The effect of climate change on the duration of avian breeding seasons: a meta-analysis by Halupka, Lucyna, Halupka, Konrad

“…Many bird species are advancing the timing of their egg-laying in response to a warming climate. Little is known, however, of whether this advancement affects…”

Information flow in a network of dispersed signalers-receivers by Halupka, Konrad

“…I consider a stochastic model of multi-agent communication in regular network. The model describes how dispersed animals exchange information. Each agent can…”

Partial Nest Predation in an Altricial Bird Selects for the Accelerated Development of Young by Halupka, Konrad

“…In response to disturbance young of altricial open-nesting birds may leave the nest several days before the usual age for nest leaving. In Meadow Pipits Anthus…”

Incubation Feeding in Meadow Pipit Anthus pratensis Affects Female Time Budget by HALUPKA, K

“…Sixteen female Meadow Pipits were observed during the incubation period to test the hypothesis that incubation feeding by the male constitutes an important…”

Why Does the Frequency of Nest Parasitism by the Cuckoo Differ Considerably Between Two Populations of Warblers Living in the Same Habitat by Dyrcz, Andrzej, Halupka, Konrad

“…The rate of nest parasitism is a product of two interacting phenomena: host selection by cuckoos and defence by hosts. In our study area the rate of nest…”

The influence of parental behavior on vulnerability to nest predation in tropical thrushes of an Andean cloud forest by Halupka, Konrad, Greeney, Harold F.

“…The Skutch hypothesis predicts that parental activity around the nest may attract the attention of predators and thus, in the tropics where predation pressure…”

Vocal begging by nestlings and vulnerability to nest predation in Meadow Pipits Anthus pratensis; to what extent do predation costs of begging exist? by HALUPKA, KONRAD

“…Models of the evolution of parent‐offspring communication and of brood size assume that the noisy begging by the young is costly in terms of predation. The…”
