Twenty one jumping spider species from South Yunnan are reported, diagnosed, described and illustrated; 19 of them are described as new: Afraflacilla ballarini Cao & Li, sp. n. (♂), Agorius tortilis Cao & Li, sp. n. (♂♀), Bavia exilis Cao & Li, sp. n. (♂), Carrhotus kevinlii Cao & Li, sp. n. (♂♀), Carrhotus sarahcrewsae Cao & Li, sp. n.

We here describe the endocranial cast of the Eocene archaic ungulate Hyopsodus lepidus AMNH 143783 (Bridgerian, North America) reconstructed from X-ray computed microtomography data. This represents the first complete cranial endocast known for Hyopsodontinae. The Hyopsodus endocast is compared to other known "condylarthran" endocasts, i. e. those of Pleuraspidotherium (Pleuraspidotheriidae), A...

23 In the San Francisco Estuary, management actions including tidal marsh restoration could 24 change fish mercury (Hg) concentrations. From 2005 to 2007, small forage fish were 25 collected and analyzed to identify spatial and interannual variation in biotic 26 methylmercury (MeHg) exposure. The average whole body total Hg concentration was 27 0.052 µg g-1 (wet weight) for 457 composite sample...

— New synonymy is proposed as follows: Pityokteines Fuchs { = Orthotomides Wood), Araptus foveifrons (Schedl) { = interjectus Wood), n. comb., Cryptocarenus seriatus Eggers { = bolivianus Eggers), Hylastes gracilis LeConte {=asper Swaine), Procryphalus utahensis Hopkins {=aceris Hopkins), Scolytodes maurus (Blandford) {=Hexacolus ellipticus Eggers), Scolytus hermosus Wood {=sylvaticus Bright), ...

The relative importance of plant facilitation and competition during primary succession depends on the development of ecosystem nutrient pools, yet the interaction of these processes remains poorly understood. To explore how these mechanisms interact to drive successional dynamics, we devised a stoichiometric ecosystem-level model that considers the role of nitrogen and phosphorus limitation in...

Bats are of high conservational status in most European countries. All bats under legal protection Ukraine and included the national Red Data Book. However, remain one least studied groups mammals Ukraine. Their cryptic lifestyle limits possibilities direct observations and, as a result, data on bat distribution incomplete. Wildlife rehabilitation centres accumulate plethora records wild animal...
