Saúl López-Alcaide, Miguel Nakamura, Eric N Smith, Enrique Martínez-Meyer
Sceloporus lizards depend on external heat to achieve their preferred temperature (Tse1 ) for performing physiological processes. Evidence both in the field and laboratory indicates that pregnant females of this genus select body temperatures (Tb ) lower than 34°C as higher temperatures may be lethal to embryos. Therefore, thermoregulation is crucial for successful embryo development. Given the increase in global air temperature, it is expected that the first compensatory response of species that inhabit tropical climates will be behavioral thermoregulation...

Several specimens of the giant deep-sea isopod genus Bathynomus were collected by a deep-sea lander at a depth of 898 m from Hainan Island, northern South China Sea. After careful examination, this material and the specimens collected from Gulf of Aden, north-western Indian Ocean, previously reported as Bathynomus sp., were identified to be the same as a new species to the genus. Bathynomus jamesi sp. nov. can be distinguished from the congeners by the distal margin of pleotelson with 11 or 13 short straight spines and central spine not bifid; uropodal endopod and exopod with distolateral corner slightly pronounced; clypeus with lateral margins concave; and antennal flagellum extending when extended posteriorly reaches the pereonite 3...

Understanding the factors that lead to variation in the timing of breeding in widespread species such as red deer (Cervus elaphus L.) is crucial to predict possible responses of wild populations to different climate scenarios. Here, we sought to further understand the causes of inter-annual variation in the reproduction timing of female deer in Mediterranean environments. An integrative approach was used to identify the relative importance of individual, population and climate traits in the date of conception of free ranging deer, based on a dataset of 829 hinds culled during 12 years...

REVIEW
David T Booth
Since the 1980s it has been known that incubation temperature influences the sex ratio of sea turtle hatchlings emerging from their nests, and there has been much speculation on how global climate change might threaten sea turtle populations by raising nest temperatures and causing highly female biased hatchling sex ratios. More recently, studies have indicated that incubation temperature can also influence the size and locomotor performance of sea turtle hatchlings. Here I review recent studies that have explored the influence of incubation temperature on sea turtle hatchling quality in terms of hatchling morphology and locomotor performance...

Rodents, including common voles (Microtus arvalis Pallas, 1778) and house mice (Mus musculus Linnaeus, 1758) cause immense pre- and post-harvest losses. Therefore, developing methods that mitigate these losses while maintaining their role in ecosystems is a priority. Several plant secondary metabolites (PSMs) which significantly reduce food intake of both species under laboratory conditions have been identified. However before these can be used in rodent pest management, they must be tested under more natural conditions where other food sources are available...

Rodents are globally important pre-harvest pests of rice. In South-east Asia, rodent damage to growing rice crops is commonly concentrated towards the center of rice fields, away from the field edge resulting in a clear pattern known as the 'stadium effect'. To further understand this behavior of rodent pests and develop recommendations for future research and management, we examined the relation between giving-up densities (GUDs) and damage patterns. In Tanay, Luzon, Philippines, GUD trays containing pieces of coconut in a matrix of sand were placed at four different distances from the field edge to quantify the perceived risk of predation in a rice field pest, Rattus tanezumi...

Temperature is a critical factor influencing avian phenology, due to its direct impact on food and water availability. Most previous studies have focused on the timing of spring migration and arrival of birds at breeding grounds along the European and American flyways; little is known about migration ecology at the wintering sites along the Asian flyways. This study investigates how local temperature variation and EI Niño Southern Oscillation (ENSO) influences the arrival and departure timing of nine waterbird species breeding in Mongolia or Siberia and overwintering in Poyang, China from 2002 to 2013, using linear regression models...

The means of orientation is studied in the Vietnamese pygmy dormouse Typhlomys chapensis, a poorly known enigmatic semi-fossorial semi-arboreal rodent. Data on eye structure are presented, which prove that Typhlomys (translated as "the blind mouse") is incapable of object vision - the retina is folded and retains no more than 2 500 ganglion cells in the focal plane, and the optic nerve is subject to gliosis. Hence, Typhlomys has no other means for rapid long-range orientation among tree branches other than echolocation...

Acute cold exposure may disturb physiological homeostasis of the body in ectotherms. By now, there is no information about the effects of cold exposure on homeostasis of reactive oxygen species (ROS) or antioxidant defense response in the Chinese soft-shelled turtle, Pelodiscus sinensis. In this study, P.sinensis juveniles were acclimated at 28 °C, transferred to 8 °C as cold exposure for 12 hours, moved back to 28 °C rewarming for 24 hours. We measured ROS level and total antioxidant capacity (TAC) in the brain, liver, kidney and spleen at 2 hours, 12 hours cold exposure, and the end of rewarming...

The crucial step of most of the current genetic studies is the extraction of DNA with sufficient quantity and quality. Several genomic DNA isolation methods have been described to successfully obtain male DNA from shrimp species. However, all current protocols require invasive handling methods on males for DNA isolation. Using Aristeus antennatus as a model we tested a reliable non-invasive differential DNA extraction method to male DNA isolation from spermatophores attached to female thelycum. The present protocol provides high quality and quantity DNA for PCR amplification and male genotyping...

There are many locations in Russia where Eurasian beaver (Castor fiber) populations have been restored. As a keystone species, beavers provide wide-ranging direct and indirect impacts on aquatic ecosystems. In particular, beaver-created ponds are sites for spawning and nursery places for tadpoles of the brown frog (genus Rana). Because of such impacts, study techniques for assessing aquatic organisms abundance are being developed. We compared two methods for estimating tadpole abundance: traditional catches by dipnet and electrofishing...

Curious eroded depressions, most resembling an eye shedding an elongate tear, are found in gently sloping, intertidal, carbonate-rich arenite outcropping on the sea coast near Lakes Entrance, Victoria, SE Australia. The depressions, known locally as "Tears of the Virgin", are evidently formed by multiple generations of a barnacle, Chthamalus antennatus Darwin, 1854 in association with cyanobacteria.  While the round part of a depression offers the barnacle a modicum of protection from impacts during high tides, it is also partially inhabited by cyanobacteria, which extend into and tend to fill the elongate tear...

The phylogenetic relationships among imported ornamental crayfish belonging to the genus Cherax were inferred from a combined dataset of 3 mitochondrial genes (COI, 16S and 12S) and by comparison with available GenBank sequences of 14 Cherax species. Furthermore, the concordance of previously described species obtained from a wholesaler (Cherax boesemani, C. holthuisi and C. peknyi) with available GenBank sequences was verified based on COI with special respect to comparison with sequences assigned as Cherax species...

George O Batzli
Increased habitat fragmentation leads to smaller size of habitat patches and to greater distance between patches. The ROMPA hypothesis (ratio of optimal to marginal patch area) uniquely links vole population fluctuations to the composition of the landscape. It states that as ROMPA decreases (fragmentation increases), vole population fluctuations will increase (including the tendency to display multi-annual cycles in abundance) because decreased proportions of optimal habitat result in greater population declines and longer recovery time after a harsh season...
