Novel species of fungi described in this study include those from various countries as follows:
Summary Many remnants of tropical forests are surrounded by deforested areas dominated successional vegetation. Although secondary dispersal scatter‐hoarding rodents and ants may influence seed predation seedling recruitment, very little is known about its importance in degraded forest ecosystems. We studied the effects on predation, germination recruitment primarily bird‐dispersed tree C lusia trochiformis a montane B olivia. carried out exclosure experiments that allowed or excluded access...
Abstract Shifting agriculture and anthropogenic fires are among the main causes of deforestation in tropics. After fire land abandonment, vast deforested areas commonly dominated by bracken fern Pteridium for long periods. Although forest regeneration bracken‐dominated is mainly hindered dispersal limitation, little known about role seed‐disperser communities slow succession. Our objective was to unravel differences properties between forests assess their limitation foster ecological...
Tropical forests are being reduced by human activities. The use of fire for agricultural expansion generates areas dominated the bracken fern Pteridium , where forest regeneration is slow. This may be caused seed limitation, especially animal‐dispersed seeds, due to absence dispersers from in deforested areas, calling restoration strategies assist regeneration. We installed bird perches and artificial bat roosts evaluate their effect on density, species richness, composition seeds seedlings...
Introduction Tropical montane forests are diverse ecosystems increasingly threatened by land-use change and frequent uncontrolled fires caused humans. After these fires, affected areas often dominated ferns of the genus Pteridium (bracken), delaying rate forest regeneration. This study examined facilitative competitive roles bracken fronds litter on seedling establishment, recruitment success, growth after 36 months, extent to which effects depend seed size in early plant development...
PREMISE OF THE STUDY: Biological responses to climatic change usually leave imprints on the genetic diversity and structure of plants. Information current dominant tree species has facilitated our general understanding phylogeographical patterns. METHODS: Using amplified fragment length polymorphism (AFLPs), we compared 384 adults P. tarapacana with those seedlings across 32 forest sites spanning a latitudinal gradient 600 km occurring between 4100 m 5000 a.s.l. in Polylepis (Rosaceae), one...
Pragmatic methods to assess the status of biodiversity at multiple scales are required support conservation decision-making. At intersection several major biogeographic zones, Bolivia has extraordinary potential develop a monitoring strategy aligned with objectives Group on Earth Observations Biodiversity Observation Network (GEO BON). Bolivia, GEO Observer since 2005, is already working adequacy national earth observations towards Global System Systems (GEOSS). However, still an...
In this study, the phenology of queñua (Polylepis incarum, Rosaceae) was evaluated during an annual cycle in mesophytic puna La Paz. The species is endemic to Lake Titicaca basin. Like other genus Polylepis, P. incarum categorized as Endangered for Bolivia due anthropic activities firewood extraction and crop expansion. During one year (March 2015 - February 2016), we conducted monthly evaluations a woodland located community Kopacati, Copacabana department, Paz, Bolivia. objectives study...

Anemophilous species depend on wind for sexual reproduction. When plants do not receive enough pollen and/or has poor quality, they may experience limitation. This can reduce the production of fruits and seeds with negative consequences population dynamics. The self-compatibility system also plays an important role likelihood a suffering limitation as it determines if produce in absence compatible mates. Here, we studied breeding Andean anemophilous tree Polylepis incarum, critically...
<title>Abstract</title> The allelopathic effect of Pteridium ferns (hereafter bracken) is considered an important factor hindering forest recovery. We examined the effects bracken allelopathy on seed germination, seedling emergence, survival, and relative growth rate (RGR) two native tree species, Morella pubescens Vismia plicatifolia, in a tropical montane forest. Two potential sources, fronds litter, were considered, along with site age (using soils from young old bracken-dominated sites,...
Fire is one of the main causes fragmentation in tropical Andean forests. Fragmentation can influence plant reproductive phenology, which turn affects bird communities. In Bolivian Yungas, we investigated how seasonal availability fruits and flowers richness, abundance community composition forest edges adjacent bracken (Pteridium ferns) dominated areas. We captured birds with mist nets at eight sites during dry, transition wet seasons, recorded fruit flower through phenological observations...
