Indices of immune function used by ecologists are mostly unaffected by repeated freeze-thaw cycles and methodological deviations
Frontiers in Zoology - Tập 14 - Trang 1-8 - 2017
Over the past couple of decades, measuring immunological parameters has become widespread in studies of ecology and evolution. A combination of different immunological indices is useful for quantifying different parts of the immune system and comprehensively assessing immune function. Running multiple immune assays usually requires samples to be repeatedly thawed and re-frozen. There is some evide...... hiện toàn bộ
Hybridization in East African swarm-raiding army ants
Frontiers in Zoology - Tập 8 - Trang 1-14 - 2011
Hybridization can have complex effects on evolutionary dynamics in ants because of the combination of haplodiploid sex-determination and eusociality. While hybrid non-reproductive workers have been found in a range of species, examples of gene-flow via hybrid queens and males are rare. We studied hybridization in East African army ants (Dorylus subgenus Anomma) using morphology, mitochondrial DNA ...... hiện toàn bộ

Intra-cellular bacterial infections affect learning and memory capacities of an invertebrate
Frontiers in Zoology - Tập 12 - Trang 1-6 - 2015
How host manipulation by parasites evolves is fascinating but challenging evolutionary question remains. Many parasites share the capacity to manipulate host behavior increasing their transmission success. However, little is known about the learning and memory impact of parasites on their host. Wolbachia are widespread endosymbionts and infect most insect species. These bacteria are maternally tra...... hiện toàn bộ
Geckos cling best to, and prefer to use, rough surfaces
Frontiers in Zoology - Tập 17 - Trang 1-12 - 2020
Fitness is strongly related to locomotor performance, which can determine success in foraging, mating, and other critical activities. Locomotor performance on different substrates is likely to require different abilities, so we expect alignment between species’ locomotor performance and the habitats they use in nature. In addition, we expect behaviour to enhance performance, such that animals will...... hiện toàn bộ
Variation in rates of early development in Haliotis asinina generate competent larvae of different ages
Frontiers in Zoology - Tập 9 - Trang 1-9 - 2012
Inter-specific comparisons of metazoan developmental mechanisms have provided a wealth of data concerning the evolution of body form and the generation of morphological novelty. Conversely, studies of intra-specific variation in developmental programs are far fewer. Variation in the rate of development may be an advantage to the many marine invertebrates that posses a biphasic life cycle, where fi...... hiện toàn bộ
A protective nesting association with native species counteracts biotic resistance for the spread of an invasive parakeet from urban into rural habitats
Frontiers in Zoology - Tập 17 - Trang 1-13 - 2020
Non-native species are often introduced in cities, where they take advantage of microclimatic conditions, resources provided by humans, and competitor/predator release to establish and proliferate. However, native communities in the surrounding rural or natural areas usually halt their spread through biotic resistance, mainly via top-down regulative processes (predation pressure). Here, we show an...... hiện toàn bộ
Plasma oxidative stress in reproduction of two eusocial African mole-rat species, the naked mole-rat and the Damaraland mole-rat
Frontiers in Zoology - Tập 18 - Trang 1-9 - 2021
One of the most prominent life-history trade-offs involves the cost of reproduction. Oxidative stress has been proposed to be involved in this trade-off and has been associated with reduced life span. There is currently an unclear relationship between oxidative cost and the reproduction-longevity trade-off. The current study, using a non-lethal and minimally invasive (only a single blood sample an...... hiện toàn bộ
Tình trạng sinh sản và môi trường xã hội ảnh hưởng khác nhau đến sự biểu hiện của thụ thể steroid giới tính và mRNA aromatase trong não của chuột chũi Damaraland cái Dịch bởi AI
Frontiers in Zoology - Tập 11 - Trang 1-10 - 2014
Chuột chũi Damaraland (Fukomys damarensis) là một loài động vật có vú sống dưới lòng đất, có tính xã hội cao, trong đó sự phân bổ sinh sản cực đoan với một con cái (nữ hoàng) chiếm hữu việc sinh sản trong mỗi thuộc địa. Các con cái không sinh sản trong sự hiện diện của nữ hoàng bị ức chế sinh lý đến mức không rụng trứng. Sự chặn này được cho là do sự gián đoạn trong việc tiết hormone giải phóng go...... hiện toàn bộ

Audience effects in the Atlantic molly (Poecilia mexicana)–prudent male mate choice in response to perceived sperm competition risk?
Frontiers in Zoology - - 2009
Multidirectional interactions in social networks can have a profound effect on mate choice behavior; e.g., Poecilia mexicana males show weaker expression of mating preferences when being observed by a rival. This may be an adaptation to reduce sperm competition risk, which arises because commonly preferred female phenotypes will receive attention also from surrounding males, and/or because other m...... hiện toàn bộ
