Exploring changes in mammalian population densities in response to humans

By Marlee Tucker

The world is changing. Humans have modified a large proportion of the Earth’s land surface through a range of activities such as urbanisation and the expansion of agriculture. In addition to landscape changes, the presence of...

Climate change - how much land do we need to protect to prevent mass extinctions?

For our latest Editor's choice paper, we present this video...

New range estimates for migrating monarch butterflies in Mexico: implementing and interpreting biotic variables and future conservation applications

By Jamie M. Kass, Verónica Juárez-Jaimes, José Juan Flores-Martínez, Víctor Sánchez-Cordero

Range estimates provide crucial and foundational information for conservation assessment and help to delimit areas for prioritization. Even for relatively...

E4 award papers over the years

The E4 Award is given every year to an early-career research scientist who writes an exceptional Review manuscript. The winner receives a 1000 cash prize and the runner-up...

20 000 years of african vegetation change

By Leanne Phelps

Understanding the effects of climate-disturbance-ecosystem interactions is essential for producing accurate predictions of vegetation change. Yet large uncertainties exist in future projections of biodiversity and ecosystem...

NSO journals in COVID-19 times

Dear authors, readers and reviewers,

As the world grapples with COVID-19 we write, above all, to wish you and those close to you continued good health.  These are uneasy times and we wanted to let you know that the editorial office of the Nordic Society Oikos (NSO) is...

European fish stocks on the move

Map of the northeast Atlantic showing the changes in spatial occurrence per species identified by the presence–absence analysis. In each ICES division, the results are showed with a petal plot. Each petal corresponds to a species, and these are ordered from top to bottom by...

Leveraging big citizen science data to understand urban tolerance of bird species

One thousand camera traps reveal that forest mammal communities have a consistent structure and similar vulnerability across the tropics

By Francesco Rovero

That biological communities in similar environments but distant regions share forms and functions is a known pattern of diversity attributed to convergent evolution. For tropical forest mammals, which include some of the most...

A temporal exploration of food webs using biomonitoring data

By Pierre Olivier

Since the very first representation of an ecological network (Camerano 1880), food webs have become an important tool to explore and summarize the...

Passerine assemblages show niche expansion from natural to urban areas

Pictures of six common passerine species in our study locations. Species were increasingly tolerant to habitat transformation from left to right. Left-up: Red-billed Leiothrix Leiothrix lutea. Left-down: Grey-cheeked Fulvetta Alcippe morrisonia. Middle-up...

Finding the ‘best’ habitat suitability model

By Edward Gregr and Kai Chan

How is a habitat model’s complexity related to its forecasting skill? Our recent Ecography paper addressed this question using multiple data...

Shorebirds are important plant vectors via endozoochory

Defaunation and fragmentation erode small mammal diversity dimensions in tropical forests

Figure 1: Best-fitting structural equation model (full direct + indirect model). Positive and negative pathways are indicated by black and gray lines, respectively. Arrow thickness is scaled to illustrate the relative strength of effects and significant coefficients are...

A parsimonious view of the parsimony principle in ecology and evolution

The curve-fitting problem. The choice of the most plausible hypothesis is based on an arbitrary balance between goodness-of-fit and simplicity criteria. The red curve is the simplest, indicating a linear relationship between the two variables, but also the worst-fit. The...
