Recruitment from seeds is among the most vulnerable stage for plants as global temperatures change. While germination means by which vast majority of world's flora regenerate naturally, a framework accurately predicting species are at greatest risk failure during environmental perturbation lacking. Taking physiological approach, we assess how one family, Cactaceae, may respond to temperature change based on thermal buffering capacity phenotype. We selected 55 cactus Americas, all...
Scrub mangrove forests, dominated by Rhizophora mangle L., are characterized high porewater salinity, which might compromise individual sap flow rates (SF) due to seasonal and diurnal microenvironmental variations. We tested the functional, anatomical, SF responses of 12 individuals variables such as solar radiation, photosynthetic photon flux, wind speed, evaporative demand, measured using an in situ weather station. Measurements were made dry rainy seasons Yucatan Peninsula, Granier heat...
Tropical wetlands are the largest natural source of methane (CH4) globally. While soils primary CH4 emitters, recent studies reveal that trees mediate soil-produced methane, highlighting potential underestimations in current and carbon budgets. In mangrove forests, contribution to local, regional, global emissions remains uncertain, despite their significant role as blue reservoirs. Mangrove species exhibit unique physiological morpho-anatomical adaptations—such extensive...
Abstract We assessed inter-seasonal dynamics of seed banks, dormancy and germination in three endemic Chihuahuan Desert succulent species, under simulated soil warming conditions. Hexagonal open top-chambers (OTCs) were used to increase temperature. Seeds Echinocactus platyacanthus (Cactaceae), Yucca filifera Agave striata (Asparagaceae) collected buried within outside OTCs. During the course one year, at end each season, batches exhumed test viability germination. Soil temperature OTCs was...
Abstract Human‐induced warming may increase the risk of local extinction for plant species with low tolerance elevated temperatures. The C hihuahuan desert harbors highest diversity globose cacti in world and most them are at extinction. Predictive models climate change indicate an summer temperature 1–2°C by 2030 this desert. Nevertheless, studies on vulnerability early development phases to future scarce. We assessed survival three threatened from under induced warming. Open‐top chambers (...
• Background and Aims One of the problems analysing cause–effect relationships growth environmental factors is that a single factor could be correlated with other ones directly influencing growth. attempt to understand tropical trees' integrating research about anatomical, physiological influence in order develop mathematical models. The relevance nature process model this as function environment.
Interest in invasive species has increased around the world over last several decades. In Mexico, studies on date as early 1939 and number of publications considerably recent However, to our knowledge, analysis information gaps research priorities is lacking. Therefore, it necessary identify knowledge order define future focus conservation efforts. We assessed current state biological invasions Mexico based existing literature. Our aim was which areas absent or insufficient should be...
Background Cacti establish mostly occurs under the canopy of nurse plants which provide a less stressful micro-environment, although mechanisms underlying this process are unknown. The impact combination light and watering treatments on Opuntia streptacantha (Cactaceae) seedlings was examined. Methods/Principal Findings Ecophysiological [titratable acidity, osmotic potential ('solute potential', Ψs), relative growth rate (RGR) their components (NAR, SLA, LWR)], anatomical (chloroplast...
Nama aff. stenophylla plants grow on mining waste abandoned 100 years ago, exposed to high concentrations of heavy metals. Accumulation metals in plant biomass has been related the phyto-accessible fractions these, so we assessed effect those different germination and development seedlings. The seed traits were characterized with optical scanning electron microscope. seeds for dormancy by pre-germinative treatments, percentage, tolerance index regarding metals, elongation seedlings under...
We describe strobilus and seed development in a Dioon edule (chamal, palma, dameu') population characterized by low seedling high adult tree density, order to improve conservation decisions for this endangered cycad species. Female strobili required 16-17 months male 4-5 develop. During period 80% female 100% were not damaged herbivores. The method of cone analysis used evaluate production pines was modified D. edule, providing actual yield individual compared potential yield, explaining...
Antecedentes y Objetivos: En México existen alrededor de 156 especies gimnospermas nativas pertenecientes a seis familias. Para el estado Oaxaca, se registran 45 sus habitantes poseen un sobresaliente conocimiento ancestral en uso tradicional este grupo taxonómico. El presente estudio contribuye al registro documentación del las evaluar la importancia familias botánicas como fuente recursos, analizar relaciones existentes entre los grupos étnicos riqueza útiles, así comparar registros...
A close relationship between leafing, flowering, fruiting and radial growth has been conjectured to occur in tropical subtropical rainforest trees. Radial stem growth, particular, associated with the activity of two secondary meristems, vascular cambium and, a lesser degree, phellogen. In trees may either virtually year-round, or it be restricted short season. Phellogen activities not correspond each other. environments, even evergreens demonstrate seasonal phenology leaf initiation,...
The environmental variability at local scale results in different physiognomic types of mangrove forest. However, this has never been considered studies genetic variability. This study analyzed the and morphological structure Rhizophora mangle regional scales Yucatan Peninsula. Thirteen populations (eight scrub five tall), located seven sites, were sampled, their relationship with availability phosphorus salinity analyzed. diversity estimated hierarchical levels nine microsatellites, also...
Morphological and structural changes among within leaves of Aphananthe monoica (Hemsley) Leroy, Pleuranthodendron lindenii (Turczaninov) Sleumer, Psychotria costivenia Grisebach were documented through canopy strata (<10, 1020, >20 m high) related to some environmental variables in a semi-evergreen Neotropical forest. The principal components analysis revealed that two explained 93% total variation. first component (76.4%) denoted leaf structure, whereas the second (16.6%) shape....
