Qualitative measures of resprouting capacity often fail to capture inter-and intra-species variation, whereas available quantitative methods can be complex and time-consuming, hindering broad-scale comparative studies. Here, we propose two quantitative indices that can be applied in a standard way in different regions. We sampled 1046 plants of 20...

Cacti are conspicuous plants across arid and semi‐arid ecosystems of the American continent and are currently under threat due to human pressures, such as habitat loss, illegal collection and changes in fire regimes. Although much of their habitat is highly fire prone, there are strikingly few studies on their germination response to fire cues. The...

Background Fire is an important driver of ecosystem dynamics worldwide. However, knowledge on broad-scale patterns of ecosystem and organism responses to fires is still scarce. Through a systematic quantitative review of available studies across South America, we assessed fire effects on biodiversity and abundance of different organisms ( i.e., pla...

Effective policies to halt biodiversity loss require knowing which anthropogenic drivers are the most important direct causes. Whereas previous knowledge has been limited in scope and rigor, here we statistically synthesize empirical comparisons of recent driver impacts found through a wide-ranging review. We show that land/sea use change has been...

Plant fire syndromes are usually defined as combinations of fire response traits, the most common being resprouting (R) and seeding (S). Plant flammability (F), on the other hand, refers to a plant's effects on communities and ecosystems. Despite its important ecological and evolutionary implications, F has rarely been considered to define plant fi...

A pesar de la relevancia ecológica de los cactus en los ecosistemas secos del continente americano, los estudios sobre los efectos del fuego en este importante taxón son escasos, especialmente en cactus arborescentes. Trichocereus terschekii es una especie clave de la ecorregión de la Prepuna en el noroeste de Argentina, por su valor cultural, econ...

Flammability is a fundamental trait relevant from individual plants to landscape level, and with evolutionary and ecological implications. In a context of accelerating human-driven environmental change, which often increases the frequency and extent of fires, flammability appears as a priority for many stakeholders in different regions of the world...

Multicultural representation is a stated goal of many global scientific assessment processes. These processes aim to mobilize a broader, more diverse knowledge base and increase legitimacy and inclusiveness of these assessment processes. Often, enhancing cultural diversity is encouraged through involvement of diverse expert teams and sources of kno...

En el año 2020 los incendios en Córdoba alcanzaron magnitudes extremas, reavivando la discusión sobre sus causas, su impacto en los ecosistemas y las políticas públicas en torno a su manejo en el paisaje. Si bien los ecosistemas de Córdoba están adaptados a regímenes naturales históricos de fuego, la creciente presión humana los ha modificado drást...

Synthesis of science to develop broad understandings requires integration of information from multiple scales and diverse sources. Inherent biases in scientific work favor English-language literature and Anglophone experts. This limits what is included as ‘knowledge’ and narrows our understanding of important issues. These data were collected to ex...

Este artículo de divulgación es un emergente del Simposio Rol ecológico y evolutivo del fuego sobre los ecosistemas argentinos realizado en el marco de las 37º Jornadas Argentinas de Botánica, el 10 de septiembre de 2019, en San Miguel de Tucumán, Argentina. Las personas usualmente conciben los incendios como catástrofes naturales, con efectos neg...

Los recientes incendios en Australia han reavivado la discusión sobre el impacto del calentamiento global en los ecosistemas. Estos incendios extremos, que entre junio de 2019 y enero de 2020 quemaron aproximadamente 19 millones de hectáreas, se suman a otros recientes, como por ejemplo en la Amazonia en agosto-septiembre de 2019 (3 millones de hec...

En este artículo de divulgación discutimos la influencia del calentamiento global en la ocurrencia de incendios extremos en distintas regiones del mundo en tiempos recientes. /// In this article we discuss the influence of global warming on the occurrence of extreme fires in different regions of the world in recent times.

The main direct drivers of biodiversity loss – land/sea-use change, direct exploitation, climate change, pollution and invasive alien species – are likely to have their greatest impacts on different kinds of species and ecosystems. I will discuss the likely consequences of these ‘signatures’, combined with the drivers’ relative importance in recent...

Despite increasing scientific understanding of the global environmental crisis, we struggle to adopt the policies science suggests would be effective. One of the reasons for that is the lack of inclusive engagement and dialogue among a wide range of different actors. Furthermore, there is a lack of consideration of differences between languages, wo...

En este artículo de divulgación comparto algunas reflexiones sobre mi participación en el Informe Global sobre Biodiversidad y Servicios Ecosistémicos de la IPBES, y en el Programa de Becas de la IPBES // In this dissemination article I share some reflections on my participation in the IPBES Global Assessment on Biodiversity and Ecosystem Services,...

The ecological relevance of the study of functional diversity (FD) as a driver of ecosystem processes and ecosystem services (ES) has been widely recognized, since it has been proven to be a useful approach to understand how plants respond to different natural or anthropogenic changes and how they alter ecosystem processes determining the provision...

El fuego es un factor ecológico clave que afecta la dinámica de la vegetación. En las últimas décadas la ocurrencia de incendios en la Región Chaqueña, ha aumentado notablemente, desafiando la capacidad adaptativa de las plantas para regenerarse luego del fuego. Las especies herbáceas latifoliadas han sido poco estudiadas en comparación con las leñ...

Report of the three-day workshop and a 'Conversations with the Earth: Celebrating Biodiversity through the Arts' Evening convened at the 6 th IPBES Plenary, Medellín, Colombia (17-24 March 2018). The event brought together a global transdisciplinary team of emerging biodiversity and ecosystem services experts to shape transformative thinking about...

Fire is a key ecological factor affecting plant dynamics. In the last few decades, fire occurrence in the Chaco region has increased noticeably, challenging the adaptive capacity of plants to regenerate after a fire. Broad-leaved forb species have been much less studied than woody and graminoids, although they are an important component of fire dyn...

Early-career experts can play a fundamental role in achieving planetary sustainability by bridging generational divides and developing novel solutions to complex problems. We argue that intergenerational partnerships and interdisciplinary collaboration among early-career experts will enable emerging sustainability leaders to contribute fully to a s...

Ecological research produces a tremendous amount of data, but the diversity in scales and topics covered and the ways in which studies are carried out result in large numbers of small, idiosyncratic data sets using heterogeneous terminologies. Such heterogeneity can be attributed, in part, to a lack of standards for acquiring, organizing and descri...

Plant functional traits are the features (morphological, physiological, phenological) that represent ecological strategies and determine how plants respond to environmental factors, affect other trophic levels and influence ecosystem properties. Variation in plant functional traits, and trait syndromes, has proven useful for tackling many important...

Plant species of the Chaco seasonally dry forest of central Argentina have presumably been under a low evolutionary pressure to develop specialized fire-response traits, such as heat-stimulated germination. Nevertheless, other historical factors such as seasonal drought and/or endozoochorus dispersal could have led some species to develop heat-tole...

The objective of this dissemination booklet is to cummunicate, in a non-scientific language, the main findings and some conclusions of our research. It is aimed at producers, technicians, public servants and settlers who were involved in our study. The brohure emphasizes how each one of these groups of stakeholders has its own perception, assessmen...

El aparato comprende un cuerpo hueco soportado por patas desmontables, formado por una porción inferior [11] y otra superior [12], estando la porción su...

Fire ecology has been hindered by the lack of comparable, affordable protocols to quantify the flammability of whole plants over large numbers of species. We describe a low-tech device that can be carried to the field and that allows highly standardized measurement of the flammability of whole individuals or portions up to 70 cm long. We illustrate...

Plant-aphid-parasitoid interactions and parasitism rates were assessed in adjacent cultivated and noncultivated habitats in an organic vegetable farm in a chaco serrano woodland, Córdoba, Argentina. Seven aphid species on eight vegetable species were found in the cultivated habitat. Macrosiphum euphorbiae was present on all vegetable species. Four...

Extrafloral nectaries (EFNs) and hemipteran honeydew are liquid food rewards (FRs) that encourage ant visitation in many plant families in a wide variety of habitats. In this study we explored the diversity, distribution and interactions of exudate-gathering ants at three different liquid food rewards: nectar from EFNs on Croton sarcopetalus and ho...

Fire is an important factor shaping the structure and dynamics of plant communities worldwide. The flammability of the dominant plant species strongly determines the overall tendency of vegetation to catch and spread fire. We identify 4 components of flammability: maximum temperature reached (MTR), burning time (BT), burnt length (BL) and percentag...
