We measured annual carbon flows to wood production, foliage production and total belowground carbon flux (the sum of root production, root respiration, and mycorrhizal production and respiration) from ages three to five years in clonal Eucalyptus plantations at four sites in Brazil to test if fertility, water availability and stand structure changed wood production and by what mechanism.
Using the pressure-state-response model as a framework, a series of indicators were identified and assessed, which were also used by the local population and grouped into landscape structure, soil fertility, water availability and quality, production system and extractive activities, economic and social performance, and institutions.
Scholars note that jewelry is uniquely important for its association with "all the things with which man is most concerned: money, power, religion and love". Engagement rings are both a means to and a symbol of ownership of female sexuality, visibly communicating fertility and availability status.
Productivity is a function of a sugar cane yield which depends on soil fertility, water availability and variety.
Adopting the assumption that a reduction in the opportunity costs of childbearing will result in higher fertility, childcare availability has frequently been hypothesized as having a positive influence on fertility (Becker 1991).
This favorable reproductive health and family planning law includes comprehensive measures such as the protection of legal ethics and quality of life; improvement of gender relations; accountability of public authorities, civil society, and local communities; fertility assistance; availability of contraceptives and quality services; and the decriminalization of reproductive health.
Self-fertility, the availability of several diploid accessions, and its intrinsic resistance to diverse biotic and abiotic stress conditions are additional attributes.
The deer time their fertility by light availability, not temperature.
Having this information at hand provides practitioners with useful information to manage sites specifically according to their characteristics (topography, soil, water availability, fertility, etc).
For example, savanna species are adapted to decreased soil fertility and water availability (Ruggiero et al. [2002]) and to regular fires (Moreira [2000]; Miranda et al. [2002]), factors that may lead to the local extinction of forest species.
