Birds as Bioindicators of Pollution in Aquatic and Terrestrial Environments [PDF]

, 2012
[eng] Birds have been widely used as bioindicators. In this study we face the use of birds as bioindicators of metal pollution in two different scenarios of contamination: one that takes place in an aquatic environment, the Ebro river basin, and a second

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

A bumblefoot outbreak and fatal septicemia in captive aquatic birds in Brazil Surto de esparavão e septicemia fatal em aves aquáticas cativas no Brasil

Ciência Rural, 2009
A bumblefoot outbreak with different prognosis according to host species was studied in captive aquatic avian species. Six wood ducks (Aix sponsa), three scarlet-ibis (Eudocimus ruber), two black-swans (Cygnus atratus), five white-faced ducks ...

Experimental infection of aquatic bird bornavirus in Muscovy ducks

Scientific Reports, 2022
AbstractAquatic bird bornavirus (ABBV-1), an avian bornavirus, has been reported in wild waterfowl from North America and Europe that presented with neurological signs and inflammation of the central and peripheral nervous systems. The potential of ABBV-1to infect and cause lesions in commercial waterfowl species is unknown.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

CONTRIBUTION TO THE KNOWLEDGE OF THE AVIFAUNA IN MARIA LIZAMBA AND ASSOCIATED BODIES OF WATER

Tropical and Subtropical Agroecosystems, 2011
The state of Veracruz, Mexico has many water bodies which are used by both men and birds. This study surveyed the avifauna of the lagoons Maria Lizamba, la Piedra, and small sections of the rivers Camaron and Estanzuela in Tierra Blanca, Veracruz. During

Quality versus quantity: response of riparian bird communities to aquatic insect emergence in agro-ecosystems

Frontiers in Sustainable Food Systems
In many agricultural landscapes where field drainage is required to enhance crop production, agricultural drainage ditches, and their associated banks and hedgerows can support riparian biodiversity, including bird communities.

Dental crown morphological variation and heterodonty in carcharhiniform sharks

The Anatomical Record, EarlyView.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

Myoglobin oxygen affinity in aquatic and terrestrial birds and mammals [PDF]

Journal of Experimental Biology, 2015
Myoglobin (Mb) is an oxygen binding protein found in vertebrate skeletal muscle where it facilitates intracellular transport and storage of oxygen. This protein has evolved to suit unique physiological needs in the muscle of diving vertebrates that express Mb at much greater concentrations than their terrestrial counterparts.

Ecology, impacts and management of pest birds [PDF]

, 2012
Pests can impact significantly upon the economy, the environment and on human and animal health. However, for pest birds there are surprisingly few studies of these impacts and how to reduce them. The aim of this thesis is to advance our understanding of
