Some neotropical rainforests rarely go a month during the year …

China has a long history of both using and managing fire use while still regularly forced to fight forest fires. My approach seeks to generate historical insights that explain how the wildfire paradox developed over the past 150 years in northeastern and southwestern China. To explore these dynamics, I use the concepts of “panarchy” and …The use of camera-derived vegetation indices in association with leaf demography-ontogeny models has been recently applied in the Amazon forest to investigate ecosystem-scale photosynthetic seasonality (Wu et al., 2016). However, there is still little focus on the species level analysis and on grasslands, mountains and other tropical vegetation.The subdivision into dry and wet ecozones within the tropics is a rough concept, which can be combined with the thermal periodicity given by the scheme in Fig. 1 (boxes of the upper right and left half). A comparative analysis of optimum plant growth phases for selected latitudes at the western half of continents shows existential differences.The purpose of this paper is to explore the relationship between modern pollen rain and vegetation in tropical China (woodlands on Hainan Island) and test for the first time the applicability of the available ERV sub-models and pollen dispersal models in this region to estimate RPPs for major plant taxa characteristic of such environments. 2.Sep 29, 2023 · Tropical rainforests, which worldwide make up one of Earth’s largest biomes (major life zones), are dominated by broad-leaved trees that form a dense upper canopy (layer of foliage) and contain a diverse array of vegetation and other life. Burning releases nutrients locked up in vegetation and produces a layer of nutrient-rich material above the otherwise poor soil. The cleared area is quickly planted and supports vigorous growth for a few years, after which the nutrient stock is depleted and large amounts of fertilizer are required to keep the operation viable. ...

Using this approach we identified that the overall vegetation condition of the Wet Tropics in the period 2003–2007 was ‘good’, but at a finer scale five of the bioregions nine subregions had ‘moderate’ condition, and only four had ‘good’ condition. The primary threat contributing to the ‘moderate’ condition was vegetation fragmentation due to …Rafflesia Arnoldii: the world’s biggest flower. One of the most amazing plants in the tropical rainforest is the Rafflesia arnoldii. It is only found in the rainforests of Borneo and Sumatra, and is the world’s largest flower. It gives of a smell like rotting flesh, which is why it is also known as the ‘ Corpse Flower ’.Sep 9, 2020 · It is important now to turn to a consideration of how well known vascular plants are in each of the three tropical regions we have analyzed [Table 2 (1–3, 7, 23, 24) and Fig. 2]. On average, 173 newly described species have been added to the flora of the Afrotropical Region each year since 2008, with 54 of these from Madagascar [Table 2 (1, 7)]. Previous efforts to estimate global tree cover potential have scaled existing vegetation estimates to the biome or ecoregion levels to provide coarse approximations of global forest degradation (6, 7).However, quantitatively evaluating which environments could support trees requires that we build models using direct measurements of tree cover …These forests represent the closest living remnant of the vegetation type from which all of Australia's unique vegetation developed.

Grasslands are vast and flat areas covered with different types of grass.Grasslands support a variety of species. Vegetation on the African savannas, for example, feeds animals including zebras, wildebeest, gazelles, and giraffes. On temperate grasslands, you might find prairie dogs, badgers, coyotes, swift foxes, and a variety of birds. There can be up to 25 species of large plant-eaters in a given grassland ...The landscape now included tropical deciduous forests, in which trees dropped their leaves in response to drought. During these periods, sunlight passed through the leafless canopy and heated and dried the surface of the ground. Many new species of plants and animals evolved, adapting to these new heat and moisture regimes.In tropical regions, intense fires associated with droughts can facilitate large-scale grass invasion in tropical forests, prompting the suggestion that such triggers could cause significant portions of the Amazon Forest to be displaced by grass-dominated vegetation (Silvério et al. 2013).

The vegetation can be grouped into two broad categories: the tropical-evergreen forests of the equatorial lowlands and the open type of tropical-deciduous, or “ monsoon,” forests in areas of seasonal drought. The evergreen forests are characterized by multiple stories of vegetation, consisting of a variety of trees and plants.

The equatorial vegetation comprises a multitude of evergreen trees that yield tropical hardwood, e.g. mahogany, ebony, greenheart, cabinet woods and dyewoods. There are smaller palm trees, climbing plants like the lianas or rattan which may be hundreds of feet long and epiphytic and parasitic plants that live on other plants.

On temperate grasslands, you might find prairie dogs, badgers, coyotes, swift foxes, and a variety of birds. There can be up to 25 species of large plant-eaters in a given grassland ...Abstract. The absence of a cold season results in plant activities in the tropics being limited by lack of water rather than by low temperatures. The distribution of natural vegetation types in the tropics is thus mainly determined by the seasonal distribution of rainfall. The effects on plants of the excessively high temperatures found in some ... We assessed data from 11 experiments examining the effects of the timing and/or frequency of fire on tropical forest and/or savanna vegetation structure over one decade or more. The initial ‘control treatment’ in many such cases consisted of previously cleared land.
