Abstract Soil degradation by deforestation and introduction of exotic grasses is a grave consequence land‐use change in tropical regions during the last decades. restoration following natural succession (i.e., passive restoration) slow because low tree establishment. Introduction plantings human intervention active results promising strategy to accelerate forest soil recovery region. The present research was carried out explore properties after cattle exclusion grazing combined with native...

The Amazon ecosystem plays a vital role in global climate regulation and biodiversity conservation but faces escalating threats from deforestation degradation. resulting secondary forests (SFs) provide promising opportunity for Transformative Territorial Management, fostering restoration enhancing values. This study evaluated aboveground biomass (AGB), species diversity, forest structure, soil properties SFs of the Colombian along chronosequence, early to mature successional stages,...

Abstract: The effects of precipitation regime on the size soil carbon (C) pools were compared in mature tropical dry forests Yucatan Peninsula. Our study included three forest stands each, a site (potential evapotranspiration ratio = 3.2 mm −1 ; mean annual 537 mm), wetter (2.0 993 mm) and which water was comparatively less limiting (1.3 1086 mm). At each site, C dead fallen phytomass (includes leaves, flowers, fruits, small twigs deadwood debris) deposited litter layer roots organic matter...

Roadkill and landscape composition affect snakes at different spatial scales, depending on the functional trait value of species, which is reflected in diversity indices assemblage level. This study evaluated effect roads snakes' areas influence (250, 500, 1000, 2000 m buffer areas). We compared roadkill snake species with those assemblages inhabiting adjacent vegetation Orinoco region, Colombia. surveyed using transects road 13 landscapes along road. 16 metrics six land cover classes...

Succession in abandoned pastures the tropics can progress along different pathways, and changes biodiversity on local landscape scales, as well species turnover (β diversity), are still unclear. This study assessed role of secondary forests a plant reservoir or evidence pattern homogenization chronosequence two highly fragmented landscapes (hills mountains) Colombian Amazon. In each landscape, community composition, growth habits, richness accumulation, indicator identification, composition...

Increasing biodiversity in highly diverse plant communities can jointly increase ecosystem function and vulnerability. This paradox requires further attention. study analyzed the functional response of to above- below-ground parameters along chronosequence (degraded pastures (DP), early forests (EF), intermediate (IF), old-growth (OF)) two fragmented landscapes Colombian Amazon as an estimate level Three sets attributes were evaluated: (i) composition based on community-weighted mean (CWM)...

Abstract Key message Pre-germination requirements are not accurately predicted by seed traits of size and mass. However, small-seeded species show high germination slow early seedling growth rates. Deforestation in the tropics is one greatest biodiversity crises Anthropocene. In response, tropical countries such as Colombia have committed to restoring degraded lands reconnecting forest fragments. To contribute this mission, we evaluated how easy-to-measure functional rates (RGRs) for 11 tree...

This study evaluated aboveground biomass (AGB), species diversity, forest structure soil properties of the Colombian along chronosequence, early to mature successional stages, identify key...

Chronosequences provide apt space-for-time substitutions for the study of ecological succession. A thorough understanding succession can guide restoration efforts in critical areas, such as highly fragmented tropical landscapes susceptible to dispersal and seedling establishment limitations. We evaluate changes seed rain quantity quality through from traps set monthly September 2017 August 2018 18 plots (50 x 50 m) a humid forest chronosequence experiment lowland mountain physiographic...

Clear cutting exotic plantations favours natural regeneration processes in which seed banks may play an important role. In Andean high montane areas, after Pinus patula clear cutting, changes soil pH and litter lead to increased fauna flora biodiversity. However, the impactof these on remains unknown. The aims of present study were understand how bank richness, abundance, composition p. identify role above ground cover, cover variations. was conducted three areas with different post-clear...

Abstract Neotropical landscapes are often characterized as mosaics of actively grazed pastures and forest fragments at various stages succession. Restoring abandoned requires intervening with actions informed by local ecological Here we evaluate how litter production, a key component nutrient cycling in forests, varies between physiographic (hill lowland mountain), among stand age groups (early-secondary: 0–20 year, intermediate-secondary: 20–40 old-growth forests: > 40 year), response to...
