Climatic niche attributes and diversification in Anolis lizards [PDF]

open access: yes, 2016
Aim The aim of this study was to test the link between climatic niche dynamics and species diversification in Anolis on islands and on the mainland. We tested the hypotheses that lineages in warmer climates and with narrow climate niches diversified ...

Cohabitation Study of Tricolour Langur (Presbytis chrysomelas ssp. cruciger) and Proboscis Monkey (Nasalis larvatus) in Bukit Semujan Danau Sentarum National Park

open access: yesJurnal Ilmu Kehutanan, 2023
The  tricolour langur and proboscis monkey in Bukit Semujan cohabited and utilized the same resources. Cohabitation, mainly due to resource constraints, needed substantial attention to ensure the survival of these primates. This research aimed to map the

Cultivation has selected for a wider niche and large range shifts in maize [PDF]

open access: yesPeerJ, 2022
Background Maize (Zea mays L.) is a staple crop cultivated on a global scale. However, its ability to feed the rapidly growing human population may be impaired by climate change, especially if it has low climatic niche and range lability.

On niche breadth and related concepts [PDF]

open access: yesBolletino di zoologia, 1990
Abstract Niche breadth values of three hypothetical resource matrices have been computed by means of four different formulae eventually giving rise to contrasting results. Starting from these results some remarks upon the niche breadth and related concepts are made. It is stressed, on the one hand, that any mathematical approach to the measure of niche

Reductions in the dietary niche of southern sea otters (Enhydra lutris nereis) from the Holocene to the Anthropocene. [PDF]

open access: yes, 2020
The sea otter (Enhydra lutris) is a marine mammal hunted to near extinction during the 1800s. Despite their well-known modern importance as a keystone species, we know little about historical sea otter ecology.

Impacts of Niche Breadth and Dispersal Ability on Macroevolutionary Patterns [PDF]

open access: yesThe American Naturalist, 2016
We describe a spatially explicit simulation experiment designed to assess relative impacts of macroecological traits on patterns of biological diversification under changing environmental conditions. Using a simulation framework, we assessed impacts of species' niche breadth (i.e., the range of their abiotic tolerances) and dispersal ability on ...

Retracted: Niches of nine mangrove species in a Sonneratia apetala‐colonized area of Dongzhai Harbor, Hainan Island, China

open access: yesEcology and Evolution, 2020
The distribution of mangroves is influenced by the environment. We aimed to understand the ecological adaptability of various mangrove species within the range of the exotic species, Sonneratia apetala Buch.‐Ham., in Dongzhai Harbor, Hainan Island, China.

Species traits and the form of individual species–energy relationships [PDF]

open access: yes, 2006
Environmental energy availability explains much of the spatial variation in species richness at regional scales. While numerous mechanisms that may drive such total species–energy relationships have been identified, knowledge of their relative ...

Ecology and co-existence of two endemic day gecko (Phelsuma) species in Seychelles native palm forest [PDF]

open access: yes, 2011
In island ecosystems, reptiles play diverse ecological roles as a result of niche broadening, which increases potential niche overlap between species. Ecological niche partitioning is a means of reducing direct competition between coexisting species and ...

Range Size and Niche Breadth as Predictors of Climate-Induced Habitat Change in Epipactis (Orchidaceae)

open access: yesFrontiers in Ecology and Evolution, 2022
While there is mounting evidence that ongoing changes in the climate system are shifting species ranges poleward and to higher altitudes, responses to climate change vary considerably between species. In general, it can be expected that species responses
