Using satellite-derived MODIS NDVI data and near-surface remote sensing data from PhenoCam, the study shows a significant delay in leaf flushing (7 days/decade) and advancement of leaf fall (13 days/decade) in tropical semi-evergreen forests, which experience a shortened length of seasons by 17 days/ decade. However, the dry deciduous and thorn forests show an increasing season length of 7 days/decade. The climatic variables, such as minimum temperature and relative humidity, drive leaf flushing, while maximum temperature and PAR control leaf senescence in these forest types during a short period of preseason length.

Many species are considered tolerant of dormant season floods, but some experience reduced productivity and survival, which can influence competition and species composition. In lower elevation swamps of the Apalachicola River floodplain (Florida, USA), anthropogenically altered hydroperiod may predict observed species composition shifts from more flood-tolerant species, such as water tupelo (<em>Nyssa aquatica</em>) and pop ash (<em>Fraxinus caroliniana</em>) to less flood-tolerant competitors, such as water hickory (<em>Carya aquatica</em>) and overcup oak (<em>Quercus lyrata</em>).

We observed no differences in survival or rates of leaf flush among species after all treatment durations ranging between one and four months. Seven-month-old seedlings of these common competitors are similarly tolerant of dormant season flood events, when the Apalachicola floodplain is connected, and water conditions are aerobic.

An important innovation is the introduction of an auxetic structure, which allows for spatial expansion that is synchronous with the natural process of tree growth. Such structure also stretches along two axes as the trunk thickens, which is the exact opposite of how conventional materials behave. Due to the use of a steel-wire base, the structure is sturdy and durable with a good protective effect. On the other hand, the cellular pattern results in spring properties, which contribute to a moderate and constant surface pressure on the tree bark.

We surveyed woody plants across 120 plots in 15 remnant forest patches, examining five seed traits and their modes of dispersal. Results reveal that shrubs in such forests possess smaller seeds and lower yields, with a preponderance of seeds dispersed by birds rather than by wind or over short distances, unlike tree communities. Urbanization notably diminishes important seed traits like mass and length in trees, particularly for species with limited dispersal reach, while bird-dispersed species see an increase in quantity of seed but a reduction in seed mass. Meanwhile, seed yield rate in tree communities increased, but decreased in shrub communities. Structural equation modeling indicated that urbanization influences on seed traits are mediated by dispersal mechanisms and edge effects in trees, but only dispersal mechanisms in shrubs. The study concludes that the dispersal mode significantly mediates how seed functional traits of woody plants respond to urbanization in these forest remnants. Urban planning should therefore prioritize enhancing green corridors to facilitate natural seed dispersal and boost animal diversity, which could improve dispersal outcomes and contribute to maintaining and restoring plant diversity in urban forests.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"20 ","pages":"Article 100859"},"PeriodicalIF":2.7,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research examines the determinant factors that affect the farm households participation in CFM in the chilimo gaji forest, analyzing cross-sectional data from 365 randomly selected households. A double-hurdle model was employed for data analysis. The result demonstrate how demographic, socio-economic, institutional and biophysical factors impact both the decision to participate and the level of participation among farm households. Overall, the findings reveal that education, membership duration, access to training, access to forest resource, access to extension services, and perceptions of economic incentives are positively and significantly affect the participation decision and level of participation in CFM. The study shows disparities among farm households in participation levels, which can lead to unequal access to forest resource. Therefore, the study recommends that policymakers enhance households’ participation in CFM by improving training and capacity-building programs to overcome barriers to engagement, as well as implementing economic incentives and support mechanisms is crucial to motivate households to participate in CFM.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"20 ","pages":"Article 100855"},"PeriodicalIF":2.7,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
