“…While protected areas are a primary conservation measure (Ziller and Dechoum, 2013), anthropogenic modifications of the surrounding area can hamper the management of the remnant ecosystems (McDonald et al, 2009). The fragmentation and modification of landscapes lead to the isolation of protected areas, turning them into virtual islands of remnant habitat set within an impacted matrix, making the reserves ever more vulnerable to external processes, such as invasion by exotic species (Spear et al, 2013). In the specific case of the SANR, these problems may be mediated through the implementation of specific conservation and management measures, such as the prevention of wildfires, fencing, hunting controls, and environmental education, initiatives that validate the status of the reserve as an advanced outpost of the Caatinga Biosphere Reserve.…”

The Caatinga is an exclusively Brazilian biome that covers approximately 11% of the country and is currently vulnerable to a series of impacts. Its biodiversity is relatively poorly-known, and few data are available on most groups of fauna, hampering the reliable identification of priority areas for conservation. The present study describes the species composition and diversity of the nonvolant mammal community from the Serra das Almas Nature Reserve, an advanced outpost of the Caatinga Biosphere Reserve. Data on small mammals (rodents and marsupials) were collected using live traps. Data on medium -and large -bodied mammals were obtained through observations in the field, photographic records, specimens donated by local residents, and indirect evidences. In addition, camera traps were installed along trails and near water bodies. The analysis of 520 individual records yielded a list containing 29 species of nonvolant mammals. Estimated species richness for the study area was 21±8. The species richness recorded in the SANR represents from one-third to one-half of the nonvolant mammals found in the Caatinga, based on the most recent estimates.Keywords: inventory, camera trap, Serra das Almas, Ceará. ResumoA Caatinga é um bioma exclusivamente brasileiro que cobre aproximadamente 11% do território do país, sendo vulnerável a uma série de impactos. Sua biodiversidade é relativamente pouco conhecida, e poucos dados estão disponíveis para vários grupos zoológicos, dificultando a identificação confiável de áreas prioritárias para a conservação. O presente estudo descreve a composição e diversidade de espécies da comunidade de mamíferos não voadores da Reserva Serra das Almas, um posto avançado da Reserva da Biosfera. Dados sobre pequenos mamíferos (roedores e marsupiais) foram coletados utilizando-se armadilhas. Dados sobre mamíferos de médio e grande porte foram obtidos por meio de observações diretas, registros fotográficos e recebimento de material doado por moradores, além de registro de evidências indiretas, como pegadas e fezes. Além disso, foram utilizadas armadilhas fotográficas instaladas ao longo de trilhas e próximas à corpos d'água. A análise de 520 registros individuais resultou em uma lista de 29 espécies de mamíferos não voadores. A riqueza de espécies estimada para a área de estudo foi 21±8, valor que representa de um terço à metade dos mamíferos encontrados na Caatinga, baseado nas mais recentes estimativas.Palavras-chave: inventário, armadilha fotográfica, Serra das Almas, Ceará.

“…susceptible sites, include sites that are most exposed to invasion, such as those associated with high human activity (high exposure). Susceptible sites are also areas where invasive species are likely to establish and spread (invasible areas, sensu Catford et al 2011), such as highly disturbed areas (D'Antonio et al 1999), or those surrounded by high population density (Spear et al 2013). For example, Gallardo and Aldridge (2013) quantified the risk of establishment and spread of 16 aquatic species in Britain using multiple modelling approaches, including climate matching.…”

Prioritization is indispensable for the management of biological invasions, as recognized by the Convention on Biological Diversity, its current strategic plan, and specifically Aichi Target 9 that concerns invasive alien species. Here we provide an overview of the process, approaches and the data needs for prioritization for invasion policy and management, with the intention of informing and guiding efforts to address this target. Many prioritization schemes quantify impact and risk, from the pragmatic and action-focused to the data-demanding and science-based. Effective prioritization must consider not only invasive species and pathways (as mentioned in Aichi Target 9), but also which sites are most sensitive and susceptible to invasion (not made explicit in Aichi Target 9). Integrated prioritization across these foci may lead to future efficiencies in resource allocation for invasion management. Many countries face the challenge of prioritizing with little capacity and poor baseline data. We recommend a consultative, science-based process for prioritizing impacts based on species, pathways and sites, and outline the information needed by countries to achieve this. This should be integrated into a national process that incorporates a broad suite of social and economic criteria. Such a process is likely to be feasible for most countries.

“…Anthropogenic activities, such as agriculture and forestry in regions surrounding PAs, further promote the introduction of IPS Melin et al, 2014;McConnachie et al, 2015). Intensive anthropogenic activities inside PAs and in adjacent areas greatly increase the number of pathways for IPS (Spear et al, 2013;McConnachie et al, 2015). As habitat suitability for IPS shifts with climate change, the natural dispersal of IPS, as opposed to the anthropogenic dispersal, could also promote invasion into PAs (www.issg.org).…”

Abstract. Global climate change may enable invasive plant species (IPS) to invade protected areas (PAs), but plant invasion on a global scale has not yet been explicitly addressed. Here, we mapped the potential invasion pathways for IPS in PAs across the globe and explored potential factors determining the pathways of plant invasion under climate change. We used species distribution modelling to estimate the suitable habitats of 386 IPS and applied a corridor analysis to compute the potential pathways of IPS in PAs under climate change. Subsequently, we analysed the potential factors affecting the pathways in PAs. According to our results, the main potential pathways of IPS in PAs are in Europe, eastern Australia, New Zealand, southern Africa, and eastern regions of South America and are strongly influenced by changes in temperature and precipitation. Protected areas can play an important role in preventing and controlling the spread of IPS under climate change. This is due to the fact that measures are taken to monitor climate change in detail, to provide effective management near or inside PAs, and to control the introduction of IPS with a high capacity for natural dispersal. A review of conservation policies in PAs is urgently needed.
