Spatio-temporal composition of aquatic birds communityin Juluapan Lagoon, Colima, Mexican Central Pacific

Rev. biol. trop; 72 (1), 2024
Abstract Introduction: Aquatic birds (AB) are usually associated with wetlands, which provide refuge, food, and/or nesting sites for resident and migratory species. Despite their ecological importance, there is little knowledge on AB in some tropical environments, such as those found on the Colima coas...

Phylogenetic relationships of the Mangrove Hummingbird, "Amazilia" boucardi (Apodiformes: Trochilidae) of Costa Rica

Rev. biol. trop; 72 (1), 2024
Abstract Introduction: A recent revision of the generic classification of the Trochilidae based on DNA sequences revealed many inconsistencies with the current generic classification, largely based on plumage characters subject to homoplasy, especially in the Trochilini, the largest tribe. A thorough g...

Comparative Computed Tomographic Measurements of the Synsacrum in Some Birds

Int. j. morphol; 42 (4), 2024
SUMMARY: The Synsacrum is constructed of pelvic bones, sacral, lumbar vertebrae and some thoracic vertebrae, and it takes the form of a thin sheet of bone which is curled downwards at the sides. This study is designed to assess the morphometric specialization of the lumbosacral portion of the vertebral s...

Composition and spatio-temporal dynamics of aquatic bird community in humid areas of Alto Parana Atlantic Forest

Braz. j. biol; 84 (), 2024
Abstract The northwestern portion of the Upper Paraná Atlantic Forest ecoregion is one of the most disturbed and fragmented areas in the Atlantic Forest, and little is known about the local avifauna. In this study, we have described the composition and diversity of the aquatic avifauna of this region an...

Riverine forest as a significant habitat to harbor a wide range of bird species

Braz. j. biol; 84 (), 2024
Riverine forests are unique and highly significant ecosystems that are globally important for diverse and threatened avian species. Apart from being a cradle of life, it also serves as a gene pool that harbors a variety of flora and fauna species (repeated below). Despite the fact, this fragile ecosystem...

Sublethal toxicity of carbofuran in cattle egret (Bubulcus ibis coromandus): hematological, biochemical, and histopathological alterations

Braz. j. biol; 84 (), 2024
Abstract This study was aimed to investigate Carbofuran (CF)-induced pathological changes in cattle egret. Two hundred cattle egrets were reared and equally divided into four groups and given different CF concentrations (0.03 mg/L, 0.02 mg/L, 0.01 mg/L and 0 mg/L (control group)). Hematology, serum bioch...

Invertebrate dispersal by waterbird species in neotropical wetlands

Braz. j. biol; 84 (), 2024
Abstract Endozoochory by waterbirds is particularly relevant to the dispersal of non-flying aquatic invertebrates. This ecological function exercised by birds has been demonstrated in different biogeographical regions, but there are no studies for the neotropical region. In this work, we identified propa...

Blood parasites (Kinetoplastida: Trypanosomatidae) infecting birds in the Brazilian Amazon

Rev. biol. trop; 71 (1), 2023
Abstract Introduction: Trypanosomes are hemoparasites that can be observed circulating in the peripheral blood of birds. Parasitological studies in birds in their natural environment are neglected, but are important for research relating to transmission, maintenance of the biological cycle, and abundan...

Enteroparásitos en Columba livia, transmisibles al hombre en la población de Santa Rosa, estado Lara, Venezuela

Introducción . En el estado Lara no se había descrito la presencia de parásitos entéricos en Paloma Doméstica, por lo que, se seleccionó la población feral de Columba livia que frecuenta la plaza de Santa Rosa (lugar turístico/religioso) para investigar la presencia de taxones de importancia zoon...
