Responses of American black bears to spring resources
(Wiley, 2021-11)In temperate regions of the world, food resources are seasonally limited, which causes some wildlife species to seek out nutrient-rich resources to better meet their caloric needs. Animals that utilize high-quality resources ... -
Rub tree use and selection by American black bears and grizzly bears in northern Yellowstone National Park
(Ursus, 2022-06)Several of the world's bear species exhibit tree-rubbing behavior, which is thought to be a form of scent-marking communication. Many aspects of this behavior remain unexplored, including differences in rub tree selection ... -
A functional ecology framework for understanding and predicting animal responses to plant invasion
(Springer Science and Business Media LLC, 2022-05)Plant invasions can alter food resources and habitat conditions that structure animal communities. These effects are negative for many native animals, but neutral or even positive for others. Understanding why we see this ... -
Aplicación de sensores remotos para el análisis de cobertura vegetal y cuerpos de agua (Application of remote sensors for the analysis of vegetation cover and water bodies)
(SciELO Agencia Nacional de Investigacion y Desarrollo, 2020-12)This work analyzes remote sensors’ usefulness to analyze vegetation cover and water bodies in conservation and environmental studies. This research aims to determine satellite images’ applications in coverage studies and ... -
Global studies of cadmium in relation to Theobroma cacao: A bibliometric analysis from Scopus (1996 -2020)
(Universidad Nacional de Trujillo, 2021-12)The maximum cadmium tolerance standards were established by the European Union in 2014, for the importation of cocoa-based products, causing concern in the countries. Global studies on Theobroma cacao research related to ... -
Application of the Standardized Vegetation Index (SVI) and Google Earth Engine (GEE) for drought management in Peru
(Universidad Autonoma de Yucatan. Facultad de Medicina Veterinaria y Zootecnia, 2021-11)Background. The SVI (Standardized Vegetation Index) provides a relative comparison of the condition of the vegetation in different classifications for monitoring droughts. Objective. In this research, the SVI was used ... -
World historical mapping and potential distribution of Cinchona spp. in Peru as a contribution for its restoration and conservation
(Elsevier BV, 2022-12)Peru is a megadiverse country in neotropical flora and is home to an important genus of plants called Cinchona and commonly all its individual species are called Cinchona Tree (Cinchona spp.), which represents the national ... -
Variation in the Alcohol Components of Coffea arabica L. Wastewater Distillate Fermented Under Different Conditions
(Technoscience Publications, 2022-09)Coffee is the second-most consumed beverage in the world, and its high demand is covered by countries such as Peru, where the waste generated in production causes environmental pollution. We sought to determine the ... -
Geospatial Analysis of Soil Erosion including Precipitation Scenarios in a Conservation Area of the Amazon Region in Peru
(Hindawi Limited, 2021-09)The Tilacancha Private Conservation Area provides fresh water to the city of Chachapoyas. Therefore, the amount of soil lost in the year and under precipitation scenarios was determined. Individually, the values of the ... -
Warming temperatures affect meadow‐wide nectar resources, with implications for plant–pollinator communities
(Wiley, 2022-07)Nectar production may be a point of sensitivity that can help link primary and secondary trophic responses to climate shifts, and is therefore important to our understanding of ecosystem responses. We evaluated the nectar ... -
Earlier spring snowmelt drives arrowleaf balsamroot phenology in montane meadows
(Wiley, 2022-08)Climate change is shifting phenology globally, altering when and how species respond to environmental cues such as temperature and the timing of snowmelt. These shifts may result in phenological mismatches among interacting ... -
Heterogeneity in risk‐sensitive allocation of somatic reserves in a long‐lived mammal
(Wiley, 2022-07)Food quality and availability, when combined with energetic demands in seasonal environments, shape resource acquisition and allocation by animals and hold consequences for life-history strategies. In long-lived species ... -
The Importance of Phenology and Thermal Exposure to Early Life History Success of Nonnative Smallmouth Bass in the Yellowstone River
(Wiley, 2022-07)Knowledge of potential spread by introduced species is critical to effective management and conservation. The Smallmouth Bass Micropterus dolomieu is an example of a fish that has been introduced globally, often spreads ... -
Temporal correlations among demographic parameters are ubiquitous but highly variable across species
(Wiley, 2022-07)Temporal correlations among demographic parameters can strongly influence population dynamics. Our empirical knowledge, however, is very limited regarding the direction and the magnitude of these correlations and how they ... -
Responses of Flowering Plant and Butterfly Communities to Experimental Herbicide and Seeding Treatments for Native Grassland Restoration
(University of Wisconsin Press, 2021-08)Globally, grasslands are among the most degraded habitats, and within that category tallgrass prairies are especially threatened. To restore native species in tallgrass prairie, it is often necessary to concurrently remove ... -
Evaluating the importance of wolverine habitat predictors using a machine learning method
(Oxford University Press, 2021-12)In the conterminous United States, wolverines (Gulo gulo) occupy semi-isolated patches of subalpine habitats at naturally low densities. Determining how to model wolverine habitat, particularly across multiple scales, can ... -
Epidemiological differences between sexes affect management efficacy in simulated chronic wasting disease systems
(Wiley, 2022-02)Sex-based differences in physiology, behaviour and demography commonly result in differences in disease prevalence. However, sex differences in prevalence may reflect exposure rather than transmission, which could affect ... -
African wild dog movements show contrasting responses to long and short term risk of encountering lions: analysis using dynamic Brownian bridge movement models
(Springer Science and Business Media LLC, 2022-12)Background Prey depletion is a threat to the world’s large carnivores, and is likely to affect subordinate competitors within the large carnivore guild disproportionately. African lions limit African wild dog populations ... -
Quantifying fixed individual heterogeneity in demographic parameters: Performance of correlated random effects for Bernoulli variables
(Wiley, 2021-10)An increasing number of empirical studies aim to quantify individual variation in demographic parameters because these patterns are key for evolutionary and ecological processes. Advanced approaches to estimate individual ... -
Timing of Breeding Site Availability Across the North-American Arctic Partly Determines Spring Migration Schedule in a Long-Distance Neotropical Migrant
(Frontiers Media SA, 2021-10)Long-distance migrants are under strong selection to arrive on their breeding grounds at a time that maximizes fitness. Many arctic birds start nesting shortly after snow recedes from their breeding sites and timing of ...
