Demographic and potential biological removal models identify raptor species sensitive to current and future wind energy

Ecosphere, 2021
A central challenge in applied ecology is understanding the effect of anthropogenic fatalities on wildlife populations and predicting which populations may be particularly vulnerable and in greatest need of management attention.

First nesting record of Turkey Vulture (Cathartes aura) in El Salvador

Huitzil, 2019
Despite the Turkey Vulture (Cathartes aura) being one of the most abundant scavengers on the American continent, details of their reproductive biology remain unknown in some countries.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

The Case of the Missing Green Iguana Predators: Reviews of Ecological Literature Should Go Beyond Google Scholar

The Bulletin of the Ecological Society of America, EarlyView.
Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.

Non-leucistic aberrations in the plumage of birds from Nayarit, Mexico

Huitzil, 2018
Abnormalities in the plumage are caused by multiple environmental and genetic factors. Plumage aberrations have been reported in Mexico, but all have been classified as leucistic (white color due to a recessive gene).

On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

Mathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.

Applying computer vision to accelerate monitoring and analysis of bird incubation behaviors: a case study using common eider nest camera footage

Remote Sensing in Ecology and Conservation, EarlyView.
Visualization of the pipeline is divided into two primary segments: automated (i.e., the user adapts the code directly to build a custom computer vision model) and human‐in‐the‐loop (i.e., the user manually evaluates the output of the model). In step 1, raw imagery data are selected for training and testing datasets; ideally, these datasets are ...

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

Wildlife Biology, EarlyView.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

Dynamic evolution of olfactory receptor genes in the Turkey Vulture and Black Vulture

Avian Research
Olfactory receptors (ORs), the largest vertebrate multigene family, exhibit wide copy number variation among taxa, ranging from ∼100 to 4000. The ecological importance of smell has been suggested to positively correlate with OR gene number, though debate

Protective role of the vulture facial skin and gut microbiomes aid adaptation to scavenging

Acta Veterinaria Scandinavica, 2018
Background Vultures have adapted the remarkable ability to feed on carcasses that may contain microorganisms that would be pathogenic to most other animals.
