A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

open access: yesPlant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Nature’s Eden? The Production and Effects of ‘Pristine’ Nature in the Galápagos Islands [PDF]

open access: yesIsland Studies Journal, 2011
Best known for inspiring Charles Darwin's theory of evolution, the Galápagos Islands are often referred to as an “evolutionary Eden” and celebrated as one of the world’s few remaining bastions of “pristine” nature. However, recent concerns of a crisis of

Biogeography of Parasitic Nematode Communities in the Galápagos Giant Tortoise: Implications for Conservation Management.

open access: yesPLoS ONE, 2015
The Galápagos giant tortoise is an icon of the unique, endemic biodiversity of Galápagos, but little is known of its parasitic fauna. We assessed the diversity of parasitic nematode communities and their spatial distributions within four wild tortoise ...

Relationships Between Oceanic Primary Production, Human Habitation and Variation in the Life‐History Traits of Coral Reef Fishes Across the Northern Line Islands

open access: yesFish and Fisheries, Volume 27, Issue 6, Page 1269-1282, November 2026.
ABSTRACT Biophysical processes associated with large‐scale nearshore oceanographic upwelling can influence coral reef communities by increasing the delivery of nutrient subsidies and food resources to reefs. However, these processes occur alongside anthropogenic activities that may alter ecological patterns across coral reef ecosystems.

Helminth parasites of Galápagos mammals: a new cestode of the genus Raillietina from the endemic rice rat Nesoryzomys swarthi and a summary of parasites from both endemic and invasive rodents

open access: yesParasitology
In this first report of endoparasites from endemic land-mammals of the Galápagos Islands, we describe a new species of cestode of the genus Raillietina (Cyclophyllidea: Davaineidae) from a species of Nesoryzomys and summarize the extent of helminth ...

Flight of the dragons: a global review of migration in Odonata

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2134-2157, October 2026.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

Darwin and the plants of the Galapagos-Islands [PDF]

open access: yes, 2009
During his five year sea voyage with the “Beagle”, Darwin, at the suggestion of the botanist J.S. Henslow, collected more than 1400 vascular plants, and more than 200 of them alone during his short stay on the Galápagos Islands.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2190-2213, October 2026.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Epipelagic copepod distributions in the eastern equatorial Pacific during the weak La Niña event of 2001

open access: yesScientia Marina, 2011
We determined the distribution and abundance of pelagic copepods in the eastern equatorial Pacific between the coast of Ecuador and the Galapagos Islands under oceanographic conditions associated with the weak La Niña event of 2001.

Surface and Tropospheric Climatic Trends in the Galápagos Archipelago Based on the Galápagos Archipelago Refined Analysis Dataset

open access: yesInternational Journal of Climatology, Volume 46, Issue 12, October 2026.
The Galápagos Archipelago's near‐surface climate is primarily influenced by interannual El Niño‐Southern Oscillation variability, with no statistical evidence for long‐term trends in air temperature, humidity, or precipitation. While tropospheric warming and increased atmospheric stability are observed, these trends are largely decoupled from near ...
