In this paper, the authors measured distribution patterns of eight vertebrate species, using indices derived from transect counts of animals and their signs, and demonstrated highly significant relationships between animal distribution patterns and objective classification of landscape and seasons.
Abstract
SUMMARY wildlife communities was tested by measurement of distribution patterns of eight vertebrate species, using indices derived from transect counts of animals and their signs. Highly significant relationships between animal distribution patterns and objective classification of landscape and seasons were demonstrated. (2) Highest densities of animals occurred near borders of land systems. Methods used highlighted critical areas and yielded, rapidly and economically, information vital for sound management and establishment of national parks. (3) Dangers to the ecological viability of the Parque Nacional de Dofiana include overgrazing by non-indigenous species within the Park and development outside the Park of properties formerly acting as buffer zones.

Density‐Dependent Fecundity by Habitat Heterogeneity in an Increasing Population of Spanish Imperial Eagles

Miguel Ferrer, +1 more
- 01 Jan 1996 - 
TL;DR: An inverse relationship between fecundity and population size was found in this eagle population and was related to the year of pair establishment, being higher in recently occupied territories.

Causes and fitness consequences of natal dispersal in a population of black kites

TL;DR: Patterns of dispersal in this population of Black Kites are probably driven by intraspecific competition, and males that dispersed shorter distances showed higher lifetime reproductive success (LRS), while females that dispersed farther mated with more experienced males.

Ecology of the Mediterranean Annual-Type Pasture

R.C. Rossiter
- 01 Jan 1966 - 
TL;DR: This chapter discusses the Mediterranean annual-type pasture that has potential scope for marked and rapid seasonal changes in botanical composition and chemical composition, and the incorporation of deep-rooted perennials into the ecosystem might offer a solution.
