“…Cracid reintroductions have been used as a conservation tool for the restoration of threatened species, as was the case with Crax blumenbachii (São Bernardo 2012), Pipile albipennis (Angulo and Barrio 2004), and Aburria jacutinga (Oliveira et al 2016). Reintroduction and ecotourism are being carried out effectively in some parts of the Argentinean Chaco, as happens in Iberá -Corrientes province (Caruso and Jiménez Pérez 2013, Di Blanco et al 2015, Zamboni et al 2017, where local hunters started working as provincial park rangers or local guides, which created a socioeconomic change in the region. Another example of the application of these strategies is the case of the Pantanal regions (Tortato et al 2017) or the case of the Mocagua island in Colombia, where local inhabitants work as guides for tourists who travel specifically to observe and learn about the rare species Crax globulosa (Bennet 2003).…”

2018. Determining the factors that influence the occurrence of Bare-faced Curassows (Crax fasciolata) in Humid Chaco, northern Argentina. Avian Conservation and Ecology 13(2):1. https://doi. ABSTRACT. Identifying factors that determine the spatial distribution of threatened species is key to ensuring their conservation. The Bare-faced Curassow (Crax fasciolata) is a globally threatened bird that is categorized as Vulnerable, and its populations are declining in the gallery forests of the Humid Chaco. To evaluate the effect of human activities and environmental characteristics on the occupancy of Bare-faced Curassows, we sampled 48 sites along two rivers in northern Argentina. Bare-faced Curassows were recorded in 46% of the sites visited. The anthropic activities were identified as hunting pressure, selective logging of timber, and livestock production. Hunting and logging were positively associated with each other, and in turn, negatively related to village distance. We evaluated 17 occupancy models using six predictive variables. Occupancy by the Bare-faced Curassow was positively influenced by the distance to the nearest village and by forest cover. To a lesser extent, occupancy was also positively associated with an increase in availability of trees with fleshy fruits and with river course length. Our results indicate that hunting pressure and selective logging are limited by the cost of access from populated areas. Thus, distance to the villages was a good indicator of these human activities along the gallery forests and could be used to determine the spatial distribution of the Bare-faced Curassow in its southern range. Our study highlights the value of using presence/absence surveys and occupancy models for assessing threats of threatened and elusive species such as cracids. Identification des facteurs qui influent sur l'occurrence du Hocco à face nue (Crax fasciolata) dans le Chaco humide du nord de l'ArgentineRÉSUMÉ. L'identification des facteurs qui influent le plus sur la répartition spatiale d'espèces menacées est fondamentale si l'on veut assurer leur conservation. Le Hocco à face nue (Crax fasciolata) est un oiseau menacé à l'échelle planétaire et classé comme « vulnérable »; ses populations sont en diminution dans les forêts-galeries du Chaco humide. Pour évaluer l'effet des activités humaines et des caractéristiques environnementales sur la présence des Hoccos à face nue, nous avons échantillonnés 48 sites le long de deux rivières dans le nord de l'Argentine. Des Hoccos à face nue ont été trouvés dans 46 % des sites visités. Les activités d'origine anthropique qui ont été identifiées sont la pression de chasse, la coupe sélective de bois et l'élevage de bétail. La chasse et la coupe de bois étaient positivement associées l'une à l'autre, mais négativement liées à la distance d'un village. Nous avons évalué 17 modèles de présence au moyen de six variables explicatives. La présence du Hocco à face nue était positivement associée avec la distance au village le plus proche et le couvert forestier. Dan...

Rewilding is emerging as a promising restoration strategy to enhance the conservation status of biodiversity and promote self-regulating ecosystems while re-engaging people with nature. Overcoming the challenges in monitoring and reporting rewilding projects would improve its practical implementation and maximize its conservation and restoration outcomes. Here, we present a novel approach for measuring and monitoring progress in rewilding that focuses on the ecological attributes of rewilding. We devised a bi-dimensional framework for assessing the recovery of processes and their natural dynamics through (i) decreasing human forcing on ecological processes and (ii) increasing ecological integrity of ecosystems. The rewilding assessment framework incorporates the reduction of material inputs and outputs associated with human management, as well as the restoration of natural stochasticity and disturbance regimes, landscape connectivity and trophic complexity. Furthermore, we provide a list of potential activities for increasing the ecological integrity after reviewing the evidence for the effectiveness of common restoration actions. For illustration purposes, we apply the framework to three flagship restoration projects in the Netherlands, Switzerland and Argentina. This approach has the potential to broaden the scope of rewilding projects, facilitate sound decision-making and connect the science and practice of rewilding.This article is part of the theme issue ‘Trophic rewilding: consequences for ecosystems under global change’.

“…For example, we note that rapid environmental change, including extreme heat events, is an ongoing challenge to successful ecological rewilding that attempts to reduce ongoing human intervention (Corlett, 2016), despite historical calls for the development of techniques and strategies that are proactive rather than strictly reactive (Hobbs and Cramer, 2008). Recent examples and reviews have focused heavily on the use of captive populations in reintroduction and rewilding attempts (Fernandez et al, 2017;Zamboni et al, 2017), and we suggest these captive populations may be an ideal focus for future conservation applications of this study. Through the application of organismal priming (e.g.…”

Organisms increasingly encounter higher frequencies of extreme weather events as a consequence of global climate change. Currently, few strategies are available to mitigate climate change effects on animals arising from acute extreme high-temperature events. We tested the capacity of physiological engineering to influence the intra- and multi-generational upper thermal tolerance capacity of a model organism, , subjected to extreme high temperatures. Enhancement of specific physiological regulators during development could affect thermal tolerance or life-history attributes affecting subsequent fitness. Using experimental populations, we exposed F0 individuals to one of four treatments: heat hardening (28°C to 36°C, 1°C per 10 min), heat hardening plus serotonin (0.056 μg ml), heat hardening plus methionine (0.79 mg ml) and a control treatment. Regulator concentrations were based on previous literature. Serotonin may promote thermal tolerance, acting upon metabolism and life history. Methionine acts as a methylation agent across generations. For all groups, measurements were collected for three performance traits of individual thermal tolerance (upper sublethal thermal limit, lethal limit and dysregulation range) over two generations. The results showed that no treatment increased the upper thermal limit during acute thermal stress, although serotonin-treated and methionine-treated individuals outperformed controls across multiple thermal performance traits. Additionally, some effects were evident across generations. Together, these results suggest that phenotypic engineering provides complex outcomes, and if implemented with heat hardening can further influence performance in multiple thermal tolerance traits, within and across generations. Potentially, such techniques could be up-scaled to provide resilience and stability in populations susceptible to extreme temperature events.
