Full-text available
Identifying species' extinction risks and understanding their ecological associations are considered critical steps for achieving long-term conservation of biodiversity in the face of global changes. We evaluated the potential impact of global climate change (GCC) on the co-distribution patterns of 12 Mexican endemic hummingbirds and 118 plants the...

Full-text available
Studies of geographic variation of bird vocalizations facilitate the understanding of species' divergence and evolutionary histories, as vocal traits vary in response to different factors including the environment, morphology, culture, and inheritance. The Acorn Woodpecker (Melanerpes formicivorus) is a non-passerine species of the family Picidae,...
Article
Fruit size and shape are key traits that affect the interactions between plants and their seed dispersers within communities. Yet, the co-adaptive morphological links between fruits and bird seed dispersers within highly biodiverse Neotropical dry forests are still poorly understood. In this study, we evaluated the relationship between the morphome...
Article
Agriculture, cattle grazing, and human settlements negatively affect bird biodiversity, driving the loss of ecologically specialized species and favoring the dominance of generalists. Because ecological pressures define organisms’ success by acting on their intrinsic traits, biodiversity loss due to anthropization might cause directional trait shif...
Article
We documented a potential interspecies feeding event between 2 species of hummingbirds in southeastern Mexico in 2019. We used morphological and behavioral traits to identify the hummingbirds as an adult female White-bellied Emerald (Chlorestes candida) and a juvenile Rufous-tailed Hummingbird (Amazilia tzacatl). We ruled out the possibility of hyb...
Article
Comparing ecological networks along environmental gradients can enable a better understanding of the environmental filtering and coexistence mechanisms that determine community assembly. In the present study, we assessed hummingbird-plant network metrics at three sites along an altitudinal gradient in the Sierra Madre Occidental corresponding to tr...

The Military Macaw (Ara militaris) is an endangered species with scarce available information on its natural history. One of the main problems regarding its study has been the identification of individuals, which rapidly reach adult size and lack sexual dimorphism. Traditional marking techniques used to identify individuals require their capture; h...

Full-text available
Hummingbirds are one of the most threatened bird groups in the world. However, the extent to which global climate change (GCC) and habitat loss compromise their conservation status remains unclear. Herein, we proposed to: (1) assess how predicted GCC impacts the distribution of non-migrant hummingbirds according to their conservation status, degree...
Article
Full-text available
The Military Macaw (Ara militaris) faces a number of serious conservation threats. The use of genetic markers and assignment tests may help to identify the geographic origin of captive individuals and improve conservation and management programs. The purpose of this study was to identify the possible geographic origin of a captive individual using...
Article
Full-text available
The Short-crested Coquette (Lophornis brachylophus) is an endangered species endemic to Mexico. Currently, its distribution area is estimated at 53 km². Little to no information exists on its natural history, abundance, and distribution. The purpose of the present study is to describe its food resources, behavior, and interactions with plants and o...
Article
en Assessing the impact of working landscapes on biodiversity and defining locally contextualized management guidelines for productive activities are key for sustainability. Occupancy dynamics provide information about sites in the landscape that are either avoided or preferred by populations through the estimation of extinction and colonization pr...
Article
Full-text available
Background Plant-pollinator mutualistic networks show non-random structural properties that promote species coexistence. However, these networks show high variability in the interacting species and their connections. Mismatch between plant and pollinator attributes can prevent interactions, while trait matching can enable exclusive access, promotin...
Article
Full-text available
Background Despite the increasing knowledge of plant-pollinator interaction networks, the effects of human-induced disturbances on them have barely been studied. We analyzed whether land-use changes modified the structure and topology of plant-hummingbird interaction networks or promoted the integration of exotic plant species. Methods Fieldwork w...
Article
Full-text available
Cities act as biological filters on native biodiversity, selecting for traits allowing species to use urban resources, which may modify the phylogenetic structure and composition of biotic assemblages. Although many studies about urban filtering have included bird communities, few have focused on diverse and specialized groups, such as hummingbirds...
Article
Full-text available
The identification of mechanisms that have generated biodiversity is one of the major tasks in biogeography and evolutionary biology. Here, using a set of environmental variables and historical presence records, we assessed whether closely related allopatric lineages in the Arremon brunneinucha (Aves: Passerellidae) complex are either more ecologic...
Article
Also known as Boucard’s Tinamou, Slaty-breasted Tinamou is found only in Middle America, where its overall range extends from southeastern Mexico south to Costa Rica. This species is represented by two subspecies, which differ in overall coloration. It is recorded from sea level to at least 1800 m, and this tinamou is found in a variety of forest t...
Article
The northernmost representative of a large family of terrestrial birds, Thicket Tinamou occurs from northern Mexico south to southern Costa Rica. This species has two distinctive groups of populations. Along the Pacific lowlands of Mexico from Sinaloa to Guerrero is a subspecies that is gray below and whose male has an unbarred back. From Tamaulipa...
