- Abstract:
- ... The influence of the biogeographical affinities of taxa on the spatial determinants of plant diversity remains largely unknown. I explored the spatial patterns of tropical and temperate plant diversity in Northwest Yunnan and their primary determinants. Generalized linear models (GLMs) and variance partitioning were used to investigate the influences of predictors. Temperate genus diversity signif ...

- Abstract:
- ... Among the different mechanisms that shape metacommunity structure, species sorting and mass effects are the most studied and reported mechanisms. Species sorting is related to environmental filtering, while mass effects are related to high dispersal between communities, which ultimately overrides environmental controls. In this paper, we aimed at studying metacommunity patterns of stream macroinve ...

- Abstract:
- ... Environmental adaptation and distribution of three annual plants, Impatiens noli-tangere, I. textori and Persicaria thunbergii, occurring in streamside environments were studied in Sapporo, northern Japan. Impatiens noli-tangere was found along steep streams as well as gentle streams, whereas I. textori and P. thunbergii were less frequent along steep streams than along gentle streams. Impatiens n ...

- Abstract:
- ... Most plant species display a certain degree of spatial aggregation that may play an essential role in plant community dynamics, e.g. in regulating the importance of interspecific competitive interactions. Here, the hypothesis that the degree of spatial aggregation may be regulated by environmental drivers such as nitrogen deposition or precipitation is tested. The degree of spatial aggregation of ...

- Abstract:
- ... This Paper examines how people's livelihoods and perceptions of wildlife are related to self-reported poaching (here defined as commercial bushmeat hunting) in 25 villages at the northern buffer zone of the Dja Biosphere Reserve, East Cameroon. Using a six-point Likert scale questionnaire among 263 households interviewed form March to June 2017, the following hypothesis were tested: (1) Households ...

- Abstract:
- ... Global atmospheric temperatures are predicted to rapidly increase within the next hundred years, consequently altering the microclimates of the sand dune environment where marine turtles lay their eggs. High nest temperatures can increase embryonic mortality, decrease hatchling vigour and size (i.e. quality), and also feminises the sex-ratio of clutches. Sand composition, vegetation cover, rainfal ...

- Abstract:
- ... The jaguar (Panthera onca) is widely distributed across a broad range of habitat types, where its feeding habits and habitat use patterns vary significantly. The jaguar and its main arboreal prey – the brown-throated sloth (Bradypus variegatus) and the red howler monkey (Alouatta juara) – are widespread in the Amazonian floodplain forests of the Mamirauá Reserve. These forest-dwelling species are ...

- Abstract:
- ... The increase use of Off-Road Vehicles (ORVs) coupled with the absence of control strategies have led to extensive use of natural areas for the creation of recreational trails. We assessed the effects of quad bikes on vegetation and soils in an arid ecosystem subjected to intensive quad bike use. We selected randomly eight traffic sites (disturbed sites) and eight adjacent control sites (undisturbe ...

- Abstract:
- ... Seasonal flood pulses drive important seasonal ecosystem changes, trigger ecological processes that control spatial and temporal distribution of organisms and their life-history strategies, and are considered a key ecological process shaping diversity in floodplains. We used generalized dissimilarity modelling (GDM) to analyse the relative importance of flooding as a driver of snake community comp ...
