Protected Areas as Frontiers for Human MigrationÁreas Protegidas como Fronteras para la Migración Humana
submitted by harndag 1 day ago
Causes of human population growth near protected areas have been much debated. We conducted 821 interviews in 16 villages around Budongo Forest Reserve, Masindi district, Uganda, to explore the cau...
 


Effects of Flow Regimes Altered by Dams on Survival, Population Declines, and Range-Wide Losses of California River-Breeding FrogsEfecto del Régimen de Flujos Alterado por Presas sobre la Supervivencia, Declinación Poblacional y Pérdidas en el Rango de Di
submitted by koloemade 1 day ago
Widespread alteration of natural hydrologic patterns by large dams combined with peak demands for power and water delivery during summer months have resulted in frequent aseasonal flow pulses in ri...
 
Experimental Evidence for the Effects of Chronic Anthropogenic Noise on Abundance of Greater Sage-Grouse at LeksEvidencia Experimental de los Efectos de Ruido Antropogénico Crónico sobre la Abundancia de Centrocercus urophasianus en Leks
submitted by hazeltracee 1 day ago
Increasing evidence suggests that chronic noise from human activities negatively affects wild animals, but most studies have failed to separate the effects of chronic noise from confounding factors...
 
Human Perspectives and Conservation of Grizzly Bears in Banff National Park, Canada
submitted by krisss02 1 day ago
Some conservation initiatives provoke intense conflict among stakeholders. The need for action, the nature of the conservation measures, and the effects of these measures on human interests may be ...
 


A general theory of multimetric indices and their properties
submitted by eyoda86 2 days ago
Stewardship of biological and ecological resources requires the ability to make integrative assessments of ecological integrity. One of the emerging methods for making such integrative assessments ...
 
Multiple signals in the palmate newt: ornaments help when courting
submitted by JanAust 2 days ago
There is increasing evidence that female mate choice is often based on the assessment of multiple male traits, involving both morphology and behavior. We investigated female mate choice for multipl...
 
A case for quantile regression in behavioral ecology: getting more out of flight initiation distance data
submitted by PerryLoui 2 days ago
A central goal of behavioral ecology is to quantify and explain variation in behavior. While much previous work has focused on the differences in mean behavior across groups or treatments, we prese...
 
Female lizards discriminate between potential reproductive partners using multiple male traits when territory cues are absent
submitted by engpokaco 2 days ago
Female choice can powerfully influence the evolution of male phenotypes. In territorial species, it is challenging to determine the targets of female choice because male traits (e.g., behavior and ...
 
Litter reductions reveal a trade-off between offspring size and number in brown bears
submitted by FreJaxon 2 days ago
Experimental manipulations have revealed positive effects of litter reduction on offspring mass in small mammals, but little is known about this trade-off in large mammals. We examined the determin...
 
Social competition masculinizes the communication signals of female electric fish
submitted by bonniebon 2 days ago
Male intrasexual competition and female choice explain the evolution of male ornaments. Except in sex-role-reversed taxa, female ornaments have been regarded as an epiphenomenon of genetic correlat...
 
Predator-induced female behavior in the absence of male incubation feeding: an experimental study
submitted by 992096 2 days ago
Parental care plasticity is critical to understanding the ecological and evolutionary influence of nest predation on life history strategies. In birds, incubation imposes a trade-off between the re...
 
Correlated evolutionary changes in Drosophila female genitalia reduce the possible infection risk caused by male copulatory wounding
submitted by DilWes 2 days ago
Male and female genitalia often show corresponding morphologies indicating coevolutionary processes, but ongoing debate exists as to the driving mechanisms of such coevolution between the sexes. Us...
 
An automated system to control and manipulate the flight activity of captive birds
submitted by dena 2 days ago
Biologists have long been interested in the behavioural and physiological mechanisms that regulate flight. The manipulation of physical activity of birds under captive conditions, however, faces th...
 
Ecological bases of philopatry and cooperation in Ethiopian wolves
submitted by niilishg8 2 days ago
Ecological reasons for philopatry and cooperation are frequently invoked when kin selection is an insufficient explanation. The Ethiopian wolf (Canis simensis) is a specialised rodent hunter that f...
 
Consistent crustaceans: the identification of stable behavioural syndromes in hermit crabs
submitted by ConBre 2 days ago
Consistent individual variation in behaviour has been termed ‘animal personality’ and has been identified across a range of behavioural contexts including aggression, boldness in response to a ...
