Studies on habitat use have often helped explain observed variation in morphology, behavior, and reproductive characteristics among populations within a single species. Here we analyze morphological and ecological characteristics of individuals from the Sceloporus grammicus species complex from seven different localities (El Cerezo: CER, Pachuca: PAC, Huichapan: HUI, Emiliano Zapata: EZA, San Miguel Regla: SMR, La Mojonera: LMJ, and La Manzana: LMZ) in the state of Hidalgo, and one locality (Cahuacán) in the State of México...

Understanding of animal spatial behavior is essential for informed management decisions. In southern Africa, reintroduction of lions (Panthera leo) to small reserves (<1000 km(2) ) has increased in recent years but studies on their ranging behavior in these enclosed systems remain lacking. We applied Time Local Convex Hull (T-LoCoH) methods to study the home range establishment and utilization of 11 lions reintroduced to Dinokeng Game Reserve, South Africa, during 2011 through 2014. Lions established home ranges close to their release sites and during the following three years their home range sizes continued to increase, but in each individual case it remained smaller than half of the reserve area (< 70 km(2) )...

While there are numerous wildlife ecology studies in lowland areas of Nepal, there are no in-depth studies of the hilly Churia habitat even though it comprises 7,642 km(2) of potential wildlife habitat across the Terai Arc. We investigated tiger, leopard, and prey densities across this understudied habitat. Our camera trapping survey covered 536 km(2) of Churia and surrounding areas within Chitwan National Park (CNP). We used 161 trapping locations and accumulated 2,097 trap nights in a 60-day survey period during the winter season of 2010-2011...

Rodents with prevailing subterranean activity usually play an important role in the ecosystems of which they are a part due to the combined effect of herbivory and soil perturbation. This is also the case of the giant root-rat Tachyoryctes macrocephalus, Rüppell 1842, endemic to the Afroalpine ecosystem of the Bale Mountains, Ethiopia. We studied the impact of root-rats on various ecosystem features within a 3.5ha study locality dominated by Alchemilla pasture, which represents an optimal habitat for this species, in two periods of a year...

It is not well investigated that cultivated trees affect seeding regeneration of their wild relatives that share similar seed dispersers of animals. Here, we investigated the differences in seed fates of cultivated walnut (Juglans regia) and wild Manchurian walnut (J. mandshurica) trees under rodent predation and dispersal. J. regia seeds have higher nutritional value (large size, mass and kernel mass) and lower mechanical defensiveness (thin endocarp) than J. mandshurica seeds. We tracked seeds of J. regia and J...

Planarians are the ideal models for studying eye development with the simple eye structure and exceptionally rapid regeneration. Here, we observed the eye morphogenesis, photophobic behavior, spectral sensitivity, and expression pattern of Djopsin in planarian Dugesia japonica. The results showed that: (1) Djopsin encoding the putative protein belonged to rhabdomeric opsins group and displayed a high conservation during animal evolution; (2) planarians displayed diverse photophobic response to different visible wavelength and were more sensitive to the light blue (495 nm) and yellow (635 nm); (3) the morphogenesis and functional recovery of eyes were related to the expression pattern of Djopsin during head regeneration; (4) Djopsin gene plays a major role in functional recovery during eyes regeneration and visual system maintenance in adult planarians...

Integrative Zoology began in 2006 as a voice for the newly formed International Society of Zoologists. A decade later, it has clearly achieved this - and very much more. For it is now successfully placed within the top quartile of journals in zoological sciences. This article is protected by copyright. All rights reserved.

On behalf of the Advisory Board, I wish to congratulate the Integrative Zoology, on the 10th Anniversary of the journal Integrative Zoology. Ten years ago, in 2006, Integrative Zoology was launched as the new multidisciplinary flagship journal of the newly formed ISZS, and became central to our founding mission to promote zoology as an integrative discipline and to provide an attractive publishing venue for original research and reviews that present a broader perspective of zoological inquiry. Its debut issue, formed by a compilation of selected landmark papers from the first International Symposium of Integrative Zoology, are still some of the most downloaded and cited articles to this day...

In the new century, global change has become of the biggest challenges that threaten our ecosystem and society. Climate warming is causing range shifts of organisms which bring increased risk of species extinction in the polar regions, mountain tops or in fragmented habitats. Globalization is accelerating transmission of many infectious diseases and facilitating biological invasions, which have caused widespread damage to both ecosystems and human society. Solving these challenges urgently needs the application of integrative zoology...

The dynamics of red deer Cervus elaphus populations has been investigated across different environmental conditions, with the notable exception of the European Alps. Although the population dynamics of mountain-dwelling ungulates is typically influenced by the interaction between winter severity and density, the increase of temperatures and the reduction of snowpack occurring on the Alps since the 1980s may be expected to alter this pattern, especially in populations dwelling at medium-low elevations. Taking advantage of a 29-year time series of spring count data, we explored the roles of weather stochasticity and density dependence on growth rate and vital rates (mortality, weaning success), and the density-dependent variation in body mass in a red deer population of the Italian Alps...

Fertility control is an alternative strategy to traditional culling for the management of rodent pests. Previous studies have demonstrated that quinestrol is a potential contraceptive for male rodents, but the recovery of fertility in quinestrol-treated rodents has not been evaluated. This study used C57BL/6J mice to evaluate the recovery rate of male fertility after the administration of quinestrol. DES (diethylstilbestrol), a non-steroid estrogenic compound, was used for comparison. Different groups of mice were treated with 1 mg/kg quinestrol, 1 mg/kg DES, or castor oil separately for 7 days...

Whether or not sexually selected traits consistently exhibit positive allometry, i.e., are disproportionately large in larger individuals, is an ongoing debate. Multiple models and exceptions to this rule suggest that the underlying drivers of sexual trait allometry are nuanced. Here, we compare allometries of sexual and non-sexual traits of a species (Anolis aquaticus Taylor, 1956) within a well-studied lizard genus to test the competing hypotheses that sexual traits are, or are not, defined by positive allometry...

Survival and successful reproduction require animals to make critical decisions amidst a naturally dynamic environmental and social background (i.e., 'context'). However, human activities have pervasively, and rapidly, extended contextual variation into evolutionarily novel territory, potentially rendering evolved animal decision making mechanisms and strategies maladaptive. We suggest that explicitly focusing on animal decision making (ADM), by integrating and applying findings from studies of sensory ecology, cognitive psychology, behavioral economics and eco-evolutionary strategies, may enhance our understanding of, and our ability to predict how, human driven changes in the environment and population demography will influence animal populations...

Organisms on the rocky shore frequently suffer from high temperature, which consequently causes disability of cardiac function and retards the cellular oxygen delivery. However, some gastropods can survive in several Celsius degrees higher than their Arrhenius break temperature of cardiac function (ABT), indicating the importance of anaerobic metabolism for their thermal tolerance. We measured the global molecular responses to heat stress in limpet Cellana toreuma using 454 GS-FLX to investigate the variations of genes involving in anaerobic metabolism at high temperature...

The involvement of communities into ecological studies has been shown to augment conservation efforts, especially for cryptic species. However, there is a lack of studies addressing the utility of incidental sighting records from community members in gaining knowledge on habitat preferences and distribution of suitable habitat for these organisms. This study compares preferences of the Lumholtz's tree kangaroo (Dendrolagus lumholtzi; LTK), a cryptic rainforest folivore in North-Eastern Australia, for various habitat and climatic variables derived from data collected during scientific projects to those derived from incidental sighting records using ArcGIS and Maxent...

Deserts exhibit extreme climatic conditions. Small vertebrates have physiological and behavioral adaptations to cope with these conditions, including the ability to seek shelter. We investigated the temperature (T) and relative humidity (RH) regulating properties of soil cracks that characterize the extensive cracking-clay landscapes of arid Australia, and the extent of their use by two small marsupial species: fat-tailed and stripe-faced dunnarts (Sminthopsis crassicaudata Gould, 1844 and S. macroura Gould, 1845)...

Reproductive and life history patterns in reptiles are tightly related to the environmental conditions, so male reproductive cycles have been historically characterized as continuous, for tropical lizards, or seasonal, for temperate lizards. However, males of Liolaemus and Phymaturus lizards (Liolaemidae), from cold-temperate climates of high altitudes or latitudes in Argentina and Chile, have developed a variety of reproductive cycles to coordinate with the short female reproductive season and to deal with the low frequency of reproductive females in the population...

Kisspeptins and G protein coupled receptor (GPR54) play significant roles in regulating reproductive activity among seasonal reproductive animals; however, the mechanisms of KiSS-1 and GPR54 gene affecting the seasonal reproduction in striped hamster are still unknown. In this study, real-time quantitative PCR was employed to examine the expression profiles of KiSS-1 and GPR54 in the hypothalamus, ovarian, testis, uterus and epididymis of striped hamsters among four different seasons. Our results showed that, among different seasons, the KiSS-1 expression mode of male striped hamster and the GPR54 expression mode of female striped hamster were consistent with the seasonal photoperiod in the hypothalamus...

The Taebaek Mountains in South Korea serves as the most apparent biogeographic barrier for South Korean freshwater fishes, resulting in two distinct ichthyofaunal assemblages on the eastern (East/Japan Sea slope) and western (Yellow Sea and Korea Strait slopes) sides of the mountain range. Of nearly 100 species of native primary freshwater fishes in South Korea, only 18 species occur naturally on both sides of the mountain range. Interestingly, there are five rheophilic species (Phoxinus phoxinus, Coreoleuciscus splendidus, Ladislavia taczanowskii, Iksookimia koreensis and Koreocobitis rotundicaudata) found on both sides of the Taebaek Mountains that are geographically restricted to the Osip River (and several neighboring rivers, for L...
