δ 13C and δ 15N variation on guanacos in Tierra del Fuego: references for terrestrial foodwebs in a high-latitude island
(Springer, 2020-01)
The guanaco (Lama guanicoe) was a key staple hunted by foragers throughout the Holocene in southern South America. Stable isotope analyses provide insights about guanaco long-term ecology. Particularly, the characterization ...
Ecosystem fragmentation drives increased diet variation in an endemic livebearing fish of the Bahamas
(Wiley-Blackwell, 2014-08-01)
One consequence of human-driven habitat degradation in general, and habitat fragmentation in particular, is loss of biodiversity. An often-underappreciated aspect of habitat fragmentation relates to changes in the ecology ...

The dimensionality of individual niche variation
(2018-03-01)
The inherently multidimensional nature of the niche has not yet been integrated into the investigation of individual niche specialization within populations. We propose a framework for modeling the between- and within-individual ...
Individual niche trajectories drive fitness variation
(2019-09-01)
Variation in fitness across individuals is central to population growth, species coexistence and evolution by natural selection. Fitness variation associated with resource use is hugely consequential, but how this variation ...
The ecological causes of individual specialisation
(Wiley-Blackwell, 2011-09-01)
Many generalist populations are composed of specialised individuals, whose niches are small subsets of the population niche. This 'individual specialisation' is a widespread phenomenon in natural populations, but until ...
