Abstract Site fidelity after successful nesting and site shift nest predation (win–stay, lose–shift) is a well-documented adaptation to spatially heterogeneous temporally auto-correlated risk. However, even (win–shift) may become better tactic than (win–stay), if becomes more risky until the next opportunity, new low-risk sites regularly appear. Correspondingly, selecting non-used one previousl...

In hamsters and inbred mice, pheromone-containing chemosensory signals originating from the animal ́s own species (conspecific) and other species (heterospecific) produce differential patterns of immediate early gene (IEG = Fos/ FRAs) expression in the medial amygdala. In males of both species, conspecific stimuli, regardless of gender or putative function, activated neurons in both anterior and...

Plants can produce and release allelochemicals to interfere with the establishment growth of conspecific interspecific plants. Such allelopathy is an important mediator among plant species in natural managed ecosystems. This review focuses on grasslands forests. Allelopathy drives invasion, exacerbates grassland degradation contributes forest regeneration. Furthermore, autotoxicity (intraspecif...

There is a long history in neuroethology of investigating how communication signals influence the brain and behavior. It has become increasingly clear that brain areas associated with sensory processing are plastic in adults and that this plasticity is related to reproductive condition. However, the role of communication signal reception in adult auditory plasticity has received relatively litt...

Tree seedling dynamics underpin subsequent forest structure and diversity as different species/guilds respond variously to abiotic biotic stresses. Thus, understanding differential responses stresses helps us predict trajectories. Because forests vary in both environment species composition, generalisations across tropical are difficult. Afromontane important carbon stores, harbour high provide...

protons faster from the cytoplasmic than from the periplasmic side. The rate of proton abstraction must be reversed for NO intermediates, perhaps because a high pKa value prohibits protonation from a donor loaded from the cytoplasm (33, 34). How these intricate processes are spatially and temporally coordinated on an atomic scale remains open. The structure will, however, facilitate focused sit...
