Publication trends in global biodiversity research on protected areas

One of the main strategies to reduce the global loss of biodiversity has been the establishment of protected areas (PAs). High quality biodiversity knowledge is essential to successfully design PAs and PA networks, and to assess their conservation effectiveness. However, biodiversity knowledge is taxonomically and geographically biased. Even though PAs are typically more intensively surveyed than surrounding landscapes, they cannot avoid biodiversity knowledge shortfalls and biases. To investigate this, we performed a systematic literature review to assess publication trends in global biodiversity research taking place in PAs. Our data indicate that animals are more studied than plants, with vertebrates overrepresented in relation to invertebrates. Biodiversity in PAs has been mainly measured taxonomically (species richness or species diversity), while functional and phylogenetic diversity have rarely been considered. Finally, as predicted, there was a geographic bias towards European and USA terrestrial protected areas. These observed trends mirror more general studies of biodiversity knowledge shortfalls and could have direct negative consequences for conservation policy and practice. Reducing these biases and shortfalls is essential for more effective use of limited conservation resourcesSLC was supported by a FPI predoctoral grant financed by the Autonoma ´ University of Madrid.

Taxonomic bias in amphibian research : Are researchers responding to conservation need?

Amphibians 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 led some amphibian species to be more researched than others. We used two proxies of research effort: i) the total number of articles on Web of Science (WoS) that mention the scientific name (or synonyms) of each species, and; ii) the number of conservation science articles on WoS that mention the scientific name (or synonyms) of each species. These measures were used as dependent variables in zero hurdle regression models with the aim of identifying the most important factors driving species-level knowledge production. Well researched species (generally, and for conservation) tend to have a longer history of scientific research, come from countries with high scientific capacity, have large body size, and to be present in man-made habitats. Endangered species tend to be less researched, generally and for conservation, possibly because they are often more difficult to study: many endangered amphibians are restricted to small, fragmented and remote habitats in countries with low scientific capacity. We conclude with a discussion of how taxonomic biases in research effort on amphibians can be addressed given the limited funds available for conservation research.Peer reviewe

Genetic improvement and population structure of the Nelore breed in Northern Brazil

O objetivo deste trabalho foi avaliar a estrutura populacional e o progresso genético e fenotípico da raça Nelore na Região Norte do Brasil. Informações sobre o pedigree foram analisadas em animais nascidos entre 1942 e 2006. A estrutura populacional foi estimada utilizando-se o programa Endog. Dos 140.628 animais avaliados, 67,7% dos pais, 14,52% dos avós e 3,18% dos bisavós eram conhecidos. O coeficiente de parentesco médio e a endogamia foram, em geral, baixos: 0,13 e 0,20%, respectivamente. Contudo, esses parâmetros podem ter sido subestimados, já que as informações de pedigree eram incompletas. O número efetivo de fundadores foi de 370 e a variabilidade genética na população explicada pelos 10, 50 e 448 mais influentes ancestrais foi de 13,2, 28 e 50%, respectivamente. A existência de variabilidade genética indica possibilidade de aumento na produtividade por meio da seleção. Adicionalmente, estratégias de manejo para diminuir a idade ao primeiro parto e o intervalo de gerações são importantes para o melhoramento da raça.The objective of this work was to evaluate the population structure and the genetic and phenotypic progress of Nelore cattle in Northern Brazil. Pedigree information concerning animals born between 1942 and 2006 were analyzed. Population structure was performed using the Endog program. average relatedness coefficients were low: 0.2 and 0.13%, respectively. However,The effective number of founders was 370 and the genetic contribution of 10, 50 and 448 most influent ancestors explained 13.2, 28 and 50% of the genetic variability in the population, respectively. The genetic variability for growth traits and population structure demonstrates high probability of increasing productivity through selective breeding. Moreover, management strategies to reduce the currently observed age at first calving and generation intervals are important for Nelore cattle genetic improvement

Functional biogeography of oceanic islands and the scaling of functional diversity in the Azores

Analyses 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 contribution of endemic, other native (also combined as indigenous), and exotic species to functional-trait space across the nine islands of the Azores. In general, for both taxa and for each distributional category, functional diversity increases with species richness, which, in turn scales with island area. Null simulations support the hypothesis that each distributional group contributes to functional diversity in proportion to their species richness. Exotic spiders have added novel trait space to a greater degree than have exotic beetles, likely indicating greater impact of the reduction of immigration filters and/or differential historical losses of indigenous species. Analyses of species occurring in native-forest remnants provide limited indications of the operation of habitat filtering of exotics for three islands, but only for beetles. Although the general linear (not saturating) pattern of trait-space increase with richness of exotics suggests an ongoing process of functional enrichment and accommodation, further work is urgently needed to determine how estimates of extinction debt of indigenous species should be adjusted in the light of these findings

PROPOSTA METODOLÓGICA PARA PADRONIZAÇÃO DOS ESTUDOS DE ATITUDES EM COMUNIDADES ADJACENTES ÀS UNIDADES DE CONSERVAÇÃO DE PROTEÇÃO INTEGRAL NO BRASIL

A eficácia em alcançar objetivos de conservação é considerada um dos maiores desafios para a gestão de áreas protegidas. No Brasil, as unidades de conservação (UCs) de proteção integral têm um papel fundamental para conservação da biodiversidade, porém, persistem os conflitos sociais. Estes são frequentemente associados a comportamentos individuais que podem comprometer os objetivos de conservação (caça, desmatamento, etc.), resultando em crimes ambientais locais nas UCs que demandam recursos da gestão que poderiam ser investidos em outros programas e ações preventivas e de manejo. Assim, é essencial compreender melhor os fatores que moldam os comportamentos dos membros das comunidades adjacentes às UCs, pois são os principais atores do território protegido. Sendo as atitudes determinantes importantes de comportamentos individuais, o estudo destas em relação às UCs pode ter um papel crucial na gestão, constituindo ferramenta para, por exemplo: (i) avaliar a concordância entre os valores de criação da UC e os das comunidades; (ii) apoiar a implementação e monitoramento de estratégias de mudança social em relação à conservação da biodiversidade; (iii) mitigar conflitos locais; (iv) fornecer indicadores para monitorar a efetividade de ações/programas de conservação e conscientização nas comunidades; e (v) contribuir para o manejo das zonas de amortecimento. Neste artigo propomos um método baseado em pesquisa socioambiental para padronizar o estudo de atitudes em comunidades adjacentes às UCs, com ênfase nas de proteção integral. O método conta com três etapas principais: (1) preparação do questionário para estudo das atitudes baseado num modelo geral elaborado a partir da revisão de literatura; (2) desenvolvimento de um protocolo de aplicação do questionário; e (3) aplicação nas comunidades do entorno de uma unidade de conservação. Neste estudo, a formulação genérica será apresentada junto à experiência de aplicação no Parque Nacional do Catimbau (PE). Os resultados do estudo de caso evidenciaram a posição das comunidades sobre o Parque e delinearam padrões comportamentais. Por exemplo, pessoas mais jovens mostraram-se mais positivas em relação ao Parque e os agricultores mais favoráveis ao uso dos recursos naturais (madeira, lenha seca, caça). Baseado nestes dados, uma maior inclusão da sociedade em atividades diretamente relacionadas à conservação (monitoramento de espécies invasoras, zoneamento participativo, etc.) e o desenvolvimento de programas de sensibilização e educação foram sugeridos aos gestores da UC para aproximar as comunidades e as pessoas que se mostraram menos positivas com relação ao Parque

No visit, no interest: How COVID-19 has affected public interest in world's national parks

The use of digital content has become a powerful tool to evaluate and track macro-scale trends in human-nature relations. This is an emerging field of study known as conservation culturomics, that seeks to understand human culture through quantitative analysis in large bodies of digital content. Here, we used relative search volume on Google Search as a culturomic metric of public interest to investigate the global impact of the 2020 COVID-19 pandemic on national parks (NPs). Specifically, we focus on the impacts of limiting people?s mobility (through social isolation and lock-down measures) on public interest in NPs, since this is likely to have a strong causal relationship with park visitation. We generated public interest data for 2411 NPs from around the world for the period January 2016 to July 2020, to explore the relationship between relative search volume and periods of greater and lesser mobility restrictions due to the COVID-19 pandemic. We observed a global trend of declining public interest in national parks during the initial phase of the coronavirus pandemic, although there was considerable variation between both parks and countries. For example, contrary to the global trend public interest in NPs increased in Finland during the first lock-down. Significantly, countries whose national parks are highly dependent on international visitors (e.g., South Africa and India) had very severe declines in public interest. Our study reinforces the key role that visitation plays in driving public interest in national parks and illustrates the utility of culturomic methods for monitoring human-park interactions at scale.Peer reviewe

Transience of public attention in conservation science

Societal awareness of, and engagement with, environmental problems is a critical prerequisite for effective conservation programs. Research has revealed a strong general pattern whereby public attention received by cultural products diminishes over time. If transposed to conservation, this transience of societal attention is likely to be of major importance because it can limit motivation to support conservation efforts. We address the concept of attention transience applied to conservation, discuss its major drivers and mechanisms, and provide a short overview of conservation issues for which this phenomenon is expected to be particularly relevant. Attention transience leaves a brief window of opportunity for conservationists to focus public awareness and to mobilize necessary support. In this context, it is critical to maximize the conservation benefits generated during these short bursts of attention, especially through tailored conservation marketing campaigns with targeted message framing and regular efforts to refocus attention on key issues

A big data approach to identify the loss of coastal cultural ecosystem services caused by the 2019 Brazilian oil spill disaster

In August 2019, the Northeast coast of Brazil was impacted by an extensive oil spill, with immediate effects on marine and coastal ecosystems and significant impacts on tourism and food security. The human dimension of those impacts also includes the loss of cultural ecosystem services (CES); the non-material benefits stemming from strongly rooted cultural practices and relationships with nature. CES are of great importance for local residents and visitors that flock to Brazilian iconic beaches, however, they are difficult to measure using traditional assessment methods due to their subjective and non-tangible nature. Here, we use a big data approach to assess and map the loss of CES in the Northeast coast of Brazil caused by the recent oil spill. We analysed 2,880 digital images (published on the image sharing platform Flickr) taken before and during the disaster in affected locations, using a combination of automated techniques. Results showed a sharp decline in the number of users posting photos of locations affected by oil spill, and a decline in photos representing landscape and cultural appreciation. Our big data approach provides a fast and automated way to assess CES at large spatial scales that can be used to monitor the social impacts of environmental disasters.Peer reviewe
