Night Heron

A method of assessing ecological risk to night heron, Nycticorax nycticorax, population persistence from dichlorodiphenyltrichloroethane exposure.

This paper first introduces a probabilistic method for quantitatively evaluating the effects of chemical pollutants in the environment on a wildlife population, which was applied to assess the ecological risk to night heron (Nycticorax nycticorax) population persistence from dichlorodiphenyltrichloroethane (DDE) exposure in Tai Lake, China. Intrinsic rate of population increase (r) calculated w...

Breeding Biology of the Night Heron Nycticorax Nycticorax in the South-west of Spain

The Night Heron Nycticorax nycticorax is widespread across the Palaearctic region though its population has decreased during the last century (Cramp & Simmons, 1977). In the Iberian Peninsula it has a threatened status (Blanco & González, 1992) and its reproduction is concentrated in no more than thirty colonies in the North, Northeast and Southwest (Palacios, 1997). Currently, population estim...

Status update on White-eared Night Heron Gorsachius magnificus in South China

The Project HERON

In the project HERON, we developed a framework for articulatory speech synthesis for European Portuguese. The system combines several modules, developed or adapted in the project. The Linguistic Processing model uses new syllabification and grapheme-to-phone modules developed in the project. The construction of the gestural scores is performed using an adapted version of TADA (TAsk Dynamic Appl...

A New Subfossil Night Heron and a New Genus for the Extinct Rail from Ascension Island, Central Tropical Atlantic Ocean

Ascension (Figs. 1, 2) is a recent volcanic island some 10 km in diameter lying at 07°57'S 14°22'W in the central tropical Atlantic Ocean 350 nautical miles south of the Equator. When discovered in 1501 it had a poor flora and terrestrial fauna, but many breeding seabirds presumably feeding along the equatorial current system (Bourne & Simmons 2001). The birds' destruction may have begun when B...
