We report the first record of Hairy-tailed Moles (Parascalops breweri) moving above ground during the day and suggest that the four individuals observed were young-of-the-year dispersing from their natal territories. Extreme drought conditions may also have driven these animals to move above ground.

The Mediterranean

The islands of Tinos and Syros in the Cyclades Archipelago, Greece, have a hilly terrain, a mild Mediterranean climate and vegetation adapted to drought conditions. Caper (<em>Capparis</em> <em>spinosa</em> L.) is highly adapted to arid environments and grows successfully during the Mediterranean summer. In August 2015, we detected serious infestations on wild caper by <em>Eurydema</em> <em>eckerleini</em> (Pentatomidae), which was formerly considered a species endemic to Crete and the Peloponnese, with an isolated report in Turkey. This is the first record of the presence of<em> E. eckerleini</em> in the Cyclades.

The Status

Recently, the signs of extreme droughts, which were thought of as exceptional and unlikely, are being detected worldwide. It is necessary to prepare countermeasures against extreme droughts; however, current definitions of extreme drought are just used as only one or two indicators to represent the status or severity of a drought. More representative drought factors, which can show the status and severity that are relevant to extreme drought, need to be considered depending on the characteristics of the drought and comprehensive evaluation of various indices. Therefore, this study attempted to quantitatively define regional extreme droughts using more acceptable factors. The methodology comprises five factors that are indicative of extreme drought. The five factors are (1) duration (days), (2) number of consecutive years (years), (3) water availability, (4) return period, and (5) regional experience. The results were analyzed by applying the procedure to droughts that took place in 2014–2015 in South Korea. The results showed that the applied historical event did not enter the status of extreme drought, which is proposed in this study; however, the proposed methodology is applicable because it uses acceptable and reasonable factors to judge extreme drought, but it can also take into account the past regional experience of extreme drought.

A small school of juvenile Atlantic Whitefish (~20-30 individuals) were observed in the littoral zone of Hebb Lake (Petite Rivière watershed), Nova Scotia in June 2000. Of these, a single individual was captured with a beach seine, and confirmed to be a young-of-the-year specimen. This is the first documented report of the occurrence of wild Atlantic Whitefish juveniles. Occupation of the littoral zone into early summer by young-of-the-year Atlantic Whitefish may have implications for predation by invasive Smallmouth Bass.

Abstract This paper presents the first record of fire in Pacific coast salt marshes; the 1993 Green Meadows Fire and the 2013 Camarillo Springs Fire burned an area of Salicornia-dominated salt marsh at Point Mugu, CA. These fires inspire concern about resiliency of ecosystems not adapted to fire, already threatened by sea-level rise (SLR), and under stress from extreme drought. We monitored vegetation percent cover, diversity, and soil organic carbon (SOC) in burned and unburned areas of the salt marsh following the 2013 Camarillo Springs Fire and used remotely sensed Normalized Vegetation Difference Index (NDVI) analysis to verify the in situ data. Two years following the fire, vegetation percent cover in burned areas was significantly lower than in unburned areas, with dominant-species change in recovered areas, and NDVI was lower than pre-fire conditions. Multi-year disturbance, such as fire, presents challenges for salt marsh resilience and dependent species, especially in sites facing multiple stressors. With anticipated higher temperatures, increased aridity, extreme drought, and higher frequency fires becoming a reality for much of the Pacific coast, this study indicates that fire in Salicornia-dominated marshes is a vulnerability that will need to be addressed differently from other grass- or reed-dominated marsh systems.

In Cape Town we have been experiencing the most severe drought in our history. We are not alone.Other cities – for example, in the United States, Brazil, Spain, Belgium, Australia, Morocco andPakistan – are also learning to live under new, more extreme, drought conditions. In this article Iuse the local drought as an aperture through which to identify key insights into how adult learningand education (ALE) can and should respond in times of climate crisis. The article is exploratory, asthe ambitious topic opens up a raft of complex economic, socio-ecological and political issueswhich can only be touched upon. It aims to prompt deeper conversations about ALE and climatecrises and to identify key questions for future ALE research.

ABSTRACTCongenital deformities are relatively common in rays and sharks. The present study aimed to describe a case of bicephaly in an R. lalandii embryo. Through radiographic images and evaluation of the external and internal condition of the embryo in comparison with a young of the year with no deformities of the same species, it was possible to characterize the abnormality observed. Such data are important to determine the frequency and types of anomalies observed in elasmobranchs, thusallowing greater knowledge about developmental abnormalities in the group and their possible causes. RESUMODeformidades congênitas são relativamente comuns em raias e tubarões. O presente estudo teve como objetivo descrever um caso de bicefalia em um embrião de R. lalandii. Através de imagens radiográficas e avaliação da condição externa e interna do embrião em comparação com um jovem do ano sem deformidades da mesma espécie, foi possível caracterizar a anormalidadeobservada. Tais dados são importantes para determinar a frequência e tipos de anomalias observadas em elasmobrânquios, permitindo assim o maior conhecimento sobre as anormalidades de desenvolvimento no grupo e suas possíveis causas.Palavras-chave: Malformação; Tubarão; Espécie endêmica; Morfologia.
