Integrating local pastoral knowledge, participatory mapping, and species distribution modeling for risk assessment of invasive rubber vine (Cryptostegia grandiflora) in Ethiopia’s Afar region Ecology and Society
Luizza, Matthew W.; Colorado State University, Natural Resource Ecology Laboratory; mwluizza@rams.colostate.edu; Wakie, Tewodros; Colorado State University, Natural Resource Ecology Laboratory; tewodros.wakie@colostate.edu; Evangelista, Paul H.; Colorado State University, Natural Resource Ecology Laboratory; paul.evangelista@colostate.edu; Jarnevich, Catherine S.; U.S. Geological Survey, Fort Collins Science Center; jarnevichc@usgs.gov.
The threats posed by invasive plants span ecosystems and economies worldwide. Local knowledge of biological invasions has proven beneficial for invasive species research, but to date no work has integrated this knowledge with species distribution modeling for invasion risk assessments. In this study, we integrated pastoral knowledge with Maxent modeling to assess the suitable habitat and potential impacts of invasive Cryptostegia grandiflora Robx. Ex R.Br. (rubber vine) in Ethiopia’s Afar region. We conducted focus groups with seven villages across the Amibara and Awash-Fentale districts. Pastoral knowledge revealed the growing threat of rubber vine, which to date has received limited attention in Ethiopia, and whose presence in Afar was...

Integrating research tools to support the management of social-ecological systems under climate change Ecology and Society
Miller, Brian W.; Department of the Interior North Central Climate Science Center, Natural Resource Ecology Laboratory, Colorado State University; brian.miller@colostate.edu; Morisette, Jeffrey T.; Department of the Interior North Central Climate Science Center, Natural Resource Ecology Laboratory, Colorado State University; U.S. Geological Survey; morisettej@usgs.gov.
Developing resource management strategies in the face of climate change is complicated by the considerable uncertainty associated with projections of climate and its impacts and by the complex interactions between social and ecological variables. The broad, interconnected nature of this challenge has resulted in calls for analytical frameworks that integrate research tools and can support natural resource management decision making in the face of uncertainty and complex interactions. We respond to this call by first reviewing three methods that have proven useful for climate change research, but whose application and development have been largely isolated: species distribution modeling, scenario planning, and simulation modeling. Species distribution...

Climate and land-use changes effects on the distribution of a regional endemism: Melanophryniscus sanmartini (Amphibia, Bufonidae) Iheringia, Sér. Zool.
Rosenstock,Nicole; Toranza,Carolina; Brazeiro,Alejandro.
ABSTRACT Amphibians are the most threatened vertebrate group according to the IUCN. Land-use and land cover change (LULCC) and climate change (CC) are two of the main factors related to declining amphibian populations. Given the vulnerability of threatened and rare species, the study of their response to these impacts is a conservation priority. The aim of this work was to analyze the combined impact of LULCC and CC on the regionally endemic species Melanophryniscus sanmartini Klappenbach, 1968. This species is currently categorized as near threatened by the IUCN, and previous studies suggest negative effects of projected changes in climate. Using maximum entropy methods we modeled the effects of CC on the current and mid-century distribution of M....

Geographical differences in habitat relationships of cetaceans across an ocean basin ArchiMer
Mannocci, Laura; Roberts, Jason J.; Pedersen, Eric J.; Halpin, Patrick N..
The distributions of highly mobile marine species such as cetaceans are increasingly modeled at basin scale by combining data from multiple regions. However, these basin‐wide models often overlook geographical variations in species habitat relationships between regions. We tested for geographical variations in habitat relationships for a suite of cetacean taxa between the two sides of the North Atlantic basin. Using cetacean visual survey data and remote sensing data from the western and eastern basin in summer, we related the probability of presence of twelve cetacean taxa from three guilds to seafloor depth, sea surface temperature and primary productivity. In a generalized additive model framework, we fitted 1) basin‐wide (BW) models, assuming a single...

Future uncertainties for the distribution and conservation of Paubrasilia echinata under climate change Acta Botanica
Esser,Luíz Fernando; Saraiva,Daniel Dutra; Jarenkow,João André.
ABSTRACT Paubrasilia echinata is a widely cultivated endangered tree species with small populations restricted to a narrow strip of habitats along the Brazilian coast. The potential impacts of climate change on the distribution of P. echinata have yet to be investigated, and so it remains unknown whether protected areas will ensure the persistence of the species in the future. Here, we estimate the impacts of climate change on the distribution of P. echinata inside and outside of protected areas considering different climate change scenarios and two different sets of presence records: natural distribution and cultivated records. Future scenarios showed a gradual reduction in climatically suitable area both inside and outside of protected areas. Projections...
