Broadley was one of Africa’s most prolific recent authors. He produced over 410 articles, including numerous comprehensive and detailed taxonomic reviews of lizard and snake genera. A review of his scientific publications spanning over 50 years of herpetological research reveals three phases. The first (1958–1981) saw Don describe his first new reptile and the completion of numerous important generic revisions. The second phase (1982–1991) was a period of relative taxonomic quiescence, but saw the compilation of major faunal overviews, including two books, the monographic Amphibia Zambesiaca (with J.C. Poynton, 1985–1991), and a checklist of the reptiles of Tanzania (with Kim Howell, 1991). The third and final phase of Don’s career (1992–2015) saw him at the peak of both his collaborative and authoritative stage. His outlook embraced sub-Saharan Africa, although always with a bias towards eastern and southern Africa. Appendices include: a detailed bibliography of his herpetological publications; a chronological list of all the scientific taxa he described; and details of the numerous current patronyms named in his honour. He described 123 taxa, including 115 species/subspecies and 8 genera/subgenera. As of 2016 there are 16 patronyms (five amphibians, nine reptiles and two invertebrates) named in his honour.","PeriodicalId":49247,"journal":{"name":"African Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2018-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/21564574.2017.1349004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44335366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the concept of this genus has been confounded by morphological and genetic differences between the constituent taxa. Due to the dearth of DNA samples, a taxonomic assessment has been impractical to date. We therefore sequenced two mitochondrial and one nuclear marker (16S, cyt b, and c-mos) from 45 samples representing ten species of Gonionotophis to construct a molecular phylogeny using Bayesian and likelihood approaches. Four divergent and well-supported clades were recovered, including: (1) grantii + brussauxi; (2) poensis + stenophthalmus; (3) nyassae; and (4) capensis, chanleri, crossi, guirali and savorgnani. Based on these results and morphological data, the genus Gonionotophis is restricted to the first clade, Mehelya is resurrected for the species in the second clade, and new genera are described for the remaining two clades.

Here, we review the diet of cape cobras (Naja nivea) based on examination of museum specimens, an extensive literature review, and social media reported natural history observations. We quantify dietary niche breadth and test the hypothesis that cape cobras are generalist predators. Additionally, we test the hypotheses that diet varies significantly (1) across biomes, and (2) across winter, summer and year-round rainfall regions. We gathered 101 feeding records for cape cobras and based on family-level prey frequencies calculated Levins’ measure of niche breadth as B = 6.57, which we standardised to BA = 0.29. We found no association between prey classes and biomes or rainfall region. Our data indicate that cape cobras consume a wide range of vertebrate prey from all four tetrapod classes, including a large number and diversity of snakes. Our findings suggest that cape cobras may be involved in several important ecological processes. Moreover, our study demonstrates the utility and value of collating natural history observations reported on social media platforms.","PeriodicalId":49247,"journal":{"name":"African Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/21564574.2017.1388297","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47054614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this region, 33 sites were surveyed over the late winter and spring for a period of three years. Salamandra algira was present at 16 of these sites and absent from 17. These sites were characterized based on parameters related to their macroecology (climate, topography) and habitat structure (density, height, canopy closure and diversity of woody plants). Our analyses showed that mean temperature, topography, woody plant density and height and canopy cover contributed most to the explaining differences between sites where S. algira was present and where it was absent. Most of the sites occupied by S. algira were supra- and meso-Mediterranean forest thermotypes and were dominated by deciduous/evergreen oak trees (Quercus canariensis Willd. and Quercus suber L.). In contrast, the presence of S. algira in thermo-Mediterranean forest was only confirmed in one location. This suggests that the transition between the thermophilic facies of the cork oak forest and the thermo-Mediterranean formations possibly determines the lower limits of S. algira in the region of Edough.","PeriodicalId":49247,"journal":{"name":"African Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/21564574.2017.1388855","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45535987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The animals are constrained by wet (from September until May) and dry (from June until August) seasons, however, the sexual cycle of males is continuous (all germ cells categories are present throughout the year). The aim of this study was to follow the changes in the reproductive organs of male toads during the annual breeding cycle using light microscopy. Our study was conducted over the period 2003 to 2005. The surfaces of testicular sections, interstitial tissue and Leydig cells, as well as the number of total seminiferous tubules with spermatozoa in bundles, were analysed. All showed monthly variations throughout the annual breeding cycle. For each year, the surface of testis sections and the number of spermatozoa in bundles fluctuate in the same way throughout the year, with a strong increase during the dry season (maximum in August) and a slow decrease until January. The surface of interstitial tissue remained stable, with the exception of a strong peak in August. Additionally, the surface of Leydig cells showed a substantial peak in May before the dry period. Finally, testosterone was observed every month of the year.","PeriodicalId":49247,"journal":{"name":"African Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/21564574.2017.1369170","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47919667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found strong differences between seasons, and effects of weather, individuals and sex. The high activity was consistent with mild weather during autumn and spring. However, daily temperatures limited female movements on cool autumn days and male movements on warm spring days, a pattern consistent with sexual size dimorphism (large females and small males). The long movements in autumn probably helped tortoises find food plants that grow quickly after autumn rains; both sexes recover body condition from autumn lows, and females begin egg production in late-autumn and winter. These movements may also help males mate with females before they ovulate. The high activity of females in spring should help them forage and sustain their vitellogenesis, egg production and nesting in spring. Male paths tended to be more linear than female paths in both seasons, so this sexual difference is likely not linked to food consumption. Males may move long, linear paths to engage females and avoid other males. Males may have been thermally-challenged in spring. Their movements decreased with increased ground temperatures (in the sun), they used denser refugia in spring than in autumn, and in spring used denser refugia than females used. Geometric tortoises typically used different refugia on consecutive nights, a type of predator avoidance mechanism.","PeriodicalId":49247,"journal":{"name":"African Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/21564574.2017.1331935","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46639615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It contained 21 adult males and females. Each was marked with a transponder so that the behaviour of individuals could be tracked. The animals inhabited the bottom of the pond. They were active from dusk to midnight. Series of nights in which several males called alternated with series without calling. Simultaneous calls were not synchronised. On nights when males called, several of them established territories on the bottom of the pond that they defended against other males. They delineated the territory by calling along its borders. When meeting a male intruder they emitted an encounter call, followed by a fighting call if they fought. At the end of a fight the loser emitted a release call. Territories could remain constant over several weeks. They were abandoned on nights without calling, but re-established by the same individuals at the same locations on nights with calling. When a female entered a territory, the male approached, started the courtship call and attempted amplexus. The female usually rejected the male while emitting a release call. Females spawned synchronously on one or two nights, with weeks without oviposition in-between. Eggs were laid individually or in small groups on hard structures all over the pond. The adults preyed upon the tadpoles and only a few single tadpoles remained after two weeks. Raising the water level stimulated calling activity.","PeriodicalId":49247,"journal":{"name":"African Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/21564574.2017.1381649","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44020019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
