Differential parental care behaviors of arboreal and terrestrial microhylid frogs from Papua New Guinea

I studied the ecology of parental care behaviors displayed by two closely related sympatric species of microhylid frogs in Papua New Guinea that occupy different microhabitats. Adult removal experiments on the terrestrial frog Hylophorbus rufescens and the undescribed arboreal frog Oreophryne sp. A demonstrate a significant positive effect of parental attendance on offspring survivorship and differential causes of egg mortality between microhabitats. Desiccation was the primary cause of egg mortality for the arboreal frog, whereas predation was the main source of mortality for the terrestrial frog. These selection pressures (desiccation and predation) are comparable to two of Wilsons prime movers of the evolution of parental care (harsh environment and predation) and may have driven and/or are maintaining the evolution of parental care behaviors in these Papuan microhylid frogs. These results highlight microhabitat-specific selection pressures in the evolution and maintenance of parental care behaviors.Communicated by A. Mathis     

浦东新区土壤—食物链中的铜锌

本文调查了浦东新区污灌区、吹泥区和一般区三种处理土壤中Ｃｕ、Ｚｎ的水平和垂直分布，Ｃｕ、Ｚｎ分层现象不明显，水平差异较大，但三种关型土壤差异不显著。Ｃｕ在食物链中累积系数铰小，一般小于１．０，而Ｚｎ的累积程度较大，尤其是以人为消费者的食物链中，累积系数最高达到１８。

New particle formation observed from a rain shadow region of the Western Ghats,India

Abstract

This study reports on new particle formation (NPF) and characteristic features observed from a rural site falling in the rainshadow of the Western Ghats in peninsular India. A total of 35 NPF events observed during August 2018 - January 2019 are classified and analyzed here. The apparent formation rates ranged from 0.2 to 10.0?cm^–3 s^–1, while the growth rates of nucleation mode particles ranged from 1.2 to 13.8?nm h^–1. The frequency of occurrence was least during August (core monsoon) and highest during post-monsoon. The local winds were calm and southeasterly to easterly (from the urban centre) supplying the essential precursor gases during October and November, leading to a frequent occurrence of nucleation events. Observations suggest that an increased condensation sink could limit the NPF while promoting Aitken mode growth. The newly formed particles accounted for about 10–80% of the total aerosol concentration. These newly formed particles were able to act as cloud condensation nuclei after growing to approximately 50?nm with an average activation fraction of 0.4.     

土地利用变化对城郊农业区生态效益的影响——以四川省南充市高坪区为例

借鉴生态效益综合评价的有关理论和数学模型,以四川省南充市高坪区为例,选取生物多样性指数、植被覆盖指数、水土保持效益指数、土壤改良指数、涵养水源指数、拦截径流指数和湿度指数7个指标作为评价因子,建立生态效益评价体系,对该区域1996和2005年2个时期综合生态效益进行评估和比较.结果表明,该区域综合生态效益值分别为7.85和7.95,2005年比1996年略为升高;基于GIS的图层叠置、分割等分析功能,就区域土地利用变化对其内部生态效益造成的变化进行了分析,该区域可被划分为生态效益显著增强区、增强区、保持区、减弱区和显著减弱区5个等级.     

Background levels of soil beryllium in several countries

Beryllium and aluminium contents in uncontaminated soils from six countries are reported. The means and ranges of beryllium in the surface soils were as follows: 1.43(0.20–5.50)g g^–1 in Thailand (n=28), 0.7 (0.31–1.03) g g^–1 in Indonesia (n=12), 0.99(0.82–1.32) g g^–1 in New Zealand (n=3), 0.58(0.08-1.68)g g^–1 in Brazil (n=16), 3.52(2.49–4.97)g g^–1 in the former Yugoslavia (n=10), and 1.56(1.01–2.73) g g^–1 in the former USSR (n=8). The mean and range of beryllium contents of the surface soils in Japan (1.17(0.27–1.95)g g^–1 n=27) are situated within the values of the soils from these countries except for the Yugoslav soils derived from limestones. The mean of the mean beryllium contents of the surface soils in all these countries is 1.42 g g^–1 which will be used as a tentative average content of beryllium in uncontaminated surface soils, except for the soils derived from parent materials high in beryllium content. The beryllium contents of the subsoils were higher than those of the surface soils in New Zealand and Yugoslavia as is the case with Japan. The correlation coefficient between the contents of beryllium and aluminium in all the soil samples (n=113) including surface soils and subsoils was 0.505 (p < 0.001).
