Dan Chamberlain, Chevonne Reynolds, Arjun Amar, Dominic Henry, more

Global Ecology and Biogeography > 29 > 9 > 1595 - 1605

Aim Urban biodiversity, and its associated ecosystem services, is an important component of the quality of life of urban residents. The "luxury effect" posits a positive association between biodiversity and socioeconomic status in urban areas, and is thus reflective of environmental injustice, as the benefits associated with biodiversity are not equitably shared across society. We aimed...

Species interactions and climate change: How the disruption of species co‐occurrence will impact on an avian forest guild

Mattia Brambilla, Davide Scridel, Gaia Bazzi, Luca Ilahiane, more

Global Change Biology > 26 > 3 > 1212 - 1224

Interspecific interactions are crucial in determining species occurrence and community assembly. Understanding these interactions is thus essential for correctly predicting species' responses to climate change. We focussed on an avian forest guild of four hole‐nesting species with differing sensitivities to climate that show a range of well‐understood reciprocal interactions, including facilitation,...

Behavioural responses to human disturbance in an alpine bird

Cristina Vallino, Enrico Caprio, Fabrizio Genco, Dan Chamberlain, more

Journal of Ornithology > 2019 > 160 > 3 > 763-772

Mountain habitats are threatened by several factors, including human activities at high elevation, although the negative impacts can sometimes be balanced by positive effects related to human presence. However, knowledge of such interactions is limited in alpine ecosystems. In the study reported here, we assessed the extent of behavioural responses of the Alpine Chough Pyrrhocorax graculus, a bird...

article

A review and meta‐analysis of the effects of climate change on Holarctic mountain and upland bird populations

Davide Scridel, Mattia Brambilla, Kathy Martin, Aleksi Lehikoinen, more

Ibis > 160 > 3 > 489 - 515

Mountain regions are globally important areas for biodiversity but are subject to multiple human‐induced threats, including climate change, which has been more severe at higher elevations. We reviewed evidence for impacts of climate change on Holarctic mountain bird populations in terms of physiology, phenology, trophic interactions, demography and observed and projected distribution shifts, including...

The contribution of broadscale and finescale habitat structure to the distribution and diversity of birds in an Alpine forest-shrub ecotone

Susanne Jähnig, Riccardo Alba, Cristina Vallino, Domenico Rosselli, more

Journal of Ornithology > 2018 > 159 > 3 > 747-759

In a mountain context, the forest-shrub ecotone is an area of high biodiversity. Relatively little is known about the habitat requirements of birds in this habitat, yet it is facing potential threats from changes in grazing practices and climate change. Moreover, it is not clear at which scale habitat associations should be assessed in Alpine birds. Further information on key habitat components affecting...

Disentangling the effects of genetic and environmental factors on movement behaviour

Giulia Bombieri, Antonio Fasciolo, Vincenzo Penteriani, Juan Carlos Illera, more

Ethology > 124 > 3 > 139 - 148

Individual variability in animal movement behaviour is well documented for many species. However, it remains unclear whether this variability reflects genetic variation, environmental variation or a combination of the two. Here, we conduct a cross‐fostering experiment with the aim of investigating the role of these two components in movement patterns during the post‐fledging dependence period and...

A spatially explicit definition of conservation priorities according to population resistance and resilience, species importance and level of threat in a changing climate

Mattia Brambilla, Enrico Caprio, Giacomo Assandri, Davide Scridel, more

Diversity and Distributions > 23 > 7 > 727 - 738

Aim Human‐induced climate change requires conservation strategies incorporating its potential effects on species and communities. Key components of population persistence can be attributed to resistance (the capacity to remain unaffected) or resilience (capacity to absorb and recover) to climate change. In situ climatic refugia can act as resistant distribution units, and ex situ climatic refugia...

Trends in bird species richness, abundance and biomass along a tropical urbanization gradient

Dan Chamberlain, Micheal Kibuule, Roger Skeen, Derek Pomeroy

Urban Ecosystems > 2017 > 20 > 3 > 629-638

Impacts of urbanization on biodiversity are commonly studied using urbanization gradients which provide a space-for-time substitution in estimating consequences of urban expansion. Rates of urbanization and human population growth are high in tropical countries of the developing world, which also hold most of the world’s biodiversity hot-spots, yet few studies have considered biodiversity trends along...

Foraging habitat selection by Alpine White-winged Snowfinches Montifringilla nivalis during the nestling rearing period

Mattia Brambilla, Matteo Cortesi, Federico Capelli, Dan Chamberlain, more

Journal of Ornithology > 2017 > 158 > 1 > 277-286

High-elevation species are expected to be vulnerable to climate warming and to experience dramatic range contractions in the coming decades. Indeed, climate change in high-altitude biota has proceeded at a faster pace compared to lowlands. Understanding basic ecological features of mountain species, such as their foraging ecology, may be useful to further our understanding of the mechanisms dictating...

Alpine bird distributions along elevation gradients: the consistency of climate and habitat effects across geographic regions

Dan Chamberlain, Mattia Brambilla, Enrico Caprio, Paolo Pedrini, more

Oecologia > 2016 > 181 > 4 > 1139-1150

Many species have shown recent shifts in their distributions in response to climate change. Patterns in species occurrence or abundance along altitudinal gradients often serve as the basis for detecting such changes and assessing future sensitivity. Quantifying the distribution of species along altitudinal gradients acts as a fundamental basis for future studies on environmental change impacts, but...
