Stable isotope records of nursing and weaning: A case study in elephants with implications for paleobiological investigations Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 2.833) Pub Date : 2021-01-23 Michael D. Cherney; Daniel C. Fisher; Michael T. Hren; Ethan A. Shirley
Nursing and weaning are behaviors that are central to the growth of offspring and success of mammal populations. The duration of nursing and timing of weaning are essential elements of a species' life history, but they are also somewhat plastic; weaning age increases during intervals of drought or other dietary stress. Thus, weaning age provides a proxy for nutritional stress in an extinct population

Although the effectiveness of windbreaks in reducing wind speed and sediment transport is highly dependent on the efficiency of individual elements, few field studies have evaluated the effectiveness of single plants typical of arid areas such as Tamarix. A series field experiments were conducted in the Niatak area of Sistan to assess the effectiveness of a single Tamarix tree in reducing wind speed

Carbon budget response of an agriculturally used fen to different soil moisture conditions Agric. For. Meteorol. (IF 4.651) Pub Date : 2021-01-23 Sonja Paul; Christof Ammann; Christine Alewell; Jens Leifeld
The agricultural use of peatlands usually requires drainage, thereby transforming these organic soils from a net carbon sink into a net source. The Seeland region of Switzerland is characterised by fens that have been intensively used for agriculture for 150 years. Our site is a degraded fen with a remaining peat layer of 60 cm that had been used as cropland until 2009. In connection to a nature protection

Impacts of deep-rooted fruit trees on recharge of deep soil water using stable and radioactive isotopes Agric. For. Meteorol. (IF 4.651) Pub Date : 2021-01-23 Peijun Shi; Yannan Huang; Wangjia Ji; Wei Xiang; Jaivime Evaristo; Zhi Li
Deep-rooted fruit trees mine more water from deep soils than their shallow-rooted counterparts. Understanding how deep soil water (DSW) is replenished and subsequently depleted by deep-rooted fruit trees, therefore, are important for informing sustainable water resources management particularly in arid regions. In this study, we collected soil samples from the surface down to 20 m under four land use

Neural network prediction of the topside electron content over the Euro-African sector derived from Swarm-A measurements Adv. Space Res. (IF 2.177) Pub Date : 2020-12-28 Ola A. Abuelezz; Ayman M. Mahrous; Pierre J. Cilliers; Rolland Fleury; Mohamed Youssef; Mohamed Nedal; Ahmed M. Yassen
This study presents the first prediction results of a neural network model for the vertical total electron content of the topside ionosphere based on Swarm-A measurements. The model was trained on 5 years of Swarm-A data over the Euro-African sector spanning the period 1 January 2014 to 31 December 2018. The Swarm-A data was combined with solar and geomagnetic indices to train the NN model. The Swarm-A

Investigation of the characteristics of wavelike oscillations of post-sunset equatorial ionospheric irregularity by decomposing fluctuating TEC Adv. Space Res. (IF 2.177) Pub Date : 2020-12-03 Asfaw Merid; Melessew Nigussie; Atalay Ayele
Post-sunset ionospheric irregularities are common features of the equatorial ionosphere that affect radio communication and navigation systems; their triggering physical mechanism is not yet fully understood. Atmospheric gravity wave is considered as a seeding mechanism for the occurrence of ionospheric irregularities (Abdu et al., 2009). To understand the effects of atmospheric waves, characteristics

Responses of the African equatorial ionization anomaly (EIA) to some selected intense geomagnetic storms during the maximum phase of solar cycle 24 Adv. Space Res. (IF 2.177) Pub Date : 2020-12-07 O.J. Oyedokun; A.O. Akala; E.O. Oyeyemi
This study investigates the morphology of the GPS TEC responses in the African Equatorial Ionization Anomaly (EIA) region to intense geomagnetic storms during the ascending and maximum phases of solar cycle 24 (2012–2014). Specifically, eight intense geomagnetic storms with Dst ≤ −100 nT were considered in this investigation using TEC data obtained from 13 GNSS receivers in the East African region
