Spatial mechanisms promoting plant coexistence. the role of dispersal and competition [PDF]

open access: yes, 2009
One of the great challenges in ecology is to explain how large numbers of plant species are able to coexist in natural communities. The role of spatial structure for maintaining plant coexistence has so far mainly been explored by theory.

Finding a Home: Stopping Theory and Its Application to Home Range Establishment in a Novel Environment

open access: yesFrontiers in Conservation Science, 2021
Familiarity with the landscape increases foraging efficiency and safety. Thus, when animals are confronted with a novel environment, either by natural dispersal or translocation, establishing a home range becomes a priority.

Low rate of between-population seed dispersal restricts genetic connectivity and metapopulation dynamics in a clonal shrub [PDF]

open access: yes, 2012
Clonal species normally have low seed production, low recruitment rates and long lifespans, and it is expected that the rates of long-distance dispersal (LDD) of seeds will be low as well. Banksia candolleana is a clonal shrub in Mediterranean-type, fire-

Isatxo/Seed-dispersal-disruptions: [PDF]

open access: yes, 2021
Review of studies on biotic and abiotic seed dispersal disruptions to ascertain the global change drivers addressed, dispersal modes impacted, plant processes affected, and spatial focus of existing research on this topic up-to ...

Development of morphology and swimming in larvae of a coral-reef fish, the royal gramma, Gramma loreto (Grammatidae: Teleostei)

open access: yesScientia Marina, 2012
We used reared larvae of Gramma loreto sized 5.5 to 10.5 mm to study ontogeny of morphology and swim- ming. The larvae are slender to moderate in depth, with laterally compressed bodies, about 28 myomeres, a coiled gut that is not compact, extending to

Conservation Actions in Multi-Species Systems: Species Interactions and Dispersal Costs

open access: yesFrontiers in Ecology and Evolution, 2021
We use the General Equilibrium Ecosystem Model (GEEM) parameterized to Wyoming sagebrush to explore the impact of two common simplifications in bio-economic policy frameworks on species conservation decisions.

Life path analysis: scaling indicates priming effects of social and habitat factors on dispersal distances [PDF]

open access: yes, 2001
1. Movements of many animals along a life-path can be separated into repetitive ones within home ranges and transitions between home ranges. We sought relationships of social and environmental factors with initiation and distance of transition movements

Attachment sites of generalist ticks on birds depend on environmental factors (habitat and season) rather than on tick species

open access: yesTicks and Tick-Borne Diseases
The aim of this investigation was to analyze predilection sites of ticks on avian hosts according to tick species and developmental stages, as well as individual and ecological characters of bird species (i.e., their age, habitat type, seasonality).

Zooplankton biodiversity and community structure vary along spatiotemporal environmental gradients in restored peridunal ponds

open access: yesJournal of Limnology, 2015
Zooplankton assemblages in neighboring ponds can show important spatial and temporal heterogeneity. Disentangling the influence of regional versus local factors, and of deterministic versus stochastic processes has been recently highlighted in the ...
