An inversive meadow is a commutative ring with identity and a total multiplicative inverse operation satisfying 0 = 0. Previously, inversive meadows were shortly called meadows. In this paper, we introduce divisive meadows, which are inversive meadows with the multiplicative inverse operation replaced by a division operation. We introduce a translation from the terms over the signature of divis...

Anthropogenic disturbances in nature can be defined by energy and emergy terms. I studied four saline meadows with different protection status to see if they differ in species richness and plant biomass of halophytes and in the level of anthropogenic disturbance. The four studied meadows were located in the Kujawy region, the central part of Poland. The first study area was the reserve of halop...

The large predatory ant, Paraponera clavata, exerts measurable top-down effects in wet and moist Neotropical forests, and therefore its distribution has potential ecological implications. To determine how water affects the presence of this important predator, the ground nesting ecology of P. clavata was examined with respect to various habitat characteristics. Four hectares of disturbed Costa R...

Abstract Cymodocea nodosa , a typical marine angiosperm species in the Mediterranean Sea, hosts range of epiphytic algae. Epiphyte abundance varies at different spatial scales, yet epiphyte diversity and community composition are poorly understood. This study explores epiphytes on C. from two reference meadows (Thasos, Vrasidas) one anthropogenically stressed meadow (Nea Karvali) northern Aegea...

OBJECTIVE To analyze and evaluate the effects of humanized nursing combined with wet healing therapy to treat the stage II and III bedsores in hospitalized patients. PATIENTS AND METHODS From March 2013 to July 2014 we enrolled fifty patients with stage II and III bedsores. They were randomly divided into control group and experimental group, with 25 cases in each group. For the control group...

Physiol. 278: H951–H957, 2000.—We used the isolated-perfused rat lung model to study the influence of pulmonary ventilation and surfactant instillation on the development of postreperfusion lung microv...

Flexible conservation management, where measures (e.g., mowing of meadows, removing invasive species) are selected in each decision period depending on the current state of the ecological system, is generally perceived as superior to fixed management, where the same measure is applied in each decision period independent of the current state of the system. In past comparisons of fixed and flexib...

Effect of fertilizer applications and grazing exclusion on species composition and biomass in wet meadow restoration in eastern Washington. Fertilizer applications and grazing exclusion were used as restoration strategies in degraded wet meadows in eastern Washington to grow biomass in the root systems where it could not be grazed. We used a split-block design to test vegetation responses to si...
