Taxonomy and Translocations of African Mammals: A Plea for a Cautionary Approach

Conservation, Journal Year: 2021, Volume and Issue: 1(2), P. 121 - 136

Ecotourism can fuel an important source of financial income for African countries and therefore help biodiversity policies in the continent. Translocations be a powerful tool to spread economic benefits among communities; yet, positive conservation, they require basic knowledge conservation units through appropriate taxonomic research. This is not always case, as taxonomy was considered outdated discipline almost century, some plurality approaches incorrectly disadvantage work. As example, diversity genus Giraffa its recent history illustrate importance such sound policy that includes translocations. We argue fine-grained perspective prioritizes all remaining populations along Nile Basin needed. are tools giraffe but more discussion needed, especially moving new giraffes regions where autochthonous taxa/populations no longer existent. current about too focused on number species, we might beneficial, i.e., defining requiring separate management using (majority) consensus across different concepts (e.g., MU—management unit, ESU—evolutionary significant ECU—elemental unit). The taxonomically sensitive translocation policy/strategy would preservation diversity, while also supporting ecological restoration within rewilding. A summary table main operations mammals have underlying problems included. Therefore, call increased attention toward only basis further opportunity enlarge geographic scope ecotourism Africa.

Growing up in a new world: trait divergence between rural, urban, and invasive populations of an amphibian urban invader

Cities are focal points of introduction for invasive species. Urban evolution might facilitate the success species in recipient urban habitats. Here we test this hypothesis by rearing tadpoles a successful amphibian coloniser and invader common garden environment. We compared growth rate, morphological traits, swimming performance, developmental rate guttural toad ( Sclerophrys gutturalis ) from native rural, urban, non-native By measuring these traits across ontogeny, were also able to compare divergence different origins as develop. The origin showed significantly slower (e.g., proportion reaching Gosner stage 31 or higher was lower at age 40 days) than origin. Yet, did not differ any performance trait examined, none divergent ontogenetic changes between These findings suggest that prior adaptation habitats larval likely does play an important role facilitating invasion toads into other Instead, evolutionary after colonization rate), together with decoupling phenotypic plasticity explain how succeeded colonising extra-limital

Review of range extensions of tropical brachyuran crabs into temperate waters of southern Africa

Crustaceana, Journal Year: 2021, Volume and Issue: 94(10), P. 1235 - 1262

Published: Oct. 27, 2021

Abstract We compiled known occurrence records of seven species crabs identified in the literature and one documented this report as having undergone range extensions southern Africa. Of these eight species, six ( Austruca occidentalis , Neosarmatium africanum Ocypode ceratophthalmus Portunus segnis Tubuca urvillei Varuna litterata ) have extended their ranges either across a major biogeographic boundary that separates subtropical warm temperate ecoregions coast, or into estuaries historically lack mangrove forests. For seventh eighth Charybdis smithii Scylla serrata we were unable to find any distributional data supported poleward extension. In addition, contribute first record blue swimming crab, P. from south coast South This early detection is likely be part an ongoing regional trend tropical-adapted brachyuran crab extending ecoregions.
