Breeding of black-winged stilt Himantopus himantopus in muddy sites of a wastewater treatment plant

open access: yesBiosystems Diversity, 2021
A stable group of birds has been formed at water treatment facilities. Sewage treatment sites are a well-known nesting place for long-legged waders. Black-winged stilts are included in the Bonn (Appendix II) and Berne (Appendix II) conventions, the AEWA ...

Nested information processing in the living world

open access: yesAnnals of the New York Academy of Sciences, 2021
AbstractLiving organisms create, copy, and make use of information, the content depending on the level of organization. In cells, a network of signal chain proteins regulates gene expression and other cell functions. Incoming information is encoded through signal reception, processed by the network, and decoded by the synthesis of new gene products and

Exploring the potential for cross-nesting structures in airport-choice analysis: A case-study of the Greater London area [PDF]

open access: yes, 2006
The analysis of air-passengers’ choices of departure airport in multi-airport regions is a crucial component of transportation planning in many large metropolitan areas, and has been the topic of an increasing number of studies over recent years. In this

A long-term decline in the abundance of endangered leatherback turtles, Dermochelys coriacea, at a foraging ground in the California Current Ecosystem

open access: yesGlobal Ecology and Conservation, 2020
Pacific leatherback turtles (Dermochelys coriacea) are critically endangered, and declines have been documented at multiple nesting sites throughout the Pacific. The western Pacific leatherback forages in temperate and tropical waters of the Indo-Pacific

Increased complexity of worker CHC profiles in Apis dorsata correlates with nesting ecology.

open access: yesPLoS ONE, 2022
Cuticular hydrocarbons (CHC) are known to serve as discrimination cues and will trigger defence behaviour in a plethora of eusocial insects. However, little is known how about nestmate recognition ability selects for CHC diversification. In this study we

Statistics of Merging Peaks of Random Gaussian Fluctuations: Skeleton Tree Formalism [PDF]

open access: yes, 1999
In order to study the statistics of the objects with hierarchical merging, we propose the skeleton tree formalism, which can analytically distinguish the episodic merging and the continuous accretion in the mass growth processes.

Using behavior indices and vital rates to determine the conservation impact of wildlife tourism: Guided sea turtle watch programs in Florida

open access: yesGlobal Ecology and Conservation, 2021
Recent rapid growth in wildlife tourism necessitates understanding its biologically-significant impacts on targeted species. To evaluate these effects, we studied how loggerhead sea turtles (Caretta caretta) responded to public sea turtle watch programs ...
