Intent matters: how flow and forms of information impact collective navigation

The phenomenon of collective navigation has received considerable interest in recent years. A common line thinking, backed by theoretical studies, is that can improve efficiency through the 'many-wrongs' principle, whereby individual error reduced comparing headings neighbours. When takes place a flowing environment, each individual's trajectory influenced drift. Consequently, potential discrepancy emerges between an intended heading and its actual heading. In this study, we develop model to explore whether benefits are altered according form information transmitted Navigation based on found confer robust advantages across wide spectrum flows, via both marked improvement migration times capacity for group overcome flows unnavigable solitary individuals. far less effective, only offering under highly favourable currents. For many currents, sharing even lead journey exceed those navigators.

Brooding duration does not depend on cat predation risk but is related to weather and phenology in the wandering albatross (Diomedea exulans)

Ecology and Evolution, Journal Year: 2024, Volume and Issue: 14(9)

Parental investment increases offspring fitness at the expense of parent's ability to invest in other offspring. In many animal species, parents guard their after birth. The parental decision over duration this period is expected be triggered by associated costs and benefits for both parents. Here, we evaluated relevance several intrinsic environmental variables determining brooding wandering albatross (

ABSTRACT Ground-nesting birds such as Yellow-wattled Lapwing, Vanellus malabaricus (Boddaert, 1783) employ several nesting and behavioral strategies to mitigate nest predation, which greatly influences their reproductive success survival. Yet the breeding ecology of Lapwing has received relatively little research attention despite species’ widespread presence in Indian subcontinent. The objective this study was investigate significance impact two visual concealment commonly utilized by open ground-nesting birds: through vegetative characteristics camouflage using model organism. We also assessed nest-site selection Lapwings relation vegetation cover food availability, well choice substrate sampling, quadrat digital image analysis techniques. found that variation hatching could not be attributed analyzed mechanisms (disruptive markings pattern complexity matching). Furthermore, pairs exhibited a preference for areas with high low availability while selecting sites. showed species might exhibit an active substrates. It is important note conducted during single season Lapwings, further temporal replicates are necessary validate establish findings over long term.

Interspecific relationships in a suboptimal habitat, an unexpected ally for the survival of the threatened Tenerife speckled lizard (Gallotia intermedia)

Abstract Anthropogenic-driven environmental changes are pushing species to the limits of their habitats. More often restricted relic or suboptimal habitats that present minimum requirements sustain populations. In this scenario accelerated change and biodiversity loss, is fundamental understand why can survive in such conditions. We conduct an isotopic trophic analysis along with a behavioural experiment show how novel ecological interactions allow endangered maintain stable populations Tenerife speckled lizard ( Gallotia intermedia ), critically endemic reptile from Island (Canary Islands), thanks its yellow-legged gull Larus michahellis ) colony.
