Spontaneous Rhythmic and Tool‐Assisted Drumming Across Variable Tempo and Technique in a Captive Chimpanzee

open access: yesEthology, EarlyView.
A captive chimpanzee named Toon performed an unusual long‐lasting drumming session using different implements (e.g., limbs and tools) and techniques (e.g., drumstick‐on‐drum). He drummed faster with limbs than with tools and during the climax than the introduction of his pant‐hoot displays.

Estimation of Genetic Parameters for Wool Traits in Angora Rabbit

open access: yesAsian-Australasian Journal of Animal Sciences, 2011
Different genetic parameters for weaning weight and wool traits were estimated using restricted maximum likelihood (REML) in Angora rabbits. Total wool yield of first (I), second (II) and third (III) clips were taken as a separate trait under study. The records from more than 2,700 animals were analysed through fitting six animal models with various ...

Assessing soil and native high Andean grassland quality under grazing: A case study from the wet Puna of Peru

open access: yesGrassland Science, EarlyView.
Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.

A half century of monitoring reveals contrasting survival responses of Icelandic seabirds to climate and fisheries pressures

open access: yesIbis, EarlyView.
Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.
