This study is the first to describe quantitatively the apparent suckling behavior of sperm whale, Physeter macrocephalus (Linnaeus, 1758), calves using observations from both above and below the surface. Peduncle dives are short (mean 14 s) dives made by sperm whale calves beside the peduncle of an adult female, which were previously assumed to be indicative of suckling. Photo-identification an...

Objective: Drought stress is most important factor which reduce root and shoot growth in crops. This study was performed in order to evaluate the effects of drought stress and Zn fertilizer on root traits of four cultivars of chickpea. Methods: Experiment was laid out in a split plot-factorial using randomized complete block design with three replications. Drought stress treatment stand in main...

Antlion larvae of Cueta sauteri (Esben-Petersen) and Myrmeleon bore (Tjeder) from mainland China were collected in the field and reared to adults in the laboratory. Larval morphology of each species was described and complemented with behavioral observations. Their most important diagnostic characteristics are head capsule markings, mandibular length, mandibular teeth length, distance between m...

A new deep-sea stalked barnacle, Vulcanolepas scotiaensis sp. nov. is described from hydrothermal vents at depths of 2400-2600 metres along segments of the East Scotia Ridge and from 1400 metres in the Kemp Caldera. Both locations are areas of volcanic activity that lie on the Antarctic-South American Ocean Ridge complex near the South Sandwich Islands. This discovery confirms a wide distributi...

Hyphessobrycon klausannisp. n. is described from small drainages of the upper Guaviare River (Orinoco River Basin) in Colombia. It differs from all congeners by having a wide, conspicuous, dark lateral stripe extending from the anterior margin of the eye across the body and continued through the middle caudal-fin rays, and that covers (vertically) three or four horizontal scale rows. It also di...

Here we describe a new species of Biancolina from Pernambuco, Brazil, found in association with the brown algae Sargassum spp., between 0.5 and 1.0 m depth. The differs its congeners mainly by following combination characters: antenna 1 twice length 2, lacinia mobilis present both mandibles, article 4 maxilliped bulbose; coxa 6 anteroventral lobe well developed as posteroventral lobe, peduncle ...

A new bariline fish, Barilius kamjongensis is decribed from Kamjong district, the Chindwin basin of Manipur, India. It can be distinguished its congeners in having a body with 2 pairs barbels, 16–19 predorsal scales, 12–15 bars, 40–43 perforated lateral line 7.5/2.5 transverse origin dorsal-fin closed to base caudal-fin, pectoral-fin shorter than head length, depth at 22.8–26.6 % SL, caudal ped...
