ReviewEcosystem services provided by wildlife in the Pampas region, Argentina
Introduction
Natural ecosystems have been increasingly threatened by anthropogenic factors (urbanization, mining, deforestation, chemical and light pollution, introduction of exotic species) all around the world (Borges et al., 2019). In particular, the expansion and intensification of agricultural activities have reduced wildlife natural habitats (Foley et al., 2005). Many of these species are been persecuted and killed by ranchers claiming them as “agricultural pests” (Abba et al., 2009, Pedrana et al., 2014, Pedrana et al., 2015, Soler et al., 2004) and others suffered from indirect effects of agricultural practices, such as poisoning or the loss and/or fragmentation of their habitats (Bilenca et al., 2012, Ogada, 2014, Ripple et al., 2015).
Wildlife species are an essential part of an ecosystem, playing different roles in the provision of Ecosystem Services (ES), defined as the benefits that humanity can obtain from a natural process of the ecosystem (Balvanera et al., 2006, Díaz et al., 2005, Green and Elmberg, 2014, Whelan et al., 2008). Consequently, the anthropogenic changes in the quality and availability of natural habitats are threatening these benefits (MEA, 2005).
There is an extensive bibliography that recognizes a great amount of ES provided by birds and mammals (Clark et al., 2016, Gaston et al., 2018, Lacher et al., 2019, Whelan et al., 2008). These groups comprise a great diversity of species with very different habitat behaviors and requirements, fulfilling important roles in the ecosystems (Davidson et al., 2012, Green and Elmberg, 2014, Sarasola et al., 2016, Whelan et al., 2008, Williams et al., 2018). These groups of animals are related to the three types of ES defined by the Common International Classification of Ecosystem Services (CICES): Provisioning; Regulation and Maintenance; and Cultural (Haines-Young and Potschin, 2013).
As Provisioning ES, birds and mammals are harvested for human consumption and subjected to sport and subsistence hunting. In addition, their feathers and leather are used for clothing and accessories (Buij et al., 2017; Green and Elmberg, 2014). Many studies highlight the role of birds and mammals in Regulation and Maintenance ES. For example, frugivorous and nectarivorous bat and lemur species regulate forest floral diversity through their role as seed dispersers and pollinators (Dew and Wright, 1998). Also, large aggregations of birds contribute to the input and nutrient flow of an ecosystem (Whelan et al., 2008), and many insectivorous and carnivorous animals (raptors, bats and carnivorous mammals) predate on detrimental special for local agriculture and livestock (Dew and Wright, 1998, Donázar et al., 2016). Finally, burrowing mammals help water filtrarion and soil mixing by building their dens (Davidson et al., 2012) and increase the organic and inorganic nutrients available in the soil, providing a better quality fodder for cattle (Villarreal et al., 2008). Lastly, birds and mammals can provide Cultural ES, by being a source of inspiration for photography and art, spiritual and cultural heritage. Also their presence encourages environmental education and eco-tourism (Dew and Wright, 1998, Green and Elmberg, 2014).
A large proportion of the Earth’s terrestrial surface is influenced by agriculture; therefore, its contribution to biodiversity is critical in long-term conservation of wildlife populations (Batáry et al., 2011, Tallis et al., 2009). In general, agroecosystems are managed to optimize provisioning ES, such as food, fiber and fuel. However, these benefits depend upon regulating ES, which are threatened by human activities (Foley et al., 2005, MEA, 2005, Rey Benayas and Bullock, 2012). Well-managed agricultural landscapes comprehend all types of services (MEA, 2005, Müller et al., 2019) and the interaction with natural areas is of great importance to achieve food security and maintain environmental integrity and resilience (Poppy et al., 2014).
Considering the huge impact that birds and mammals have on the human well-being, it is important to recognize the ES provided by these groups in agroecosystems. For this, it is useful to recognize key “ecosystem services providers”. Understanding their ecology, how animals select their resources (food and habitat) and their responses to environmental changes, could help to identify the ES provided by them, which are of importance for agricultural production and environmental integrity (Zaccagnini et al., 2011). On the other hand, it is important to take into account the negative interactions between them and people as well, because conflicts are one of the main threats that species are facing nowadays (Dickman, 2010). Therefore, having a clear identification and understanding of these relationships is crucial for the sustainable management of the environment (Birkhofer et al., 2018).
The Pampas region in Argentina is a temperate grassland ecosystem and one of the richest agricultural areas of the world for grain and beef production (Baldi et al., 2006, Bilenca and Miñarro, 2004, Soriano et al., 1991). Several areas of the original grasslands were replaced by sown pastures for livestock and croplands, with a particular expansion of soybean within the last decades (Aizen et al., 2009, Grau et al., 2005). This reduction of natural habitats has increased the overlapping between species of birds and mammals and the anthropogenic activities, threatening wildlife populations (Azpiroz et al., 2012, Codesido et al., 2011). Consequently, these changes have negatively affected the potential ES that these species could provide, even before they are identified and valued. Therefore, it is important to identify the different ES provided by birds and mammals and their conflicts to help achieve an integration between conservation and agriculture production.
The aim of this study was to identify which species are key “ecosystem services providers” of the Pampas region and highlight their potential ES provided by them. The specific objectives were: 1) to identify ecological functions of birds and mammals and their conflicts with human-activities in the Pampas region reported by previous articles; and 2) to link these ecological functions with potential ES provided by these species.

Study area
The Pampas region is located in the central east of Argentina and comprises 398966 km2 (including south of Entre Ríos, Córdoba and Santa Fe, north of La Pampa and almost the entire Buenos Aires province) (Soriano et al., 1991) (Fig. 1a). This region is divided into six ecological sub-regions according to precipitations and soil quality: Rolling Pampas, Mesopotamian Pampas, Inner Pampas, Central Pampas, Flooding Pampas and Southern Pampas (Fig. 1b) (Soriano et al., 1991). The average annual
Ecological functions provided by birds and mammals in the Pampas region
From the 145 reviewed studies, only 34% of them reported ecological functions of birds or mammals that highlight potential ES provided by them (Appendix A). Regarding the classification of ES, we identified Regulation and Maintenance in 38 studies, Cultural in 11 and Provisioning in only 3 of them (some articles mentioned more than one ES). Within all articles, 78% were about birds and the rest about mammals. In our review, we found that ecological functions of wildlife were performed in a
Conclusion
The concept of ES (MEA, 2005) provides a useful tool to bridge biodiversity conservation, ecosystem functions, human benefits and development needs (Müller et al., 2019, Tallis et al., 2009). Based on our review and in accordance with many authors around the world (Balvanera et al., 2006, Díaz et al., 2005, Green and Elmberg, 2014, Whelan et al., 2008), birds and mammals play key roles in a wide variety of ES in the Pampas region. Most of the ES found in the reviewed studies are related to

2022, Forest Ecology and ManagementCitation Excerpt :From the community-level standpoint, more nuanced assessments incorporating other facets of diversity, such as measures of alpha and beta functional and phylogenetic diversity, would provide a complementary view to bird community responses to afforestation (Boesing et al., 2018; Jacoboski and Hartz, 2020; Luck et al., 2013; Meynard et al., 2011). Furthermore, functional trait-based approaches would favor a more direct assessment of species’ functional roles onto the potential effects of afforestation on ecosystem processes and services provided by birds (Barros et al., 2019; Gavier-Pizarro et al., 2012; Gorosábel et al., 2020; Jacoboski and Hartz, 2020; Luck et al., 2013; Michel et al., 2020; Newbold et al., 2013). From a landscape perspective, information on landscape-level thresholds above which grassland bird diversity or species’ abundance may decline, leading to local or regional extinctions is needed (Boesing et al., 2018; Huggett, 2005; Melo et al., 2018; Toms and Villard, 2015).
Can rural tourism stimulate biodiversity conservation and influence farmer's management decisions?
2021, Journal for Nature ConservationCitation Excerpt :For this reason, using different tree species that provide the same services would be convenient to avoid the expansion of a pest bird. Other potential conflicts between wildlife and agricultural production should be explored to achieve landscape multifunctionality through biodiversity conservation (Gorosábel et al., 2020). It is often argued that rural tourism generates an additional income that would help to stabilize the farm's economic balance against variations of exogenous factors and create job opportunities for inactive members of the family (Ammirato et al., 2020; Beedell & Rehman, 2000; Hansson, Ferguson, Olofsson, & Rantamäki-Lahtinen, 2013; Hjalager, 1996; Ilbery, 1991; Nogar, Baldoni, & Capristo, 2007; Ollenburg & Buckley, 2007).
