Radial growth patterns associated with tree mortality in Nothofagus pumilio forest
(Molecular Diversity Preservation International, 2019-06)
Tree mortality is a key process in forest dynamics. Despite decades of effort to understand this process, many uncertainties remain. South American broadleaf species are particularly under-represented in global studies on ...
Hydraulic dysfunction due to root-exposure-initiated water stress is responsible for the mortality of Salix gordejevii shrubs on the windward slopes of active sand dunes
(Springer, 2020-11)
Aims: Sand-fixing shrub Salix gordejevii plays an important role in sand dune stabilization but often shows severe decline and mortality on the windward slopes of active dunes. The objective of this study was to explore ...
Pollinator declines and the stability of plant–pollinator networks
(Wiley, 2020-04)
Population declines of pollinators constitute a major concern for the fate of biodiversity and associated ecosystem services in a context of global change. Massive declines of pollinator populations driven by habitat loss, ...
Role of abiotic factors in Nothofagus pumilio forest mortality: The sensitivity of ecotones
(Elsevier Science, 2021-08)
The world's forests are being affected by a changing climate. Recently, patches of dead trees have been found in forests of the Patagonian endemic species Nothofagus pumilio, which could not be related to insects or ...

Effects of osmotic and thermal shock on the invasive aquatic mudsnail Potamopyrgus antipodarum: Mortality and physiology under stressful conditions
(Pensoft Publishers, 2020-01)
Invasive freshwater species, such as the exotic mollusc Potamopyrgus antipodarum (New Zealand mudsnail), can frequently survive under harsh conditions, including brackish and hypoxic environments. We experimentally assessed ...
Sapwood-inhabiting mycobiota and Nothofagus tree mortality in Patagonia: diversity patterns according to tree species, plant compartment and health condition
(Elsevier, 2020-04)
Temperate forests ecosystems are threatened by declines and diseases worldwide. Causes have been investigated during the last decades allowing, in some cases, to relate such deterioration to climate change or pathogens ...
Indicadores del decaimiento en bosques de Nothofagus pumilio en el norte de la Patagonia, ArgentinaDecline indicators of for Nothofagus pumilio forests in northern Patagonia, Argentina
(Instituto de Ecología A.C., 2018-05)
El decaimiento forestal está frecuentemente asociado a la mortalidad parcial o total de las copas en un alto porcentaje de individuos de un rodal. Si bien el decaimiento ha sido documentado a escala global, las relaciones ...
