ABSTRACT Identifying how limited resources, such as nutrients, are allocated across plant organs can provide new insights into ecophysiological strategies, well ecosystem nutrient cycles. Plants may allocate different nutrients within a specific organ or the same among organs. In this study, we explored allocation strategies of nitrogen (N) and phosphorus (P) in leaves, stems, roots nine dominant tree species secondary tropical dry forests using scaling analysis. The results showing that N P...
Phosphorus (P) plays a fundamental role in the physiology and biochemistry of all living things. Recent evidence indicates that organisms oceans can break down use P forms different oxidation states (e.g., +5, +3, +1, -3); however, information is lacking for from soil sediment. The Cuatro Ciénegas Basin (CCB), Mexico, an oligotrophic ecosystem with acute limitation, providing great opportunity to assess various strategies bacteria sediment obtain P. We measured activities exoenzymes involved...
ABSTRACT Aim To assess the hypothesis that free‐living prokaryotes show a pattern of ‘no biogeography’ by examining scaling soil prokaryotic diversity and comparing it with other groups’ biogeographical patterns. Location Two sites in tropical deciduous forest Chamela, Jalisco, on western coast Mexico. Methods We examined distribution two 8 × m quadrats divided such manner we could sample at four spatial scales. Restriction fragment length polymorphisms 16S rRNA genes were used to define...
The OMEGA/Mars Express hyperspectral imager identified gypsum at several sites on Mars in 2005. These minerals constitute a direct record of past aqueous activity and are important with regard to the search extraterrestrial life. Gale Crater was chosen as Science Laboratory Curiosity's landing site because it is rich gypsum, some desert soils Cuatro Ciénegas Basin (CCB) (Chihuahuan Desert, Mexico). CCB, which overlain by minimal carbonate deposits, product magmatic that occurred under Tethys...
The Cuatro Ciénegas Basin (CCB) is an oasis in the desert of Mexico characterized by low phosphorus availability and its great diversity microbial mats. We compared metagenomes two aquatic mats from CCB with different nutrient limitations. observed that red mat was P-limited dominated Pseudomonas, while green N-limited had higher species richness, Proteobacteria Cyanobacteria as most abundant phyla. From their gene content, we deduced both were very metabolically diverse despite use...
Patterns of genomic divergence between hybridizing taxa can be heterogeneous along the genome. Both differential introgression and local adaptation may contribute to this pattern. Here, we analysed two teosinte subspecies, Zea mays ssp. parviglumis mexicana, test whether their has occurred in face gene flow infer which environmental variables have been important drivers ecological differentiation. We generated 9,780 DArTseqTM SNPs for 47 populations, used an additional data set containing...
The rapid expansion of avocado cultivation in Michoacán, Mexico, is one the drivers deforestation. We assessed degree fragmentation and functional connectivity remaining temperate forest within Avocado Belt prioritized patches that contribute most to using a network-based approach modelling different seed pollen dispersal scenarios, including two types patch attributes (size conservation). As landscape transformation region ongoing, we updated land-use land-cover maps through supervised...
Abstract. With Earth's tipping points being approached and already exceeded, human-driven disruptions of carbon (C), nitrogen (N), phosphorus (P) cycles are forcing Earth’s biogeochemical systems toward irreversible collapse. Potential functional extinction key regulatory processes—such as carbonate precipitation, denitrification, burial, methane oxidation—could lead to cascading failures, spread beyond domains further contribute destabilize planetary homeostasis. This study examines...
Human activities have led to an increased influx of carbon into lakes due changes in land use that result higher erosion rates, eutrophication, and the introduction organic matter. This, turn, causes greater exports accumulation sediments. In our study, we estimated fluxes total particulate (FTPC), (FPOC), inorganic (FPIC) three with different trophic statuses. Two lakes, one eutrophic (Bosque Azul) mesotrophic (San José), are anthropically impacted zone plateau. contrast, oligotrophic lake...
