As an example, Eschweilera coriacea is often found on sandy, nutrient-poor soils within the Amazon basin.
-
Dispersal Limitations
The ability of a species to disperse its seeds and establish new populations limits its distribution. Large-seeded species, such as the Brazil nut (Bertholletia excelsa), often have restricted distributions due to their reliance on specific animal species for seed dispersal. Wind-dispersed species, in contrast, may exhibit broader distributions. The geographic isolation of certain areas can also limit species dispersal, leading to the evolution of unique regional floras.
-
Species Interactions
Competition, facilitation, and other species interactions influence distribution patterns. Competitive exclusion may prevent some species from occupying certain habitats, while facilitation, where one species creates conditions that benefit another, can promote co-occurrence. Herbivory and seed predation can also affect distribution patterns by limiting the survival and recruitment of specific species. For example, the presence of certain ant species can protect plants from herbivory, influencing their distribution.
-
Historical Events
Past climatic changes and geological events have shaped the current distribution. During glacial periods, the Amazon rainforest contracted, leading to fragmentation and the isolation of populations. These isolated populations may have diverged genetically, resulting in the formation of new species. The distribution of species also reflects past disturbances, such as fires and floods, which can create opportunities for colonization and succession.
These factors collectively determine the distribution patterns observed in the Amazon. By analyzing these patterns, scientists can gain insights into the ecological processes that shape the forest and develop more effective strategies for its conservation.

5. Threats
The long-term survival of many plant species within the Amazon rainforest is jeopardized by a range of interconnected threats, primarily driven by human activities. Deforestation, resulting from agricultural expansion, logging, and infrastructure development, directly reduces the area of available habitat. This habitat loss disproportionately impacts specialized species with limited dispersal capabilities or narrow ecological niches. For instance, selective logging, while seemingly less destructive than clear-cutting, can alter the forest structure and microclimate, negatively affecting shade-tolerant species and disrupting pollination and seed dispersal processes. The increased fragmentation of the landscape further isolates plant populations, reducing genetic diversity and increasing their vulnerability to local extinction. The increased forest fires in the Amazon, often deliberately set to clear land for agriculture, pose an immediate and catastrophic threat, destroying vast swaths of vegetation and releasing significant amounts of carbon into the atmosphere. The impact from these fires have a long term effect in species.
Climate change constitutes another significant threat, altering temperature and rainfall patterns, and increasing the frequency and intensity of extreme weather events. These changes can disrupt the phenology of plant species, affecting flowering, fruiting, and seed germination. Altered rainfall patterns, leading to prolonged droughts or increased flooding, can also exceed the physiological tolerances of certain species. The combined effects of deforestation and climate change create a synergistic threat, making plant species more vulnerable to pests, diseases, and invasive species. For example, droughts can weaken trees, making them more susceptible to insect infestations, such as those caused by bark beetles.
Addressing these threats requires integrated conservation strategies that combine protected area management, sustainable resource use, and climate change mitigation.
