Technical Report No. Department Trends and spatial dynamics of large herbivores in Kajiado District book Resource Surveys and Remote Sensing, Nairobi, by: A large component of reproductive success is surviving to sexual maturity, hence juvenile survival can be a key determinant of lifetime fitness, and so variation in survival can dictate population.

Territorial or resting behaviour of large herbivores can cause strong local deposits of dung, in different places than where they graze. Additionally, dung beetles and other macrodetritivores can subsequently affect local nutrient budgets through post‐depositional re‐dispersion of dung and accompanying by: 7.

Fryxell's aim (Chapter 6) is to evaluate the current understanding of forage intake and patch selection by herbivores across temporal and spatial scales, where resource (food) heterogeneity is large.

species especially the large herbivore are driven by variability and seasonal patterns in rainfall and temperatures [4] [5] [6].

Parameters for climate analysis include; air temperature. East African ecosystems are characterized by the migrations of large herbivores that are highly vulnerable to the recent development of anthropogenic land use change.

The common hippopotamus Hippopotamus amphibius can significantly influence the dynamics of ecosystems and engender serious conflicts with people but, in Kenya, one of the species strongholds, it has been little studied or monitored.

Abstract. Many ecosystems in Kenya are undergoing severe alteration due to landuse changes and associated human impacts. In one such large ecosystem, the Athi-Kapiti plains to the south of the city of Nairobi (and including Nairobi National Park), relatively healthy populations and migrations of large herbivores have been maintained despite increasing concentrations of domestic stock, settled Author: Helen Wanjiru.

But they could not be more wrong. It addresses an issue of the utmost practical importance in the world today, yet does so on the basis of exciting new theory about how the world operates.

- Biodiversity Monitoring for large mammals – This project of counting large mammal species upon a driven transect has been ongoing since with a database of sightings on established transects being kept and trends monitored. The data collected is used to calculate density indices, encounter rates and abundance kilometric indices.

The spatial structuring of populations or communities is an important driver of their functioning and their influence on ecosystems. Identifying the (in)stability of the spatial structure of populations is a first step towards understanding the underlying causes of these structures.

Here we studied the relative importance of spatial vs. interannual variability in explaining the patterns of. This book brings together information on the contrasting characteristics, condition, present use and problems of the world's main natural grasslands.

Since grassland is commercialized through the grazing animal, particular attention is paid to the livestock production systems associated with each main type. Grazing resources are more than simply edible herbage: many other factors have to be.

Quantitative descriptions of animal species’ distributions at the ecosystem level are rare. In this study we used marked spatial point pattern analysis to characterize herd spatial distributions of several species comprising a savanna large herbivore community in Laikipia, central by: 8.

A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant.

Introduction. Drought refers to a prolonged rainfall shortage and its impact on climate, hydrology, ecology and agriculture [1–3].Rain-fed farmers and pastoralists in the rangelands that span a quarter of the earth’s land surface are especially vulnerable to food shortages caused by drought [].Over the last century extreme famines caused by droughts have declined around the world as Cited by: Dynamics, Stability and Resilience of Inner Mongolian Grazing Ecosystems.
