COMPARISON OF COASTAL DUNE SCRUB IN ISRAEL AND CALIFORNIA: PHYSIOGNOMY, ASSOCIATION PATTERNS, SPECIES RICHNESS, PHYTOGEOGRAPHY

ABSTRACT Coastal dune scrub near Caesarea, Israel was quantitatively described from quadrats placed in 10 sites, ranging from pioneer to near-climax communities. Sampling intensity was greatest in a mixed shrub community (Artemisia monosperma, Helianthemum stipulation, Retama raetam) characteristic of stabilized dunes in the study area. Artemisia canopy had much less effect on the distribution of understory species than Retama and Helianthemum canopies. The sampled flora of 131 taxa was dominated by Leguminosae, Gramineae, and Compositae. About 45% of the flora had Mediterranean affinities, 17% coastal (mostly endemic to Israel), and 16% desert. California dune scrub from Point Reyes and Vandenberg areas was also sampled. The two sites are climatically similar to Caesarea, but both experience summer fog which lowers summer temperatures below those at Caesarea. Climax scrub was dominated by Lupinus arboreus and Haplopappus ericoides at Point Reyes, by H. ericoides associated with L. chamissonis, Core- thro...

Uma espécie nova de Surazomus (Arachnida, Schizomida) da Amazônia Oriental Brasileira

Surazomus paitit sp. nov. is described from the Caxiuana National Forest, State of Para, Brazil. The new species resembles S. manaus Cokendolpher & Reddell, 2000 and S. arboreus Cokendolpher & Reddell, 2000 due to the shape of the male flagellum (with three projections on the posterior region and two dorsal depressions arranged in a row); it differs from them by the presence of two spurs on the pedipalpal femur (instead of a single one in S. arboreus and none in S. manaus ), and by the male flagellum with slightly convergent sides posteriad (instead of parallel sides in S. manaus ).

Diversidad y caracterización florística de la vegetación en la zona de captación de aguas de la microcuenca El Tigre-Norcasia, Caldas

The diversity and cla. ssification of the floristic component behavior for five layers of the vegetation and tree community structure (DAP > 10cm), was evaluated in the high zone of the watershed El Tigre, Norcasia Caldas, by eight hazard sampling of a 1000 m 2 each one. The results of the classification defined the alliance Ingo codonanthae - Vismion guianensis and the associations Schefflero morototoni - Schizolo T bietum parahybi and Cariniano piriformydis Cordietum alliodorae. Moreover, meeting a community less development determine by Dendropanax arboreus - Euterpe precatoria. The diversity reported 37 families, 82 genera and 89 species, with the higher layer of larger richest. The community Dendropanax arboreus-Euterpe got the majors riches indexes, while the precatoria association Schefflero morototoni-Schizolobietum parahybi and the community Dendropanax arboreus-Euterpe precatoria, share the major diversity in proportional abundance.

Caracterización estructural, ordenación y dinámica de la vegetación en la zona de captación de aguas de la microcuenca El Tigre - municipio de Norcasia, Caldas

Structural behavior for five layers of the vegetation and tree community structure (DAP > 10cm), the classification and ordination of the floristic component and dynamic succession was evaluated in the high zone of a brook El Tigre, Norcasia Caldas, by eight hazard sampling of a 1000 m 2 each one. The results of the classification defined the alliance Ingo codonanthae - Vismion guianensis and the associations -Schefflero morototoni Schizolobietum parahybi and Cariniano piriformydis - Cordietum alliodorae. Moreover, meeting a community less development determine by Dendropanax arboreus - Euterpe precatoria. Three layers were difference with the tree lower layers more dominant. The specie obtained the larger IPF and IVI of the forest sinusie is facaranda copaia. Ocotea longifolia and Inga codonantha were dominant in the sociologic position. The IVIA was larger for Ocotea longifolia. The distributions in class to the forest sinusie define an inverse j. After of the ordination was definea a correlation between the hazards and the slope, arid a negative correlation between the slope and the basis saturation in the sames. The limited number of layers near to the dominion the ecological society heliofilos and hemisciofilos in the canopy and esciofilo in the low layers, determine an intermediate sucesional development of the vegetation.
