Article
The ecological mechanisms that regulate seeding processes in temperate forests are poorly understood especially in the Southern Hemisphere. We studied the effect of different growing season metrics determined by the Normalized Difference Vegetation Index (NDVI) across eight annual periods between 2012 and 2020. We analyzed the seed production and b...

Background It is necessary to determine the implications for managing forest stands using variable retention harvesting for maintaining carbon and for calculating the effects of different harvesting practices on above- and below-ground carbon balance in forest ecosystems. In this context, forest carbon management has gained more attention among man...

Article
Full-text available
Continuous large forests intermingled with small patches of open ecosystems (e.g. peatlands) are typical in temperate mountain regions. They are usually removed when cities are installed, but patches remain inside. Moreover, the constant growth of cities threatens the surrounding natural landscapes. Urbanization and land-use change generates degrad...

Key Message Seed fall and leaf litter production are linked by a source–sink limitation relationship in unharvested areas. The magnitude of these relationships varied differently according to the retention levels over the years-after-harvesting. Abstract Seed fall and leaf litter influence forest regeneration, nutrient cycling, and other key ecolo...

Soil organic carbon (SOC) content supports several ecosystem services. Quantifying SOC requires: (i) accurate C estimates of forest components, and (ii) soil estimates. However, SOC is difficult to measure, so predictive models are needed. Our objective was to model SOC stocks within 30 cm depth in Patagonian forests based on climatic, topographic...
Article
Historically, wildfires have occurred infrequently in the Subantarctic forests on the island of Tierra del Fuego in southern Argentina: wildfires on the landscape are sporadic and exclusively human-caused. As a result of this, post-fire effects on native vegetation are largely unknown. In November of 2008, a wildfire started near a sawmill in the c...

Most of the native forests in Argentina are used for livestock production with little sustainable silvopastoral management. Our objective here is to discuss different management strategies where natural and human capital are combined to co-produce ecosystem services (ES) provided by silvopastoral systems in native forests, interacting with differen...

The objective of this work was to determine the impacts of wildfire on microsite type and abundance in N. pumilio-dominated forests. During the summer of 2021-2022 (December-March), we established 96, 100 m2 plots in burned and unburned (control) N. pumilio forests. Microsite type (eg., grass, bush, downed log) and abundance were recorded at 100 po...

Sustainable forest management is proposed as a solution for many ecological and socio-economic trade-offs associated with different forest uses. In Patagonia, silvopastoral systems were proposed to balance provisioning ecosystem services and other natural values. However, the design of these practices needs a better understanding of livestock produ...

Los bosques australes de Argentina están en su mayoría representados por especies latifoliadas del género Nothofagus, conformando bosques puros y mixtos. Existen pocos estudios ecológicos sobre la araneofauna de estos bosques. En este trabajo se analizó la diversidad (abundancia, riqueza, índices de diversidad y composición) de arañas colectadas en...

Las especies exóticas producen un desequilibrio en la naturaleza. Al no pertenecer a su hábitat original, tienen pocos depredadores, lo que suele llevar a una rápida proliferación que comúnmente desencadena una amenaza para el ecosistema. Investigadores evaluaron el conejo europeo y su potencial impacto en los bosques patagónicos (Fig. 1). Fig. 1....

Background The European rabbit ( Oryctolagus cuniculus L. 1758) was introduced into different regions of the world, generating significant trade-offs that critically impacted native vegetation. Here, we evaluate the rabbit's forage intakes in three vegetation types (forests, shrublands, and grasslands) along the four seasons in a temperate forest l...

In forests affected by heavy fires and continuous grazing of exotic herbivorous mammal species, Nothofagus pumilio (lenga) cannot recover naturally. The main factors that hinder the natural recovery of these forests and the feasibility of native tree plantations are the exotic herbivorous pressure, like that produced by Lepus europaeus (European ha...

In the last years, different spatial analyses were developed to support multi-taxon biodiversity conservation strategies. In fact, the use of species distribution models as input allowed to create spatial decision-support maps. Of special interest are maps of potential biodiversity (MPB), which define distribution and ecological requirements of rel...

Ushuaia, a coastal city located in Patagonia, Argentina, amid unique natural habitats such as sub-antarctic Nothofagus forests and Sphagnum peatlands, preserves green areas of natural ecosystems within the urban matrix. Forests and peatlands have persisted as natural islands of different sizes, conservation status and anthropic disturbances. These...

Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long-lived plants requires direct observation over many years and such datasets have rarely been made publicly available. Here we introduce MASTREE+, a dataset that collates reproductive time-series d...

Key message Flower to fruits × and seed-to-seedling were the most critical transition in the early regeneration cycle of pure and mixed Nothofagus forests, both in coastal and mountain geographic locations. Within mixed forest, the deciduous N. pumilio shows better recruitment performance (e.g., highest transition probabilities) than the evergreen...

One reason for the decline of natural forest is that many ecosystem services (ESs) are usually not priced and values were only considered provisioning services. Argentina enacted the National Law 26,331/07, which regulates protection, enrichment, restoration and management of native forests and its environmental services. The objective is to determ...
