ABSTRACT Anthropogenic activities such as cattle grazing and forest clearing have led to the establishment of early successional grass layers in some native forests, which may inhibit or entirely prevent tree regeneration. We hypothesize that increased coverage reduces eliminates seedlings by limiting water availability seeds seedlings. This study aims evaluate impact cover on seedling survival under varying levels soil stress. conducted a field experiment using 36 experimental exclosures two northwest Patagonian valleys, representing regional gradient altitude, rainfall, canopy openness. Additionally, greenhouse was performed with pots, manipulating four three Results from both experiments showed similarities: field, likelihood finding live approximately 2.78 times higher areas without compared grass‐covered sites. In greenhouse, presence reduced final number established an average 43% across all irrigation levels, indicating significant competition. These findings suggest management practices promoting invasion could severely hinder regeneration forests not adapted large herbivore intensive grazing. Such situation be exacerbated regions suffering limitation growing season where climate change would intensify

Background and Aims: Seed germination studies are of great importance in conservation biology, restoration ecology, the development efficient propagation techniques. The use native shrub species activities is scarce owing to lack information on propagation, establishment, general management. For this study, we assess eight cloud forest by comparing seeds subjected a pre-germinative treatment (imbibition) without treatment, under two conditions: greenhouse chamber. We expect that constant temperature conditions exposure will germinate more quickly higher proportions than seeds, exposed variations any treatment. Methods: setup randomized experimental design consisting 10 petri dishes containing 30 per (i.e., imbibition or control) each condition chamber). recorded percentage, number days for initiation germination, t50. Key results: Our results showed an important difference response between both evaluated. optimal most were light 25°C provided chamber, as was associated with high rates germination. Conclusions: Understanding seed process can provide valuable insights into specific environmental required successful studied species. Furthermore, thorough understanding requirements guide effective techniques, well inform efforts allowing managers create strategies storage handling improve rates.

Abstract Restoration of tropical montane cloud forest (TMCF) landscapes is urgently required. Assisting the regeneration endangered and shade tolerant tree species essential for both recovery this vulnerable group ecological processes. However, there limited species‐specific information regarding performance under different disturbance conditions with which to implement effective interventions. We assessed seedlings in restoration plantings settings determined whether leaf mass area (LMA) dry content (LDMC)—functional traits typically associated resource capture or stress tolerance—could serve as predictors survival growth among species. Since conservative morphological can maximize survival, we expected higher LMA LDMC present survival. For a set eight native species, total 2,202 were planted four pastures, five secondary forests three subjected traditional selective logging, TMCF Eastern Mexico.

Choosing appropriate forest restoration interventions is challenging. Natural regeneration can rapidly facilitate recovery in many situations. However, barriers such as dispersal limitation and competition with non-native species require assisted approaches to plant community recovery. We used a study that has directly compared the outcomes of tropical wet across 11 replicate sites southern Costa Rica. Within this framework, we examined functional trajectories recruiting tree sapling communities gradient including low (natural regeneration), intermediate (applied nucleation), high (plantation) initial resource-investment, which remnant reference forest. collated leaf stem traits for comprised bulk saplings, then determined how community-weighted trait means diversity metrics changed over decade treatments. Results show nucleation, plantation) sped development more functionally diverse communities, than tripling richness (FRic) when natural regeneration. dispersion (i.e., range dominant species) was equivalent interventions, between 28 44% lower forest, indicating increases FRic under were driven by abundances (<10 individuals treatments). Recruits treatments also had 10–15% tougher, less-palatable leaves, leaves even tougher could be increasing herbivory pressure along interventions. tracking simple mask mechanistic understanding ecosystem elucidated taking trait-driven approach toward evaluating outcomes.
