At the tipping point: Can biodiversity and rural livelihoods endure uncontrolle...
Guedes, Patrícia; Palmeirim, Ana Filipa; Monteiro, Filipa; Catarino, Luís; Palma, Luís; Temudo, Marina P.; Henriques, Mohamed; Beja, PedroOur commentary explores the increase in cashew cultivation across West Africa, drawing attention to its impacts on biodiversity and livelihoods. We summarize the issue regionally, then showcase Guinea-Bissau, where we unravel the dynamics between cashew expansion, habitat and biodiversity loss, and livelihoods. Finally, we propose concrete policy measures encompassing strengthened conservation, sustainable land...
Evaluating public interest in protected areas using Wikipedia page views
Guedes-Santos, Jhonatan; Correia, Ricardo A.; Jepson, Paul; Ladle, Richard J.Protected Areas (PAs) are the cornerstone of global conservation action and the most effective strategy for conserving the Earth’s biodiversity. Nevertheless, there is evidence that PAs are increasingly viewed by politicians and policy-makers as opportunity costs that constrain economic development. In the absence of societal resistance (‘push-back’) in the form of campaigns and/or lobbying, such attitudes leav...
Taxonomic bias in amphibian research: are researchers responding to conservatio...
Silva, Arthur F. da; Malhado, Ana C.M.; Correia, Ricardo A.; Ladle, Richard J.; Vital, Marcos V.C.; Mott, TamíAmphibians are very diverse, widely distributed, and the most endangered class of vertebrates. As with other taxa, effective conservation of amphibians needs to be supported by detailed scientific knowledge. However, species rich and broadly distributed taxa are typically characterized by high variability in research effort. Our objective was therefore to understand which factors (ecological and cultural) have ...
Perceptions of Amazonian deforestation in the British and Brazilian media
Malhado, Ana Claudia Mendes; Ladle, Richard J.; Todd, Peter A.; Malhado, Acacia C. M.A floresta Amazônica abrange mais de 6 milhões de km2 e engloba 9 países. Acredita-se que 18% da superficie florestal já tenha sido desmatada principalmente para usos agropecuários. No Brasil, a pecuária e a produção de soja encabeçam as causas do desmatamento, sendo estes responsáveis por 75% das terras desmatadas. A situação da Amazônia ilustra o principal dilema que enfrentam os ambientalistas em todo o mund...
Design solutions to coastal human-wildlife conflicts
Ladle, Richard J.; Osman, Layla P.; Rosas, Nicolás Arévalo; Bernstein, Meredith RootCoastal areas can be a challenge for conservation due to multiple competing land uses including development, tourism, and extractive resource use. These multiple land uses often lead to human-wildlife conflicts. Here we propose that collaboration with industrial designers and architects has the potential to generate innovative and effective solutions to coastal human-wildlife conflicts. Many products for modify...
Conservation by Design
Ladle, Richard J.; Root-Bernstein, MeredithConservation researchers are increasingly aware of the need to conduct interdisciplinary research and to engage nonscientists in practical applications of conservation biology. But so far, industrial designers have been left out of such collaboration and outreach efforts. Conservation of wildlife often depends on products such as nest boxes, feeders, barriers, and corridors, all of which have a designed compone...

Functional biogeography of oceanic islands and the scaling of functional divers...
Whittaker, Robert J.; Rigal, François; Borges, Paulo A. V.; Cardoso, Pedro; Terzopoulou, Sofia; Casanoves, Fernando; Pla, Laura; Guilhaumon, FrançoisAnalyses of species-diversity patterns of remote islands have been crucial to the development of biogeographic theory, yet little is known about corresponding patterns in functional traits on islands and how, for example, they may be affected by the introduction of exotic species. We collated trait data for spiders and beetles and used a functional diversity index (FRic) to test for nonrandomness in the contrib...
Frequently asked questions about in vivo chlorophyll fluorescence: practical is...
Kalaji, Hazem M.; Schansker, Gert; Ladle, Richard J.; Goltsev, Vasilij; Bosa, Karolina; Allakhverdiev, Suleyman I.; Brestic, Marian; Bussotti, FilippoThe aim of this educational review is to provide practical information on the hardware, methodology, and the hands on application of chlorophyll (Chl) a fluorescence technology. We present the paper in a question and answer format like frequently asked questions. Although nearly all information on the application of Chl a fluorescence can be found in the literature, it is not always easily accessible. This pape...
Extinction debt on oceanic islands
Triantis, Kostas A.; Borges, Paulo A. V.; Ladle, Richard J.; Hortal, Joaquín; Cardoso, Pedro; Gaspar, Clara; Dinis, Francisco; Pereira, EnésimaHabitat destruction is the leading cause of species extinctions. However, there is typically a time-lag between the reduction in habitat area and the eventual disappearance of the remnant populations. These “surviving but ultimately doomed” species represent an extinction debt. Calculating the magnitude of such future extinction events has been hampered by potentially inaccurate assumptions about the slope of s...
