Are all patches worth exploring? Foraging desert birds do not rely on environmental indicators of seed abundance at small scales

BMC Ecology, 2019
Background Consumers should show strong spatial preferences when foraging in environments where food availability is highly heterogeneous and predictable.

Osmoregulatory responses to dietary protein and water intake in the granivorous Zonotrichia capensis (Passerine, Emberizidae) Respuestas osmorregulatorias a la proteína dietaria y al consumo de agua en el granívoro Zonotrichia capensis (Paseriformes, Emberizidae)

Revista Chilena de Historia Natural, 2007
We studied the osmoregulatory responses of the granivore Zonotrichia capensis, acclimated to high- and low-protein diets as well as two levels of water intake. We tested whether Z. capensis has the ability to modify the proportion of nitrogenous waste in

Forty years of carabid beetle research in Europe – from taxonomy, biology, ecology and population studies to bioindication, habitat assessment and conservation

ZooKeys, 2011
‘Carabidologists do it all’ (Niemelä 1996a) is a phrase with which most European carabidologists are familiar. Indeed, during the last half a century, professional and amateur entomologists have contributed enormously to our ...

Scatter-hoarding of Cape Proteaceae nuts by rodents [PDF]

, 2002
Most large-seeded shrubs and trees from Mediterranean shrublands are either serotinous (canopy stored seeds) or myrmecochorous (ant-buried). It has been hypothesized that these traits evolved to prevent access to the seeds by rodents. Here we present the

Insect seed and cone predation reduces reproductive potential of treeline conifers across northern Canada

, 2022
<p><strong>Aim</strong>: Altitudinal and latitudinal treeline ecotones have not consistently responded to climate warming the in direction and/or magnitude as predicted by climate alone, suggesting that non-climatic mechanisms (e.g ...

Moderate wildfire severity favors seed removal by granivores in a Mexican pine forest

iForest - Biogeosciences and Forestry
Wildfires are critical to the ecological dynamics of communities in temperate forests. However, their frequency and severity have increased significantly in recent decades due to human activities, negatively affecting flora, fauna, and ecosystem ...

PHYLLOCAULIS GAYI (PULMONATA: SYSTELLOMMATOPHORA): A NEGLECTED GRANIVORE IN CHILEAN TEMPERATE FORESTS? PHYLLOCAULIS GAYI (PULMONATA: SYSTELLOMMATOPHORA): ¿UN GRANIVORO DESCONOCIDO EN LOS BOSQUES TEMPLADOS DE CHILE?

Gayana, 2003
Evidence is advanced suggesting that Phyllocaulis gayi, a large slug in the temperate forests of Chile, might be a significant but overlooked granivore. In a short-term experiment, up to 18% of seeds are preyed upon by P. gayi.

Spatial-scale dependencies in the predation of seeds by rodents [PDF]

, 1995
Summary 1. Previous studies have shown rates of seed predation in deciduous woodland to be high (on average 60%) and extremely variable in space and time. 2.
