Guía Aves Y Naturaleza 2017.Pdf
Zamora ciudad abierta al turismo de observación de la naturaleza La ciudad de Zamora y su término municipal cuenta con importantes enclaves de gran riqueza medio ambiental. Sin duda el río Duero, que la atraviesa de Este a Oeste, constituye uno de sus grandes recursos paisajísticos, pero también lo es el bosque de Valorio, dotado además de una considerable fuerza simbólica y sentimental para los zamoranos, así como los montes que ro- dean a la ciudad, tan cercanos que apenas terminan las últimas edificaciones se entra de lleno en la naturaleza. Esto permite disfrutar de la observación de las aves y otras muchas especies, no solo en las zonas ribereñas sino también en el espacio urbano, donde el ritmo tranquilo de la ciudad per- mite avistar numerosas especies que eligen para su hábitat la cercanía humana y conviven con nosotros sin dificultad. Con esta publicación, que incluye diversas rutas por la ciudad y alrededores, el Ayuntamiento de Zamora quiere abrir la puerta a esta interesante tendencia de la observación y estudio de los espacios naturales, tal como hace el turismo ornitológico y medioambiental, que además de promover los recursos locales abre también otras posibilidades relacionadas con la interpretación ambiental y la educación. Pero de manera especial nos permite acercarnos a los distintos espacios que ofrece la ciudad con de- tallismo y respeto, al tiempo que se divulga una parte importante de la avifauna y del patrimonio natural de Zamora. Francisco Guarido Alcalde de Zamora Búho chico (Asio otus) } La observación y la fotografía de las aves silvestres y de otros especies de nuestra fauna, como mamíferos, anfibios, reptiles, mariposas, libélulas, se han convertido en actividades que implican a un número muy considerable y creciente de personas. -
Frogs and Toads of Rhode Island
FROG & TOAD Chug-o-rum! Peep-peeep-peeep! Kraack-arrack! Frogs and toads thrive in the many ponds, forests , felds and open woodlands found on Audubon wildlife refuges. Spring and summer are great times to look and listen for them. Listed below are the common species found in Rhode Island. Bullfrog Northern Leopard Frog (Rana catesbeiana) (Rana pipiens) Bullfrogs are the largest frog in the United States Leopard frogs, as their name implies, are covered and have smooth, dull green to brown skin with in many, round black spots with lighter outlines. dark spots. Males have a yellow chin, and females Teir base color is usually brown or green but can have a white chin. Males make a deep echoing vary into yellow or blue. Tey have raised, golden croak “Chug-o-rum, Chug-o-rum” call in early ridges running down their back. Tey can be found summer. It can sound like a cow mooing, which in meadows and grasslands in the warmer months is why the word “bull” is in its name. Tey eat and near ponds and streams during breeding season. many insects, but will also eat fsh, rodents and Teir calls sound like a mix of “chucks” and “old small birds. creaky door” sounds. Green Frog Pickerel Frog (Rana clamitans) (Rana palustris) Green frogs greatly resemble bullfrogs, with a bright Nearly the twin of the leopard frog, pickerel green head and shoulders and hints of brown, blue or frogs are distinguished by their spots being black, but can be distinguished by the raised ridges square shaped rather than round and a bright down their backs. -
The Case of the Missing Frogs by Bryan Hamilton Why Are There No
The Case of the Missing Frogs By Bryan Hamilton Why are there no frogs in Great Basin National Park? Great Basin National Park seems like a perfect refuge for frogs, with plenty of water--ten perennial streams, hundreds of springs, and six alpine lakes, but apparently there are no amphibians. During 2002, an amphibian inventory was conducted within Great Basin National Park. Crews surveyed perennial streams, springs, and alpine lakes, but did not observe any adult amphibians, tadpoles, or egg masses. The reasons for this are unclear, but apparently frog distribution depends on more than just abundant water. Lack of suitable breeding habitat is a major limiting factor in amphibian distribution. Most amphibians require still or extremely slow moving water to lay their eggs in. High gradient streams in the Park do not provide appropriate breeding habitat. The hundreds of springs in the Park may provide this habitat, however, no amphibians were found at the dozens of springs surveyed this year. Isolation from source populations is another limiting factor. Streams leave the Park and then quickly disappear underground. Amphibian populations near the Park are not directly connected to these streams. Thus no corridors exist between the Park and nearby amphibian populations. One amphibian species that does not require aquatic corridors for migration is the Great Basin Spadefoot (Spea intermontana), commonly referred to as a "toad." Spadefoots are distinguished from "true toads" (members of the family Bufonidae) by a black wedge shaped spade on their hind feet, used for burrowing. Spadefoots move considerable distances over land during spring and summer rains, travelling to breeding sites. -
Protection of Cultural Landscapes Extremadura and Mallorca
Protection of Cultural Landscapes Extremadura and Mallorca Annual Report 2012/2013 - II Global Nature Fund Extremadura The Dehesas of the Extremadura in the Spanish southwest are over 5,000 years old, which makes them one of the oldest cultural landscapes in the world. The Dehesas, like the Middle European meadow orchards, are traditional agriculture- forest-meadow systems. This means that there are various ways of using the area and multiple ways the space offers people a livelihood. An almost natural form of this has developed in the Extremadura over time. Ancient, highly adapted farm animal breeds as well as extensive use of the stone and cork oak trees for firewood, and the proximity to natural habitats such as the Monfragüe national park make biodiversity on a scale usually only seen in tropical rainforests pos- sible. Such biodiversity is unheard of elsewhere in Europe. Characteristic of the area are the Iberian pigs that are famous for providing the “pata negra” ham. But only if they live mainly off acorns in the Dehesas. Extensive use continues to be the key to preserving this unique landscape southwest of Madrid where visitors can still experience pure nature. Even the untrained observer can spot Black Vultures, Imperial Eagles, owls, lynx and genets as well as White and Black Storks, many songbird species, several species of snakes such as the rare Montpellier snake and countless beetles, moths and grasshoppers. The GNF’s Spanish sister organization, Fundación Global Nature (FGN), has been working since 1993 to preserve and protect the Dehesas of the Extremadura. The FGN works in many areas such as environmental education, which takes place in their own environmental education center. -
Rhinella Marina) on Sanibel Island, FL
Possible Introduction Mechanisms, Movement Patterns, and Control Efforts of the Giant Toad (Rhinella marina) on Sanibel Island, FL Chris Lechowicz Director-Wildlife Habitat Management Program/Herpetologist Sanibel-Captiva Conservation Foundation Giant Toad (Rhinella marina) • Also called the cane toad, marine toad, Bufo toad, faux toad. • Previously Bufo marinus • Native to Central America, South America, Mexico, and south Texas. • A true toad (Family Bufonidae) belonging to a group of Neotropical toads (beaked toads = Rhinella). • Largest Bufonid toad (up to 5.8 lb), but not the largest Anuran (frog) in the world. Notable Facts • They have very large paired parotoid glands containing Bufotoxin that is oozed out when harassed. • This milky toxin has killed household pets (dogs, cats) and numerous wildlife species when ingested. • There has been documented human fatalities from “toad- licking” and ingestion. • Eggs/larvae are toxic to wildlife. • Highly nocturnal Prey and Predators • They consume invertebrates, small rodents, birds, amphibians, reptiles , and plants. • They will eat non-living prey (small dead animals, dog and food, feces). • The are preyed on in their natural range by caimans (C. latirostris), certain species of fish, Possums (Didelphis species), meat ants, banded cat-eyed snake (Leptodeira annulata), and some species of ibis. • They can lay up to ~30,000 eggs a year.

Project overview Title: Stepping ponds: enhancement of connectivity for amphibians in riverside gravel pits Contest: Spanish QLA Quarry name: Áridos Sanz S.A. Prize category: ☐ Education and Raising Awareness ☒ Habitat and Species Research ☒ Biodiversity Management ☐ Student Project ☒ Beyond Quarry Borders Abstract Amphibians are one of the most globally threatened taxa. In Europe, amphibians decline is mainly linked to habitat reduction and fragmentation. Gravel pits and other mining activities create floodable holes in the ground, that could be used for restoration porpoises. These cavities provide habitat opportunity for amphibians. The aim of this project was to evaluate the potential of the Áridos Sanz gravel pit to house amphibians and to increase landscape connectivity for this taxonomic group. 75 water bodies were characterized in Áridos Sanz gravel pit and its surroundings. They were characterized based on 27 attributes related to physical and hydrological conditions, water quality, vegetation, fauna and terrestrial uses and shelters. We defined a habitat suitability index based on species tolerance for each habitat attribute and its importance according to species requirements (for Pelophylax perezi, Pelobates cultripes, Pelodytes punctatus and Triturus marmoratus). Afterwards, we characterized habitat suitability and landscape connectivity for every species and proposed habitat improvement measurements which were evaluated in terms of their effectiveness. Results showed that gravel pit habitats are more suitable for more generalist species (as P. -
Green Heritage Spring 2010
GREENMONMOUTH COUNTY PARK HERITAGE SYSTEM The Newsletter of Monmouth County’s Open Space, Parks & Recreation Agency Vol. 44 No. 1 Spring 2010 The Park System has been hosting fishing contests since the 1960s. One of the earliest is shown at Shark River Park, right, 1968. Compare that to the annual Fishing Derby at Out- door Expo in Turkey Swamp Park, 2007, above. Monmouth County’s “Best Idea” Turns 50 The More Things Change, The More They Stay The Same n the last issue, we printed old photos that showed how county park facilities have changed over 50 years. Certain sites, like the beach at Seven Presidents Oceanfront Park for instance, saw the landscape utterly transformed. Not only were buildings relocated, docks (or Iwhat was left of them) removed, and new dunes built, but later a pavilion was added, a Skateplex was constructed and most recently, the playground was renovated—see below. Old photos of the parks also demonstrate the opposite trend: some things haven’t changed much at all in the last 50 years. People visit the parks and recreate in much the same ways now as they did in the 1960s (there are just many more people recreating).This may be due to the enduring nature of classic outdoor activities such as fishing, camping, hiking, and canoeing. And, with the possible exceptions of new technologies (cell phones with GPS, bird identification “apps,” fish-finders, etc.) and improvements to equipment , these activities look pretty much the same today as they ever did.
